1.0 WARRANTY INFORMATION

2.0 GENERAL INFORMATION

Patton Electronics warrants all Model 1000CC 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 1000CC 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 1000CC 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
1000CC does cause interference to radio or television reception, which
can be determined by turning the power off or disconnecting the
RS-232 interface, the user is encouraged to try to correct the
interference by one 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).

1.2 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 Service at [phone].

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 1000CC. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

2.1 FEATURES

• Lets an async RS-232 terminal configure or dial Patton’s
2500RC Series of CSU/DSU rack cards

• Fits in Patton’s rack chassis and Cluster Boxes

• Supports RS-232 terminal data rates to 19.2 Kbps

• Daisy chain capability lets one terminal control many racks

• Works in conjunction with Patton short range modem rack cards to
provide remote daisy chain option

2.2 DESCRIPTION

The Model 1000CC RS-232 Rack Mount Controller Card fits in

Patton’s rack chassis and Cluster Boxes and allows the 2500RC family
of CSU/DSUs to be configured and controlled from an asynchronous
RS-232 terminal. Taking up one card slot, the Model 1000CC provides
one modular port for connection of an RS-232 terminal, and a second
modular port for daisy-chaining between racks. The user wishing to
“dial” or configure a particular CSU/DSU card simply keys in an
addressable command, which the Model 1000CC passes along to all
the cards in the rack. The appropriate card recognizes its address and
responds to the command.

Daisy-chaining with one or more other racks containing a Model

1000CC can be done locally or remotely. To accomplish remote daisy­chaining, the daisy-chain port of a Model 1000CC is connected to a
Patton short range modem card. The terminal link is then driven to a
remote rack with a second short haul and a Model 1000CC.
Combining local and remote daisy chaining, a single RS-232 terminal
can control a whole network of Patton CSU/DSUs. The Model 1000CC
has front panel LED indicators for Power, TD and RD. A special rear
card, the Model 1000RCM1C45, is supplied with the unit. Other rear
cards are also compatible with the Model 1000CC.

DTE as DSR or RI (JB6 & JB7)

Because this rear card is designed to function in more applications
than the Model 1000CC, this jumper must be installed only in one
position. Place the jumper across pins 1&2 so that the terminal (DTE)
sees DSR as high when the DTE raises DTR. The other positions,
across pins 2&3, are for Ring Indicate as defined by EIA/TIA-561. The
RI function is irrelevant (and on the Model 1000CC is also
disconnected) and can cause improper operation if the jumper is
installed incorrectly.

3.0 CONFIGURATION

The Model 1000CC has no configuration straps or switches, except

those associated with the rear card. These are described below.

3.1 REAR CARD CONFIGURATION

The rear card supplied with the Model 1000CC is equipped with two
modular RJ-45 jacks (see Figure 1, below). The jack labeled “A1” is for
connection to the RS-232 terminal. If the Model 1000CC is being used
in a daisy-chain application, port “B1” provides the link to the next
Model 1000CC in the chain.

3.1.1 REAR CARD STRAP SETTINGS

Figure 2 (below) shows the two possible settings for each strap.
The PC board is labeled with the “123” orientation.
