Digital Stereo Mixer M-864D

External Control Protocol – TCP/IP

Ver.2.0.0 Dec.2 /2013

■ Summary

The External Control protocol described in this document is designed for use of controlling the M-864D from

a personal computer or remote controller.

This spec sheet applies to the M-864D firmware of version 2.0.0 or later.

Settings that can be controlled are as follows:

Channel Fader Gain

Channel ON/OFF

Line(Stereo) Select

Input Matrix Assignment

Input Matrix Crosspoint Gain

Output Matrix Assignment

Preset Memory Load

Preset Memory Store

LOCAL/UNLOCAL Status Change

Level Meter Status Notification Start/Stop

Auto Status Notification Start/Stop

If necessary, the M-864D’s activation can be checked or setting values read by using the following

commands:

Status request (reading of the M-864D’s setting value)

Status Information

M-864D connection establishment status (output from the M-864D at the time of

connection establishment)

Level Meter Status (output from the M-864D at the time of level meter status changed)

ZM Remote Controller Connection Status (output from the M-864D at the time of ZM

remote controller connection status changed)

Contact Input/Output Make/Break Status (output from the M-864D at the time of

Contact I/O make/break status changed)

[Note]

When connecting the remote controller to the M-864D by way of this protocol, set the M-864D’s Using port

as follows:

TOA Corporation 1/17

Digital stereo mixer M-864D

(Refer; External Control Port Settings of the M-864D software instructions manual.)

Using TCP Port

Ext. Port No.: (Set according to the remote controller to be connected.)

Default Port No:3000

[Note] Meter Port No. is automatically set to Ext. Port No. plus 1;

■ TCP/IP Connection

No. Parameter Description (rules)

1 Connection Path 1 path

2 Data Length Variable-length, The maximum length is 1024 bytes

3 Code Classification Binary

4 Delivery Confirm No handshakes at application layer

5 Resend Control None

6 Priority Control None

M-864D is a TCP server.

TCP Port is always connected.

For the purpose of connection keeping, M-864D performs the following behavior.

Transmitting some kind of data at least once in the last 10 seconds.

When there is the status that for send, M-864D transmits the contents. When there is not it, M-864D

transmits 0xFF only as for 1 byte.

When M-864DP received nothing from a remote controller more than 1 minute, M-864D disconnect

the TCP/IP connection.

■ Command Construction

Command Data length (N) Data 1 Data 2 ……… Data N

Where Command is in the range 80H to FFH. And where Data length and Data are in the range 00H

to 7FH.

The second byte data indicates the number of byte data that follow the second byte data. If received data contains more byte data than the indicated number, those exceeding the number are

abandoned.

When a next command is received, the previous data is abandoned if shorter than the indicated

number.

■ Control Command and Setting Value

Channel Fader Gain (Position)

Set the input and output channel EXT VOL fader gains by position.

For the relationship of position to gain (dB), refer to the Position vs. Gain Table for Fader.

The M-864D transmits changed value data after receiving this command.

91H, 03H, <Channel Attribute>, <Channel Number>, <Position>

00H: Mono In channel

01H: Stereo In channel

02H: Mono Out channel

03H: Rec Out channel

When Channel Attribute=00H: 00H - 07H (Mono In channel 1 – 8)

When Channel Attribute=01H: 00H - 01H (Stereo In channel 1 – 2)

When Channel Attribute=03H: 00H - 01H (Rec Out channel L,R)

00H - 3FH (-INF - +10dB, see the Position vs. Gain Table)

Example of setting Mono In channel 1 EXT VOL fader gain to 0 dB:

91H, 03H, 00H, 00H, 35H

Channel Fader Gain (Step)

Set the input and output channel EXT VOL fader gain positions by the number of steps.

Positions can be varied from the current status by the designated number of steps.

One position varies per step.

The M-864D informs position values changed by step Up or Down.

91H, 03H, <Channel Attribute>, <Channel Number>, <Step>

00H: Mono In channel

01H: Stereo In channel
