3. converter in use
3.1 USB에 연결
When driver and software have been installed, connect the converter to the USB interface, a new USBCAN device named “GC – Tech USBCAN Device” can be found in the PC Device manager.
3.2 CAN에 연결
GCAN-206 converter connect to CAN-Bus as chapter 2.3, CAN_H to CAN_H, CAN_L to CAN_L.
The CAN bus network adopts topological structure, only the two furthest terminal need to connect 120Ω terminal resistance between CAN_H and CAN_L. For branch connection, its length should not be more than 3m. CAN-bus nodes connection as shown in figure 3.1

Note: the CAN-bus cable can use ordinary twisted-pair cable, shielded twisted-pair cable. Theory of the maximum communication distance depends on the bus baud rate, Their relationship as shown in the Table 3.1.

3.3 CAN-Bus 단자 저항
통신 안정성을 향상시키고 CAN 버스 터미널 반사를 제거하기 위해 가장 먼 두 터미널은 그림 3.2와 같이 CAN_H와 CAN_L 사이에 터미널 저항을 연결해야 합니다. 단자 저항 값은 케이블의 특성 임피던스에 의해 결정됩니다. 예를 들어, 특성 임피던스는 120Ω입니다.

NOTE: GCAN-206 doesn’t have integrated 120Ω terminal resistance, and need the customer to add it.
3.4 시스템 LED
GCAN-206 converter with one SYS indicator to indicate the converter status. One DAT indicator to indicate data transmission. More functions are shown in table 3.2 and 3.3.

When GCAN-206 converter power on, SYS light, indicates the converter has power supply, the system is initialized. Otherwise, a system power failure or system errors has exist. When CAN-Bus1 or CAN-Bus2 data transceiver, DAT will blinking.
