Description of messages used in the communication between TCS and DC.

Messages from TCS to DC
Message	Meaning
AZABxxx	Absolute movement to azimuth xxx
AZR+xxx	Relative movement (+xxx or −xxx degrees)
AZR−xxx
PARK	Movement to the PARK position
STOP	Stops dome movement if it is in motion
¿AZ?	Requires present azimuth, status, EEPROM content, motor consumption.
¿ST?
¿EE?
¿CO?
AOFF	Auto messages disabled
A_AZ	Auto azimuth, auto consumption, auto zero cross messages enabled.
A_CO
A_ZE
CPARxxx	TCS sends new values for park position, zero cross position, zero margin constant, inertia constant.
CZERxxx
CZEMxxx
CINExxx
Messages from DC to TCS
FIN!xxx	Last command executed, dome stopped at azimuth xxx.
¡ZE!xxx	Zero cross detected at azimuth xxx
¡AZ!xxx	Present azimuth, status, EEPROM contents, consumption. These messages are sent in response to ¿AZ? ¿ST? ¿EE? ¿CO? or as automatic information, if the corresponding option is enabled.
¡ST!
¡EE!
¡CO!
PAR!xxx	Confirmation of new values for park position, zero position, zero margin or inertia constant, sent by TCS through commands CPARxxx, CZERxxx, CZEMxxx and CINExxx.
ZER!xxx
ZERM!xxx
INE!xxx
ERR!	Error message. The type of error is codified in the <argument> field.
