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 shallPatton Electronicsbe 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 Electronicsspecifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be

1.1RADIO AND TV INTERFERENCE

The Model IM1RC/D 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 IM1RC/D 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 IM1RC/D
does cause interference to radio or television reception, which can be
determined by disconnecting the unit, 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 use only
data cables with an external outer shield bonded to a metal or metal­ized connector at both ends. Shielded cables must be used on the net­work connection to satisfy compliance with the Electromagnetic
Compatibility (EMC) directive.

2.2 DESCRIPTION

The Patton Model IM1RC/D is an option board which implements

a low-power X.21 interface. The Model IM1RC/D is designed for use
with Patton Electronics rack cards: 1045RC, 1092RC, 1092ARC,
1095RC, 2500RC, 2703RC and 2715RC. The Model IM1RC/D sup­ports data rates up to 2.304 Mbps. The DCE and DTE interface is com­patible with X.21 specifications

The Model IM1RC/D provides an X.21 electrical interface. This section
describes how to properly install the X.21 daughter board to operate in DCE or
DTE mode and defines the jumper settings and its function.

3.1 INSTALLING IM1RC/D (X.21 Daughter Board)

Figure 1 (below) shows the X.21 daughter board, DCE/DTE selector and
jumper (JP1) location with respect to the rack card. Following figure 1 are
guidelines for the installation of the X.21 daughter board, setting for DCE/DTE
and a brief description on Jumper JP1.

Follow the steps below for proper installation of the X.21 daughter board.

WARNING:

The X.21 daughter board connector is not keyed and

can be installed incorrectly.

1. On the top side of the X.21 daughter board, locate the designator
shown:

Front X.21

2. Install the X.21 daughter board onto the front card with the “

3.1.1 DCE/DTE Selector

The X.21 daughter board can be set up as DCE (default) or DTE device.
The DCE/DTE selector must be installed in the X.21 daughter board for any
configurations. The following information describes the setting for DCE/DTE.

DCE Setting:
(Default)

DTE Setting:

To set a rack card as a DCE device install the DCE/DTE
selector with the DCE arrows pointing toward the front
panel.

To set a rack card as a DTE device, install the DCE/DTE
selector with the DTE arrows pointing toward the front
panel.

3.1.2 Jumper (JP1) Setting

The X.21 daughter board operates at speeds up to 2.3Mbps. When using
the daughter board at data rates of 2Mbps or higher, clocking issues may intro­duce bit errors. Bit errors can also occur when long cables are used to inter­connect the modem to an X.21 terminal device (router, mux, etc.) To solve bit
error problems due to speed and/or long cables, the X.21 daughtherboard is
equipped with a jumper selector (JP1) that changes the sampling edge of the
transmit clock. Please refer to figure 1 (for Jumper JP1 Location).

The following is a brief description of JP1 setting and functionality.

Normal Setting:

Jumper shorts the two outer pins of JP1. Figure 1 shows
default postion. This position is selected when operating at
low data rate (less than 2Mbps), and using a short X.21
terminal cable.
