 +===== 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.

 +The energy from each PIN detector encoded in the Phillips ADC is given by FIVE consecutive words with the following format:  ​

 +| 0 | 0 | 0 | X | X | X | X | X | X | X | X | X | X | X | X | X |

 +

 +here **Ch** is the Phillips ADC channel reserved for each of the PIN detector (from 10 to 14). The energy words is sent by the Filter as long as **energy** is greater than 0.
