Programming

How to re-program both firmware and software, in case upgrade is needed.

Programming

Programming is done via the USB port, by downloading either a software or firmware file.  These files are freely available on the website. You should be reasonably technically competent to do this.

Programming using Windows Utility

This method is the preferred way of programming, but is only available on Windows computers.  You do not need to set up the Baud rate, port number etc.
1] Download the Programmer file SFRProg.zip below.
2] Unzip, and place in a uniquely named directory (maybe StaRFIshrail).
3] Using Windows Explorer, check that there are 9 files in the directory.
4] Plug the USB cable between the Windows computer and the hub, and then check that the computer is seeing the hub by looking at "Devices and Printers" pane - there should be an unspecified device named StaRFIshrail.
5] Double click on setup.bat in the StaRFIshrail directory, and a pane should appear This is unfinished - final instructions coming soon.



Devices in Windows

In the Devices and Printers pane in Windows, StaRFIshrail should appear as an Unspecified device.  The drivers should be automatically installed when you plug the hub in on a USB port, as the USB chip used is a standard FTDI USB bridge. The first time you plug in the Hub you should make sure you are on line, as Windows can then search for the installation files if they are not already on your computer.

Programming Method using Terminal window

Connect the USB cable between your computer and the USB port on the Hub.  If this is the first time you are doing this, then makes sure your computer is on-line.  The computer should automatically find the driver for the USB FT234X chip.  You need to have a terminal program installed - Tera Term is the recommended program, which is available as a free download, but you can use which ever terminal program you wish.
The USB serial port should be configured as 115,200 baud, 8 bit, no parity, 1 stop bit.
