Topic: Multiplexing RS232 RFID Writer (Read 281 times) previous topic - next topic


Hi my name is Mikernick and I am new to Arduino and the forum.

I need a device that allows me to write data from a single RS232 port to 1 of 4 RFID writers. this will be done in sequence.

That is my program enters a subroutine and writes data with a date time stamp to RFID writer 1. it the  re-enters the subroutine and writes similar data to RFID writer 2.

This sequence is repeated 4 times.

Can anybody assist with a device I can use that will programmtically switch this output.

Thanks. :)
