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

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).

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

4.0 INSTALLATION

Figure 3. Model 1000R16P Rack Chassis with power supply

This section describes the functions of the Model 1000R16P rack
chassis, tells how to install front and rear Model 1000CC cards into the
chassis and provides diagrams for wiring up the interface connections
correctly.

4.1 THE MODEL 1000R16P RACK CHASSIS

The Model 1000R16P Rack Chassis (Figure 3, below) has sixteen
short range modem card slots, plus its own power supply. Measuring
only 3.5” high, the Model 1000R16P is designed to occupy only 2U in a
19” rack. Sturdy front handles allow the Model 1000R16P to be
extracted and transported conveniently.

4.1.1 THE RACK POWER SUPPLY

The power supply included in the Model 1000R16P rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by thumb screws and the rear card by
conventional metal screws.

Replacing the Power Supply Fuse

The rack chassis power supply uses a 400mA fuse for 120V AC
circuits, and a 200mA fuse for 240V AC circuits. The fuse compartment
is located just below the AC socket on the rear card. To replace the
fuse, follow these steps:

1. Using a small screwdriver, pop the compartment open: It will slide

open like a drawer. Depending upon the exact part used, the
drawer may slide completely out of the fuse holder or it may stop
partway out.

2. Note that there are

two

fuses in the drawer: The front fuse is the

spare, the rear fuse is the “active” fuse.

3. If the active fuse appears to be blown, remove it from the clips and

replace it with the spare from the front compartment. Note the size
and rating of the blown fuse before discarding.

4. Using the part number found in Appendix C, order a new

replacement fuse.

Warning: For continued protection against the risk of fire, replace
only with the same type and rating of fuse.

Switching the Power Supply Between 120 and 240 Volts

Although the Model 1000R16P is shipped from the factory with a
customer-specified power supply configuration, you may change the
configuration yourself. Here are the steps to switch the configuration of
the power supply between 120V and 240V AC:

1. Remove the front power supply card and locate the two position

switch near the back of the card. Slide the switch to the desired
voltage (Note: The actual values on the switch may be “110/220” or
“115/230”).

Switching the Power Supply On and Off

The power switch is located on the front panel. When plugged in
and switched on, a red front panel LED will glow. Since the Model
1000R16P is a “hot swappable” rack,

to be installed before switching on the power supply

it is not necessary for any cards

. The power supply

may be switched off at any time without harming the installed cards.

2. Replace the existing fuse with one of the correct value (see
Appendix C for the appropriate fuse).

3. Replace the power supply cord, if necessary (see Appendix C for
the appropriate power cord).

4.2 INSTALLING THE MODEL 1000CC INTO THE CHASSIS

Figure 4. Local daisy chain.

The Model 1000CC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other via
mating 50 pin card edge connectors. The following steps demonstrate
the installation of the Model 1000CC into the chassis:

1. Slide the rear card into the back of the chassis along the metal

rails.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should meet the

rear card when it's almost all the way into the chassis.

gently

4. Push the front card

into the card-edge receptacle of the rear

card. It should “click” into place.

5. Secure the front card using the thumb screws.

Note: Since the Model 1000R16P chassis allows “hot swapping”
of cards, it is not necessary to power down the rack when you
install or remove a Model 1000CC.

4.3 RS-232 TERMINAL CONNECTION (PORT “A1”)

The 10-pin RJ-45 port labeled “A1” is wired as a DCE, and is
designed to connect to a the serial port of an RS-232 terminal (DTE).
This port is pinned according Patton's Modified Modular Interface
Standard, which is based on the EIA/TIA-561 Standard (for specific
pinouts, see Appendix C). Note: DSR, CTS and CD outputs are
always ”high” (+8V).

When making a connection between port A1 and the serial port of
an RS-232 terminal, your cable should be wired

straight through

. Note:
if your terminal device does not have a modular RJ-45 port, you will
need to construct an adapter cable according to the pinouts in
Appendix C. A pre-made DB-25 to RJ-45 adapter is also available
from Patton Electronics. This may be used in conjunction with a
straight through modular cable (also available from Patton). Refer to
Appendix B for the correct part number when ordering these items.

