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.

2.2 FEATURES

FIGURE 4-3. CONTROL SOURCE DEVICE

CHAPTER 5: RS-232 CONTROL

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.

CommWatch.exe

FIGURE 5-2. CONTROL INTERFACE

Set the COM number, bound rate, data bit, stop bit, and parity bit parameters correctly, and the commands are ready to send in the Command Sending Area.

5.2 RS-232 COMMAND FORMAT

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.

2. The unit ID of the splitter, x = 0-9/A-F
3. Fixed value

FIGURE 5-1. COMMAND FORMAT

1. 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.

    A["AB"] --> B["①"]
    C["AC"] --> B
    D["BC"] --> E["②"]
    F["XX"] --> G["②"]

Fixed value

The four X represent four HDBaseT outputs.

X=0, OFF

X=1, ON

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.

DEFAULT L.RES H.RES EDID

FIGURE 6-1. EDID DIP SWITCH

TABLE 6-1. EDID DIP SWITCH SETTINGS

SWITCH STATUS DESCRIPTION
L. RES	The splitter reads EDID from all connected displays, and then the source device will automatically obtain the EDID that contains the lowest resolution.
DEFAULT Reset to the default EDID to distribute 4K @ 30 Hz video.
H. RES	The splitter reads EDID from all connected displays, and then the source device will automatically obtain the EDID that contains the highest resolution.

NOTE: When the four displays have the same resolution parameter, the source device will obtain the EDID with priority from HDBT 1 to HDBT 4.
