 +===== OBJECT PIN packet =====
 +The OBJECT PIN packet includes the energy (encoded in the [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|S800 Phillips 7164H ADC]] measured in the S800 OBJ PIN detector. 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 is rarely used.
 + 
 +
 +
 +  * **Packet Length** (self-inclusive)
 +
 +^    A number between 2 and 3    ^^^^^^^^^^^^^^^|
 +| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | X | X | X |

 +  * **Energy**
 +The energy from the Phillips ADC is given by one word:

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

 +===== Galotte packet =====
 +The Galotte packet includes up to five time signals from the Galotte detector. These times are encoded in the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips TDC]]. 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 is rarely used.
 +
 +
 +
 +  * **Packet Length** (self-inclusive)
 +
 +^    A number from 2 to 7    ^^^^^^^^^^^^^^^|
 +| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | X | X | X | X |

 +
 +
 +  * **Time values**
 +The time information for each of the five detector channel is coded in words that look like:
 +
 +^  ^^^ Ch ^  time  ^^^^^^^^^^^|
 +| 0 | 0 | 0 | X | X | X | X | X | X | X | X | X | X | X | X | X |
 +| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
 +
 +where Ch runs from 0 to 4.
