5.3 Connecting to the VP-725NA 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 (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.
