Installation

•

For converting RS-232 to RS-485, connect the data cable to TxD, RxD and GND

signals in upstream ports of SER-4485-SI-M. You need to connect the TxD pin to an

external RS-232 TxD signal (pin3 of DB9), the RxD pin to an external RS-232 RxD

signal (pin2 of DB9) and the GND pin to external RS-232 GND pin (pin5 of DB9).

•

For converting RS-485 to RS-485 hub, connect the data cable to the Data+, Data-

in upstream ports of SER-4485-SI-M. You need to connect the Data+ pin to the

Data+ signal of an external RS-485 bus and the Data- pin to the Data- signal of an

external RS-485 bus.

Connect the data cable to the Data+1~4, Data-1~4 in downstream ports of SER-

4485-SI-M for four RS-485 bus or devices.
