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 present at all. The CPU module handles the current-loop interface, driven by a 24V source. The ND-120, on the other hand, drives the current-loop interface from a 12V source, and uses the V+ side of these signals directly as the RS-232 interface.
