Instructions for setting up the test environment

1. Connect the two radio modems to the computer using a USB-to-RS232 cable

2. Open two serial port assistants (one for sending and one for receiving).
   The serial port configuration for the radio modem is as follows: Baud rate: 115200

   • Data bits: 8
   • Parity : None
   • Stop bits : 1

3. Turn on the power switch of the radio to enter the startup mode. At this time, connect the radio through a serial port and send a command to enter the boot mode. If the serial port assistant is configured correctly, it will display “into boot”.

4. Turn the configuration switch on the test board to the GND end, and the radio outputs ‘configuration mode’. Use the command to set the transmitting and receiving frequency point, air baud rate, working mode and other parameters.

5. Turn the configuration switch on the test board to the VCC end, and the radio will output “transparent mode”. when sending data to the transmitting radio through the serial port, the serial port assistant connected to the receiving radio will display the same data.

Original texts as following:

For Class B

Note : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

For Class A

Note : This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
