"Standard" Wiring from the MDC Box to the Machine

A "standard" machine (i.e. Fanuc, Heidenhain etc.) will use one of the following cable specs:

**Cable from MDC Box to MC** (machine requires RTS/CTS handshake).
MDC box (DE-9 female)		Machine (DB-25 male)
3	brown	3
2	red	2
7	blue	5
8	white	4
5	black	7
		6,8,20 linked on machine end

**Cable from MDC Box to MC** (machine uses XOn XOff handshake).
MDC box (DE-9 female)		Machine (DB-25 male)
3	brown	3
2	red	2
5	black	7
		4,5 linked on machine end 6,8,20 linked on machine end

**Cable from MDC Box to MC** (machine uses XOn XOff handshake)
**MDC box powered by the Fanuc RS-232 24V supply on pin 25**.
MDC box (DE-9 female)		Machine (DB-25 male)
3	brown	3
2	red	2
5	black	7
9	orange	25
		4,5 linked on machine end 6,8,20 linked on machine end

Note this assumes a Fanuc control with a working 24V supply on pin 25 of its serial port. To use this option it is necessary to open the MDC box and move the input fuse and connect a link. Contact CNC for details. The maximum current you can draw from the RS-232 line is limited so you can only power the MDC box, a single Moxa port and a barcode reader from this source.
