Page 8: 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). - Page 9 485 Bus1, Err2 the RS-485 Bus2, and so on. The SER-4485-SI-M power input is designed with a diode bridge circuit. You don’t need to care the input DC power polarity, and you can also use an AC to AC 9V ~ 48V power adapter for SER-4485-SI-M.
