1.0 WARRANTY INFORMATION
Patton Electronics warrants all Model 1018RC 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 1018RC 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 1018RC 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
1018RC 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 nonwarranty 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

2.2 DESCRIPTION
The Patton Model 1018RC short range modem rack card passes
two “session” control signals (DTR/DCD), as well as two channelindependent 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.

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.

RTS/CTS Delay. Descriptions of all possible S1 switch settings,
including the Patton factory default settings, are found on on pages 4
and 5.

S1-3 through S1-6: Not Used
S1-7 and S1-8: RTS/CTS Delay
The combined settings for switches S1-7 and S1-8 determine the
amount of delay between the time the Model 1018RC “sees” RTS and
when it sends CTS. Currently, the Model 1018RC does not have
optional delay settings. “No Delay” is defined as between 500 nsec and
1 msec. The switches should remain in the “OFF” position.
