2.7 USING THE 9009’
s
GPIb INTERFACE
The 9009 has a standard 24-pin GPIB connector with metric locking studs.
The 9009’s GPIB Interface is factory set to primary address 4. As part of the
self test at power turn-on time, the 9009 blinks a binary display of its GPIB
address on is diagnostic LEDs. The bit weights are:
RDY TALK LSTN SRQ ERR
16 8 4 2 1
The GPIB Interface has access to the same SCPI parameters as does the Eth-
ernet Interface. The default GPIB and serial settings are listed in Table 1-3.
Compare the serial settings against the settings on your slave Modbus device.
Adjust the serial settings so both units have the same settings.
2.7.1 GPIB Configuration Method
This method uses an interactive utility such as ICS’s GPIBkybd, Agilent IO
Connection Expert or National Instruments’ MAX to query and change the
current settings using the SCPI commands in Table 3-3. GPIBkybd can be
installed from the Support CD or downloaded from ICS’s website.
1. Connect the 9009 to a GPIB Controller.
2. Run your utility program and find the 9009 (Default is address 4).
3. Do an *IDN? query to read the IDN message to verify communication
with the 9009.
4. Select the appropriate SCPI command from the SCPI Command Tree
in Table 3-3 for the parameter you want to query or change. Put a
question mark after the command to query its current setting. Send
the command with a value to change the setting.
5. Repeat Step 5 for each parameter you want to query or change.
6. When done, send the unit a *SAV 0 command to save the new set-
tings.
