Set Exposure kV
Description:
The host requests that the firmware set the Exposure kV set-point.
This is the desired voltage output of the supply for the next
exposure.
If the new setting is in the valid range, and the new setting in
combination will the current settings of the other exposure
parameters is valid the unit will respond with a “$ “ following the
command field. If the new setting is valid, but the combination of
the new setting plus the current settings of the other exposure
parameters is illegal the unit will respond with a warning code of 10.
In this case the host will be required to correct the setup problem. If
the setting is invalid / out of range the unit will respond with and
error code of 3 and the previous value of the kV program (set-point)
will remain in effect. If the X-Ray is currently on the unit will return
an error code of 9 (state error). The host is not allowed to modify
exposure settings while the high voltage is on.
Direction:
Host to supply
Syntax:
<STX><10><,><ARG1><,><CSUM><ETX>
Where:
ARG1 = Exposure kV program.
Range = 0-4095 = 0-50,000V
Scaling = 50kV/4095 = 12.21V/Bit
Example:
<STX>10,2047,<CSUM><ETX>
Response:
<STX><10><,><$><,><CSUM><ETX>
Error / Warning Code Responses:
<STX><10><,><E><,><CSUM><ETX>
Where E is:
3 = kV setting is out of bounds
9 = State Error – (Can’t change with X-Ray on)
10 = Invalid Setup Warning
