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
2) Decimal value
send(int decimalCode, int bitLength)
3) Tri-state string
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

1. Specification of the communication protocol between computer and the transmitter.
2. Develop a driver (.NET assembly, C# language) that implements that communication protocol.May 10, 2021 at 1:36 pm #8913
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?

Is the transmitter manual available?May 11, 2021 at 3:03 pm #8936
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?

It’s better if you draw a diagram of the system, and show which communication protocols are used on different architecture levels.May 12, 2021 at 3:10 pm #8940
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:
Decimal: 8571080 (24Bit)
Tri-State: not applicable
PulseLength: 321 microseconds
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?

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?May 14, 2021 at 1:47 am #8950
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 lotMay 14, 2021 at 1:05 pm #8952
For the current moment I don’t understand how Rapid SCADA should behave according your task.May 19, 2021 at 1:57 pm #8969
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.

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