Interface Box Diagnostic Tests
Chipper Check II software incorporates several diagnostic tests to verify communication
between the interface, adapter, and PC. To do all the tests requires the interface be connected
to the PC and one adapter or cable / adapter combination be connected to the interface.
Most of the circuitry inside the interface box can be tested without any adapters being
connected. Running the ‘Check data lines’ and the ‘Detect EEPROM’ routines checks 75%
of the interface circuitry. The remaining circuitry is tested by using external jumpers and the
#212121 adapter board (used with CTC195/197/203) or the TECI1 and Cable adapter. The
components required to do all diagnostic tests are:
· Interface box and cables
· Adapter 212121
· Jumper Cable +
OR
· TECI1 Adapter
· Cable +
To start the diagnostic tests, click on the Diagnostic tool bar and select the test you want to
perform.
Check data lines: There are two I

C data lines, going from the interface box to the computer.
During the data line test, the data lines are toggled high and low by configuring tri-state buffers
and internally setting the data lines high or low inside the interface box. If this test fails, it
