: I think you both are onto the explanation. I suspected that something was hijacking the port so I restarted the machine and did not run Capn, but instead tried ON Lite and SeaClear separately. Unfortunately that didn't do the trick as the port still appears to be closed to the other software. What would happen if I used an additional USB-to-serial converter in another USB socket? Maybe I'll try the next time I'm at the yard. The Cap'n driver would load and hijack the port on Windows bootup when the drivers load, not the startup apps. The port is reserved by the driver very early in the process.... Try this non-destructive change. Open Device Manager.... Click the + box next to USB Controllers and look for the driver Cap'n has its name on or some USB-to-Serial driver which may be more generic. I've never hunted this driver down, myself. Open any USB controller driver that looks like The Cap'n and look at the driver's author. There is a selector to DISABLE the driver without uninstalling The Cap'n, which would free up the port so your other software could access the USB data coming in. You can always re-ENABLE it to make it work again for The Cap'n. OK your way out and remember how you got there, then try the new softwares. -- Larry |

You can always re-ENABLE it to make it work again for The Cap'n ... I have 2 identical laptops with Capn and the other software installed on each. As far as is possible these are identical installations (the idea being that a complete back-up computer is simpler than reinstalling, reformatting, etc., in a pinch). I used these computers on a recent cruise to southern New England and they were fine, although at that time I had not started messing with ON Lite or SeaClear. BTW these apps were loaded mostly out of curiosity. I may consider migrating if the support situation with Capn remains at its current low level (and I started using Capn with its DOS version in 1993). On the laptop I'm using right now to type this, there is a complete Capn install with a USB-to-serial dongle. This setup was in use recently and ran well, including the interface with the SR162 AIS receiver. I purchased a "Y" adapter from Milltech that allows me to feed the GPS into the AIS receiver, which then transmits the combined GPS and AIS data at 38,000 BAUD to the laptop via the USB-to-serial adapter. A little bit Rube Goldbergy but it works. Believe me, it was way COOL to get targets and CPA on the screen, especially in a breeze at night off Montauk. But that's another subject. Here's some info on the hardware on this box. The Capn works with the associated USB converter. However I also manage my home alarm system with this box. The panel communicates with the DLS software via a serial port, and in the present case I use the same USB-to-serial converter. And it works just fine. In other words on this computer, I can run Capn and get GPS data in the afternoon, then take the computer home and manage the alarm that night. No port hijacking. Puzzling(?). -- Good luck and good sailing. s/v Kerry Deare of Barnegat http://home.comcast.net/~kerrydeare |

My captain didn't like the USB cord dangling off the chart table, so I wifi'd the whole system using a Webfoot RS232 (close enough) to Ethernet adapter on the serial port of the boat's Noland NMEA multiplexer. Cool. Sounds like you need 2 WebFoot adapters unless you have a multiplexer with ethernet out? Is there a provision for multiple listeners on the same ethernet data stream, using multiple Webfoot adapters? |

Is there a provision for multiple listeners on the same ethernet data stream, using multiple Webfoot adapters? The RS-232C port on the Noland is bidirectional. It takes and sends serial data from the one Webfoot fine. I don't think you can connect more than one Ethernet user to it at a time. It's been on the boat and working so long I've forgotten but it doesn't say that in the pdf on: http://www.i****chdogs.com/DataSheets/WF111803.pdf -- Larry |

On both of the laptops I use for navigation, I was unable to find anything in the USB section of Device Manager that was other than Microsoft-generic. All the usual standard drivers from about 2001 for USB hubs, etc. However under the Ports section in Device Manager I located the virtual serial port whose driver matched the driver I loaded from software supplied by the manufacturer. I disabled this, but was unable to see GPS data or capture the port with either SeaClear or ON Lite. I did not yet take a second USB-serial adapter down to the boat yard and try that angle. -- Good luck and good sailing. s/v Kerry Deare of Barnegat http://home.comcast.net/~kerrydeare |

Let's see if there is data on the port and if we can connect to it. Open HyperTerminal from the Windows Accessories/Communications and setup to read the port the NMEA data USB to Serial adapter is using. If NMEA data is on the port, it will stream across hyperterminal like mad. Turn the virtual serial port back on to create the COM port for Hyperterminal to connect to.....Once you get that running and data streaming, these other programs should see it too, but only one at a time. Only one app can connect to a serial port at a time. -- Larry |
