3. External Connection
COM-2PD(PCI)H, COM-4PD(PCI)H
35
In the case of COM-4PD(PCI)H
When using a COM-4PD(PCI)H, an alternative to connecting an external device directly to the
connector on the board is to use a connection conversion cable.
Using the 9-pin D-SUB Connector Conversion Cables
Use a PCE37/9PS connection conversion cable (purchased separately) to connect to external devices
after dividing into four 9-pin D-SUB male connector channels.

CAUTION
The SG lines for CH1 to CH4 of the option cable are not connected to the cable shielding. However,
the frame of each connector is connected to the shielding. This means that the cable shielding is
connected to the body of the PC via the frame of the interface connector.
Note that the option cable is not a twisted-pair cable.
