Operation Instruction

I/O Settings

Communication mode
The communication interface is J1. This module has two communication interfaces that cannot be used at the same time: UART and I2C interface. The module has three communication modes, namely: automatic detection mode, UART communication mode and I2C communication mode. The automatic detection mode belongs to the factory configuration of the module. After the module is powered on (or reset), it takes about 7ms for the module to enter the Working Mode detection state. The communication mode of the module is determined in the sequence of software configuration, hardware configuration, and automatic detection mode.

1. Detect software configuration
   The detection software configuration means that the communication mode of the module is fixed to UART or I2C according to the configuration result of Set the Device Working Mode in the device control instruction. This setting is not lost when the module is powered on. If the mode is set to I2C, the module enters the I2C mode directly. If the UART mode is configured, the module enters the UART mode directly. The UART baud rate is the baud rate saved in the module. The baud rate can be changed by the Set Baud Rate command in the control class instruction.
2. Detect hardware configuration
   When the working mode of the software configuration is automatic detection mode, the module does not enter a specific communication mode, but further detects the hardware configuration. The detection principle is to determine which communication mode should be used according to the pin level state of the module. J1-6, J1-7, and J1-8 pin level checks take precedence over J1-2 and J1-3. The specific definition of J1 port is shown in Table 4.
   When any pin of J1-6, J1-7 and J1-8 is at low level, the module reads the level state every 1ms for 50 consecutive times, and the level of J1-6, J1-7 and J1-8 does not change, then it enters the I2C mode.
   When any pin of J1-2 and J1-3 is at low power level, the module reads the level state every 1ms for 50 consecutive times, and the J1-2 and J1-3 levels do not change, then it enters the UART working mode.
   Table 4 J1 pins function

   Pin	Symbol	Type	Power on status	Description
   J1-1	/INT	O	High voltage	Interrupt the output pin, open collector; In I2C communication mode, after the command is executed, the pin outputs low level; This pin outputs a low level when a card is detected when the automatic detection command is responded to and the output is interrupted

   J1-2	SCL	O	High voltage	I2C clock input pin, 4.7K pull-up inside the module
   J1-3	SDA	I/O	High voltage	I2C data input/output pin, 4.7K pull-up inside the module
   J1-4	GND	PWR	—	Power negative pin

   J1-7	TXD	O	High voltage	UART transmitter, TTL voltage
   J1-8	CON	I	High voltage	Control pin for RS-485 communication (0: input; 1: output), module automatic control, TTL voltage

   Notes: Square pad is the first pin. 3.3V module J1-5 is connected to 3.3V power supply, and 5V module J1-5 is connected to 5V power supply.

3. Automatic detection mode
   When the software configuration and hardware configuration do not set the module to UART communication mode or I2C communication mode, the module will enter the automatic detection mode. In this mode, both UART and I2C interfaces are in the receiving state. If the module detects an effective baud rate from the UART communication line, the module will use UART communication. If the module receives an SLA from the I2C bus (the factory default SLA is 0xB2), the module communicates using I2C. As long as one of the interfaces receives valid data first, the module will affirm to communicate with the outside world in this way and close the other interface.
   1. In automatic detection mode, the UART needs to receive 0x20 twice before entering the UART communication mode. The first 0x20 is used to calculate the baud rate. The principle is to calculate the baud rate by capturing the two falling edges of 0x20 bytes and obtaining the time between the two falling edges. The second 0x20 is used to determine whether the calculated baud rate is correct. The module will return 0x06 after successfully receiving 0x20 twice. Because this detection mechanism is susceptible to interference, it cannot send data content other than 0x20 to the module before the module calculates the correct baud rate; otherwise, it is easy to calculate the wrong baud rate, resulting in no response to the command sent to the module with the current baud rate.
   2. To ensure that the module can successfully switch to the fixed baud UART communication mode through the automatic detection mode, the recommended operation method is: In addition to the necessary communication interface, an additional I/O port is connected to the EN reset pin of the module, and the module is reset before sending 0x20 twice each time. After the reset, there must be at least 7ms delay before the module can enter the automatic detection mode and receive 0x20 normally.
4. UART communication mode
   By using “Set Baud rate” and “Set device working mode” in the device control class name, the module can be set to use UART communication after power-on. This method belongs to software configuration, and the specific commands are introduced in Chapter 4. Hardware configuration For details about the UART communication mode, see Checking Hardware Configurations. In UART communication mode, after the module is powered on, it reads the serial port Settings (such as module address and baud rate) saved in the module to initialize the communication interface. The host can directly communicate with the module through serial port as long as the baud rate is the same as that of the module.
5. I2C communication mode
   The same as the UART communication mode, you can also use the “Set device working mode” command to set the module to enter the I2C communication mode automatically after power-on. In this mode, the host can directly use the I2C interface to communicate with the module, and the communication address is 0xB2 by default. Of course, you can also use the “Set device working mode” command to change to other values.
   1. For the method of hardware configuration of I2C communication mode, refer to the description in “Detecting Hardware Configuration”. Different from the software configuration, when J1-8 is in high power mode, the module adopts the default address 0xB2 (which can be modified by software), and J1-8 is in low power mode, the module address will be jointly determined by the level of J1-6 and J1-7.
   2. The address byte is 1011 0 (J1-6) (J1-7)x, where x is the read/write bit. For example, if J1-6 and J1-7 are both connected to high levels, the device address is 1011 011x (0xB6).
      Special notes: After the module address is modified in I2C communication mode, the host needs to read the original address and return the command frame before the module can enable the new address, or after modifying the address, the module can also enable the new address after power off and restart.

