IR use guide

1. IR passback
   IR blaster extension cable should plug into the IR-out port of TX (Transmitter) of this extender matrix, and the IR receiver extension cable should plug into the IR-in port of the RX (Receiver) of this matrix extender. The emitter of IR blaster should as close as possible to the IR receiver window of the signal source device.

2. IR remote control
   Using the IR remote controller to set/select the channel of this HDMI Extender Matrix.

Button control
There is a “TX ID” on TX unit, and there are both ” RXID” and “TX connected” on the RX unit. Each of them consists of two Nixie tubes and two buttons (beside the Nixie tube), the left button controls the value of the left Nixie tube, and the right one to control the value of the right Nixie tube. The value of each Nixie tube is from 0 to 9, each button is pressed at a time, the number is added one value. For example, the existing value of TX ID is “00, and press the left button once, also press the right button once, then the value of TX ID is changed to” 11″ .When the value of “TX connected” on the RX unit is as same as the value of “TX ID” on the TX unit, a connection built between the TX and RX units.

• Short press: Press to set IGMP group and display the setted value. Product switches automatically to the corresponding IGMP group 5 seconds after the press.
• Long press: Press and keep 3 seconds to reset the product.

Computer software control use guide

1. Access to network
   Connect your PC/computer with the off-the-shelf IGMP Ethernet switch via a single network cable

2. PC/computer setting
   Change the PC/computer’s IP to 192.168.1.xxx (xxx can be 0 to 255), which as same as the IP segment of TX unit and RX unit.

3. Web operation
   Open application program “HDbitT E-Matrix Control center” ,it displays the interface as Figure 1 ( Download from the website: http://www.hdbitt.com /download-matrix/).

IP setting
TX and RX have their own default IP address, TX’s IP is 192.168.1.238, and RX’s IP is 192.168.1.239. Generally, it is no need to change the device IP address, as the system can work normally even though multiple TX units and multiple RX units connected into the system with their default IP address.

1. If IP setting is really needed, please follow up the operation as Figure 2 (here make an example of TX’s IP setting only, RX’s setting is the same as TX’s)
2. Device scanning and setting (here make an example of TX’s setting only, RX’s setting is same as TX’s) *Click button “Start Scan” the scanned result shows as Figure 3
3. Device Name setting as Figure 4
4. Device channel (TX ID) setting as Figure 5
5. Click button “Update” , new configuration saved
6. Pre-operation mode editing, show as Figure 6

Operation mode selection setting
Follow up Figure 7, Click button “Select Mode” , to choose the mode needed.
