External Connection; Using The 9-Pin D-Sub Connector Conversion Cables - Contec COM-2PD-LPE User Manual

3. External Connection

This chapter describes the interface connectors on the board.
Check the information available here when connecting an external device.
In addition to connecting directly to the connector on the board, you can also connect external devices
via a distribution cable or distribution unit.
- Connecting directly to the port connector.
- Using a distribution cable
When using a COM-2PD-LPE, 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 PCE44/9P2S connection conversion cable (purchased separately) to connect to external devices
after dividing into two 9-pin D-SUB male connector channels.
- Connector used
44-pin D-SUB, male connector
Thumb screw :
UNC #4-40 (inch screw)

Connection conversion (Option)
Connection Conversion Cable (44M→9M x 2, 250mm)
CAUTION
The SG lines for CH1 – CH2 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.
