6.3 Connecting to the VP-725XLA via RS-232
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 (pin
2
to pin
3
, pin
3
to pin
2
, and pin
5
to pin
5
) 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

2 A display mode in which a frame consists of two separate fields with the first field consisting of odd horizontal lines and the
second field even horizontal lines
