1. RS-232 Serial Interface
RS-232 serial interface connect a PC or Control System
Pin RS-232 Denition
1 - Not used
2 Tx Transmitter
3 Rx Receiver
4 - Not used
5 GND Ground
6 - Not used
7 - Not used
8 - Not used
9 - Not used
2. RS-232
Atlona Technologies’ switcher can be controlled via the RS-232 serial control port to allow for interfacing to a
PC, 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 reects the current settings or similar third
party control system.
3. Commands
To Switch Inputs to Outputs
SBI0XO0Y- Where X is Output Number (1-2) and Y is Input Number (1-4)
Unit will respond with
SBUD0XOY- Where X is Output Number (1-2) and Y is Input Number (1-4)
Example : Send Input 4 to Output 2
SBI04O02-Send
SBUD04O2-Rcvd

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 con-
tinue 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.

CONNECTION AND INSTALLATION
PC RS232 Control
HDMI Player 2
HDMI Player 3
HDMI Display 1HDMI Display 2
Note: If connecting the outputs to both displays and AV receivers, the audio output will only be stereo due
to the display are only able to handle PCM or Stereo Audio through HDMI inputs. If all devices are AV re-
ceivers then multi-channel audio such as Dolby TrueHD and DTS-HD can be output. Likewise, the switch-
er will also look at the resolution of all at panels connected and output the resolution of the lowest display.
For example: If three TV’s are 1080p and one is 720p, the output to all TV’s will be 720p
To achieve 1080p across all displays, no matter what their resolution is, take a look at the AT-HD560 and
AT-HD550 both are up/down scalers which can take any resolution and turn it to whatever the displays native
resolution is.
