Appendix A: Model 2090 GPIB Command Reference
Model 2090 Multi-Device Controller
*TST?
Description:
Self Test. Prepares the controller to respond with a byte similar to self test
result. Returned messages are always 0.
Devices:
Towers, Turntables
Syntax:
*TST?
Response:
0
The 2090 always reports a passing self test.
Example:
CALL ibwrt (TableUD%, "*TST?")
' Query self test
CALL ibrd (TableUD%, rdbuf$)
' Read response
*WAI
Description:
Wait to Continue. Causes the controller to place execution of the next GPIB
command on hold while there are devices in motion. Once motion has
ceased, the next command is executed normally. While a command is on
hold, additional commands are not accepted. Normal operation will continue
after the command on hold had been executed. Time out of the GPIB bus
must be disabled before execution of *WAI command. The *OPC commands
are a more "program friendly" method of waiting for device motion to stop.
Devices:
Towers, Turntables
Syntax:
*WAI
Example:
CALL ibwrt (TowerUD%, "*WAI")
' Wait for tower motion to
' stop
