IoTize TapNPass Nomad NFC-BLE Adapter for Modbus Instruction Manual

Use an off-the-shelf USB (A) cord when connecting to a target’s USB connecter. This cord is not provided with TapNPass.
Note: For Modbus connections, plug the provided Modbus adapter into the TapNPass RJ45 port and use an off-the-shelf network cord to connect to the target. The network cord is not provided with TapNPass.

Note:
A placement for a battery LED ()may be visible on the front of TapNPass
Fix products. This LED is only implemented for the Nomad versions to indicate the charge state of the battery. It is not used on the Fix products.

Power Consumption Characteristics

TapNPass is a low power-consumption device (typically 200 mW).
However, overall consumption depends on the type of connection to the target system. For example, a USB device connected on the USB (A) port may consume up to 2.5W (5V – 500mA). The following are examples of measured consumption with a 5V source:

RS-232: 35mA
RS-485: 45mA

USB: 110mA (with an FTDI or CP2 l Ox connected cable)

Power Supply

Connect an external power supply on the provided connector. The supported voltage range is 10V to 30V.
It is recommended to use a power source of 5W ( 12v/ 400mA or 24V /200mA) and connection wires of 2.5mm?.
To connect the power supply:

Insert the provided terminal block plug (Molex 039530-0002)into the power supply connector on the back of the TapNPass.
Insert the two wires from the power source
Note: The polarity does not matter. The voltage input port is equipped with a bridge rectifier.

Tighten the 2 screws to secure the wires in place

Connect to a Target

Connect TapNPass to the target system. Available connections are:

Connection Type	Cord	TapNPass Connector	Target Connector
Serial RS-232	RS-232 cord’	RJ45	DB9
Serial RS485	RS-485 cord’	RJ45	DB9
Serial USB (host)	US8 (A)	US8 (A)	USB
Serial w/Modbus-RTU	Modbus adapter + network cable	RJ45	RJ45

Notes:

Provided with TapNPass.
Not provided. Use any off-the-shelf cord of this type.

Connect to your Mobile

TapNPass connects to Android and iOS mobiles via Bluetooth low energy (BLE) and Near Field Communication (NFC).
It is pre-configured for serial or Modbus communication with target systems using the Tap Toolbox opp.
Note: TapNPass can also be reconfigured. See section 4.

Get Tap Toolbox

Go to Google Play Store or to the App Store. Download and install loTize Tap Toolbox.
Note, For Android mobiles (with NFC) and iOS (iPhone XR/XS). Activate NFC and a data connection, then hold the mobile to the NFC indicator on TapNPass. Tap Toolbox will be proposed automatically for installation.

Connect to mobile to TapNPass

Activate the mobile’s Bluetooth and data connections.
Press TapNPass’s Power button to start its Bluetooth.

Launch Tap Toolbox and select Scan to find your TapNPass.
Select your TapNPass from the list of Bluetooth devices.
After you are connected, Tap Toolbox provides the utilities:
• Terminal: sends/receives characters via RS-232, RS-485, or USB interfaces.
• Modbus: drive one or more Modbus (slave) devices. Only Modbus-RTU is supported.

Modbus utility

Define a register to monitor

Click in the Registers area, then enter:

Slave id (8-bit value)
Register address (16-bit value)
Type (default is ‘holding register’)
Format: registers are 16-bit. They are truncated for 8-bit values. 32-bit values use 2 consecutive registers.
Length: the number of consecutive registers to be accessed
Display mode (HEX or DEC)

Click on Save and then Read.
The register is listed in the Register display and the values are in the Register definition field.

Save a register for later use

Click on the register in the Registers area
Swipe to the left
Click on the Save button

This saves the register and related settings to a list of registers.

Terminal utility

Selecting Terminal opens this utility for sending text commands and visualizing responses.

Input Settings

Click in the Terminal display. These settings are specific to the Terminal utility.

UART settings

Click the menu icon on the left and select Settings.
These settings are common to Terminal and Modbus utilities.

Advanced Configuration

Your TapNPass can be configured to:

Require login for access to features or data
Open an HMI opp that you created for your systems or your user
The loTize Studio configuration environment, detailed documentation, application notes, and opp development resources are available online at:
http://docs.iotize.com/Gettingstarted/TapNPass/

Troubleshooting

App won’t display any register values
If Tap Toolbox Modbus utility does not display any values from your Modbus slave, verify that:

The connection cord is plugged into TapNPass and the target.
Connection cord pinout is correct for your target. The problem may be caused by inverted DO and Dl signals.
To comply with the Modbus specification, TapNPass uses an RJ45-RJ45 cord with a specific pin specification. Try this cord first.
If the provided cord does not work, you can also try an Ethernet cord with the standard pinout.
If neither cord works, you will have to verify the pin connections on the target and may have to adapt a cord to your target’s pinout.
The UART settings are appropriate for the target.

The slave address is correct for the target.
You have access to the Modbus features in the current TapNPass configuration. For a new TapNPass, the initial configuration allows access without login for Modbus and Terminal features. If the configuration has been changed, you will have to obtain the login from the configuration project or the user who configure the TapNPass.
