CTC175, 176, 177, 186 & 187 Setup Procedure
Connecting the Chipper Check interface box to the chassis requires the following:
1. Interface Box
2. Parallel Printer Cable
3. Interface Cable 212118
4. Adapter Board 212121
The only function Chipper Check can perform on these chassis is initializing the EEPROM to
factory settings.
1. The set MUST be OFF and UNPLUGGED when initializing the EEPROM.
2. You must determine if the set has a Motorola or ST microprocessor (U3101) U3101 is
marked with either ST or Motorola. If the IC is a Motorola ground pin 1, if the IC is
marked ST ground pin 2. Retain this ground while the EEPROM is being initialized.
Once reinitialized, remove the ground before returning the set to normal operation.
3. Prior to initializing the EEPROM, an external 5 volt supply and a 1K resistor must be
connected per the diagram on the next page. DO NOT apply the external 5 volts until
after the chassis is selected in the Chipper Check software. If 5 volts is applied before
the chassis is selected a NO COMMUNICATIONS error may result.
