1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1070 components to be

free from defects, and will—at our option—repair or replace the product
should it fail within one year from the first date of shipment.

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
product. Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 1070 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 1070 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 1070
does cause interference to radio or television reception, which can be
determined by disconnecting the RS-232 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.

contact Patton Electronics Technical Support at [phone].

2.1 FEATURES

• Data rates from 1.2 to 19.2 Kbps, switch selectable

• Built-in optical isolation & high speed surge protection

• Distances up to 10 miles

• Tristate LED indicators

• Point-to-point or multipoint

• Loopback test modes

• Internal or external clocking

• Hardware and software flow control support

• Externally powered

2.2 DESCRIPTION

The Model 1070 Series synchronous short range modem is

equipped with a virtual wish list of “bells and whistles”: Point-to-point or
multipoint applications are supported. Two separate control signals
may be passed (one each way): RTS and DCD. Data lines are
protected from ground loops and electrically volatile environments by
optical isolation and Silicon Avalanche Diodes. System integrity can be
evaluated using two test modes: local analog loopback and remote
analog loopback. Tri-state LEDs monitor transmit data, receive data
and control signals. Finally, 4-wire connections may be made using
either an RJ-11 jack or terminal blocks—both are included.

In addition, the Model 1070 is perfect for low power RS-232
applications. The new Model 1070 is AC powered and recommended
for low power RS-232 environments. The Model 1070 supports switch
selectable data rates to 19.2 Kbps, and extends RS-232 transmission
distances up to 10 miles over two twisted pair.

The Model 1070 is housed in a sturdy metal case, and comes with
either 115 or 220V external transformers. This is the top-of-the-line in
synchronous short range modems.

3.0 CONFIGURATION

The Model 1070 uses a set of eight external DIP switches that allow
configuration to a wide range of synchronous applications. Because all
eight switches are in one externally accessible DIP package, there is no
need to open the Model 1070's case for configuration. The switches allow
you to control line contention, clocking methods, RTS/CTS delay and data
rates. Figures 1 and 2 (below) and Table 1 (opposite page) summarize
the switch locations, positions and functions.

3.1 DETAILED SWITCH SETTINGS

This section provides detailed information about the function of
each DIP switch and lists all possible settings. Use this section as
configuration guide for applications where the Model 1070's default
would not provide correct results.

3.1.1 DATA RATE

Switches 1 thru 3 are set in combination to allow the Model 1070 to
be used at data rates from 1200 bps up to 19,200 bps.
