Preparing the Lambda Wheel detector system

Switch ON the power supplies for the HELIX chips
Set the default delays in the DPG (use: tune_dpg)
Reset the HLCU (use: resethlcu)
Set the default delays in the HLCU (use: tune_hlcu)
Set the default parameters in the HADC (use: tune_hadc)
Set the default parameters in the HELIX chips (use: tune_helix)

Until a reliable procedure has been identified, the status of the HELIX chips should be checked by the following:

axher2> hadccmd -x
 Version 1.22/09 of HIGZ started
Open returns: 0

<HADC> clear
cleared

<HADC> zero
cleared memories

<HADC> flags
cleared flags

<HADC> acq 1
acquisition mode is on

<HADC> acq 0
acquisition mode is off

<HADC> data 0
read 2052 words

<HADC> dis mem all

<HADC> quit

axher2>

This should produce four plots with the typical HELIX patterns. Repeat using tune_helix until this is the case.
