+ | If you see this kind error message when starting the DAQ with the hodoscope in the trigger (Ext. 1 in ULM gui), check the voltages on the crate which holds the hodoscope shaper modules. If they are not at the correct values, follow this procedure: | ||
+ | - Turn crate off | ||
+ | - Unplug both shapers (for both hodoscopes). Just pull them but don’t fully remove the cards. | ||
+ | - With shapers unplugged, turn crate on and check voltages | ||
+ | - With crate on, firmly push one of the shapers in. | ||
+ | - Push second shaper in | ||
+ | - Verify crate voltages | ||
