DESCRIPTION

Printed Circuit Boards

A 2100/2120 interface Kit is required for each 2100 transponder which will be required to communicate with a

2120 BMUX. This kit consists of two printed circuit boards which will replace the 2100 Transmission and the
Controller boards in the 2100 transponder. The new Communications board can be identified by two yellow and
one red LED on the outside edge of the board. The new Controller board has a single green LED on it and also
contains an 87C51 microcontroller IC.

Transient Protection

A Simplex Model 2081-9027 Isolated Loop Circuit Protector is required on both sides of any communications line
that leaves the building.

Distance Restrktions

If the 2100 transponder is located more than 10,000 feet (1.9 miles) from the BMUX, a DC repeater or a modem
is required.

PC Board Preparation

IMPORTANT: Use the Anti-static Kit (Part No. 553-503) when handling these boards.

Communications Board

If not operated in McCulloh (style 7) no alterations need to be made to the board. If operated in style 7, contact
Service Support at Headquarters.

Controller Board

There are three banks of dip switches on the controller board which must be configured properly for the

transponder to operate. These switch banks are read and stored by the microcontroller upon power up or when

the RESET button is pressed. If the settings are changed once the transponder is powered up, the RESET

button must be pressed or the power must be removed and re-applied for the new settings to be read and
stored.

Encoder Card Address Switch Settings (SW1 and SW2)

Dip switches on switch banks SW1 and SW2 are numbered 0 to 15 and are set ON if their number corresponds
to an encoder card address present in the transponder. These addresses are found by either (a) looking them up
on the 2100 TRANSPONDER SPECIFICATION SHEETS for the particular job being converted or by (b) reading
the jumpers on the mother board of the transponder. These four jumpers are located next to the encoder card’s
connector. (See Figure 2.) Each jumper corresponds to a bit in a four-bit address and is either a binary one by

being connected to + 12 Volts or a binary zero by being connected to GND. To determine the address, simply

add up the binary weights for each bit tied to + 12 Volts.

Example: (Refer to Figure 2)

The jumpers on the second encoder card are con-

nected as follows:

1B 4 GND
28 + +12V
48 --+ GND
88 --+ +12v

This encoder card has an address of 2 + 8 = 10.

Once the encoder card address is determined, set
the appropriate dip switch located along the edge
of the board to ON. These switches are split into
two switch banks. The first bank is next to the

reset button and is labeled EC numbers 0 to 7 for

encoder numbers 0 thru 7. The second bank is

next to the side of the board and labeled EC
numbers 8 to 15 for encoder numbers 8 thru 15.

Repeat the procedure for every encoder card in

the transponder (up to ten).

Note: If a dip switch is set for an encoder card

which does not exist, an error will be
reported. Likewise, if a dip switch is not set ’
for an encoder card present in the
transponder, an error will be reported.

According to the jumpers, the address
for the encoder in slot J2 would be

1010 in binary or address 10.

Transponder Address Setting

Switches 3 through 8 of switch bank SW3 are for setting the transponder address. Each dip switch carries a binary
weight corresponding to its position. These switches are labeled “ADDR” and the switches with a binary weight
of 1 and 32 are marked. The address of the transponder in the example shown in Figure 3 is 18.

The 2100 transponder requires two transponder addresses. The first address is the monitor point transponder
address, the second is the control point transponder address. Set the ADDR dip switches to the address of the
first transponder. (The second transponder always occupies the next consecutive address.) This is done in the

identical manner which other 2120 transponder addresses are set. Remember, the transponder address is always
one less than the transponder number.

INSTALLATION INSTRUCTIONS

1. Power down the 2100 transponder by disconnecting both battery and AC power.

2. Prepare the 2100 Transponder and the 2100/2120 Interface boards as described above.

3. Insert the communication board in the slot which the 2100 Transmission board previously occupied. If the *
2120 is transmitting, the two yellow LED s will flicker indicating reception of DC transmissions. The LED s
are labeled PRI and SEC and indicate activity on the primary and secondary channels of the transponder.
(The A’ and B’ terminals on the 2100 are the primary terminals.)

4. Insert the controller board in the slot previously occupied by the 2100 Controller board.

5. Apply first AC power and then battery power to the transponder while observing the green “ON LINE” LED
for 10 seconds.

l

Replace the controller board if either:

A. The LED fails to flash at a high rate (about 10 flashes/second) upon power up.

B. The LED continues flashing at a high rate 10 or more seconds after power on.

Note: The 8-second watch dog timer test which takes place while the green LED flashes at a high rate can be

bypassed by pressing the RESET button.

6. Check the green “ON LINE” LED again.

l

If it is not on steady, refer to the TROUBLE DIAGNOSIS chart below.

7. If the green ON LINE LED remains lit, replace the cover over the PC boards on the transponder. Close
and secure the transponder door. Installation is complete.

NOTE:

In general, if the green LED is off, it indicates that the transponder is not communicating.with the 2120 and that

communications have been interrupted for ten seconds or longer. A flashing

ADDITIONAL INFORMATION

2100 System Overview

CHANNEL 1 = MONITOR POINTS l- 64 + CONTROL POINTS l- 48

CHANNEL 2 = MONITOR POINTS 65-128 + CONTROL POINTS 49- 96

CHANNEL 3 = MONITOR POINTS 129-192 + CONTROL POINTS 97-144

CHANNEL 4 = MONITOR POINTS 193-256 + CONTROL POINTS 145-192

CHANNEL 5 = MONITOR POINTS 257-320 + CONTROL POINTS 193-240

CHANNEL 6 = MONITOR

POINTS 321-384 + CONTROL POINTS 241-288

CHANNEL 7 = MONITOR POINTS 385-448 + CONTROL POINTS 289-336

CHANNEL 8 = MONITOR POINTS 449-512 + CONTROL POINTS 337-384

A 2106 system can have up to 8 channels using separate communication lines for each channel.

Each 2100 encoder has 4 monitor points and 3 control points.

Each 2100 transponder can have up to 40 monitor points and 36 control points for a total of 10
encoders within the same 6 unit cabinet.

Maximum of 16 encoders for a total of 64 monitor points and 48 control points per channel.

Maximum of 10 encoders in a 6 unit cabinet.

Maximum of 6 encoders in a 4 unit cabinet.

Maximum of 3 encoders in a 2 unit cabinet.

In converting the 2100 system to a 2120 configuration, the existing four to eight 2100 channels will be reduced
to one or two 2120 channels (depending on the system requirements).

l

This will necessitate communication line wiring and hardware changes.

Interface Operation

The 2100/2120 Interface scans the 2100 encoders in numerical order, configuring them into 2120 transponder
slots from the lowest to the highest encoder address (missing addresses are ignored). All monitor points appear
on the first address; all control points appear on the second address.

Example: A 2100 transponder cabinet on channel 1 contains encoders 00, 01,02, 07, 08.

The 2120 transponder addresses to be assigned to this cabinet are 105/l 06.

Under the above conditions, point relationships are as follows:
