Function and Application
|
This converter allows to interface any device using RS232 serial link to RS485/RS422
|
|
|
link. The RS485 specification allows to network up to 32 Notes on the same lines, at speeds up to 10
|
|
|
Mbps to distances of 4,000 feet (1200 meters). RS485/RS422 links are much used in industrial process
|
|
|
control where reliability is important.
