3. Other reference content

    1. TDMA mode

For details, refer to the TDMA instructions in the VCAN1915 operation manual. If you need to change, add the following command. OK means correct, 과 [입력하다] means carriage return. Taking one-to-three as an example, the slave address code is 2, 3, 4:

        Main station:

• ATS244=1—————————————-Change to TDMA mode
• 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:

    에&H0

    입력하다 1 and press Enter

    입력하다 902.400 and press Enter, then enter 907.500 and press 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 에게 907.500. You can also choose to limit the frequency from 922.800 에게 927.600. A channel of 400K is required. At least 51 채널 902.400 에게 927.600 are required. If the air rate is 230K or below, Only one channel of 280K is needed, which can limit the frequency from 902.400 에게 913.500, or the frequency from 916.700 에게 927.600. If you need to cancel the restriction, 입력하다 000.000 at the beginning and end.

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