8.4.3.1. Test column
This function is used to verify the functionality of the column UP /
DOWN end run microswitches.
The display will be updated as follows:
C O L U M N T E S T
I D L E 0 0 0 a b
Using the column up/column down keys verify that the last two
digits change status:

a = 1, column up

b = 1, column down.
8.4.3.2. Test input ports
This function is used to carry out diagnostics at low level of the various
input signals of the CPU board A5. It may be used, for example, to verify
the limit switches without necessarily moving the axes but manually
activating the optical sensor / microswitches.
The display will be updated as follows:
T E S T I N P U T P O R T S
R y 7 6 5 4 3 2 1 0
where:

Ry = selected port code (R4, R5, R6, R7)

76543210 = logic status of the port inputs.
NOTE:
The following table describes the correspondence between the displayed
figures and the corresponding input signal. The digits are numbered from
7 to 0. The 7 digit corresponds to the character furthest to the left on the
display, while digit 0 corresponds to the character furthest to the right.
