Installation Instructions
Indicator meaning
This module has 4 LED indicators:
PWR, RUN, COM and CAN. POWER: System power indicator, red; Steady on: Power is normal: Off: Power is abnormal
RUN: system running indicator; during normal operation, the frequency of on and off is about 1Hz; when CAN is
abnormal, it is always on;
abnormal, it is always on;
COM: RS232/RS485 indicator light, flashes when data is received
CAN: CAN indicator light, flashes when data is received
RS232/485 interface
This module has a total of 1 RS232/485 interface (5. 00mm green terminal lead), of which RS232 uses DB9 female (hole type), the signal definition is shown in the figure It can be connected with standard male serial cable.
CAN interface
The CAN interface is led out by a 5.00mm green terminal, and the interface has a 120 ohm terminal resistance selection function.
as the picture shows Among them, "RS" is the terminal resistance selection. If you connect "RS" and "CAN_L" with a wire, the 120 ohm resistor inside the module is incorporated into the CAN bus: otherwise, the 120 ohm resistor is not connected to the bus.
(According to the ISO 11898 specification, in order to enhance the reliability of CAN-bus communication, the two end points of the CAN-bus bus network usually need to add terminal matching resistors (1209), as shown in the figure below. The size of the terminal matching resistance is determined by the characteristics of the transmission cable The impedance is determined, for example, if the characteristic impedance of the twisted pair is 1202, the two terminals on the bus should also integrate 1202 terminal resistance.)

Module parameter configuration
This module can use "Intelligent Embedded IoT CAN to Serial Configuration Software" to realize the parameter configuration of the module through RS232 or RS485 interface. If you cannot connect to the device due to accidental configuration errors, you can use the "CFG" button to restore the factory parameters (press and hold CFG for 5 seconds, and then release it after the 3 green indicator lights flash simultaneously).
Serial server configuration software
Before configuration, you must know the RS232/485 baud rate of the module that was successfully configured last time. If you forget, you can restore the factory by resetting the module. The factory parameters are 115200, 8, N, 1: The first step is to select the appropriate "serial port number"; The second step is to select the last module's baud rate and other parameters; The third step "open the serial port"; The fourth step "Get device parameters"; After obtaining the parameters successfully, you can modify the parameters. After the modification is completed, click "Save Device Parameters", and then restart the device. The following describes the parameters in the configuration software.
