Set Exposure Settings
Description:
The host requests that the firmware change the exposure settings
of kV, mA, exposure time and filament large/small. Note: This
command changes the same parameters as the individual “Set
Exposure” commands. It can be used in place of or along with
these commands, or not used at all. Using this command allows for
additional parsing and expanded error code response over using
individual commands but otherwise performs the same function.
This command should only be used when the unit is in 3-Point
Mode. If you are in 2-Point mode the command will not change the
exposure settings.
Direction:
Host to supply
Syntax:
<STX><50><,><ARG1><,><ARG2><,><ARG3><,><ARG4><,><C
SUM><ETX>
Where: (ARG# in ASCII format)
ARG1 = Exposure Time (in milliseconds)
ARG2 = kV program (0-4095 = 0-50,000V)
ARG3 = mA program (0-4095 = 0-200mA)
ARG4 = Large/Small Filament = 1 – Large, 0 - Small
Example:
<STX>50,4095,4095,4095,1,<CSUM><ETX>
Response:
<STX><50><,><$><,><CSUM><ETX>
Notes:
The maximum allowed exposure time is the smaller of 12000msec
or the value specified by the Tube Table. The tube table value is a
function of kV, mA, Filament and HSS Speed. The default Minimum
allowed exposure time is 5 milliseconds.
kV program is 50kV/4095 = 12.21V/Bit
mA program is 200mA/4095 = 0.04884mA/Bit
