Description
Cd (Clock- and data wiring test):
When the wiring of clock line and data line is ok,
the display shows “Cd 11”. Display of “Cd 10”
means that the clock line is o.k. but the data wires
are false (wrong polarity) and "Cd 01" indicates a
problem with the clock lines.
With master mode, only the data lines are subject
of this test.
Cd (Clock- and data function test):
The next test generates clock and data signals and
feeds them directly into the rear terminals.
Therefore please remove the encoder connection.
“Cd iO” says that clock and data interface are all
right. and all other displays indicate a problem
with the SSI interface circuit.
