4.3 Product indicator meaning

The STS light represents the SNR size of the received signal
STS colour	SNR
Azul	No connection is established
verde	SNR>10dBm
amarillo	6dBm<SNR<10dBm
rojo	SNR<6dBm

Módulo	Modo	PWR led	LAN led	STS led
Maestro	no sincronizado	The green light is steady on	Los datos se están transmitiendo y parpadeando.	The blue light is steady on
Maestro	sincronización	The green light is steady on	Los datos se están transmitiendo y parpadeando.	（green/yellow/red） Proportional to the strength of the received signal
Esclavo	no sincronizado	The green light is steady on	Los datos se están transmitiendo y parpadeando.	Blue light flashing
Esclavo	sincronización	The green light is steady on	Los datos se están transmitiendo y parpadeando.	（green/yellow/red） Proportional to the strength of the received signal

When the primary and secondary devices are not synchronized, the power PWR indicator of the primary and secondary devices is steady on, and the STS blue indicator of the primary device is always on. The blue light from the device’s STS flashes. When the master and slave are synchronized, the master and slave’s STS light becomes a three-color light, and the green light is displayed if the signal quality is good. A yellow light indicates moderate communication quality. A red light indicates poor communication quality. Cuando el puerto de red envía o recibe datos, the LAN indicators of the primary and secondary devices blink.

5.4 Serial Settings

The Vcan2149 device has two serial ports, among which the level of serial ports 1 y 2 is RS232 or TTL level. The level of serial port is determined by the factory hardware, and the customer cannot modify it by himself. When serial port 2 is TTL. Puerto serie 2 can also be used as two SBUS. The SBUS pins at the ground end are input IN, and the SBUS pins at the sky end are output OUT. SBUS also supports 5V output.

The serial port of the Vcan2149 supports the serial-to-network function. TCP and UDP can be used for serial transmission. The default port number of serial port 1 es 3001, and that of serial port 2 es 3004.

5.4.1 Serial-to-Serial

The mapping between the remote serial port and the local serial port is one-to-one. Por defecto, remote serial port 1 corresponds to local serial port 1, and remote serial port 2 corresponds to local serial port 2.

5.4.2. SBUS Configuration

1. Open the sky side and the ground side of the WEB, click the left serial port configuration.
2. Change the serial port 2 mode on both the primary and secondary ends to SBUS mode.
3. Change the SBUS mapping of the sky side to PIN12 input corresponding to PIN12 output, PIN13 input corresponding to PIN13 output. The SBUS mapping configuration on the ground end is invalid.

Primero, you need to configure serial ports 2 of the primary and secondary stations as SBUS. The module supports two SBUS. Además, patas 12 y 13 at the ground end are SBUS inputs. Alfiler 12 and Pin 13 at the sky end are SBUS outputs. los 12 pins at the sky end correspond to the 12 pins at the ground end. los 13 pins at the sky end correspond to the 13 pins at the ground end

5.4.3. Serial port to network port/Network port to serial port

The function of serial switching, or network switching is mainly serial port input, salida del puerto de red o entrada del puerto de red, serial port output, etc.. The serial port on the sky end is configured as TCP or UDP for transmission. The following is an example of a Mission Planner ground station performing TCP/UDP protocol transmission.

Paso 2: MP seleccione el modo UDP, la velocidad en baudios del puerto serie no es necesaria, click the Connect button. Enter Local port: 3001 (puerto serie 1). 3004 (puerto serie 2).

5.5. Pairing Settings

The pairing function can be realized by hardware configuration and software configuration. The ID number can be configured on the primary end to determine whether to use the random ID number or the fixed ID number of the original primary end for automatic pairing. This parameter is invalid for configuring ID mode on the secondary end.

Pairing premise:

The pair device can be paired only when it is a primary device and a secondary device. If both devices are primary devices or secondary devices, the pair cannot be paired.

Hardware pairing conditions:

1. Effective within 60 seconds after starting, invalid after 60 artículos de segunda clase.
2. Invalid in connected (sincronizado) estado.
3. The pairing mode has been entered once after startup, and it is invalid even if

the time is still within 60s.

Hardware pairing Settings:（The Air unit and the ground unit are configured independently）

• Web configuration: Select serial port 1 or serial port 2 or serial port 4 as the

paired serial port.

• After the configuration, short connect the TX and RX of the corresponding serial port for at least 2 artículos de segunda clase. Customers can solder a switch button themselves by long pressing it for more than 2 artículos de segunda clase. TX and RX can also be

looped together.

• If the RSSI indicator blinks and turns off, the device enters the pairing mode.

Wait until the peer device also enters the pairing mode.

Software pairing Settings:

Haga clic en “Start Pairing” button inside the page to start pairing. Después 2 minutos, if

the pairing fails, the device displays the status before the pairing again.

5.6 IP configuration（Network Settings）

1.The default local IP address of the primary node is 192.168.10.250.

2.The default local IP address of the repeater node is 192.168.10.251.

3.The default local IP address of the slave node is 192.168.10.252.

4.The Alternate IP address is 192.192.192.192.(cannot be changed) 

5.7 Wireless Status

Wireless status is mainly to display channel information, such as master and slave nodes, whether to synchronize, working frequency points, distance display and network data volume statistics. It also displays the status of the local device and some information about the remote device. Por ejemplo, MCS (stream mode), transmitir potencia, twochannel received energy, two-channel received signal-to-noise ratio and error packet PER display.

The distance display can only be displayed by the master. The detection of background noise is carried out when the master is powered on. The slave does not detect background noise before synchronization. The slave detects background noise only after synchronization.

The network transmission of the master indicates the amount of data sent by the master to the PC. The network reception of the slave indicates the amount of data received by the slave from the camera.

5.8 Wireless Noise

Background noise detection is mainly used to detect ambient interference of master and slave equipment. The red line represents the bottom noise at the primary end and the blue line represents the bottom noise at the secondary end. And the lower the absolute value, the cleaner the floor noise, eso es, the smaller the interference source. Por ejemplo, -100dBm is better than -90dBm. Floor noise detection can quickly help customers determine whether there is interference in the test environment.

• Floor noise detection in clean environments

• Floor noise detection when there is interference

5.9 Restablecimiento de fábrica

   The default factory Settings of the device are the secondary (aerotransportado) parámetros, and the default network IP address after factory restoration is 192.168.10.250.

5.10 Software Upgrade
