Connecting to the VP-725N 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
(

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.
