Introdución

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.

Enabling the DC +5V or DC +12V Power for External Devices

Outside the unit, there is a 3-pin DIP switch (SW) which are settings used for enabling 5V or 12V (500mA max.) power for external devices.

SW		FUNCIÓN
PIN 1	ON	Enable DB9 pin 1 to provide 5V or 12V power for external devices
PIN 1	DESACTIVADO	Disable the 5V or 12V power on pin 1

Resistores de terminación

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.

DESCRICIÓN DA FUNCIÓN

Indicadores 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.

Conxunto de comandos 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.

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

Comando	Resposta	Función
S6[CR]	[CR]	Set the bitrate of the CG-1P232CAN adapter to 500 Kbps
O[CR]	[CR]	Open CAN channel
t0023112233[CR]	z[CR]	Send CAN message (ID = 002h, DLC = 3, Data = 11 22 33)
C[CR]	[CR]	Close the CAN channel

Lista de comandos

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.

Comando	Resposta	Función
H[CR]	[CR]	List all supported commands
h[CR]	[CR]
?[CR]	z[CR]

ExampLe: H[CR]

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.

Comando	Resposta	Función
O[CR]	[CR]	Open the channel in Normal mode
L[CR]	[CR]	Open the channel in Listen Only mode
Y[CR]	[CR]	Open the channel in Loopback mode

The CAN bus channel will be closed with the command C[CR]. The command can only be used if the CAN bus channel is open.

Comando	Resposta	Función
C[CR]	[CR]	Close the CAN channel if it is open

Setting CAN Bitrate (Standard)

The CAN bus bitrate can be set with the command SX[CR]. The command can only be used if the CAN bus channel is closed.
