the instruction via RS232 interface.

The connections between GFG-3015 and computer are as follows:

Connect one end of a RS232 cable to the computer.
Connect the other end of the cable to the RS232 port on the GFG-3015.
Turn on the GFG-3015.
Turn on the computer.

The RS232 connection testing

If you want to test whether the RS232 connection is working or not, you can
send a command from computer. For instance, using a terminal program send
the query command (uppercase)
*IDN?

following format:
GW,GFG3015,V.1.00

If you do not receive a proper response from the GFG-3015, please check if the
power is on, the RS232 configurations are the same on both sides, and all cable
connections are active.
