Escient MP-100 manual Command Responses

FIREBALL-MP INSTALLATION & USER’S GUIDE - M21101-

All commands will cause one of the following response numbers to be issued. Some commands, such as database commands will also send back additional responses that contain more detailed information.

Command Responses

COMMAND		RESPONSE NUMBER	RESPONSE DESCRIPTION
	GROUP
01		01	OK
01		02	Bad Command Structure
01		03	Empty Library or Bad Range
01		04	Wrong Number of Command Arguments
01		05	Invalid Subcommand
01		06	Invalid Command
01		07	Not Available During Standby (deprecated)
01		08	Requested data not available
01		09	External control command not yet implemented (future)
01		10	Not Available at This Time

Response Format: ESCX01xx, where xx = Command response

Response 07 has been deprecated due to the new auto-on function. Whenever a valid command is received (with two exceptions), the sys- tem will automatically enter the “on” mode, if it is in standby. A client may still handle response 07, but it is no longer sent from the host for any reason.

Response 10 will be sent when a normally valid command is sent to the host, but it cannot be processed due to the system’s mode. For ex- ample, a database play will not be processed while the system is in setup or options mode, autobuilding a changer, etc. Note that a keypress command will never return this response, as even audio transport keys (play, stop) have alternate functions in various modes.

Unsolicited status events can be sent to report the state changes of the Escient products. There are two currently defined message levels:

5 - track changes, and 10 - all (including 1-second playing time updates). Clients are registered at level 5 by default. Clients may change their message level using the ESCX7002 command. See the control commands section for instructions on how to resister and unregister for unsolicited status event levels.
