NMEA mutiplexer
"Vic Fraenckel" wrote in message
... Doug, I just had a look at the ShipModul site and read the info concerning both the VirtualPlex-1 software and the MiniPlex-41USB. Both sounded VERY interesting. Could you tell me if purchasing the MiniPlex-41USB includes the VirtualPlex-1 S/W? Is the S/W usable without the hardware? Lots of people seem to be having trouble simply attaching a GPS receiver to their laptops because they have no serial ports anymore. It seems to me that the VirtualPlex-1 SW solves that problem as well. Any enlightenment will be appreciated. Hello Vic, I am the manufacturer of both poducts. The VirtualPlex-1 software is not included in the purchase of a MiniPlex-41USB. VirtualPlex-1 is usable without the hardware, it can be used with any source of NMEA data. But VirtualPlex-1 does not solve the problem you describe. The MiniPlex-41USB connects four NMEA sources to a computer that lacks a serial port. When you only have to connect a single GPS, it is a bit of overkill since a simple USB-serial converter could be used for this purpose. However, many of these converters do not work very well or create the famous wild-mousepointer problem. This does not occur when you use a MiniPlex-41USB, because the supplied driver blocks any Plug&Play requests coming from Windows. VirtualPlex-1 could be described as the software antipode of a multiplexer. It reads the data from one single serial port, beit a real one or a virtual one, and dispatches it to up to 255 virtual serial ports that are created by VirtualPlex-1. This enables multiple software applications to run at the same time and use the incoming NMEA data. Also, VirtualPlex-1 allows the applications to talk back to the 'real' serial port in order to send out NMEA data. Hope this clarifies things a bit. Meindert www.shipmodul.com |
