and PlenumVault options are also available for wall or plenum ceiling mount applications (for
installation instructions, see the installation guides for each system).
WARNING: Structural ceiling failure could cause serious injury or death. Check the
structural ceiling to ensure that it can handle a load four times the weight of the final
setup.
AVERTISSEMENT : Un défaut dans la structure du plafond pourrait provoquer des
blessures graves voire mortelles. Vérifier la structure du plafond afin de vous assurer qu’il
peut supporter une charge quatre fois supérieure au poids de l’installation finale.
Possible switcher mounting locations include:
• Table top, cabinet, or shelf (attach the four provided rubber feet to the bottom of the unit)
• Under a desk
• Mounted to a wall with an Extron WMK 160 or USFM 100 WallVault Wall Mount Kit

SIS Configuration and Control
This section provides information on how to configure the VoiceLift system using Extron
Simple Instruction Set (SIS) commands. It provides a list and descriptions of the available
commands. Topics include:
• Overview
• Host to Receiver Communication
• Commands and Responses
• Command and Response Table for SIS Commands
NOTE: The VoiceLift System can also be configured using the Extron Product
Configuration Software (PCS). For full details about using PCS, see the PVS 407D
PoleVault Digital Switcher User Guide available online at www.extron.com, or the
PCS help file, embedded in the PCS software.
Overview
The VLR 302 receiver can be controlled via a host computer that is connected to the USB
control port on the VLR 302 receiver. Commands can be sent from the computer using a
communication software program such as Extron DataViewer. SIS commands are available
for various functions, such as obtaining information and status for the VLR 302 ports,
controlling relay functions, pairing, and resetting the VLR 302.
Host to Receiver Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the VLR 302 recognizes a valid
command, it executes the command and sends a response to the host device. All responses
from the receiver to the host end the character string with a carriage return and a line feed
(CR/LF = ]). A string is one or more characters.
Error Response
When the VLR 302 receives a valid SIS command, it executes the command and sends a
response to the host device. If the receiver is unable to execute the command because the
command is invalid or contains invalid parameters, it returns the following error response to
the host:
E13 – Invalid value (the number is out of range)
Timeout
A pause of 10 seconds or longer between command characters results in a timeout. The
command operation is aborted with no other indication.
