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.

Page 3 of 24

• 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

5. CONTROL COMMAND AND SETTING VALUE

5.1. Channel Fader Gain

5.1.1. Channel Fader Gain - Position setting

Set the input and output channel fader gains to a fixed value position.

Note: Command cannot be received during power off.

9000Series Amplifier responds with the same data as that received.

5.1.2 Channel Fader Gain - Step Up/ Step Down

Set the input and output channel 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.

9000 series Amplifier informs position values changed by commands.
Position values are shown in POSITION V/S GAIN TABLE.
Values are 1dB step under -40dB, and 2dB step under -60dB.

The 9000series Amplifier informs position values changed by Step Up or Down.
