Set Exposure mAs and mA
Description:
This command is valid only when mAs+mA mode is selected via
the set Mode 3-Point / 2-Point / mAs + mA command. (Command =
55)
The host requests that the firmware change the exposure settings
by specifying kV, mAs, mA and filament. The exposure time will be
dependent of the mAs and mA selected.
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
mAs + mA Mode. If you are in 2-Point or 3-Point, mode the
command will not change the exposure settings.

SUM><ETX>
Where: (ARG# in ASCII format)
ARG1 = kV program, 0-4095 = 0-50,000V
ARG2 = mAs program, 0 to 6000 = 0 – 600mAs (0.1mAs / bit)
ARG3 = mA program, 0-4095 = 0-200mA
ARG4 = Large/Small Filament = 1 – Large, 0 - Small
Example:
<STX>71,4095,4095,4095,1,<CSUM><ETX>
Response:
<STX><71><,><$><,><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.
