CPU BOARD, 562-055

The CPU board has a jumper package (Jl) and a switch package (S2). By setting these packages you select the
operating parameters for the system.

firealarmresources.com

BAUD RATE SELECTION
Jumper package Jl (Figure 1) is used to select three baud rates. Once the baud rate is selected, it will be
available for use by any controller or device in the system. Unless specified at order entry, the standard system
configuration will be:
COMMUNICATIONS = 4800 Baud (Jumper from Pin 1to Pin 16)
LOCAL PRINTER = 1200 Baud (Jumper from Pin 5 to Pin 13)
REMOTE PORT = 300 Baud (Jumper from Pin 7 to Pin 11)
Jl
- BAUD 3 1
I BAUD 2
- BAUD 1
FIGURE 1 FIGURE 2
This jumper package will be factory-preset. The only time you need be concerned with it is when replacing a
defective CPU board. In this case, remove the pluggable jumper package from the defective board and install it
on your replacement board.
Switch package S2 (Figure 2) is used to notify the system of specific operating conditions. Switch settings and
their functions are given in Table A.

24K PRAM BOARD, 5621049

PROM MEMORY
SELECT
J2 Ji
PROM MEMORY RAM MEMORY
SELECT SELECT 54
A memory board containing PROM and RAM memory chips is referred to as a PRAM board. On each PRAM
board there are three blocks containing 8K of memory each (one block of RAM and two blocks of PROM). A
starting address must be selected for each block of memory.
Before setting the switches, let’s look at a PROM label. PROMS are located in IC sockets 1 through 8. The first
line of information on the label is the program number. The second line tells what card this is and what IC socket
this chip goes into. The third line is the date the chip was programmed. For example,
H901102C
cl
PROGRAM NUMBER
CARD2lC3 PRAM BOARD 2 AND THIS CHIP GOES IN IC SOCKET 3
7-8-82 THIS CHIP WAS PROGRAMMED JULY 8TH 1982
Since the memory mix between PROM and RAM is customer-sensitive, there is no standard way to set the switch
packages. However, if you perform the following procedure, the switches will be set correctly.
First, remove the PRAM boards and lay them on a static-free surface. Open all switches on switch packages Jl ,
J2, and J3. Then perform the following procedures.

firealarmresources.com

Note: If your system does not use the PRAM card specified in B through D below, proceed to RAM MEMORY
SELECTION. If AT ANY TIME you have closed a total of 8 switches (regardless of what step you are on),
proceed to SYSTEMS WITH MEMORY EXPANSION.
A. PRAM CARD 1
1. There is ALWAYS a PROM chip in IC8 of PRAM card 1,so close switch 7 on switch package J3.
2. If there is a PROM chip on ICl , close switch 8 on switch package J2. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
B. PRAM CARD 2
3. If there is a PROM chip in IC8, close switch 6 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
4. If there is a PROM chip in ICl, close switch 5 on switch package J2. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
C. PRAM CARD 3
5. If there is a PROM chip in IC8, close switch 4 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
6. If there is a PROM chip in ICl, close switch 3 on switch package 52. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
D. PRAM CARD 4
7. If there is a PROM chip in IC8, close switch 2 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
E. RAM MEMORY SELECTION
Note: You have now set switches to address all of your PROM memory in the system. You are now prepared
to set switches for addressing all RAM memory which will be used. Proceed to Step 8. If your system
does not use the specified PRAM card, or if your count of closed switches reaches 8, go to SYSTEMS
WITH MEMORY EXPANSION.
8. On PRAM card 1, close switch 1 on switch package Jl .
9. On PRAM card 2, close switch 2 on switch package Jl .
10. On PRAM card 3, close switch 3 on switch package Jl .
11. On PRAM card 4, close switch 4 on switch package Jl .
12. On PRAM card 5, close switch 5 on switch package Jl.
13. On PRAM card 6, close switch 6 on switch package Jl .
14. On PRAM card 7, close switch 8 on switch package Jl .
Note: At this point all your RAM and PROM memory has been addressed. Switch package J4 is used for
systems with memory expansion. it will NOT be used with this PRAM board (562-049) so set all J4
switch packages as follows:
CLOSE switches 1,3, and 5
OPEN switches 2,4,6, 7, and 8
IMPORTANT NOTE!
ENSURE THAT ONLY ONE ROLL SWITCH ON EACH SWITCH PACKAGE (Jl, J2, AND J3) IS CLOSED.

