 ==== Commands ==== ==== Commands ====
-The only PEC command is "PEC" it has one argument. This argument can be **"ON", "OFF", or "Train"**. Anything else will be ignored with no indication from TCSng. If you turn the PEC on you will set the **PECSTAT** condition to **3 (WAITING)** and the PEC mode to **1(ON)**. When the index pulse is found both the condition and the mode will report **1 (ON)**. Turning the PEC off will lose the index. Turning the PEC on when it is already on will set the PEC condition to **3 (WAITING)** essentially turning off corrections until the next index pulse. +The only PEC command is "PEC" it has one argument.

- +Commanding the PEC to **TRAIN** will make the current PEC corrections unavailable. Only someone with root access to the TCSng computer will be able to recover it.
