SW485 - RS485 splitter / extender for up to 9 channels
PA-SW485 is used to link RS485 signals. Up to nine RS485 signals can be connected in a star topology. All channels are equal. When data is received on one channel, the same data is transmitted to other channels. Each line has its own detachable terminal connection.
PA-SW485 has the RS485 connections listed as RxTx + and RxTx-. Remember to connect, for example, RxTx + to other devices' RxTx + and vice-verse.
RxTx+ can be referred to as "A" on other units.
RxTx- can be referred to as "B" on other units.
