Overview
Changing line signals is no longer a problem. StarTech.com’s IC485S / GB / EU
converts RS-232 serial interfaces to RS-485/422 serial interfaces. This 2 in 1 converter
converts RS232C to either the RS 485 or RS 422 interface. Other features include DCE/
DTE selectable modes, point to point multidrop configuration and the ability to monitor
RS 485/422 signals.
The IC485S / GB / EU can be powered from the following two ways:
1. DC 9V, 200mA power adapter
2. The pin #9 of the RS-232 connector
The following is a figure of the IC485S / GB / EU:
