1. Enter configuration mode

Pertama, refer to the VCAN1915 operation manual to learn how to configure the radio and the functions of various commands. The radio can enter diagnosis through the data port, using HyperTerminal or SSCOM3.2 serial port software. Set the serial port baud rate to the current radio interface rate, seperti 115200, memasuki +++ to enter, and NO CARRIER OK is displayed at the same time to indicate that you have entered, and then enter the following commands (each command is followed by a carriage return):

1. TDMA mode

Untuk rincian, refer to the TDMA instructions in the VCAN1915 operation manual. If you need to change, add the following command. OK means correct, dan [MEMASUKI] berarti pengangkutan kembali. Taking one-to-three as an example, the slave address code is 2, 3, 4:

Main station:

ATS251=1—————————————-Set timeout configuration
ATT0=2————————————————–Edit slave station List, starting with station 2
ATT1=3d

2. 900M frequency limit

After entering the configuration mode, you need to enter the following command to set the frequency band limit:

PADA&H0

Radio Telemetry Data Link Parameter modification instruction 5

Memasuki 1 dan tekan Enter

Radio Telemetry Data Link Parameter modification instruction 6

Memasuki 902.400 dan tekan Enter, then enter 907.500 dan tekan Enter, and press ESC twice to exit.

SaveAT&W

The above is that under the condition of 340K air rate, you can limit the frequency from 902.400 untuk 907.500. You can also choose to limit the frequency from 922.800 untuk 927.600. A channel of 400K is required. At least 51 saluran dari 902.400 untuk 927.600 diperlukan. If the air rate is 230K or below, Only one channel of 280K is needed, which can limit the frequency from 902.400 untuk 913.500, or the frequency from 916.700 untuk 927.600. If you need to cancel the restriction, memasuki 000.000 at the beginning and end.
