Set the GPIB address
The default GPIB address is 16. You can set the address from 1 to 30 if it is unique in the system.
This address cannot conflict with an address that is assigned to another instrument or to the GPIB
controller.
GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an
address of 21.
The instrument saves the address in nonvolatile memory. It does not change when you send a reset
command or when you turn the power off and on again.
To set the GPIB address from the front panel:
1. Press the MENU key.
2. Select Communication.
3. Select the GPIB tab.
4. Set the GPIB Address.
5. Select OK.
You can also set the GPIB address using remote commands. Set the GPIB address with the SCPI
command :SYSTem:GPIB:ADDRess or the TSP command gpib.address.
RS-232
You can communicate with the instrument using RS-232 if a KTTI-RS232 communications accessory
card is installed in the instrument.
The card provides six independently configurable digital input/output lines that can be used to control
external digital circuitry, for example, a handler that is used to perform binning operations. The digital
I/O port is a standard female DB-9 connector. You can also use these lines for triggering. The
instrument can generate output trigger pulses and detect input trigger pulses.
