UL rack mounting guidelines
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the switcher on a rack.
1. Elevated operating ambient temperature — If the
equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the
rack environment may be greater than room ambient
temperature. Therefore, install the switcher in an
environment compatible with the maximum ambient
temperature (Tma = +122 °F, +50 °C) specied by Extron.
2. Reduced air flow — Install the equipment in the rack so
that the amount of air ow required for safe operation of
the equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack
so that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Consider equipment nameplate ratings
when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
Rack mounting instructions
For optional rack mounting, do not install the rubber feet.
Mount the switcher to a rack shelf as follows:
1. If rubber feet are installed on the bottom of the unit,
remove them.
2. Mount the switcher on the rack shelf, using two 4-40 x
3/16" screws in opposite (diagonal) corners to secure the
switcher to the shelf.
3. Install blank panel(s) or other unit(s) to the rack shelf.

Setting Up RS-232 Communication
The SW4 3G HD-SDI switcher can be congured and controlled
by SIS (Simple Instruction Set) commands via the switcher’s
RS-232 port. This port is used to connect the switcher to a host
or external controlling device, such as a computer or control
system, that can generate the proper command codes and
recognize the switcher’s responses.
Wire the RS-232 connector as shown below.
RS-232 connector wiring
The serial port has the following RS-232 protocol:
• 9600 baud
• 1 stop bit
• No parity
• 8 data bits
Using Simple Instruction Set (SIS) Commands
Host-to-switcher communications
3-2
The Extron Simple Instruction Set (SIS) commands consist of
one or more characters per eld. No special characters are
required to begin or end a command character sequence. When
a command is valid, the switcher executes the command and
sends a response to the host device. All responses from the
switcher 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.
SW4 3G HD-SDI • Serial Communication
Switcher-initiated messages
When a local event such as a front panel operation or error
condition occurs, the switcher responds by sending a message to
the host. The switcher-initiated messages are listed below:
(c) Copyright 2008, Extron Electronics, SW4 3G HD-SDI, Vx.xx]
The switcher issues the copyright message when it rst powers
on. Vx.xx is the rmware version number.
Inn]
The switcher sends the Inn message whenever the selected
input is changed using the front panel buttons. “n” is the input
number.
Error responses
When the switcher receives a valid SIS command, it executes
the command and sends a response to the host device. If
the switcher is unable to execute the command because the
command is invalid or it contains invalid parameters, the
switcher returns an error response to the host. The error
response codes are:
E01 – Invalid input channel number (out of range)
E06 – Invalid input channel change (auto-switch active)
E10 – Invalid command
E13 – Invalid parameter
Timeout
Pauses of 10 seconds or longer between command ASCII
characters result in a timeout. The command operation is
aborted with no other indication.
