This warranty is limited to defects in workmanship or materials, and
does not cover customer damage, abuse, or unauthorized modification.
If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings, and incidental or
consequential damages arising from the use of or inability to use this

1.1 RADIO AND TV INTERFERENCE

The Model 1008 generates and uses radio frequency energy, and if
not installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and
television reception. The Model 1008 has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that
interference will not occur in a particular installation. If the Model 1008
does cause interference to radio or television reception, which can be
determined by disconnecting the EIA/TIA-574 interface, the user is
encouraged to try to correct the interference by one or more of the
following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna, and/or plugging the
receiving equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Technical
Support.

2.2 DESCRIPTION

The Model 1008 High Speed, Multipoint, DB-9 Short Range

Modem provides exceptional versatility in an ultra-miniature package.

Requiring no AC power or batteries for operation, the Model 1008
supports asynchronous EIA/TIA-574 data rates to 115.2 Kbps over one
or two unconditioned twisted pair. Distances up to 15.0 miles are
attainable at lower data rates (1.2 Kbps, 19 AWG twisted pair).

The Model 1008 can handle up to 50 terminal drops in a multipoint

polling environment. For RS-485 and serial printer applications
requiring hardware handshaking, the Model 1008 passes one control
signal in each direction. The Model 1008 may be configured for high or
low impedance, carrier may be set to “constantly on” or “controlled by
RTS”, and the unit can operate with or without “echo”. RTS/CTS delay
may be set for “no delay” or 8 mS.

Options for twisted pair connection include terminal blocks with

strain relief, RJ-11, RJ-45 and dual modular connectors for daisy
chaining. Silicon Avalanche Diodes provide 600 watts per wire of
protection against harmful data line transient surges.

3.0 CONFIGURATION

The Model 1008 is configured using two PC board mounted

4-position DIP switches. This section shows how to access the DIP
switches, provides an overview of the factory default settings, and
describes all possible configuration options. For instructions on how to
configure the Model 1008 for specific applications, refer to Section 5.0.

3.1 ACCESSING THE DIP SWITCHES

The Model 1008 has main PC board and a daughter board. DIP
switch S1 is located on the underside of the main PC board (see Figure
1, below). DIP switch S2 is located on the top of the daughter board
(see Figure 2, below).

To access the Model 1008’s internal PC boards, insert a small flat­blade screwdriver between the connector and the lip of the case and
twist gently as shown in Figure 3 (below).

Both DIP switch S1 and S2 are marked with individual switch
numbers 1 thru 4. Use these numbers, as well as the “ON” designation
to orient the switch properly (see Figure 4, below). Use a small screw
driver or similar instrument to set each individual switch.
