3.3.4 RS422 PCIe compact module
The RS422 PCIe compact module contains two electrically isolated Harting ix Industrial
®
type B sockets for
high-speed serial data transfer. Two ix Industrial
®
type B to D-Sub, 9-pin adapter cables are required (order
identifier C9900-K922). The adapter cables are 45 cm long. The signal transfer takes place symmetrically.
The channels are protected by a common overvoltage protection. If an overvoltage occurs at one of the
channels, both channels are switched off.
