5.1 Connecting a PC
You can connect to the VS-401USB via an RS-232 connection using, for example,
a PC. Note that a null-modem adapter/connection is not required.
To connect to the VS-401USB via RS-232, connect the RS-232 9-pin D-sub rear
panel port on the VS-401USB unit via a 9-wire straight cable (only pin 2 to pin 2,
pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub
port on your PC.
