	On the ND-100, the console terminal connects through the CPU/MMS port A. The pinout is in many ways similar to the 4- and 8-terminal interface port, but with the difference that only pin Ac7-Ac12 goes to DB-25 pin 2-7, while Aa7-Aa12 goes to DB-25 pin 15-20. This would be the same as just crimping on a female DB-25 connector on the appropriate part of the flat-cable. Like the 4- and 8-terminal modules, a powered current-loop interface is also provided on DB-25 pins 15-16 (Rx) and 17-18 (Tx) in this case.
