Built tough for industrial or outdoor environments, like utilities.
Operate in temperature extremes ranging from -40 to +185° F (-40 to +85° C).
Ideal for large polled networks requiring thousands of drops.
Select from three modes via DIP switches, eliminating the need for PC or AT commands. No software code commands necessary.
Feature a 23-msec RTS/CTS delay at 9600 bps in FlashPoll mode and an 8-ms delay at 1800 bps in Bell 202T mode.
Fast poll-response enables you to make more drops per polled link than any other modem.
Adaptive equalizer with DSP technology gives you the fastest speeds even on unconditioned lines.
Provide fast response, short training time, and low throughput delay.
Auto RTS feature enables multidrops for devices with 3-wire data interfaces and no RTS control signal.
Heavy-duty surge protection for their power supply as well as for leased or private lines.
AC and DC models are available, including a rackmount card for the Modem Rack II.


This modem works in extreme conditions and provides super-fast polling times for multidrop applications.


This modem operates at 202T rate and can be switched to 4800 or 9600 to accomodate newer Scada and RTUs, without changing out the entire system.
