| + | The LaBr packet includes the energy (encoded in the [[S800 USB DAQ data format#Tag 0x4300: FERA module for plastic scintillator energies|FERA LeCroy module]]) and times (encoded in a Phillips TDC) from up to four LaBr detectors. | ||
| + | Note that although there is a specific EVB tag for that Phillips TDC (0x7187), this module is currently not included in the S800 electronics. As a result, the data packet is empty (i.e. it only includes the packet-length and packet tag). | ||
