This RS-422/485 Repeater is an efficient solution for applying advantages of RS422/485 to legacy RS422/485 devices. The repeater operates with no extra software installation. With simple DIP switch toggling, RS422 or RS485 can be selected. Also, the product is fully compatible with serial COM port in PC.

Using 4-wire RS485
4-wire RS485 Networking is the same as RS422 Multi-Drop Networking. RS422 device is used as master and RS485 device is used as slave in 4-Wire RS485 bus. Although RS422 and RS485 have different electrical standards, most manufacturers make ICs that uses both RS422 and RS485 interface. Therefore, RS422 Multi-Drop and 4-Wire RS485 can be considered equal.

However, there can be difference in software that controls them. Since this RS-422/485 Repeater can operate regardless of the application software, it is ok to use without any trouble. In this case, set RS422 Multi-Drop mode.
