INTRODUCTION |
|
|
 |
|
The RPT-485_422-2 is a RS-485/RS-422
repeater/converter, which can be used to extend the RS-485
or RS-422 distance to up to 4000 ft (1.2km). It
can also be used to convert a two-wire RS-485 signal into a
four-wire RS-422 signal, and vice versa.
This
product features data direction auto-turnaround. Therefore,
no flow control is required.