32K PRAM BOARD, 562-305
The 32K PRAM memory board has three switch packages. Switch package Sl is used to set the board number
and address range. Switch packages S2 and S3 are used to select RAM or PROM memory chips.
Before setting the switches, let’s look at a PROM label. PROMS are located in IC sockets 9 through 24. The first
‘line of information on the label is the program number. The second line tells what card this is and what IC socket
this chip goes into. The third line is the date the chip was programmed. For example,
H901102C
cl
PROGRAM NUMBER
CARD2lC9 PRAM BOARD 2 AND THIS CHIP GOES INTO IC SOCKET 9
3-l 5-83 THIS CHIP WAS PROGRAMMED ON MARCH 15,1983
To set the switches on switch package Sl , use the illustration above and Table B.
To set the switches on switch packages S2 and S3 you must first determine the status of IC sockets 9 through
24. Each of these will either be occupied by a RAM or PROM chip, or will be empty. Use the illustration above
and Table C to set the switches.

The 96K PRAM board was designed primarily to increase the 2120 memory capacity and decrease the number
of BMUX slots required for memory boards. Each bank of memory is still 32K, but there are now three 32K banks
on each 96K PRAM board. In terms of 32K PRAM boards,
ONE 96K PRAM Board = THREE 32K PRAM Boards
As shown in the illustration above, the three banks on each 96K PRAM board are referred to as bank A, bank
8, and bank C.
The upper bank, also called the common bank, hotds the system’s main (executive) operating program. In all
2120 systems using 96K PRAM boards, bank A on the first PRAM board is designated as common.
The 96K PRAM board has five switch packages. Switch packages Sl and S2 are used to select system common
memory and “standard” banks. Switch packages S3, S4, and S5 are used to set each bank’s address range.
Although the 96K PRAM board contains both PROMS and RAMS, its design eliminates the need to identify
whether a slot contains a PROM or RAM chip.
Before setting the switches, let’s look at a PROM label. The first line of information on the label is the program
number. The second line tells what card this is and what IC socket this PROM goes into. The third line is the date
the chip was programmed. For example,
PROGRAM NUMBER
PRAM BOARD 1AND THIS PROM GOES INTO IC SOCKET 16
THIS CHIP WAS PROGRAMMED ON MARCH 23,1984
Set the switches on switch packages Sl through S5 usingTable D and the 96K PRAM board illustration above.

CHANNEL 1
A DC transmission board is required for each communication channel used in the system (up to 2). Each board
has a switch package (Jl) which is used to select the baud rate and the associated channel address. Except for
the setting of switch package Jl ,the transmission boardfor Channel 1 is identical to that for Channel 2.
When the transmission board is used for Channel 1, switch 8 of Jl will be CLOSED. When it is used for Channel
2, switch 7 of Jl will be CLOSED.
To determine the selected baud rate for your communication channel(s), refer to the 2120 CPU board, jumper
package Jl (see Figure 1). Close the corresponding switch on switch package Jl on the transmission board.
CAUTIqN: If you close more than two switches on Jl ,you will destroy the CPU board’s baud rate generator!

ALWAYS be CLOSED:
J2 -- switches 1 and 3

The selection of switches for Port 2 depends on the peripheral device being used. If Port 2 is being used for any
of the following devices, the switches should be set as shown in Figure 4:
- Model 43 Teletype - G.E. Terminette - ADDS CRT
