APPENDIX A
Here follows a short description of the V793 status array bits and of the CAENET communication data
packet exchanged with the Controller.

/*The message sent from the CAENET Controller has the format: */

/* MASTER IDENT. 1 */
/* CRATE NUMBER XX */
/* OPERATION CODE: */
/* byte high byte low */
/* 0 0 -> module identification */
/* 0 1 -> set V793 status */
/* 0 2 -> get V793 status */
/* */
/* Code 0 1 is followed by these bytes: */

/* ADC[0] status[0] -> en_brd 8..1 */
/* ADC[1] status[1] -> en_brd 16..9 */
/* ADC[2] status[2] -> A764_O-E V791_O-E C en_brd 19..17 */
