DMS2.5 has total 10 DI ports. However, actually used DI
ports are Ch1 and Ch2, and the rest of the ports (Ch3~Ch10)
are for additional functions. Therefore, make sure to
connect Ch1 or Ch2 when using it.
For DO, Ch1 and Ch2 are currently used inside of DMS2.5.
Ch9 and Ch10 are reserved in case of need. Therefore you
can only use Ch3~Ch8.
