D-901 Digital Mixer
RS-232C Protocol
Ver.2.00 Apr.22/2004
■ Summary
The RS-232C protocol described in this document is designed for use of controlling the D-901 Mixer from a
personal computer or remote controller.
This spec sheet applies to the D-901 firmware of version 2.00 or later.
Settings that can be controlled are as follows:
 Channel fader gain
 Channel ON/OFF
 Input HPF ON/OFF
 Line(Stereo) Select
 Bus assignment
 Crosspoint Gain
 Preset memory recall
If necessary, the D-901’s activation can be checked or setting values read by using the following commands:
 D-901 activation status (output from the D-901 at the time of activation)
 Gate status (transmitted from the D-901 when the gate status changes)
 Status request (reading of the D-901’s setting value)
When connecting the remote controller to the D-901 Mixer by way of this protocol, set the D-901’s RS-232C
port as follows:
 Mode: Remote
 Bit rate: 9,600/19,200/38,400/115,200 (Select according to the remote controller to
be connected.)
(Refer; RS-232C Port Settings of the D-901 instruction manual.)
■ Serial Port Settings
 9,600/19,200/38,400/115,200 bps, 8 bits, non-parity, stop bit: 1, no flow control
 Connector: D-sub 9 pins, straight cable
 Signal line: No. 2=TX; No. 3=RX; No. 5=Ground
■ 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 fader gains by position.
For the relationship of position to gain (dB), refer to the Position vs. Gain Table for Fader.
