Séura S1 RS-232 Protocol
Command Structure
A Séura S1 RS-232 command consists of a header, an identifier, an optional separator and value and a terminator.
A command shall contain no spaces between fields.
A command always begins with an “&” (ampersand, no quote marks).
A command is always 9 bytes long including the carriage return. If the value field uses less than 3 bytes the missing
characters shall be filled with “*” (asterisk, no quote marks).
Timing
General timing constraints:
• Wait 10 seconds after power ON command before sending next command.
• Wait for response (ACK message) before sending next command
•
Minimum 2 seconds delay before resending a command if no response received.
• Minimum 500ms delay between commands.
• Minimum 5 seconds delay after sending 20 commands.
RS-232 Communication Parameters
Command Structure
Baud rate is configurable from the OSD Service Menu.
Default baud rate is 38400.
Default access password for Service Menu is 1 2 3 4
Examples for identifiers: PWR, BAS, SRC
Separators:
: (colon) Value change. Value given will replace existing value
Example: &SRC:USB will change the input to USB
? (question mark) Get current value
Introduction
The Séura S1 Series LCD displays can be controlled with RS-232 commands from a host (computer, system controller such as Crestron, Control4,
Savant, etc.). This document describes the details of this protocol.
RS-232 Communication Protocol
This section describes the communication protocol used to control the Séura S1 Series
remotely.
Note: Some commands will generate OSD feedback.
Note: IR Commands will generate serial feedback.
Connect a Host to the S1
Connect the S1 to the host controller using a crossed (null modem) serial cable or a straight-through cable with a null modem adapter.
