7.2 Connectors J4/J5
Two 26-pin headers, J4 and J5, bring out connections from the board's six counter channels to external field wiring. J4 is
used for counter channels 0-2 and J5 for channels 3-5.

7.2.1 Counter Signals
Each counter channel has six input signals on its header connector: A+, A-, B+, B-, X+, and X-. The header also has power
and ground pins that can be used to supply operating power to external devices such as incremental encoders. The following
table details the header pins that are available for each channel and their recommended usage.
