4K HDMI KVM OVER IP Extender

1. Connection instructions

1.1 Connect the HDMI IN Port of the TX to the HDMI output port of signal source/PC over a HDMI cable.

1.2 Connect the HDMI OUT Port of the RX to the HDMI input port of display device over a HDMI cable.

1.3 Connect the 1G LAN Port of the TX to the 1G LAN Port of the RX over a network cable. Gigabit switches need to be inserted between TX and RX when multiplexing

1.4 TX and RX need to be set to the same ID number before use. (Only for HDEX0019M1)

1.5 Supply TX and RX with AC power adapter.

1.6 RS232, IR and other interfaces can be selected as required.

2．RS232 Communication：

2.1 To use RS232 to do communication, the TX RS232 Port Baud rate can be set to 115200. RX RS232 Baud rate can be adjusted between 1200-115200(refer to button function instruction),which need to be matched with the output connected serial port baud rate.

2.2 To use cross-link way for serial port connection, TXD to connect with RXD of the output connected device, the RXD to connect with the TXD of the output connected device, and GND to connect with GND.

2.3 At One to Many Connection mode, TX RS232 can send serial port data to many RX simultaneously and also can monitor many RX RS232.The TX only can receive data of one RX at the same time. When one of the RX send data, the TX will keep communicate with the RX, the other RX have to wait extra 0.2 seconds to get the chance of communicating with the TX after the current RX stopped communication.

3. IR Extend

3.2 To check if the working frequency of the IR remote is under the range of the 30-50HZ.

3.3 To point the IR Transmitter head at the peripheral device location.

3.4 At one to many connection mode, TX will monitor many RX IR interface. The TX only can receive one of the RX IR

 data. When one of the RX send data, the TX will keep communicating with the RX, the other RX have to wait the extra

2seconds to have the chance of communicating after the current RX stopped communicating.

4．Analog Audio Input and Output：

HDEX0020M1 have detected the RX HDMI port have connect the new TV.

7．Other matters needing attention:

7.1 After change the ID set-up, it need to be active by power off and on again.

7.2 If meet exception, the user can try to update the EDID.
