To connect the instrument to the IEEE-488 bus, line up the cable connector with the connector on the
rear panel. Install and tighten the screws securely, making sure not to overtighten them. The following
figure shows the location of the connector.Connect any additional connectors from other instruments
as required for your application. Make sure the other end of the cable is properly connected to the
controller. You can only have 15 devices connected to an IEEE-488 bus, including the controller. The
maximum cable length is either two meters (6.5 feet) multiplied by the number of devices or 20
meters (65.6 feet), whichever is less. Erratic bus operation may occur if you ignore these limits.
Primary address
The Series 2600B ships from the factory with a GPIB primary address of 26. If the GPIB interface is
enabled, it momentarily displays the primary address on power-up. You can set the address to a
value from 0 to 30, but do not assign the same address to another device or to a controller that is on
the same GPIB bus (controller addresses are usually 0 or 21).
To set or check the primary address from the front panel:
1. Press the
MENU
key, then select
GPIB
, and then press the
ENTER
key or the navigation wheel
.
2. Select
ADDRESS
, then press the
ENTER
key or the navigation wheel
.
3. Use the navigation wheel
to set the primary address to the appropriate value, then press the
ENTER
key or the navigation wheel
.
4. Press the
EXIT (LOCAL)
key twice to return to the normal display.
To set the primary address remotely:
gpib.address = address
To set the primary address remotely to 20:
gpib.address = 20
Note that changing the GPIB address takes effect when the command is processed. Any response
messages generated after processing this command are sent with the new settings. If command
messages are being queued (sent before this command has executed), the new settings may take
effect in the middle of a subsequent command message, so care should be exercised when setting
this attribute from the GPIB interface.
Terminator
When receiving data over the GPIB, the instrument terminates messages on any line feed character
or any data byte with EOI asserted (line feed with EOI asserted is also valid). When sending data, it
appends a line feed character to all outgoing messages. The EOI line is asserted with the terminating
line feed character.
General bus commands
General commands are commands that have the same general meaning, regardless of the
instrument (for example, DCL). The following table lists the general bus commands.
