    Dear Mr.Mikhail,
    I am now testing to send code of RF transmitter 315MHz to RF receiver on my project using Rapid Scada. I known by Internet that the RF transmitter 315MHz has three methods to send raw codes:
    1) Binary string
    send(string binaryCode)
    2) Decimal value
    send(int decimalCode, int bitLength)
    3) Tri-state string
    sendTriState(string triStateCode)
    So Pls let me know:
    – Can the rapid scada send these codes?
    – Which method?
    – How to configure if the Rapid Scada can send them?
    Thanks and best regards
    From Han Hoang

    Hello,

    You need:
    1. Specification of the communication protocol between computer and the transmitter.
    2. Develop a driver (.NET assembly, C# language) that implements that communication protocol.

    Dear Mr.Mikhail,
    Thank you for your reply.
    I am not IT developer, so i can not create a driver but i have had a another solution. Are you going to develop it?
    Thanks

    Hello,

    Is the transmitter manual available?

    Dear Mr.Mikhail,
    Yes, the transmitter can be manual available. I am using an Arduino as intermediate driver, so i can control a transmitter via Button on Rapid scada Web to send codes.
    But the better is having a driver, ins’t it?
    Thanks

    Hello,

    It’s better if you draw a diagram of the system, and show which communication protocols are used on different architecture levels.

    Dear Mr.Mikhail,
    The diagram of the system is sample: replacing a Buttons on RF(or IR) remote controller (garage door, lights, fan,…) by Buttons on Web rapid scada .
    For example: The EV1527 chipset in garage door remote uses a 24-bit codeword comprising 20 address bits followed by 4 data bits. The codes have been got from garage door remote are:
    Button 1:
    Decimal: 8571080 (24Bit)
    Binary: 100000101100100011001000
    Tri-State: not applicable
    PulseLength: 321 microseconds
    Protocol: 1
    Raw data: 9964,956,332,312,976,312,976,308,980,304,980,308,980,952,340,304,980,956,336,188,908,276,728,264,124,168,308,60,24,60,236,88,88,204,88,76,80,56,1020,284,440,56,24,40,100,84,12,36,56,

    Button Address Data
    Button 1: 10000010110010001100 1000
    Button 2: 10000010110010001100 0100
    Button 3: 10000010110010001100 0010
    Button 4: 10000010110010001100 0001
    So can create a driver that sends commands with above data from Rapid Scada directly to RF (or IR) Transmitter part?
    Thanks

    Hello,

    An I understand you correct:
    When a button in Rapid SCADA is clicked, you need to send a static predefined sequence of bytes? And no response from device to Rapid SCADA?

    Dear Mr.Mikhail,
    The sending a static predefined sequence of bytes when a button in Rapid SCADA is clicked have been worked, but not response from device. I think there was the problem with PulseLength. Have to create something likes as a driver or formula?
    Thanks a lot

    Hello,

    For the current moment I don’t understand how Rapid SCADA should behave according your task.

    Dear Mr.Mikhail,
    My Rapid Scada project is running well now. It can control my devices via RF transmitter.
    For the current moment I don’t understand how Rapid SCADA should behave according your task.
    It is sample. Rapid scada can control devices via Outs as relay. This relay control the Input of RF transmitter. That’s all. You can see my screenshot. Rapid Scada can control all devices at my home. Rapid Scada is great.

    There is bad that have to use many relays.
    Thank You for your attention.

    Hello,

    The screenshot looks pretty good. Thank you for the appreciation of our work.
    Do you have any questions at the moment?
