Patton electronic 1018RC - Manual (Page 3)

3.0 CONFIGURATION
This section describes the location and orientation of the Model
1018RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.
The Model 1018RC 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
1018RC 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
1018RC is designed to operate transparently, without need for frequent
re-configuration: just set it and forget it!
3.1 FUNCTION CARD CONFIGURATION
The Model 1018RC front card has two sets of eight switches (S1 &
S2), which are mounted on the PC board (Figure 1, below). These
configuration switches allow you to configure the Model 1018RC for a
wide range of applications. The ON/OFF orientation of the DIP
switches is shown in figure 2 (below). Jumpers JP1 through JP4 are
primarily used for factory configuration, and should be left in their
default positions.

2.2 DESCRIPTION
The Patton Model 1018RC short range modem rack card passes
two “session” control signals (DTR/DCD), as well as two channel-
independent flow control signals (RTS/CTS). This capability makes the
Model 1018 suitable for SLIP (Serial Line Internet Protocol) and PPP
(Point-to-Point Protocol) applications, as well as other serial
applications requiring extra controls.
The Model 1018RC supports asynchronous data rates from 1.2 to
57.6 Kbps, and distances to 2.4 miles. The Model 1018RC
incorporates two V.54 test modes (local analog loop and remote digital
loop), which can be activated from the front panel via the RS-232
interface. Additionally, a built-in V.52 BER test generator can output
511 and 511E bit patterns. Five easy-to-read LED indicators monitor
power, transmit data, carrier detect, test mode and test pattern. For
protection against ground loops and transient surges, the Model
1018RC incorporates both isolation transformers and Silicon Avalanche
Diode surge suppressors.
The Model 1018RC 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 1018RC card can have several interface
options and can be switched with other Patton short haul cards.
