Read Efficiency – REn
Reads the efficiency of the specified channel. The value returned is
formatted as “nn.n”.
Set Efficiency – SEnxx
Sets the efficiency for the specified channel. The efficiency is set using the
format of “nnn.” Do not send the decimal point. The value must be
formatted to three digits and is adjustable from 000 to 999.
Save Slave Flash Parameters – SF
Saves all calibration constants to flash on all slave boards. The calibration
constants will revert to the last saved values if the counter is reset without
saving.
Read High Voltage – RHn
Reads the high voltage setpoint and readback value from the specified
channel. The return format is “HVnnnnnnnn.” The first four characters are
the setpoint; the last four characters are the readback voltage.
Set High Voltage – SHnxxxx
Sets the high voltage setpoint for the specified channel. The value must be
formatted to four digits and is adjustable from 0000 to 1500.
Read High Voltage Actual Cal – RHACn
Reads the high voltage, actual calibration constant for the specified channel.
The return format is “±n.n.”
Set High Voltage Actual Cal – SHACnxxx
Sets the high voltage, actual calibration constant for the specified channel.
The value must be formatted as “±nn.” Do not include the decimal place.
The range is -99 to +99. After setting any calibration constant, the “SF”
command must be sent to save the values into flash.
Read High Voltage Readback Cal – RHRCn
Reads the high voltage readback calibration constant for the specified
channel. The return format is “±n.n.”
Set High Voltage Readback Cal – SHRCnxxx
Sets the high voltage readback calibration constant for the specified channel.
The value must be formatted as “±nn.” Do not include the decimal place.
