The crossover cable (type "C") can skip up to 4 16-point output
blocks to connect units.
If more blocks should be skipped to supply power to an input block,
use cable type "B".
2.5 Connection to input/output connector
The input/output connectors of the Main units (Connector type)
conform to MIL-C-83503.

1) Compliant connectors (commercially available connectors)
Use a 20-pin (1-key) socket connector conforming to MIL-C-
83503.
Confirm in advance that the connectors do not interfere with other
parts including connector covers.
2) Input/output cables (available from Mitsubishi)
Input/output cables with attached connectors are available.
