Using verbose mode
SSH connections to a FOX3 device can be used to monitor for changes that occur on the
device, such as SIS commands from other SSH sockets or a serial port. For a SSH session
to receive change notices from the device, the SSH session must be in verbose mode 1 or

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
receiver executes the command and sends a response to the host device. All responses

When the scaling receiver receives a valid SIS command, it executes the command
and sends a response to the host device. If the scaling receiver is unable to execute the
command because the command is invalid or it contains invalid parameters, the scaling
receiver returns an error response to the host. The error response codes are:
