   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:

(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.
