+===== Focal Plane PIN-stack packet =====
+In some experiments, a stack of PIN detectors is included in the detector setup. The S800 DAQ can accommodate up to five different PIN detectors. Their energy are encoded in the [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|S800 Phillips 7164H ADC]]. Note that for most of the experiments, this packet is empty (i.e. it only includes the packet-length and packet tag) because this detector stack is rarely used.

+===== LaBr packet =====
+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).
