1.1 RADIO AND TV INTERFERENCE

The Model 1205RC 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 1205RC 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 interfer-

ence will not occur in a particular installation. If the Model 1205RC

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 fol-

lowing measures: moving the computing equipment away from the

receiver, re-orienting the receiving antenna and/or plugging the receiv-

ing equipment into a different AC outlet (such that the computing equip-

ment 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 exter-

nal outer shield bonded to a metal or metalized connector; and, config-

ure the rear card as shown in section 3.4 of this manual.

2.2 DESCRIPTION

The Patton Model 1205RC synchronous modem eliminator

rack card lets two synchronous hosts communicate with each other in

the same room for a fraction of the cost of a pair of high speed

modems. Supporting synchronous data rates of 32, 48, 56, 64, 72,

112, 128 and 144 Kbps, the Model 1205RC can be configured to emu-

late dial-up or leased line service. Maximum distance between the

connected hosts is 300 feet. Timing can be set for internal or external

clock, and all necessary data, clocking and control signals are support-

ed.

The Model 1205RC is designed to mount in Patton’s 2U high, 16-

slot rack chassis, as well as Patton’s 2/4/8-slot desktop Cluster Boxes.

This rack chassis and cluster boxes feature a switchable 120/240 VAC

power supply (optional 48 VDC) and hot swappable function/interface

cards mounted in a mid-plane architecture. Front panel LEDs show

TD, DTR and CD activity for both ports, as well as power. The rear

interface card has two UD-26 connectors for patching to the host

devices.

3.0 CONFIGURATION

This section describes the location and orientation of the Model

1205RC’s configuration switches and jumpers, and provides detailed

instructions for all possible settings.

The Model 1205RC uses a combination of DIP switches and

jumpers that allow configuration to an extremely wide range of applica-

tions. Designed around a mid-plane architecture, the Model 1205RC

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 1205RC is

designed to operate transparently, without need for frequent re-config-

uration: just set it and forget it!

3.1 FUNCTION CARD CONFIGURATION

All switches and jumpers are located on the Model 1205RC’s PC

board. To access the PC board, loosen the two thumb screws on the

front panel and slide the card out of the chassis. As Figure 1 (below)

illustrates, the DIP switches are located on the “daughterboard” and

the jumpers are located on the main PC board.

3.1.1 FUNCTION CARD DIP SWITCH

The Model 1205RC has one four-position DIP switch mounted on

the daughterboard. Figure 2 (following page) shows the numbering of

the individual switches and their “ON/OFF” positions relative to the

daughterboard.

Figure 1. Model 1205RC board, showing location of switches/jumper

5.2 POWER-UP

There is no power switch on the Model 1205RC: Power is auto-

matically applied to the 1205RC when its card-edge connector makes

contact with the chassis’ mid-plane socket, or when the chassis’ power

supply is turned on. Note: The 1205RC is a “hot swappable” card—it

will not be damaged by plugging it in or removing it while the rack is

powered up.

When the Model 1205RC is powered up, and both ports are pass-

ing data normally, the following LED conditions will exist:

• PWR = green

• TD = blinking red and green

• CD = green

• DTR = green

5.0 OPERATION

Once you have configured the Model 1205RC and connected the

cables to host A and host B, you are ready to operate the unit. This

section describes the LED status monitors and power-up procedure.

5.1 LED STATUS MONITORS

The Model 1205RC features 13 front panel status LEDs that indi-

cate the condition of the Model 1205RC and the two ports, A & B (see

Figure 9, above):

• The green “PWR” LED glows green when power is applied to the

Model 1205RC through its mid-plane chassis connection.

• Two “TD” LEDs monitor the status of each port’s data transmis-

sion. The red LED glows when the signal is in an idle (negative)

state. The green LED glows when the signal is in a transmitting

(positive) state. Both LEDs will normally blink when data transmis-

sion is occurring.

• Two “CD” LEDs monitor the status of each port’s carrier detect sig-

nal. The red LED glows when the receive channel is not active

(negative condition). The green LED glows when the receive

channel is active (positive condition).

