VCAN1915 Инструкция за промяна на параметъра на радиотелеметричната връзка за данни

1. Enter configuration mode

Първо, 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, като 115200, Въведете +++ да влезе, 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. Other reference content

    1. TDMA mode

За детайли, refer to the TDMA instructions in the VCAN1915 operation manual. If you need to change, add the following command. OK means correct, и [Въведете] означава връщане на каретата. 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:

    AT&H0

Radio Telemetry Data Link Parameter modification instruction 5

    Въведете 1 и натиснете Enter

Radio Telemetry Data Link Parameter modification instruction 6

    Въведете 902.400 и натиснете Enter, then enter 907.500 и натиснете Enter, and press ESC twice to exit.

Radio Telemetry Data Link Parameter modification instruction 7

    SaveAT&W

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

The above operation instruction is suitable for the below two models:
