The sy st em PC B s con tai n d igi t al c ir c uit r y whi c h, whil e ext r eme ly re li ab le ,
can b e d amag ed by expos ure to excess iv e s ta tic electricity. W hen
handling PCBs, a grounded wrist strap should be used to protect the
boards from static discharge s. Also, use common se nse whe n hand ling
PCBs. For e xample , do not place a PC B in loca tions where hea vy ob je cts
mig ht fal l on the PCB an d da mage compon ents.
In sert in g a P CB
1. Hold the PC B by th e injector ta bs and, with the compone nts fa cing

2. SlidethecardintothesystemandusetheinjectorstoseatthePCB

Remov ing a PC B

There is a ground tab located on the top and bottom of each PCB towa rd
the front end of the card. There is also a ground tab located to the right o f

groundtab oneachcard mates with the ground tabon each cardguide.
This ensure a good ground potential to reduce RFI and EMI interference

The MPB is installed in the right most PCB card slot (slot MPB) of the
BKSU. The MPB contains a lithium dry-ce ll to ma intain m emory a nd
real-time clock functions. The battery is soldered to the MPB and
connected to the circuitry by an On-Off DIP switch. Make sure the DIP

Before progra mming the sys te m, switch 8 should be p lace d in the ON
position and power cycled off and on to initialize the sy stem databa se to
default. Once the database has been initialized, switch 8 should be
pl aced in th e O FF pos it ion so as to prot e ct t he dat ab ase .
Software for the syste m is contained on two ch ips , labe led U1 and U3.
The MPB is shipped with these chips in place so you should not have to
installthesoftware.However,ifasoftwareupgradeispurchased,you
must rep lace the existing chips.
Removing Existing Software
Before starting this procedure, you must have an Integrated Circuit (IC)
Extractor tool to remove the current EPROMs from the Printed Circuit
Board.
1. Locate and remove EPROMs U1 and U3 on the MPB board. These
EPRO Ms must be r em oved a nd re pl aced wit h EPRO Ms la bel ed U1 a nd
U3. Using the IC tool, gently pull upwards until the EPROM lifts free of
the s ocket. Be ca reful not to bend or break the pins of the EPROMs.
2. Place the EPROMs on a non- static, n on-conductive surface until the
ne w s oftware is ins ta lled. The n place the EPROMs into the pack aging
tube and put this into the packing box.
In sta l li ng Ne w Soft ware
1. Remove the EPROMs from the packing tube.
2. Install EPROMs U1 and U3 onto the Master Processor Unit. Be sure the
no tche d end (end with cutout) is aligne d with the notch ed e nd of the
s ocket(s ).
3 . Whe n t he EPROMS ar e ins ta ll ed, check for be nt pins on the E PRO Ms
a nd correct any found.
4 . Wi th the l it hi u m b att er i es and dau gh te r bo ar ds ins tal l ed, ins er t t he
MPB in s lot MPB of th e BKSU. Refer toFi gur e 2-1 2.
