GPIB Communications
The GPIB communications page allows you to monitor and test
communications to various devices on the GPIB.
GPIB Devices
General Purpose Interface Bus (IEEE 488) provides a means for
several devices to communicate data through a parallel communica-
tions bus. Each device on the bus has a device address.
To identify what devices are present on the bus, click Poll.
Talk/Listen
A GPIB bus may contain only one controller device; all other
devices are talkers, listeners, or talker/listeners. AD007 serves as a
controller device any time an active GPIB control session is open.
To send a command string to the specific address of a device on the
bus, do these steps:
1. Click Poll to identify what devices are on the GPIB.
2. Select the specific address of the device from the pull-down
menu of polled addresses.
3. Enter the command in the box provided.
4. Click Send.
Network Connections
A network client control application can leave control sessions alive
on the AD007 adapter. The adapter cannot automatically clear
inactive connections. To clear all active and inactive network control
sessions, select VXI-11 Reset.
