OVERVIEW
SGCAN300 CANBUS RELAY MODULE can realize the mutual conversion between MSC1 and optical fiber, MSC1 and MSC2, RS485 and optical fiber. Using the module can increase the communication distance of MSC or RS485.
PERFORMANCE AND CHARACTERISTICS
- With conversion function of MSC1 and optical fiber, using a pair of modules can realize long distance MSC communication;
- With conversion function of RS485 and optical fiber, using a pair of modules can realize long distance RS485 communication;
- With data conversion function of MSC1 and MSC2, using a single module can increase the MSC communication distance;
- With one digital input, which can control signal conversion enabling;
- The effective type of input port can be set by the dial switch of the module;
- The baud rates of MSC1 and MSC2 can be set by the dial switch of the module;
- The baud rate of RS485 can be set by the dial switch of the module.

| 6 | RS485 Baud Rate 0：9600bps 1：19200bps |
| 7 | Optical Fiber Mode 0: Optical fiber is connected with CAN1.
(Input port should be effective) 1: Optical fiber is connected with RS485. (Input port should be effective) |
| 8 | Test Mode 1: Lamp test function. Each dial switch corresponds to an LED
indicator light, light on when is 1. |
NOTE: “ON” of dial switch is 1 and “Non-ON” is 0. There need power on again when baud rate changed.
MUTUAL CONVERSION OF MSC1 AND OPTICAL FIBER
When the digital input is effective, the dial switch 7 is placed to Non-ON, at which time the MS1 is connected with the optical fiber. The baud rate can be selected by dial switch 2 and 3. The other SGCAN300 module will go to the same setup. Connecting the optical fiber communication lines of two SGCAN300 modules, then the MSC1 interface of the two modules can be converted through the optical fiber.
MUTUAL CONVERSION OF RS485 AND OPTICAL FIBER
Place the dial switch 7 to ON, then the RS485 is connected with the optical fiber. The baud rate can be selected by dial switch 6. The other SGCAN300 module will go to the same setup. Connecting the optical fiber communication lines of two SGCAN300 modules, then the RS485 interface of the two muddles can be converted through the fiber.
MUTUAL CONVERSION OF MSC1 AND MSC2
When the digital input is effective, then the MSC1 is connected with the MSC2. The baud rate can be selected by dial switch 2,3,4,5, then the interfaces of MSC1 and MSC2 are converted

TOUBLESHOOTING
Table 7 –Troubleshooting
| Symptoms | Possible Solutions |
|
Communication failure of MSC1 and MSC1 of the other module |
1.Check communication line and communication terminal resistance; 2.Check digital input status and effective type;
3. Check whether the communication baud rate is consistent with the controller; 4. Check whether the dial switch 7 is Non-ON; 5. Observe the communication indicator light to judge the communication error. |
|
Communication failure of RS485 and RS485 of other module |
1.Check communication line and communication terminal resistance; 2.Check whether the communication baud rate is consistent with the controller;
3. Check whether the dial switch 7 is ON; 4. Observe the communication indicator light to judge the communication error. |
|
Communication failure of MSC1 and MSC2 |
1. Check communication line and communication terminal resistance;
2. Check digital input status and effective type; 3. Check whether the communication baud rate is consistent with the controller; 4.Observe the communication indicator light to judge the communication error. |
| There is no response for power
on and all lights are off |
Check dial switch 8 and it should be Non-ON. |
