Digital Speaker Processor DP-SP3
External Control Protocol – TCP/IP
Ver.1.0.0 Aug.20 /2013
■ Summary
The External Control protocol described in this document is designed for use of controlling the DP-SP3 from
a remote controller.
This spec sheet applies to the DP-SP3 firmware of version 2.0.0 or later.
Settings that can be controlled are as follows:
Gain
Matrix Assignment
Matrix Crosspoint Gain
Attenuator
Mute
Preset Memory Load
Preset Memory Store
Level Meter Status Notification Interval
Auto Status Notification Start/Stop
If necessary, the DP-SP3’s activation can be checked or setting values read by using the following commands:
Status request (reading of the DP-SP3’s setting value)
Status Information
DP-SP3 connection establishment status (output from the DP-SP3 at the time of
connection establishment)
Level Meter Status (output from the DP-SP3 at the time of level meter status changed)
Contact Input Make/Break Status (output from the DP-SP3 at the time of Contact Input
make/break status changed)
Using TCP Port
Control Port No.: 3000
Level Meter Status Port No.: 3001

■ 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
DP-SP3 is a TCP server.
TCP Port is always connected.
For the purpose of connection keeping, DP-SP3 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, DP-SP3 transmits the contents. When there is not it, DP-SP3
transmits 0xFF only as for 1 byte.
When DP-SP3 received nothing from a remote controller more than 1 minute, DP-SP3 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.
