DESCRIPTION
Modify one channel voltage (Chan/Mainframe)
(12)
Set values
. Must follow a T=0, T=2, T=7,
or T=12
Modify all 3.3 kV channel voltage (Mainframe
select)
Read true voltage of addressed channel
True voltage (actual rear panel output in volts)

(9)
HV ON/OFF Switch
(9)
HV ON/OFF Status
Restore addressed channel
Preset all 3.3 kV channel (Mainframe select)
if high voltage is off
Read demand value of addressed channel
Demand value (in volts)
Status request
(11)
Failed channel response
Read demand value of all 32 channels
Response Identifying Pod complement
ENABLE/DISABLE finished (T=11) response
Finished response