• Two “DTR” LEDs monitor the status of DTR for each port. The red

LED glows to indicate that the host device connected to that port

is not ready to communicate (negative condition). The green LED

glows to indicate that the host device connected to that port is

ready to communicate (positive condition).

3.3 FUNCTION CARD JUMPERS

The Model 1205RC has two ports (Port A and Port B), and each

must be configured independently. Therefore, every function (such as

clocking) has two jumpers associated with it. As Figure 3 (below)

shows, each jumper has three possible positions: strap covering posts

1 & 2, strap covering posts 2 & 3, or strap removed altogether. The

detailed description for each jumper presents all valid strap positions.

Front of Card

123 123

The Model 1205RC has six jumpers (JP1,thru JP6) mounted on

the PC board (see Figure 4, below). These jumpers set clocking, carri-

er, and RTS/CTS delay independently for ports A and B.

JP1: RTS/CTS Delay (Port A)

The setting for jumper JP1 determines–with respect to Port A– the

amount of delay between the time the Model 1205RC “sees” RTS and

when it sends CTS. In order to emulate either dial-up or leased line

modems, you can set this strap at either 0 msec, 7 msec or 53 msec.

JP1 Setting

Position 1&2 7 msec Delay (factory default)

Position 2&3 53 msec Delay

Strap Removed 0 msec Delay

JP6: RTS/CTS Delay (Port B)

The setting for jumper JP6 determines–with respect to Port B– the

amount of delay between the time the Model 1205RC “sees” RTS and

when it sends CTS. In order to emulate either dial-up or leased line

modems, you can set this strap at either 0 msec, 7 msec or 53 msec.

4.3 HOST (DTE) CONNECTION

The Model 1205RC rear card has two UD-26 connectors, labeled

“A1” and “B1” (see figure 7, below). These correspond to host (DTE)

connection Port A and Port B, as discussed in Section 3.0.

To connect V.35 host (DTE) devices A and B to the Model

1205RC, follow these instructions:

1. Configure the Model 1205RC for your specific application accord-

ing to the instructions in Section 3.0 of this manual.

2. Connect host devices A and B to the Model 1205RC using multi-

pair adapter cables (see Appendix B for a list of custom adapter

cables available from Patton Electronics). Observe the following

conditions when making connections :

a) Each multipair cable must not exceed 150 feet in length

(see Figure 8, below).

b) If external clock is used, the host (DTE) device supplying the

clock must be connected to Port A. The Model 1205RC

cannot receive an external clock on Port B (see Section 3.0

for configuration details).

c) If receive clock is used on Port B, Port A must supply an

external clock (see Section 3.0 for configuration details).

Notice! Any terminal cable connected to the Model

1205RC must be shielded cable, and the outer shield must

be 360 degree bonded–at both ends–to a metal or metal-

ized backshell.

Switching the Power Supply On and Off

The power supply on/off switch is located on the front panel.

When plugged in and switched on, a red front panel LED will glow.

Since the Model 1000R16 is a “hot swappable” rack, it is not necessary

for any cards to be installed before switching on the power supply.

The power supply may be switched off at any time without harming the

installed cards.

NOTE: Please refer to the Model 1000RP Series User Manual AC

and DC Rack Mount Power Supplies for fuse and power card

replacement information.

4.2 INSTALLING THE MODEL 1205RC INTO THE CHASSIS

The Model 1205RC is comprised of a front card and a rear card.

The two cards meet inside the rack chassis and plug into each other by

way of mating 50 pin card edge connectors. Use the following steps

as a guideline for installing each Model 1205RC into the rack chassis:

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

metal rails provided.

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

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

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

4. Push the front card gently 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 1000R16 chassis allows “hot swapping”

of cards, it is not necessary to power down the rack when you

install or remove a Model 1205RC.

3.4 REAR CARD CONFIGURATION

The rear interface card for the Model 1205RC is equipped with two

female UD-26 connectors: one for each DTE host port. This card has

one configuration jumper (JB4). Figure 5 (below) shows the location of

this jumper on the PC board.

SGND & FRGND (JB4)

In the connected position, this jumper links UD-26 pin 7 (Signal

Ground) and frame ground. In the open position, pin 1 is “lifted” from

frame ground.
