2.2 DESCRIPTION
The Model 1009 Asynchronous Short Range Modem lets two
asynchronous RS-232 devices with DB-9 connectors communicate at
distances up to 17 miles. Operating full duplex over two unconditioned
twisted pair, the Model 1009 supports data rates from 300 to 19,200
bps. The Model 1009 draws all necessary operating power from the
RS-232 interface, and requires no AC power or batteries.
The Model 1009 has been designed to connect directly to IBM AT
compatibles, Unisys 6000/7000 Series, NCR "Towers" and other RS-
232 machines with DB-9 serial ports. Its ultra-miniature size (2.50" x
1.20" x 0.75") allows the Model 1009 to fit in very tight installation
spaces. Twisted pair connection can be made using RJ-11, RJ-45 or
terminal blocks with strain relief. For added flexibility, the Model 1009 is
compatible with Patton's Model 1000 and 1015 Short Hauls.
The Model 1009S uses the latest in bi-directional, clamping
transient suppressors to guard itself and connected equipment against
data line transients. For surge handling capability, the Model 1009S is
compliant with IEC 801.5, Level 2, 1kV. The Model 1009S is
recommended for environments prone to lightning storms, static
discharge and other forms of EMR.

3.0 INSTALLATION
The Model 1009 is easy to install and requires no pre-
configuration. This section tells you how to properly connect the Model
1009 to the twisted pair and RS-232 interfaces, and how to operate the
Model 1009.
3.1 CONNECTION TO THE TWISTED PAIR INTERFACE
The Model 1009 operates full duplex in point-to-point
environments. It passes data as well as X-ON/X-OFF (software)
handshaking signals. There are two essential requirements for
installing the Model 1009:
1. These units work in pairs . Therefore, you must have one Model
1009 at each end of a two twisted pair interface.
2. To function properly, the Model 1009 needs two twisted pairs of
metallic wire. These pairs must be unconditioned , dry, metallic wire,
between 19 and 26 AWG (the higher number gauges may limit distance
somewhat). Standard dial-up telephone circuits, or leased circuits that
run through signal equalization equipment, are not acceptable .
For your convenience, the Model 1009 is available with three
different twisted pair interfaces: RJ-11 jack, RJ-45 jack, and terminal
blocks with strain relief.
3.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45
The RJ-11 and RJ-45 connectors on the Model 1009's twisted pair
interface are pre-wired for a standard TELCO wiring environment. The
signal/pin relationships are shown below:
