How to Control the SRP-X700P from External Equipment
REMOTE RS-232C Terminal
Use of this terminal enables you to control the SRP-X700P from an external
controller.
The specifications of the communication protocol are shown below.
Terminal shape : D-sub 9-pin, male
Electrical specifications : Conforms to RS-232C standard
Recommended cable : Multi-core shielded cable for data communication
Cable length : 15 m or less
Communication format
Baud rate : 9600 bps
Bit length : 8 bits
Stop bit : 1 bit
Parity : ODD (odd number)
REMOTE PARALLEL Terminal
The REMOTE PARALLEL terminal enables the SRP-X700P to be
remotely controlled with a simple circuit connected externally to
this terminal.
INPUT terminal
You can set the functions of the respective terminals from the
PARALLEL INPUT FUNCTION setup box in the REMOTE
screen of the supplied SRP-X700P Manager software.
All faders and sound volume controls can be controlled from a
remote location by connecting a variable resistor as shown, in the
range of 0 to
–
∞ dB.
You can perform the following operations by adding a make contact.
• Input selection of LINE 4 system
• Muting
• Scene recall
• Sound volume adjustment (Up/Down)
• Controlling the AV equipment connected to the CONTROL S
terminal
• Power-ON/STANDBY selection of a projector
OUTPUT terminal
The turning ON conditions of the respective pins of the OUTPUT
terminal can be set from the following.
• Input selector state of LINE 4 system
• Turning ON the OVER and
–
∞ indicators
• Turning ON the scene recall button
• Generation of the Power-ON/STANDBY command of a
projector
You can select the ON conditions from the PARALLEL OUTPUT
FUNCTION setup box on the REMOTE screen of the supplied
SRP-X700P Manager software.
