First of all, you should download CUBLOC STUDIO and install it. Comfile Technology's Download page
For the CUBLOC, you only need an RS-232C cable.
If your PC doesn't have an RS-232C Port, you use a USB-to-RS232C cable.
This example will use the MSB612RA-DC. It is single-body CUBLOC module.
Before we start, just enter this source code into CUBLOC studio.
#include "MSB6XX" Do High 32 Wait 500 Low 32 Wait 500 Loop
Go to “PC interface setup” in the “Setup” menu.
Select a COM port for CUBLOC downloading.
Click the red “RUN” icon.
It is just for tasting. If your MSB relay makes a tic-toc noise, that is success.
