Setting the GPIB port address

The default GPIB address is 15. You can specify a different address.

To set the address of the GPIB port directly on the generator:

1. Locate the rotary switches on the back of the generator between the RS-232 port and

the GPIB port. These are accessible through the ventilation slots. There are two rotary

switches: the one on the left configures the value of the tens digit and the one on the

right configures the value of the ones digit.

2. Set the rotary switches first the value of the tens switch and then the value of the ones

switch to the desired value.

3. Hold down the DCS key, and then cycle the power to the generator. The port is set to

the new address.

Note: A normal power cycle will not update the memory to the new switch settings.

To set the address of the GPIB port using the command line:

1. Establish a terminal session with the generator

2. (Optional) Enter the following command to check the current address:

GPIB?

3. Enter the following command:

GPIB address

When the address is changed with the GPIB command, the change takes place as

soon at the command is issued.

The new address setting will be maintained until 1) the address is changed with another

GPIB command, 2) the unit is re-initialized with an INIT command, or 3) the unit is

re-initialized because the power-up self test found corrupted data in battery-backed

system memory. In cases 2 and 3, the GPIB address will revert to the address set on

the GPIB address switches if the unit has them, or to 15 if the unit does not have GPIB

address switches.
