2.2 DESCRIPTION
The Model 1000 Asynchronous Short Range Modem uses the
latest surface mount technology to attain high quality short range
modem performance in a low profile package. The unit operates full
duplex at data rates to 19.2 Kbps over 2 twisted pair. Requiring no AC
power or batteries, the Model 1000 supports distances to 17 miles
(27.2km).
With an externally accessible DCE/DTE switch, the Model 1000
allows easy connection to any device without opening the unit. Three
enclosure options allow terminations to be via RJ-11, RJ-45 or terminal
blocks. A unique strain relief prevents thin twisted pairs from breaking
or pulling loose.
The Model 1000S is a surge protected version of the Model 1000
that uses the latest in bi-directional, clamping, transient suppressors to
protect itself and connected equipment against harmful transient
discharges. For surge handling capability, the Model 1000S is
compliant with IEC 801.5 level 2, 1kV.

3.0 CONFIGURATION
The Model 1000 is designed to be easy to use. There are no
internal jumpers or configuration switches to set, so there is no need to
open the case to configure the unit (you may need to open the case for
wire connection—refer to section 4.0). The only configuration
necessary for operation is proper setting of the external DCE/DTE
switch.
Figure 1, below, shows the location of the DCE/DTE switch on the
PC board, as well as the location of the terminal block and surge
suppressors ("S" model only).
3.1 SETTING THE DCE/DTE SWITCH
For your convenience, the Model 1000 has an externally
accessible DCE/DTE switch (see diagram below). If the device
connected to the Model 1000 is a modem or multiplexer (or is wired like
one), set the switch to "DTE". This setting causes the Model 1000 to
behave like Data Terminal Equipment and transmit data on pin 2.
If the device connected to the Model 1000 is a PC, terminal or host
computer (or is wired like one), set the switch to "DCE". This setting
causes the Model 1000 to behave like Data Communications
Equipment and transmit data on pin 3
(Default Setting is “DCE”).
