The FC−24ETH is a two-directional RS−232/RS−485 to Ethernet
control signal converter and allows you to control four
RS−232 controllable units via Ethernet or LAN. It can also
control one RS−485 and three RS−232 instead of four RS-232.
The unit features USB port for upgradable firmware. You can
rackmount two units side−by−side in a 1U rack space together
with the optional RK−T2B universal rack adapter.
