A comma nd uses a 2- byte ASCII format, starting with Line Field (LF), which is followed by machine ID, and ending with Carriage Return ( CR).

For infor mation about machine ID, see the section 3-2 Machine ID.

A comma nd is followed by a byte string, which c onsists of data ranging fro m 0 bytes (if the command includes no data) to 9 8 bytes, maximum.

For detailed information about data, see each of the sections explaining co mmands. Note that capital letters are used for “A to F” for commands that use 0 to 9 an d A to F as data values.

Command examples

Example 1: Sending the PLAY c ommand to the controlled device with the machine ID=0

When the controlled device is in the stop or ready state, t he PLAY com mand starts playing the

controll ed device.

The PL AY command is [12] and sent in the follo wing format.

2.6.Command Se quence

In most cases, the controlled device does not send an ACK command in re sponse to a transport control command or data preset command that is sent from an external controller.

The controlled device sends a ret urn command in response to a data sense command t hat requests the controlled device to return the controlled device's preset data values.

If the controlled device switches from one state to another - from stop state to playback state, for exa mple, or if an error occurs, the con trolled device sends a com mand to notify the external controller about the state transition. Examp les of command sequences are shown b elow.

Make sure that com mands are sent at a minimum of 20-millis econd interva ls.

Examp le 1: Using a transport control of the controlled device (e.g. playback)

When entering the playback state after receiving the playback c ommand, the controlled de vice sends the CHA NGE STATUS command.

The controlled device does not send an ACK command in response to this c ommand.

	Command			Status of the controlled
External co ntroller			Controlled device	device
				STO P
PL AY		->
		<-	CHANG ED STATUS	Sent when the controlled device
				ente rs the playback state

Examp le 2: Presetti ng data (e.g. p itch control data)

When re ceiving the PITCH CONTR OL DATA PR ESET command, the contro lled device se ts the pitch control data. The controlled device does not send an ACK command in response to this co mmand.

	Command			Status of the controlled
External co ntroller			Controlled device	device
PITCH CONTR OL DATA				Set the pitch control data to
PR ESET		->		-1.0%
(preset to -1.0 % )

Examp le 3: Requesting currently set data (e.g. pitch control d ata)

When re ceiving the PITCH CONTR OL DATA PR ESET (Sense command, the controlled device sends th e set pitch co ntrol data.

	Command				Status of the controlled
External co ntroller		Controlled device			device
PITCH CONTR OL DATA	->
PR ESET (Sens e)
	<-	PITCH CONTROL D ATA RETURN

Example 4: Performing the next o peration after checking the status of the c ontrolled deviice

When switching from one mode to another, the controlle d device sends the CHAN GED STATUS command. Then, in response to the CHANGED STATU S command, the MECHA S TATUS SEN SE command is sent from the external controller so that the new oper ation mode ca n be checked.

The following table shows that recording is started on the external controller after the controlled device’s rec ord ready mode is confirm ed.

	Command			Status of the co ntrolled devic e
External controller			Controlled device
				STO P
RECORD (Reco rd Ready)		->
		<-	CHANG ED STATUS	Sent when the c ontrolled device
				ente rs record ready mode
M ECHA STATUS SENSE		->
		<-	MECHA STATUS RETURN	Ret urns the current status
				information (record ready)
RECORD (Reco rd)		->
		<-	CHANG ES STATUS	Sent when the c ontrolled device
				ente rs recording mode

Command details

The commands, data and Machine ID given here are ASCII characters.

Commands are 2-byte characters, the Machin e ID is a 1-byte character a nd Data are each 1-byte c haracters. The specifications for take and project numbe rs that this un it can handle are as follow s. If a number is specified for a n item that does not exist, however, the command will be treated as invalid.
