1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1045RC 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 1045RC 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 1045RC 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
1045RC does cause interference to radio or television reception, which
can be determined by turning the power off or removing the card, 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). In the event the user
detects intermittent or continuous product malfunction due to nearby
high power transmitting radio frequency equipment, the user is strongly
advised to take the following steps: use only data cables with an
external outer shield bonded to a metal or metalized connector; and,
configure the rear card as shown in section 3.2.1 of this manual.

1.3 SERVICE

All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container.This number may be obtained from Patton Electronics
Technical Support at: [phone]; http://www.patton.com; or,
[e-mail].

Packages received without an RMA number

will not be accepted.

Patton Electronics' technical staff is also available to answer any
questions that might arise concerning the installation or use of your
Model 1045RC. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

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 1045RC high speed SRM supports sync. and async.

data rates of 32, 56 and 64 Kbps, and distances to 6 miles. Sync.
transmit clock options are internal, external and receive loopback clock.

The Model 1045RC incorporates two V.54 test modes: local analog
loop and remote digital loop. These can be activated from the front
panel, or via the RS-232 or V.35 interface. Additionally, a built-in V.52
BER test generator can output 511 and 511E bit patterns. Seven easy­to-read LED indicators monitor power, transmit data, receive data, RTS,
carrier detect, test mode and test pattern. For protection against
ground loops and transient surges, the Model 1045 incorporates both
isolation transformers and Silicon Avalanche Diode surge suppressors.

The Model 1045RC is designed to mount in Patton’s 2U high 19”
rack chassis. This 16-card chassis has a switchable 120/240 VAC
power supply (optional 48 VDC) and mounts cards in a mid-plane
architecture: The front card can be plugged into different rear cards.
This means that the Model 1045RC card can have several interface
options and can be switched with other Patton short haul cards.

This section describes the location and orientation of the Model
1045RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.

The Model 1045RC uses a combination of DIP switches and
jumpers that allow configuration to an extremely wide range of
applications. Designed around a mid-plane architecture, the Model
1045RC incorporates both front and rear cards. Configuration of both
may be necessary. The switches/jumpers are accessible when the
cards are slid out of the rack chassis. Once configured, the Model
1045RC is designed to operate transparently, without need for frequent
re-configuration: just set it and forget it!

3.1 FRONT CARD CONFIGURATION

The Model 1045RC front card has two sets of eight switches (S1 &
S2), one jumper (JP3), and a reversible daughter board, which are all
mounted on the PC board (Figure 1, below). These configuration
devices allow you to select data rates, clocking methods, V.52 & V.54
tests, word lengths, extended signaling rates, async. or sync. mode,
2- or 4-wire operation, and RS-232 or V.35 terminal interface. The
ON/OFF orientation of the DIP switches is shown in figure 2 (above).