Standard (based on the EIA/TIA-561Standard). For daisy chain
connection between racks, use an 8 or 10 position modular cable wired

straight through

Note
Note

: DTR and RTS outputs are always “high” (+8V).

2

: The DSR input must be “high” in order fo the daisy chain port
to operate. This is provided automatically when the B1 port is
connected to the A1 port of another Model 1000CC.

4.4.1 LOCAL DAISY CHAIN TOPOLOGY

Figure 4 (below), shows a typical daisy chain connection using a
remote terminal, two racks and two Model 1000CCs. Using this type of
topology, one terminal can control several racks in the same location.

To wire up a local Model 1000CC daisy chain connection, follow these
steps:

1) Using a straight through modular cable, connect the serial

port of the RS-232 terminal to Port A1 of the first Model 1000CC in

the chain.

2) Using a straight through modular cable, connect Port B1 of

the first Model 1000CC in the chain to port A1 of the second Model

1000CC in the chain. Follow the same procedure from the second

to the third Model 1000CC (and so on) if there are additional units in

the chain.

4.4.2 REMOTE DAISY CHAIN TOPOLOGY

4.4 RS-232 DAISY CHAIN CONNECTION (PORT “B1”)

The 10-pin RJ-45 port labeled B1 is wired as a DTE, and is
designed to connect to port A1 of another Model 1000CC. Like port A1,
this port is pinned according Patton's Modified Modular Interface

(continued)

In some applications it may be desirable to control a local rack and
a remote rack using the same local RS-232 terminal. This can be
accomplished using two of Patton’s RS-232 short range modem cards
in addition to the Model 1000CCs.

5.0 OPERATION

Once you have configured each Model 1000CC and connected the
cables, you are ready to operate the unit. Section 5.0 describes the
LED status monitors, the power-up procedure, and use of the Model
1000CC.

5.1 LED STATUS MONITORS

The Model 1000CC features five front panel LEDs that indicate the
condition of the modem and communication link. These LEDs operate
as follows:

• The green “PWR” LED glows when power is applied to the
modem through its mid-plane chassis connection.

• The green “TD” and “RD” LEDs show positive state data
activity. The red “TD” and “RD” LEDs show negative state
data activity. A solid red light indicates an idle state.

5.2 POWER-UP

There is no power switch on the Model 1000CC: Power is
automatically applied to the 1000CC when its card-edge connector
touches the chassis’ mid-plane socket, or when the chassis’ power is
turned on.

Note: The 1000CC is a “hot swappable” card—it will not be

damaged by plugging it in or removing it while the rack is powered up.

5.3 CONTROLLING CSU/DSU CARDS

The Model 1000CC has one primary purpose: to receive instructions
from an RS-232 terminal and pass them to one or more Patton
CSU/DSU rack cards through the midplane bus of a Patton rack chassis
or Cluster Box. Once the Model 1000CC is installed and configured
properly, you should refer to Section 4.4 of the Patton Model 2500
Series Manual for information about control port configuration and
control port commands.

Note: Each CSU/DSU card has its own address, which is set using the
Address Rotary Switches on the card. In order to receive instructions
individually, each card musthave a

unique address

(00 - 98). Cards set
to “99” will listen to group instructions, but will not be able to discern
instructions individually.

Figure 5. Remote daisy chain

is also possible to combine this remote daisy chaining method with the
local daisy chaining method described in Section 4.4.1.

To wire up a remote Model 1000CC daisy chain connection, follow
these steps:

1) Using a straight through modular cable, connect the serial
port of the RS-232 terminal to Port A1 of the local Model 1000CC.

2) Using a

straight through

modular cable, connect Port B1 of
the local Model 1000CC to port A1 to the RS-232 port of a Patton
asynchronous short range modem card (ex. the Model 1000RC).

3) Following the instructions in the User Manual for the particular
Patton short range modem card you are using, connect the “line”
port of the local short range modem card to “line” port of the remote
short range modem card. This connection should be made in the
normal manner, using twisted pair cable.

4) Connect the serial (RS-232) port of the remote Patton short
range modem card to Port A1 of the remote Model 1000CC. Since
both ports are configured as DCE, you will need to use a modular
RJ-45

crossover

cable pinned in the following manner:
