Description
The Auto485 adapter is a general purpose, auto-turnaround RS232-toRS485 converter that can be used to convert any standard RS232C port into a two-wire RS485 port and vice versa.
When used with TRi’s programmable controllers, it greatly expands the PLC’s serial I/O capabilities by allowing multiple PLCs to be linked to a single PC for programming, file services or internet connectivity. It can also be used to convert the PLC’s RS485 into an additional RS232 port for
connections to third party RS232 devices such as HMI, frequency inverters, barcode scanners, smart card readers, external modems etc.
