2BTWG-PRO1Wireless AV Transmitter and Receiver

1 Wireless AV Transmitter and Receiver 2 Product Description It is a standard H.265/H.264 codec TCP/IP HD transmission product, and its main feature is that the same RX with different TX can be used in 1080P/4k@30HZ and other application scenarios! When upgrading the project, you only need to replace the transmitter to realize the transmission image from 1080P upgraded to 4k, which greatly saves the cost of upgrading the project. In addition to supporting HDMI audio and video transmission, this product also has a TX local loop out, IR back control, 3.5mm audio input and output and other features for users to choose. Please choose different styles according to the actual needs. This series of products are divided into network cable version（ProA）, fiber optic version（ProB）, network cable + wireless version（P roC）of the three transmission modes of the product, to provide users with more convenience! This manual only briefly describes the network cable + wireless version(（ProC）), wired version please refer to the corresponding manual. Product category Note: When transmitting wirelessly, the designer connects up to 4 receivers (RX) to one transmitter (TX). In practice, 8 receivers (RX) can be connected for close range use. 3 Interface Diagram 4 Connection steps 1,Install the antenna and adjust the angle, placed in a reasonable position Please install the included antenna to the transmitter (TX) and receiver (RX) respectively and tighten them, and adjust the angle of the antenna to be parallel or 90° upward, avoiding touching or facing the ground. The equipment should be placed at a suitable location more than 30cm above the ground, and the transmitter and the receiver should be avoided as much as possible between the cover or too much metal shielding objects. 5 2,Power supply Please power the transmitter (TX) and receiver (RX) separately. It is recommended to use the original standard charger, if you use a charger or other power supply device, please make sure that the actual working current of the charger and the power supply cable can not be less than 2A. 3, TX HDMI to host Use a standard HDMI cable ≤ 10m to connect the source to the INPUT connector of the transmitter (TX). 6 4, RX connection to the display Connect the display to the HDMI OUTPUT connector of the receiver (RX) using a standard HDMI cable of ≤10m. Use a standard VGA cable ≤ 10m to connect the display to the VGA OUTPUT connector of the receiver (RX), the maximum resolution of the VGA connector supports 1080P (if required). 5, TX HDMI OUTPUT connection for display (if required) Use a standard HDMI cable ≤ 10m to connect the display to the OUTPUT connector of the transmitter (TX). 7 6,IR connection (if required) A, Use IR transmitter cable (2 sections) to connect to the IR port of HDMI transmitter, and close to the receiver of the signal source remote control. B, Use IR receiver cable (3 sections) to connect to the IR port of HDMI receiver to use the signal source remote control. 7，Audio connection (if required) This feature is optional. The transmitter side uses a 3.5mm audio cable to connect the transmitter R/L IN port to the source audio output port. The R/L OUT port on the receiver side is connected to an audio device such as a loudspeaker Note: Transmitter (TX) must be connected to HDMI signal source, without connecting HDMI signal only connect 3.5 audio input does not work. 8 8，reset to adjust the resolution (if necessary) When accessing the screen is not clear or no signal can be short press the receiver (RX) reset button for about 2 seconds, you can cycle switch 2-3 kinds of resolution, switch to the best resolution, this setting power down to save. Or modify the output resolution of the signal host to achieve the best display. 9 9，network transmission (if necessary) If you need to use a network cable to transmit, it is recommended to use CAT5e/CAT6 or above network cable to connect, the longest distance is 150 meters. When wired connection, if the number of transmitter or receiver (RX) in the same network is more than 1 respectively, please modify the IP of the device, the IP of each device can not be the same, and at the same time, please don't have the same network segment with other network devices, you can modify the network segment. Note: When using a wired connection with one transmitter (TX) and multiple receivers (RX), manually change the IP address of each receiver (RX) without overlapping. Default IP address: TCP/IP IPV4 TX:192.168.1.166/RX:192.168.1.167 How to use RJ45 1、TX and RX pairing; 2、Set the WIFI channel to avoid interference of multiple devices transmitting signals in the same frequency band; 3、For network cable transmission, connect more receivers (RX) to solve the problem of wireless signal can not penetrate; 4, set the transmitter HDMI OUT LOOP resolution; 5, equipment software upgrade. 10 Pairing and Resetting The device is paired by default when it is shipped from the factory, if you need to add a new receiver and restore the factory settings, please follow the instructions below. 1, Pairing A, The device should be connected to the signal source and the screen by the above connection method. B, Use a network cable to connect the transmitter (TX) and receiver (RX), wait about 30 seconds, both ends of the LINK light blinking indicates successful pairing, successful pairing can be unplugged from the network cable to automatically switch to wireless transmission, about 30 seconds to switch successfully. C, if you need to use one transmitter with multiple receivers, follow the above method to pair all receivers with the transmitter respectively. 2, Reset If you need to change the pairing method or abnormal working status, you can restore the factory settings: press and hold the reset button of the transmitter and receiver for about 10 seconds and release it, the LINK goes out to indicate that the factory settings have been successfully restored, and you can set it up again according to your needs.