Typical Applications

UART Interface Applications
The J1.6/J6-2 and J1.7/J6-3 interfaces of the module can be used for UART communication with the host, as long as the host provides a UART interface.

1. Automatic detection mode UART applicationFigure 2. Automatic detection mode: Typical application of UART
   As shown in Figure 2, in this application, the host only needs to provide the UART interface to connect to the module, and the other communication interfaces of the module can be suspended. After the module is powered on, the host command can be executed only after the baud rate is checked. If the baud rate is checked twice, the module determines the communication baud rate and responds to the command 0x06. If you do not perform this step first, the module does not respond to any command sent by the host. Figure 3 shows the flowchart of baud rate setting:Figure 3. Determine the communication baud rate
2. I2C Interface Application
   The J1.1 ~ J1.3 interface of the module can be used for I2C communication with the host, as long as the host provides any three I/O ports.
   Notes: ZLG600S series module J1-2, J1-3 pins are not connected to the inside. in practical application, the user should be connected to the external pull, and the ZLG600A series of these two pins have been pulled up.
   1. Automatic detection mode I2C application
      As shown in Figure 4, in this application, the host only needs to provide an I2C interface and an I/O (for detecting the response of the module) to connect to the module, and other communication interfaces of the module are connected to pull up or hang up (it is recommended to connect pull up). In this mode, the slave IP address of the I2C module is fixed to 0xB2.Figure 4 Typical application of automatic detection of I2C
3. Multi-slave Solution Application
   In order to adapt to the application of I2C multiple slaves, the address inside the module can be set by command, the module address consists of one byte, the lowest is the read and write bit, in line with the I2C address format, so a maximum of 127 slaves can be set (0x00 is unavailable).
   First, the module should be configured through commands, mainly to configure the module working mode, module address and other information. The information will not be lost after a power failure, and the working mode must be re-powered to take effect. Only strictly through the operation of the first two steps, the modules can be connected together to form a multi-slave program application.Figure 5 I2C multi-slave connection diagram
   Figure 5 is a schematic diagram of I2C multi-slave connection, in which the address of the slave can be set to 0x02 ~ 0xFE, there are 127 kinds.
   Before connecting each slave module, run the command to set the working mode to I2C and the module address to the desired address. For details about the command configuration, see “Device Control Command Sets the Working Mode”.
   Note: Under the I2C communication mode, both the new frame format and the old frame format support multi-slave connection, and the description of the two frame formats is described below.
4. DF Control Board Application
   As shown in Figure 6, DF Control Board ZSL-2 is used to be a host of ZLG600A. The J6 interface of the module can be used for RS485 communication with the host, as long as the host provides RS485 ports.Figure 6 ZSL-2 host RS485 interface typical application

Requirement per KDB996369 D03

1. List of applicable FCC rules
   List the FCC rules that are applicable to the modular transmitter. These are the rules that specifically establish the bands of operation, the power, spurious emissions, and operating fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart B) since that is not a condition of a module grant that is extended to a host manufacturer. See also Section 2.10 below concerning the need to notify host manufacturers that further testing is required.3
   Explanation: This module meets the requirements of FCC part 15C(15.225)
2. Summarize the specific operational use conditions
   Describe use conditions that are applicable to the modular transmitter, including for example, any limits on antennas, etc. For example, if point-to-point antennas are used that require a reduction in power or compensation for cable loss, then this information must be in the instructions. If the use condition limitations extend to professional users, then instructions must state that this information also extends to the host manufacturer’s instruction manual. In addition, certain information may also be needed, such as peak gain per frequency band and minimum gain, specifically for master devices in 5 GHz DFS bands. Explanation: The EUT has a Coil Antenna, and the antenna use a permanently attached antenna which is not replaceable.
   This EUT does not have RF shielding; additional evaluation is required for any system using this radio module.
   The antennas as listed in this application must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter procedures The end product should be operated with a minimum of 5mm separation distance from any human body.
3. Limited module procedures
   If a modular transmitter is approved as a “limited module,” then the module manufacturer is responsible for approving the host environment in which the limited module is used. The manufacturer of a limited module must describe, both in the filing and in the installation instructions, the alternative means that the limited module manufacturer uses to verify that the host meets the necessary requirements to satisfy the module’s limiting conditions.

