DStarChatUSB is a Personal Computer (PC) based software application that works with the low speed data port found on current ICOM D-Star® radios. The theme of the DStarChatUSB application is to provide a very simple over the air chat experience along with taking advantage of the Universal Serial Bus (USB) port found exclusively on current day PC computers. The days of the “COM1” serial port are gone. However, ICOM’s implementation of RS232 on the low speed data port placed a big constraint on pure USB communications. Because of this constraint it is still necessary to convert from USB to RS-232. DStarChatUSB tries to hide this as best as possible by requiring the use of a serial converter that is based on the FTDI chipset. Refer to the hardware section of this document for further details.
The look and feel of DStarChatUSB is one of multi tasking and auto management of USB port resources. A major design concept was to be able to recover from most USB port errors without requiring the user to exit and restart the application. By basing the Input Output (IO) resources around the very common FTDI chipset, DStarChatUSB can auto detect and configure the USB port thus eliminating a major headache and wasted hours of trying to figure out “why this serial converter does not work”. All serial converters are not created equal. The recommended cable that works with DStarChatUSB is the COY880. More details can be found at http://www.wb9coy.com/DStarCables.html.
DStarChatUSB is fully compatible with d*Chat. Both applications can seamlessly talk to each other. DStarChatUSB is not compatible with D-RATS, although it will be possible to view the data stream from D-RATS with DStarChatUSB.
DStarChatUSB was written in C# using Microsoft’s Visual Studio 2010 and .NET. More on this can be found in the installation section.
Finally the legal note. DStarChatUSB is free to all without restriction. Use at your own risk, but have fun doing it. 73’s Gene.
