These inputs are TTL active low and will be activated when set to 0V.
2
All inputs are the same in terms of input range (+/-12); D13 can be used as Index B.
3
Pins 6, 7, 25 and 26 represent Index B, Home B, Reverse Limit B and Forward Limit B. The states
of these inputs are mapped to inputs 7, 6, 5 and 4 respectively. Standard input interrogation commands
can be used to read these inputs (TI, MG@IN[n]), as well as the TS and MG@LFB or MG@LRB
switch commands.
