SIS Configurations
and Control
Use SIS commands to configure the DTP HD DA 4K series. This section provides
information about using those commands. Topics include:
•
Introduction to SIS
• Using the Command and Response Table
• Command and Response Table for SIS Commands
Introduction to SIS
The distribution amplifiers can be set up and controlled remotely via Extron SIS commands
that are issued from a host computer running the Extron DataViewer utility or other control
system. The host device can be connected to the mini USB config port on the front panel,
the RJ-45 LAN connector on the rear panel, or the the 3-pole RS-232 captive screw
connector on the rear panel. The protocol for the Remote serial port is as follows:
• 9600 baud • 8 data bit • no parity
NOTE: The wiring in the RS-232 cables crosses over so that the distribution amplifier
transmit (Tx) wire connects with the control device receive (Rx) and vice versa.
Host-to-Distribution Amplifer Communications
SIS commands consist of strings (one or more characters per command field). No special
characters are required to begin or end a command sequence. Unless otherwise stated,
upper and lower case characters can be used interchangeably. Most responses from the
distribution amplifier end with a carriage return and a line feed (CR/LF =
]
), which signal
the end of the response character string. When the switcher determines that a command is
valid, it executes the command and sends a response to the host device.
Distribution Amplifier-Initiated Messages
When a local event such as a change in signal status takes place, the distribution amplifier
responds by sending a message to the host, indicating the status change. No response is
required from the host.
