Console terminal
- Console terminal
- Terminal 1, connected to the CPU in the computer. Communication and fault-finding are usually carried out on the console terminal.
Connections
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.
On the older split CPU/MMS version of the ND-100, the RS-232 interface may be handled by the MMS (if a RS-232 interface is present at all on these). The CPU module itself handles the current-loop interface, driven by a 24V source. In later systems, the ND-120 CPU provides both current-loop and RS-232 compatible signals, in a simple way by driving the current-loop from a 12V source. This enables it to repurpose the same signals for both RS-232 and current-loop.
