*R
- Reset Power-On
TYPE System
EXECUTION
Immediate
SYNTAX
*R
Power-on reset. Equivalent to a hardware reset.
DESCRIPTION
The Reset Power-On (
*R
) command has the same effect on the unit as removing and re-applying power. All
buffer data and channel configurations are erased. Meanwhile, the IEEE 488 bus commands Device Clear (
DCL
)
and Selected Device Clear (
SDC
) do not have this effect. They clear only the command input buffer, the output
queue, and any pending commands.
Note: Because the Reset Power-On (
*R
) command performs a full power-on reset, 3 or 4 seconds are required
before you can communicate with the unit. A total of at least 5 seconds is required before normal
operations can take place.
Note: Issuing the Set Power-Up Configuration (
*S
) command
*S1
and then power-cycling the unit, or issuing
the Reset Power-On (
*R
) command will cause any previously defined configuration to be irrevocably lost.
However, the calibration factors for the unit and its slaves will remain intact.
EXAMPLE
PRINT#1,"OUTPUT07;*RX"
‘ Restore power-on settings to the unit
SLEEP 4
‘ Wait 4 seconds to restore communication
WHILE (S% and 4) = 0
PRINT #1, “SPOLL07"
INPUT#2,S%
‘ Keep checking the Serial Poll response of the unit until it is ready
