INTRODUCTION
1
Atlona Technologies’ AT-COMP-44M is one of the most innovative Component Matrix switchers
with Stereo Audio on the market. The AT-COMP-44M has 4 individual Component Video (RCA)
inputs with Audio and 4 individual outputs. Because it is a matrix switch, any input can
routeto any output; and the same input can routeto all outputs or any other combination. This unit
is ideal for connecting sources including: (VCRs, Camcorders, Video Game Consoles, DVDs,
Satellite Receivers, Set Top Boxes, etc.) to desired displays such as: (HDTV, LCDs, Plasma
Monitors, Video Projectors, etc.) Selection of inputs can be achieved manually through the Front
Panel, an Infrared Remote Control unit or RS232 control. Easily Switch with awless and
crystal-clear distribution of all HDTV video formats up to 1080p as well as audio signals. With
these attributes, the AT-COMP-44M is a great matrix switch capable of handling High Denition
Television applications.

Before making any connections to the AT-COMP-44M Observe the following:
Mains voltage supply must matches the label on the supplied plug-Pack (+/- 10%)
Power switch is OFF
All system grounds (earth) must be connected to a common point.
Avoid powering equipment within a system from multiple power sources that may be separated by large
distances
Connect all audio video sources and destination equipment
Power up all sources
For each destination output select the appropriate input source by usingthe front panel input 1-4 select
buttons, the supplied IR remote control or through the RS 232 serial communications port.
Upon power up, the switcher will return to its last used setting before powered down.

2. RS232
The AT-COMP-44M can be controlled via the RS-232 serial control port to allow for interfacing to a PC, or
a similar third party control system.
The serial communication parameters are 9600 baud, 8 bit, No Parity and 1 stop bit - this is often referred
to as 9600 8N1.
When the unit recognizes a complete command it will perform the requested action - there is no delimiter
character required.
The unit does not send out a message when a value is changed from the front panel or by IR control. If the
unit needs to be controlled via the front panel in addition to the RS232 control, you should regularly poll
the unit status to ensure the control system accurately relate the current settings.
3. PROTOCOL COMMANDS
To Switch Inputs to Outputs
SBI0XO0Y- Where X is Output Number (1~4) and Y is Number (1~4)
Unit will respond with
SBUD0XOY - Where X is Output Number (1~4) and Y is Input Number (1~4)
Example : Send Input 4 to Output 3
SBUD04O3-Send
SBI04O03-Rcvd

RS-232 SERIAL INTERFACE

Note: Turning the unit System Power Off over RS232 will distinguish the LED display leaving only the Power
Switch LED on. The Video and Audio outputs will also mute. While the unit is turned off by RS232 it will
continue to accept and act upon switching commands. For example, if the unit is in the OFF Mode
(via RS232) and you send a command to switch an input to an output, that route will complete and the
video and audio will now appear on that channel only. The front panel LED for that particular output will
also show the input selected (for that single output channel only). The remaining LED’s will remain off
and video and audio outputs muted. The unit will still return status and change messages in response
to commands sent while in Power Off state. A hard reset command (SBALLRST) will return the unit to
normal operation and also unlock the front panel.
1. POWER OFF MODE
SBSYSMOF - Place system into Standby (Soft Power Off)
SBSYSMON - Bring unit out of Standby (Soft Power On)
Unit will respond with
SBALOFAK - Unit is in Standby
SBALONAK - Unit is no longer in Standby
Example : Put Unit in Standby (Soft Power)
SBSYSMOF - Send
SBALOFAK - Rcvd
2. FRONT PANEL LOCK
Note: Hard resetting the unit will unlock the Front Panel controls.
SBSYSMLK - When front panel is locked, changes can only be made by RS232
SBSYSMUK- Front Panel Unlock
Unit will respond with
SBSYSLOK - Front Panel has been Locked
SBSYSULK - Front Panel has been Unlocked
Example : Lock Front Panel Buttons
SBSYSMLK - Send
SBSYSLOK - Rcvd
3. UNIT RESET
SBALLRST - Reset every output to Input 1 Unit will respond with
SBRSTACK - Unit has reset each Output to Input 1
Example : Reset all outputs to Input 1
SBALLRST - Send
SBRSTACK - Rcvd
