The supply voltage range of OUR is 7V~36V, 24V as default.

Uart port

Before shipment, the UART port can be configured as a TTL, RS232, or RS422 UART port based on customer requirements. The TTL/RS232 UART port operates with an 8-bit data format, 1 stop bit, and no parity check.

• Configuration Mode: Fixed baud rate of 9600.

• Data Transparent Mode: Configurable baud rates: 9600, 19200, 38400, 57600, 115200, 230400, 460800, or 921600.

Recommended Baud Rates for Different RF Bandwidths:

• 1MHz RF Bandwidth: 921600 baud

• 500kHz RF Bandwidth: 460800 baud

• 250kHz RF Bandwidth: 230400 baud

• 125kHz RF Bandwidth: 115200 baud

Matching the UART baud rate with the wireless throughput ensures stable data transmission and prevents packet loss. The UART ports are primarily used for radio parameter configuration and data transmission.

 

M1 Dip Switch

The M1 and M0 signals (with M0 located on the J30JZ-9PIN connector) control the operating mode of the radio.

Operating Modes

The radio supports two modes:

1. Data Transparent Transmission Mode

2. Configuration Mode

Users can set the system mode by adjusting the voltage levels of M0 and M1:

• Configuration Mode: Activated when M0 and M1 have different voltage levels.

• Transparent Transmission Mode: Activated when M0 and M1 have the same voltage level.

By default, the M0 and M1 pins are internally pulled up to a high level, placing the system in transparent mode. To switch to configuration mode, suspend M0 and turn the M1 dip switch to the “C” Configuration side. To return to transparent transmission mode, turn the M1 dip switch to the “D” Data side. Mode switching occurs in real time without requiring a system restart.

Configuration Mode

• The radio only responds to configuration commands and does not transmit received serial data to the wireless port.

• Incoming signals from the wireless port are not forwarded to the serial port.

• The UART baud rate is fixed at 9600, with 8 data bits, 1 stop bit, and no parity check bit.

• Only local configuration parameters can be modified.

Transparent Transmission Mode

• If the received serial data is a configuration packet, the radio performs parameter configuration.

• If the received serial data is not a configuration packet, it is transmitted to the wireless port, and incoming signals from the wireless port are forwarded to the serial port.

• Both local and remote parameter configurations are supported.

Indicator LEDs

 

LED	Description
PWR	Power led, Red light on normal powered.
TX	Green, data transmission led, briefly light during power on self-test, light when data is transmitting.
RX	Green, data receiving led, briefly light during power on self-test, light when receiving data.
CA	Blue, interference led, briefly light during power on self-test, light in configuration mode. In transparent transmission mode: When it light on, it means exist interference and the brighter the light, the stronger the interference signal.
FU	Blue, data cache indicator led, briefly light during power on self-test, light when data cache is full.
HFU	Blue, data cache indicator led, briefly light during power on self-test, light when data cache is half full.

To maintain high communication quality, the system includes an internal data buffer with an adjustable size. A larger buffer reduces the risk of data loss but may increase latency. The buffer status can be monitored using the FU and HFU indicator LEDs.

It is generally recommended that when the HFU LED is lit, the host computer should temporarily pause data transmission to prevent the buffer from reaching capacity and causing data loss.
