VP-731 - Connecting the VP-731 13

5.1 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 (

Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a

crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be

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 (

Figure 5)—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.
