2.1 INTRODUCTION
The HDBaseT Video Splitter, 1 x 4, 4K UHD, Smart EDID accepts a single HDMI input and splits it into four HDBaseT outputs. The splitter
is designed with an HDMI loop out, which is intended to cascade to additional units. It supports video resolutions up to 4K@60Hz and all
HDMI audio formats. It can extend 1080p signals on each output to a distance up to 229 feet (70 meters) and 4K signals to a distance up
to 131 feet (40 meters) over a single CATx Ethernet cable. It supports the Power over HDBaseT (PoH) feature, which allows the compatible
receivers to be powered from the splitter over the Ethernet cables. It supports bidirectional IR and RS-232 pass-through and loop output.

The splitter and compatible receivers feature RS-232 ports to transmit RS-232 signals from computer to control far-end third-party
devices by using 3-pin to DB9 cable and a RS-232 control software, such as CommWatch. Compatible receivers must be able to
communicate at 2400, 4800, 9600, 19200, 38400, 57600, or 115200 baud.
5.1 RS-232 CONTROL SOFTWARE
Installation: Copy the control software file to the computer connected with the splitter.
Uninstallation: Delete all the control software files in corresponding file path.
BASIC SETTINGS
First, connect all input devices and output devices needed, then connect it with a computer that has RS-232 control software
installed.
Double-click the software icon to run this software. Here take the software CommWatch.exe as example. The icon is shown next.

5.2 RS-232 COMMAN D FOR MAT
Each unit in a cascaded system must have a unique ID if using RS-232 control. Using the ID PRESET DIP switch, set the ID. For
example, the unit ID of the first splitter is set as 0, and then the second is set as 1 and so on.
The system supports RS-232 pass-through control; if the RS-232 IN port is connected to a PC, and the others are connected to
third-party devices, these third-party devices can be controlled by following these steps:
1. Send the command in the format below to select the unit to receive commands.
FIGURE 5-1. COMMAND FORMAT
2. Send the specific control command data (HEX) to control the selected third-party devices. For specific commands, refer to the
user manuals of the devices you want to control. For example, send A5 A5 A5 5A 01 WW 02 0A 01 00 RR to mute the third-party
devices.

SWITCHING ON/OFF HDBASET OUTPUTS
The HDBaseT outputs can be controlled by sending commands. Connect the PC to the RS-232 input, and then according to the next
steps to switch on/off HDBaseT outputs.
Take the unit ID of 2, for example.
1. First, send F5 BB 6F 20 to select the unit to receive commands.
2. Second, according to the format shown, send the command to switch on/off HDBaseT outputs.
Fixed value
The four X represent four HDBaseT outputs.
X=0, OFF
X=1, O N
If the HDBT 1 port needs to be turned on, other ports are closed, send the command AB AC BC 10 00.

The Extended Display Identification Data (EDID) is used by the source device to match its video resolution with that of the
connected display. By default, the source device obtains its EDID from the first connected display. However, since the displays with
different capabilities can be connected to the splitter, the EDID DIP switch can be used to set the EDID to a fixed value.
