What is Chipper Check II (CCII)?
Chipper Check II is an advanced interface box that provides communication between the TV
2
set being serviced and a personal computer. The interface converts the I
of the TV to serial communication used by the PC. With the Chipper Check software, the PC
is able to control certain functions of the TV and perform some alignments.
Other functions of CCII are software upgrade, read error codes, and download / restore the
EEPROM (chassis alignment data).
Chipper Check II hardware consists of several items. The hardware items are:
• Chipper Check II interface box
• Interface Cables (serial and parallel cables)
• TECI1 Adapter Board and Cables
• (2) Legacy Adapter Boards
• ITC222 Cable
C bus communication

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, there was a need to change the interface and along came CCII. The difference
between CC and CCII is the tri-level logic of CCII over the bi-level logic of CC. By going to Trilevel, CCII and a modified CC would be able to interface with the more advanced chassis.
4
The modification was simple, just add the daughter board to the original CC interfaces and
the CC become tri-level logic compatible. A modified CC circuit board will look similar to the
one below:
Daughter Board
The new interface CCII and a modified CC incorporates the tri-level logic circuit and are
backwards compatible.
Chipper Check II Interface
There are two types of interface boxes, the modified CF002 and CF003. A tri-level interface
is the only one that is compatible with current chassis.
The Purpose of the interface box is to allow a PC to be connected to the TV set via adapters
and cables.
T o make the connection to the PC, a parallel printer cable is used. This cable connect s to the
parallel port on the PC and the Centrex end connects to the interface box.
5
The PS2 cable is connected between the interface 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. The switch is for convergence communications on PTV products. Because of their
separate bus lines, the convergence communications requires a connection separate from
the main I2C bus. The larger three pin connector is for convergence I2C bus communication.
In addition to the TECI1 adapter and cables, there are replacements for the legacy adapters.
These replacement cables connect to the TECI1 adapter and provide connection to older
legacy sets.

Connecting the Interface Box to the PC
Using the parallel cable, locate the printer port on the PC and connect the 25-pin Din connector
to it. The other end of the printer cable (Centrex connector) connects to the interface box.
This is the only connection between the PC and the interface box.
Next, connect the serial cable to the interface box and to the appropriate adapter. The
appropriate adapter depends on what chassis is being serviced. Do not connect the adapter
or cable to the instrument being serviced until instructed to do so by the Chipper Check
software. Each chassis is different on the setup and connection point. Information on setup
and hookup is found in the Help files of the Chipper Check program.
CCII Install Software
The Chipper Check software is always changing. T o make sure you have the latest version,
go to www .thomsonnetwork.net. Under “Order Chipper Check”, the latest version of software
will be shown and available for download. If you already have the latest, there is no need to
download this version. If not, then download the latest version.
Once downloaded, double click on the EXE file and it will self install. V ery little user interface
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
the install and in order for those changes to take effect it requires the computer be restarted.
Once the PC is restarted, Chipper Check software is ready for use.
The first screen to come up is the Welcome screen. This screen is the “are sure you want to
install” screen. Options are OK or Cancel. OK will start the installation and Cancel will stop
the installation.
If your updating a previous version of CCII, the install software will automatically remove any
previous version of Chipper Check.
7
The next user input required screen asks for the “Destination Directory”. This is the directory
in which you want the install program to store the Chipper Check files. It is recommended you
accept the default location but is not necessary .
After the destination is selected the installation process is started and the progress is displayed
for reference only by the following graphic.
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, you must change the INI file to indicate which port to use. The only options are LPT1,
LPT2, or LPT3. Select OK to accept the default LPT1 port.
8
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.
The last window displayed will indicate that changes have been made to the computer registry
and the PC will need to be rebooted before the changes will take effect. This is important for
Chipper Check operation. Failing to reboot can result in Chipper Check failure. Once the
PC is rebooted, Chipper Check will function correctly .

CCII Software Start-UP
T o st art the Chipper Check software, locate the start button on the task bar with the mouse
pointer and click it. Then point to “Programs and locate the program group “Chipper Check”.
Once in the program group of Chipper Check, locate the CCII program icon and click it. This
will launch the Chipper Check software.
The first time CCII software is run, the Servicer Information entry screen is the first screen to
appear. Once filled in, this screen will not reappear . The Servicer Information entry screen
allows the Servicer to personalize their version of Chipper Check.
Options are:
• Fill in all information and click on the “OK” button. This will prevent this entry screen
from being displayed again.
• Select “Cancel” button to bypass with out entering any information. Doing so will allow
future starts of Chipper Check to display this entry screen.
• The “Help” button launches a pop-up window displaying help information.
Depending on the version of software, the main screen displayed after the Servicer Information
screen is the start screen of Chipper Check. In the following example (V ersion 1.86), there
are several options depending on what chassis is being serviced.
10
More information about the software can be found in the Help files within Chipper Check
Software.
One screen found in all Chipper Check versions is the “Customer Information Screen”. This
screen allows the technician to enter unique information to generate a file of the stored values
in the main EEPROM of the instrument being serviced. This file can later be used to restore
a corrupt EEPROM for this customer. Since this information is unique to each instrument,
Model and Serial numbers are required to proceed past this screen.
There are three options for this tab. One of the three has to be completed before the program
will allow other tabs to be selected. The options are:
1. Open file
2. Save file
3. Enter Model and Serial numbers
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
causing additional problems for the technician / customer.
The store and open file are optional. By storing the information the technician is creating a
file for future use. The open file allows the technician to utilize the saved file feature of Chipper
Check at a latter date. In other words, if the technician saved the file the first time in for repair
and later the set needed the EEPROM replace, the alignment process would be almost
11
eliminated by restoring the customer file for that set. The only requirement would be locating
the correct file and restoring it to the customers set. The Model and Serial number fields are
the best way to distinguish between instruments. Because of this, the model and serial fields
need to be filled in to advance in the program.
