The CI-134 series ISA boards come with 4 independent RS-422/485
serial ports for connecting data acquisition equipment and other serial
devices to a PC. Connect your devices over longer distances—up
to 1.2 km (4000 ft)—and ensure greater reliability in industrial
environments with on-board surge protection and optical isolation
(available with some models). Enjoy greater versatility by using
point-to-point full duplex connections, or set up a half duplex RS-485
multi-drop network.
