New Modem Has Extra Controls

Patton Electronics is pleased to announce the Model 1018 SLIP Short Range Modem. The Model 1018 was designed for RS-232 systems running SLIP (Serial Line Internet Protocol) and PPP (Point-To-Point Protocol). So the modem can be used for campus connection of workstations to Internet communications systems (see other column). However the unit is ideal for any application requiring additional flow control lines.

This unit supports the same two in-band flow control signals that you see on the Model 1004 and Model 1012A. If you are not familiar with these other models, "in-band" just means the control is accomplished via the line carrier and it interrupts the flow of data. In addition the Model 1018 also supports two out-of-band, channel independent, flow control signals (one in each direction) On the miniature unit, the out-of-band flow control is set-up for RTS (Pin 4) to control CTS (Pin 5) and vice versa, but can be configured on the rack card unit to be present on a variety of pins (Rack cards are expected to be announced within a few weeks). The in-band flow control signals are set up on DTR (Pin 20 ) and CD (Pin 8).

The Model 1018 operates asynchronously and supports data rates from 1200 bps to 57,600 bps operation at distances of 2.5 miles, regardless of the data rate!

With Full V.54 diagnostics and V.52 compliant BER tests, the unit has all the sophisticated diagnostic tools expected. The units also provides four LED indicators for TD, RD, Test and BERT functions. Coupling to the analog interface are isolation transformers ensuring a high level of immunity to line noise and ground loops. The modem utilizes the latest in low power, surface mount, ASIC technology to address a relevant new market for short range modems.

The Model 1018 retails for $325 and we are shipping units now!
