2. Quick Start

Note: When using this device must be external 50 ohm impedance antenna, at the same time two devices and antennas
must be used more than 6 meters apart, otherwise there is a risk of damage to the device!!!!
You need to prepare E90-DTU(230SL42) radio, antenna, 12V/4A power supply, serial connection cable.
1, first install the antenna to the digital transmission radio, and then install the power supply, only support the pressure
line method, at this time the power light is on, no indication of abnormal light;
2、Use USB to RS-232 or USB to RS-485 to make the computer connected to the digital radio;
3, start the two serial port debugging assistant, select the serial port baud rate of 9600bps, checksum method for 8N1, you
can realize the serial port transmission;
