NAV E 501 and NAV E 101 Encoders • SIS Operation 61
SIS Operation
The encoder can be remotely controlled, monitored, or configured using the following:
•
A user-defined string consisting of SIS commands (see below)
NOTE: SIS commands cannot be issued directly to the encoder, but are issued
via an Extron control system on the AV network using a process known as
“encapsulation”.
• Extron Toolbelt or a control system constructed using either Global Configurator Plus,
Global Configurator Pro, or Global Scripter (see
Control System on page 57)
• Built-in HTML pages (see HTML Operation on page 16)
This section provides guidance on operation of the encoder via a string of commands and
lists the SIS commands, including:
•
Host-to-Encoder Communications
• Encoder-Initiated Messages
• Encoder Error Responses
•
Using the Command and Response Tables

SIS Command and Response Table
Host-to-Encoder Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
encoder executes the command and sends a response to the host device. All responses
from the encoder to the host end with a carriage return and a line feed (CR/LF =
] ), which
signals the end of the response character string. A string is one or more characters.
Encoder-Initiated Messages
When the encoder completes its start-up, it issues the following message to the host:
