Connecting a PC
You can connect to the unit via a crossed RS-232 connection, using for example, a
PC. A crossed cable or null-modem is required as shown in method A and B
respectively. If a shielded cable is used, connect the shield to pin 5.
Method A (
)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin

connected) to the RS-232 9-pin D-sub port on the PC.
Note: There is no need to connect any other pins.

Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
Method B (
)—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem adapter
to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all
nine wires for a full connection of the D-sub connector. Because the null-modem
adapter (which already includes the flow control jumpering described in Method A
above) only requires pins 2, 3 and 5 to be connected, you are free to decide
whether to connect only these 3 pins or all 9 pins.
