What is Chipper Check II (CCII)?
ChipperCheckIIisanadvanced interfaceboxthat providescommunicationbetween theTV
setbeingservicedandapersonalcomputer. TheinterfaceconvertstheI2Cbuscommunication
oftheTV toserialcommunication usedbythe PC. WiththeChipperChecksoftware,thePC
isabletocontrol certain functionsoftheTVand perform some alignments.
OtherfunctionsofCCIIaresoftware upgrade, read error codes,anddownload/restorethe
EEPROM(chassisalignmentdata).
ChipperCheckIIhardware consists of severalitems. Thehardwareitemsare:
•ChipperCheckII interface box
•InterfaceCables(serialand parallel cables)
•TECI1Adapter Board and Cables
•(2) LegacyAdapter Boards
•ITC222Cable

Chipper Check (CC) vs. Chipper Check II (CCII)
The original interface box worked as designed for chassis of it’s time but as technology
progressed,therewas a needtochangethe interface andalongcameCCII. The difference
betweenCC andCCIIisthetri-level logicofCCIIoverthebi-levellogicofCC. BygoingtoTri-
level,CCIIandamodifiedCC would be able to interface withthemoreadvancedchassis.

5
The modification was simple, just add the daughter board to the original CC interfaces and
theCCbecometri-level logic compatible. AmodifiedCCcircuitboardwill look similar tothe
onebelow:
The new interface CCII and a modified CC incorporates the tri-level logic circuit and are
backwardscompatible.

ThePS2cableisconnectedbetweentheinterface box and adapter board.
There are 3 adapter boards; two legacy adapters and one TECI1. The TECI1 board has
many plugs and a switch. These plugs are for connecting different cables for the different
chassis. Theswitchis forconvergencecommunicationson PTVproducts. Becauseoftheir
separatebuslines,theconvergencecommunications requires a connection separate from
themainI2C bus. Thelargerthree pinconnectorisfor convergenceI2Cbuscommunication.
Inadditionto theTECI1adapter andcables,there arereplacementsforthelegacyadapters.
These replacement cables connect to the TECI1 adapter and provide connection to older
legacysets.

Connecting the Interface Box to the PC
Usingtheparallelcable,locatetheprinterportonthePCandconnectthe25-pinDinconnector
to it. The other end of the printer cable (Centrex connector) connects to the interface box.
Thisistheonly connectionbetweenthePCand theinterfacebox.
Next, connect the serial cable to the interface box and to the appropriate adapter. The
appropriateadapterdependsonwhatchassis isbeingserviced. Do notconnectthe adapter
or cable to the instrument being serviced until instructed to do so by the Chipper Check
software. Eachchassisis different onthesetupand connectionpoint. Informationonsetup
andhookupisfoundinthe Help files of the Chipper Checkprogram.
CCII Install Software
TheChipperCheck softwareisalwayschanging. Tomakesureyouhave thelatestversion,
goto www.thomsonnetwork.net. Under “OrderChipperCheck”,thelatestversionofsoftware
willbeshownandavailable for download. Ifyoualreadyhavethelatest, there is noneedto
downloadthisversion. If not,thendownload thelatestversion.
Oncedownloaded,double clickontheEXEfileandit willselfinstall. Very littleuserinterface
is required for installation. Just follow the on-screen prompts and when done, the PC will
need to be restarted. Restart is necessary because registry information is changed during
theinstalland in orderforthosechanges totakeeffectit requires thecomputerberestarted.
Oncethe PC is restarted, Chipper Check software is ready for use.
Thefirstscreento comeupistheWelcome screen. Thisscreenisthe“are sureyouwantto

Afterthedestinationisselectedtheinstallationprocessisstartedandtheprogressisdisplayed
forreferenceonly bythefollowinggraphic.
When all the files are copied to the destination folder, a screen is displayed indicating the
default port is LPT1. This is the communications port Chipper Check interface uses to
communicate with the PC. If you are already using LPT1 for a printer or other peripheral
device,youmustchangethe INIfiletoindicatewhichporttouse. The onlyoptionsare LPT1,
LPT2,orLPT3. SelectOKto accept the default LPT1 port.

Next is the program group selection. It is recommended you select the default location but
not necessary. This will allow you to customize where you launch Chipper Check program
from.
Thelastwindowdisplayedwillindicatethatchangeshavebeenmadetothecomputerregistry
andthePC willneedtobe rebooted beforethechangeswill takeeffect. Thisisimportant for
Chipper Check operation. Failing to reboot can result in Chipper Check failure. Once the
PCisrebooted,ChipperCheck will function correctly.

CCII Software Start-UP
To start the Chipper Check software, locate the start button on the task bar with the mouse
pointerandclick it. Thenpointto “Programsandlocatethe programgroup“Chipper Check”.
Onceinthe programgroupofChipper Check,locatetheCCII programiconand clickit. This
willlaunchthe ChipperChecksoftware.

More information about the software can be found in the Help files within Chipper Check
Software.
Onescreenfound in allChipperCheckversions isthe“CustomerInformation Screen”. This
screenallows thetechniciantoenteruniqueinformationtogeneratea fileofthestoredvalues
inthemainEEPROM oftheinstrumentbeingserviced. This file canlaterbeused to restore
a corrupt EEPROM for this customer. Since this information is unique to each instrument,
ModelandSerialnumbers are required to proceed past this screen.
Thereare threeoptionsforthistab. One ofthethreehasto becompletedbeforetheprogram
willallowothertabstobe selected. The options are:
1. Openfile
2. Savefile
3. EnterModel andSerialnumbers
If only generic model and serial numbers are used, the technician will not want to save this
information. Saving with generic information can cause the wrong file to be loaded thus
causingadditionalproblemsfor the technician/customer.
The store and open file are optional. By storing the information the technician is creating a
fileforfutureuse. TheopenfileallowsthetechniciantoutilizethesavedfilefeatureofChipper

eliminatedbyrestoringthecustomerfile forthatset. The onlyrequirementwould belocating
thecorrectfile and restoringittothe customersset. TheModeland Serial numberfieldsare
thebestwaytodistinguish betweeninstruments. Becauseof this,themodel andserialfields
needtobefilledintoadvancein the program.

Entering the Service Mode
Duringnormaloperation,newerchassis(CTC195,197,203,210,211,MM101,102,DTV306,
307, and LCOS) are continuously monitoring the I2C bus for an acknowledgment from the
EEPROMthat residesintheChipperCheckinterfacebox. When thesenewerchassisdetect
thattheChipperCheckEEPROMhasbeenconnectedtotheI2Cbus,thechassisautomatically
gointotheService Mode. The chassismustsupplytheI2Cclockduringthis auto-detection,
whichunfortunately,runsapproximately 5timesfaster thantheChipperCheckinterfacebox.
Theinterfacebox suppliestheI2Cclock oncethechassis isintheService Mode. Thespeed
oftheI2Cclockfrom the chassis,combinedwiththe extra resistanceandcapacitanceof the
interfacecablesandtheinterface box,willoccasionally preventtheEEPROMauto-detection
fromworking. Whentheauto-detectiondoesnot work,usethe manualproceduredescribed
below. When the auto-detection doesnotwork,thechassiswill usually shut downandmay
havetobeunpluggedbefore it will power upagain.
