6.2.43 Computer-to-GPIB Serial Poll Procedure
NOTE
This is a GPIB only command!
6.2.43.1 Description
The read status command indicates if long term operations have ended.
The response to this command is a single character. This character should be
interpreted bit-by-bit. The status byte can be read by querying the Controller serially.
This can be done at any time by the computer; although the Controller never initiates
a Service Request (SRQ).
6.2.43.2 Response
The Least Significant Bit (Bit #0) gives an indication of the Targets-Wheel (RAD)
status:
• A value of "0" means that the wheel is rotating,
• A value of "1" means that the wheel has reached its final position.
Bits #1, #2, and #4 are useable on the CTS-1 only.
Bit #3 gives temperature status: a value of "1" means that the set point temperature
has been reached.
All other bits are set to "0".
(LSB) 0 Target Wheel "0" = Rotating
1 RAD SYNC "1" = SYNC was found
2 CTS-1 Stage "0" = moving
3 Temperature Stable "1" = READY
4 CTS-1 Stage Home "1" = Home
5 --- Always "0"
6 Service Request Always "0"
(MSB) 7 --- Always "0"
