4-Channel RS232/422/485 Serial Server

Rollover or Touch for Expanded View. Scroll to Zoom.


Compact and simple to configure, the TC3847-1 Serial Server interface card transports four channels of RS-232 or RS-422/RS-485 data over existing Layer 2/Layer 3 Ethernet networks.

The JumboSwitch® series is a TDM over IP/Ethernet based solution designed to emulate time-division multiplexing over packet switched networks (PSN). TDM over IP/Ethernet is a TDM pseudowire (PW) technology making it possible to provision E1, T1, E3, T3, STS-1 and serial data services across PSN's such as IP, MPLS or layer 2 Ethernet Networks.

DIN Rail (DR) version also available for specialized applications view product page
