Features



RS422 or RS485 operation



2-wire or 4-wire in operation  

in RS-485 mode



Full/Half-duplex transmission 

at speeds up to 1.25 Mb/s

Link a remote terminal to a host
computer: Connect multiple de-
vices, such as security scanners,
POS devices, remote terminals and
building access/alarming systems
to a host computer. Ideal for cam-
pus or business environments
where remote devices can be net-
worked in either a point-to-point or
point to multi-point configuration.

Transition Networks serial RS-
422/485 to Fiber NID allows you to
extend the distance between serial
connections with the use of fiber
optic cable. This full-featured NID
operates in 2-wire mode for RS-
422 and either 2-wire or 4-wire
mode for RS-485 and supports full
or half-duplex data transmission at
speeds up to 1.25 Mb/s.
