i have a device which works on RS 422 four wire , but does not have any identity of its own ( means there is no option for putting any address ). i need to connect 88 devices on a single system, how can i do this ?
Hello Shubh, does your device support RS485? RS-422 - Wikipedia [quote]RS-422 cannot implement a true multi-point communications network such as with EIA-485 since there can be only one driver on each pair of wires. However one driver can fan-out to up to ten receivers.[/quote]
