FOX3 T 201 Transmitter • SIS Configuration and Control 19
Simple Instruction Set Control
Host-to-Unit Instructions
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
transmitter executes the command and sends a response to the host device. All responses
from the transmitter 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.
Device-Initiated Power-Up Message
When the device completes its start‑up, it issues the following message to the host:

Error Responses
