When using the CCU-78F/25M connection conversion unit
Use a CCU-78F/25M connection conversion unit (purchased separately) to connect to external devices after dividing into eight 25-pin D-SUB
male connector channels.
This method has the following features.
- The unit can be fitted to a DIN rail using a separately purchased ADP-1 DIN rail adapter.
- The unit can be fitted to a wall or similar using screws.
- By connecting an external power supply, the unit can output a power supply from the 25-pin D-SUB connector.
Use a separately purchased 25-pin D-SUB connector cable to connect from the eight individual connectors.
◆ C on ne ct i ng dir e ct ly t o t he po rt c o nn ec to r
If connecting an external device directly from the connector on the board, use a CN5-D78M or equivalent connector.

Screw nut: UNC#4-40(inch screw)
The connector used for COM8-(PCI)H has a wide interpin space and is highly reliable.
In the case of a PC with a narrow slot opening, a gap might be created as wide as the
thickness of the sheet metal of the PC when an external cable is connected, preventing
the connector from being fitted properly. If the thickness of the sheet metal is less than
1.5mm (typically about 1.0mm), simply tighten the adjusting screw located on the side
of the connector to install it properly. The connector should function without a problem.
