Installation

Step 1: Setup the transmitter
Connect a source device to the transmitter:

Connect the supplied power adapter to the DC IN port of the transmitter and a wall socket. Once the transmitter is connected to power the LED indicator lights on the source selection switch will be white.
Plug an HDMI cable or USB-C cable into transmitter’s corresponding connector.
Plug the cable into the Source Device.

Step 2: Setup the receiver
HDTV set connection with receiver

Connect the HDMI cable to the HDMI OUT jack of the receiver and to your HDTV set (or an HD projector).
Connect the supplied power adapter to the Micro USB port of the receiver and a wall socket. When it’s connected to power the Power LED indicator will be white.

Step 3: Boot up the transmitter and receiver

After the power cord is plugged into the electrical outlet, the Wireless Conference Room Hub will be turned on and link established automatically.
When transmitter power is unplugged, receiver will enter Standby mode (POWER LED of receiver is lit in red) when link is dropped for over 10mins.
When receiver is in Standby mode (Receiver POWER LED is lit in red), and transmitter is powered, the transmitter will wake up the receiver and automatically to establish a link.
During the warm-up period, the POWER LED will blink white until the signal link between the transmitter and the receiver is established. It will take around 15 ~ 20 seconds for boot up and link establishment if the operation is in normal condition.
Ensure your TV set or projector is in “HDMI input” mode and is powered on.
If all operation is normal, the POWER LED and INFO/CHANNEL LED will be solid white.

Please refer to the below form containing detailed LED indicator and OSD description of transmitter / receiver:

LED/OSD Behavior

The power LED will be solid white when the unit is powered on.
The source LED will be solid white when the source is selected. (The default setting of the source is HDMI, as indicated by the solid white HDMI LED.)
Press the source button to switch to the input source; the switch sequence is: HDMI USB TYPE-C1 USB TYPE-C2 HDMI.
If there is signal (HDMI 5V , USB TYPE-C VBUS)in the source input:
The TX unit will send the CEC message “TEXT VIEW ON” to turn on the TV set.
The TX unit will then send the CEC message “ACTIVE SOURCE” to switch to the selected source of the TV set .
For the “auto switch”:
If the input source A (maybe HDMI or USB TYPE-C1 or USB TYPE-C2) is selected originally, and then the signal (HDMI 5V or USB TYPE-C) is detected on source B (maybe HDMI or USB TYPE-C1 or USB TYPE-C2). The input source will be auto switched from source A to source B.
The TX unit will send the CEC message “TEXT VIEW ON” to turn on the TV set.
The TX unit will then send the CEC message “ACTIVE SOURCE” to switch to the selected source of the TV set .
If there is no signal to the source input: the TX unit will not send a CEC message.
If there is no signal to the source input and if the end user plugs in the source cable and a signal is received:
The TX unit will send the CEC message “TEXT VIEW ON” to turn on the TV set.
The TX unit will then send the CEC message “ACTIVE SOURCE” to switch to the selected source of the TV set.
If there is a signal to the source input and if the end user presses the source button to switch the source without a signal present: the TX unit will not send a CEC message, and the TV (display unit) will display a black screen.
If there is a signal to the source input and if the end user then unplugs the source cable, the TX unit will not send a CEC message, RX will send 480P black screen and the OSD will display which input source is selected : “HDMI”, “USB Type-C-1”, or “USB Type-C-2”.

Step 4: Mounting the receiver to the Wall

Mark pilot holes by holding mounting plate (2) on wall.
Drill pilot holes from markings.
Insert the supplied anchors (3) into the wall.
Mount receiver (5) to mounting plate with the two supplied (4) screws.
Align the four holes that had been used for the pilot holes to the four anchors in the wall.
Use the four supplied screws (1) to screw into the anchors. Do not over tighten.
