I/O signals

The power input interface is a 2PIN PH2.0mm connector. The module board also provides a 5V power output for fan that it may be required when the module is integrated with wireless modules.

Data UART

The 4K module supports one channel uart data packed with the stream and transmitted via the Ethernet. When 4K encoder works paired with 4K decoder and Ethernet linker (wireless or wire), the data to this uart will be transferred to the remote 4K uart.

Control UART

4PIN PH1.25mm connector, TTL 3.3V. The 4K board system can be set-up via this control uart with AT command.

Audio in and Audio out

3PIN PH1.25mm connector. When 4K encoder board works paired with 4K decoder board and Ethernet linker (wireless or wire), it supports bidirectional voice communication. The analog audio input can be line in or Mic in, the analog audio out is designed to output to earphone or audio amplifier.

Ethernet1 and Ethernet2

Two 4PIN PH1.25mm connector, 100M ethernet port.

When the 4K board is shipped as an independent encoding or decoding board, Ethernet1 and Ethernet2 are internally set to bridge, with the same IP addresses for both network ports. The input or output of video data is through the Ethernet1 interface, and Web UI access is through the Ethernet2 interface; Ethernet1 supports connecting with our bidirectional wireless transmission modules or other third-party bidirectional linkers. Ethernet1 supports UDP TS stream, RTSP stream and UDP TS stream + RTSP stream.

When using the 4K board with our COFDM wireless transmitter modulator module (connected through FPC-Main interface via flat cable), Ethernet1 and Ethernet2 are internally set as two independent network ports, with different IP addresses.For this application, the Ethernet1 interface cannot be used externally because network signals are multiplexed to the FPC-Main interface.The Ethernet2 interface can be used as an access network port for the Web UI, or can connect to the IP camera through the Ethernet2 network port. The IP camera video signal can be transmitted through the COFDM wireless module modulator. The below picture shows 4K module connecting with our COFDM transmitter modulator module.

LEDs and GPIO

There are three signal indicator lights (LED1/LED2/LED3) on the right side of the 4K module board, and the indicator light signals are simultaneously connected to the J6011 connector PINs (4PIN 1.25mm connector). Some customers may need to assemble indicator LEDs on their housing case, then they can use J6011 connector PINs to add indicator LEDs on their housing case.

When the 4K works as an encoding board, the corresponding signals of the indicator lights are as follows:

When the 4K works as a decoding board, the corresponding signals of the indicator lights are as follows:

When using J6011 PIN signal to connect LED indicator lights externally, the “positive pin” of the external LED2 and LED3 indicator lights should be connected to the corresponding J6011 PIN, and the “negative pin” should be connected to any GND on the 4K board; When connecting the external LED1 power indicator light, connect the “positive pin” to the J6011 LED1-PIN and the “negative pin” to any GND on the 4K board.

GPIO signal on J6011 connector: reserved GPIO for using as special customized software.
