SCUBA-2 Systems Review Multi-Channel Electronics. Hilo, Hawaii June 19-23, 2006. MCE Overview. Each MCE reads signals from a 41 ×32 pixel sub-array. 4 readout cards (RC) that each read 8 output lines through 14-bit 50MHz ADCs.

In addition to ‘Science Data Mode’ we have a number of readout modes to help diagnose performance.
Combinations of these options are possible.
Question: Can the Data Pipeline handle any of these?
MCE shuts itself down only if:
MCE status prior to auto-shutdown is recorded into an EEPROM.
AC/DC unit shuts down if over temperature is detected.
