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

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.

Use cable suitable for use with 9-pin D-SUB connectors

(purchase separately) with the two divided connectors.

When using an RS-232C interface, different cables are

required depending on the type of device to which you are

connecting (computer or modem, etc.). Check the

requirements of the external device and select either a

straight-through or crossed (null modem) cable as appropriate.

If special treatment of the signal lines in the connector is

required, ensure that this is done in accordance with the

specifications.
