Giới thiệu

Thank you for purchasing Coolgear’s 1 Port Serial RS232 to CAN Bus Adapter. A Controller Area Network (CAN) is a high-integrity asynchronous serial bus system for networking intelligent devices. It is often used in automotive and industrial systems.
The CG-1P232CAN is designed to provide a fast, simple way to communicate with CAN bus devices. Connected to a serial port on your computer, the CG-1P232CAN instantly adds an industrial CAN bus channel to your host system.

The CG-1P232CAN provides a cost-effective solution for customers to enable communication with CAN bus devices.
The solution designed by the ARM Cortex-M0 32-bit microcontroller makes it very ﬂexible in handling small bursts of CAN frames at a high speed.

Plugging the CG-1P232CAN into the serial port, the CG-1P232CAN adapter provides instant connectivity to CAN bus devices.
The CG-1P232CAN provides an industrial solution for applications of CAN bus multi-drop communications over short and long distances.

The CG-1P232CAN provides DC +5V/+12V 500mA power for external devices and is powered from an external DC 12V power supply.

Điện trở kết thúc

The serial-to-CAN adapter does not provide CAN bus termination resistors. A CAN bus network requires 120Ω termination resistors at each end.

Generally, this must be done in the cabling. Since this depends on the installation of connections, please check your CAN bus cable speciﬁcation for proper impedance matching.

MÔ TẢ CHỨC NĂNG

Đèn báo LED

The CG-1P232CANadapter has three LEDs (red LED, green LED, yellow LED) to indicate power and CAN bus statuses.

The red LED indicates CG-1P232CAN adapter power; the green LED indicates CAN bus data activity, and the yellow LED indicates a CAN bus error.
The following are the deﬁnition of different LED combinations.

A: Power up (device initialized)

After CG-1P232CAN powers up (device initialized), the red LED turns on and the green & yellow LEDs ﬂash four times to indicate that the CG-1P232CANadapter has been initialized.

B: CAN bus channel open/close

When CAN bus channel opens, the green LED will turn on to indicate that the CAN bus channel is open; When CAN bus channel closes, the green LED will turn off to indicate that the CAN bus channel is closed.

C: CAN Bus Data Activity

When a CAN data frame is sent or received, the green LED ﬂashes continuously to indicate CAN bus data I/O activity.

D: CAN Bus Error

When an error occurs on the CAN bus, the yellow LED ﬂashes continuously to indicate a CAN bus error.

Bộ lệnh ASCII

With simple ASCII commands the CG-1P232CAN adapter can be controlled over the serial port. Users can send/receive commands from any simple serial terminal program.

Examplê: Set bitrate to 500 Kbps, open CAN channel, send CAN frame (ID = 002h, DLC = 3, Data = 11 22 33), close CAN.

C[CR]	[CR]	Close the CAN channel

Danh sách lệnh

The commands are line-based and terminated with the newline character CR (0xD). On error, the response will be 0x7 (BELL).

The “help” command (‘H’, ‘h’, or ‘?’) will list supported commands.

Opening the CAN Bus Channel

The CAN bus channel will be opened with the command O[CR], L[CR], or Y[CR].
The command O[CR] will open the CAN bus channel in normal operation mode, and the command L[CR] will open the CAN bus channel in listen-only mode, in which no bus interaction will be done from the controller.

The command Y[CR] will open the CAN bus channel in a loop-back mode, in which the CG-1P232CAN adapter will also receive the frames that it sends. Before you use one of the commands, you should set a bitrate with the commands S or s.
