Connection

A. We suggest using chain connection or bus connection. The cable length

keeps in 7 meters if you use bus connection.

B. Regarding 120 Ω resistances: once the communication distance is more than

300 meters you have to add a terminal resistance in the farthest terminal of

485 cables. When the device quantity is less than 22 pieces, you could not add

the resistance. Just change the jumper cap on the decoder board from jump pin

1 and 2 to pin 2 and 3 to enhance the resistance.

C. Max 32 device can be connected without control code distributor. If you

need more devices, an extra distributor will be needed.

D. Farthest distance of RS485 communication cable is 1800 meters, Due to

different baud rate, transmission distance will be different. For longer

transmission distances, an extra control code distributor or amplifier will be

needed.

E. In order to avoid the interference, please keep the RS485 cable away from

high voltage cable and separate from other power wire.
