1. SUMMARY
The RS-232C protocol described in this document is designed to be used to control the
9000 Series Amplifier from a PC and/or remote controller. This specification applies to the
9000 Series firmware version 3.13 or later.
Settings that can be controlled are as follows:
• Channel fader gain
•
Crosspoint gain (Mixer mode only)
•
Preset memory recall
•
Channel ON/OFF
• Power ON/OFF
•
Tone control (Bass/Treble)
• EQ settings (ON/OFF, Band number selection, Gain setting, Q setting, Center frequency setting)
• Loudness compensation settings
•
Filter settings (High Pass Filter/Low Pass Filter)
•
Input sensitivity setting
• Phantom power setting
Following values can be read from the 9000 Series Amplifier.
• Channel name
When connecting the PC and/or remote controller to the 9000 Series Amplifier using this protocol,
set the 9000 Series Amplifier’s RS-232C port as follows:
Bit rate: 9,600/19,200/38,400/57,600 bps (Select the band rate depending on the
remote controller to be connected.) (See; Operating instructions of the 9000
Series Amplifiers.)
COMMANDLIST, COMMUNICATION EXAMPLES and PARAMETER TABLES are
available at the end of each section of this document.
2. SERIAL PORT SETTING
• 9,600/19,200/38,400/57,600 bps, 8 bits, non-parity, stop bit: 1, non flow control
• Connector: D-sub 9 pins, straight cable
•
Signal line: No.2=TX, No.3=RX, No.5=Ground

3. COMMAND CONFIGURATION
•
• is in the range of 80H to FFH. and are in the
range of 00H to 7FH.
• Data length (N) refers to the length of the subsequent data of Data 1 to Data N.
• If received data contains more byte data than the Data length, these exceeding data are
abandoned.
• If a next command received contains byte data shorter than the Data length, the previous
command is abandoned.
4. TRANSMISSION DATA AFTER COMMAND RECEPTION
When normal data is received, the same data as the reception data is to be transmitted.
Example: 91H, 03H, 00H, 00H, 00H (Reception data)
91H, 03H, 00H, 00H, 00H (Transmission data)
When channel data is received and the data is outside of the range, the data is to be
inverted and transmitted.
Example: 91H, 03H, 00H, 08H, 00H (Reception data)
91H, 03H, 00H, 77H, 00H (Transmission data)
When abnormal data is received, the data is to be inverted and transmitted.
Example: 91H, 03H, 00H, 00H, 6AH (Reception data)
91H, 03H, 00H, 00H, 15H (Transmission data)
When data other than channel data is received and the data is outside of the range, no data
is transmitted.
Example: 91H, 03H, 05H, 00H, 6AH (Reception data)
No response
See section 9. COMMUNICATION EXAMPLES for other transmission data when normal
data is received.

5.3. Preset Memory Recall
Recalls any desired preset memories. 9000Series Amplifier responds with the same data
as that received.
Note:
Settings to be stored in preset memories are referred to as “SCENE” in mixer mode and
“EVENT” in matrix mode.
Preset Memory Recall command cannot be received during power off.
F1H, 02H, 00H, <Preset Number>
<Preset Number> 00H - 1FH: Preset Number 1 - 32
Note: During single channel operation or BGM/PAGE operation in matrix mode

F1H, 02H, 00H, 00H
Example 2: Recalling Preset Memory 2
F1H, 02H, 00H, 01H
Following command is used to terminate "EVENT" in Matrix Mode.
F1H, 02H, 01H, (Event #)
9000 series Amplifier ignores this command in Mixer Mode.
It also ignores this command if the "EVENT" is not activated, or the "EVENT" is BGM
Event.
The ROUTE event using the input channel with priority 8 (BGM event) and the BASE event
cannot be terminated by this command.
To terminate the BGM event or the BASE event, it is necessary to setup the BGM END
event to the unit and activate it.

5.7. EQ Settings
Perform EQ settings (ON/OFF, Band number, Gain, Q and Center frequency) of the
input/output channels. 9000Series Amplifier responds with the same data as that received.
Band number, Gain, Q, and Center frequency cannot be received when EQ is set to OFF.
They can be valid only when EQ is set to ON.
Note: Command cannot be received during power off.
