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 easy-
to-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.

3.0 CONFIGURATION
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).