A limited module manufacturer has the flexibility to define its alternative method to address the conditions that limit the initial approval, such as: shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation. The alternative method could include the limited module manufacturer reviews, detailed test data or host designs prior to giving the host manufacturer approval.

This limited module procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained, such that full compliance of the product is always ensured. For additional hosts other than the specific host originally granted with a limited module, a Class II permissive change is required on the module grant to register the additional host as a specific host also approved with the module.

Explanation: The module is a limited module. Any company of the host device that installs this module with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C(15.225) requirement. Various factors should be avoided as far as possible to the wireless signal transmission and reception. Pay attention to the following What time is it:

1. Avoid using metal for the product shell surrounding the Bluetooth. When using a part of the metal shell, try to keep the antenna part of the module away from the metal part.The metal connecting wire or metal screw inside the product should be as far away as possible from the antenna part of the module.
2. The antenna part of the module should be placed against the edge of the carrier board PCB or directly exposed to the carrier board, and it is not allowed to be placed in the middle of the board, There is at least 5mm of free space in the antenna direction, and the carrier board under the antenna is milled out. Copper and wiring are not allowed in a direction parallel to the antenna. 3、It is recommended to use insulating material to isolate the module mounting position on the substrate, for example, put a whole piece of sik screen at this position (Top Over Lay)

Trace antenna designs
For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB Publication 996369 D02 FAQ – Modules for Micro-Strip Antennas and traces. The integration information shall include for the TCB review the integration instructions for the following aspects:
layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.

• a) Information that includes permitted variances (e.g., trace boundary limits, thickness, length, width, shape(s), dielectric constant, and impedance as applicable for each type of antenna);
• b) Each design shall be considered a different type (e.g., antenna length in multiples (s) of frequency, the wavelength, and antenna shape (traces in phase) can affect antenna gain and must be considered);
• c) The parameters shall be provided in a manner permitting host manufacturers to design the printed circuit (PC) board layout;
• d) Appropriate parts by manufacturer and specifications;
• e) Test procedures for design verification; and
• f) Production test procedures for ensuring compliance.

The module grantee shall provide a notice that any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that the host product manufacturer notify the module grantee that they wish to change the antenna trace design. In this case, a Class II permissive change application is required to be filed by the grantee, or the host manufacturer can take responsibility through the change in FCC ID (new application) procedure, followed by a Class II permissive change application. Explanation: Yes, the module with trace antenna designs, and this manual shows the layout of trace design, antenna, connectors, and isolation requirements.

RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RF exposure conditions that permit a host product manufacturer to use the module. Two types of instructions are required for RF exposure information: (1) to the host product manufacturer, to define the application conditions (mobile, portable – xx cm from a person’s body); and (2) additional text needed for the host product manufacturer to provide to end users in their end-product manuals. If RF exposure statements and use conditions are not provided, then the host product manufacturer is required to take responsibility of the module through a change in FCC ID (new application).

Explanation: This module complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.” This module is designed to comply with the FCC statement, FCC ID is: 2AR25ZLG600A-T4.

Antennas
A list of antennas included in the application for certification must be provided in the instructions. For modular transmitters approved as limited modules, all applicable professional installer instructions must be included as part of the information to the host product manufacturer. The antenna list shall also identify the antenna types (monopole, PIFA, dipole, etc., note that, for example, an “omnidirectional antenna” is not considered to be a specific “antenna type”)).

For situations where the host product manufacturer is responsible for an external connector, for example, with an RF pin and antenna trace design, the integration instructions shall inform the installer that a unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. The module manufacturers shall provide a list of acceptable unique connectors.
Explanation: The EUT has a Coil Antenna, and the antenna use a permanently attached antenna which is unique.

Label and compliance information
Grantees are responsible for the continued compliance of their modules to the FCC rules. This includes advising host product manufacturers that they need to provide a physical or e-label stating “Contains FCC ID” with their finished product. See Guidelines for Labeling and User Information for RF Devices – KDB Publication 784748.
Explanation: The host system using this module should have a label in a visible area indicating the following texts: “Contains FCC ID: A3LWCA735M, Contains IC: 31160-ZLG600AT4 ”

Additional guidance for testing host products is given in KDB Publication 996369 D04 Module Integration Guide. Test modes should take into consideration different operational conditions for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product.

The grantee should provide information on how to configure test modes for host product evaluation for different operational conditions for a stand-alone modular transmitter in a host, versus with multiple, simultaneously transmitting modules or other transmitters in a host.
Grantees can increase the utility of their modular transmitters by providing special means, modes, or instructions that simulate or characterize a connection by enabling a transmitter. This can greatly simplify a host manufacturer’s determination that a module as installed in a host complies with FCC requirements.

Explanation: Top band can increase the utility of our modular transmitters by providing instructions that simulate or characterize a connection by enabling a transmitter.

Additional testing, Part 15 Subpart B disclaimer

The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

Explanation: The module without unintentional-radiator digital circuitry, so the module does not require an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC Subpart B.
