Is there a way to make a USB-cable instead? (And to have some chartplotting program recognize this)? What you need is called a serial to USB adapter or converter. You can find them at places like CompUSA, Fryes, Circuit City, Best Buy, Staples, etc. The ones made by Belkin seem to be widely acceptable, I have never found a serial input (including a number of GPS NMEA inputs) that would not work with the one I have. It is a short (10" or so) cable with a USB plug on one end and a small housing with a DB9P connector (looks just like your missing serial port socket) on the other. The Belkin I have (model F5U109) also has three LEDs (RX, TX, LINK) to indicate status of the serial connection and traffic flow. If you are into shopping around for one, try eBay. There are hundreds of them for sale there every day. A search for "serial usb" will turn up a bunch. Jack -- Jack Erbes in Ellsworth, Maine, USA - jackerbes at adelphia dot net (also receiving email at jacker at midmaine.com) For a simple GPS to laptop, any of the run of the mill converters mentioned should work. However, for bi-directional use with a lot of data, only a few more costly units seem to work consistently. I have found this to be the case in programming ham radio and marine radio handhelds such as Vertex/Standard units. My old favorite Belkin failed me there. Raymarine recommends the Sealevel 2105 or 2201 serial port to USB for their RayTech RNS 5.0 software. I don't recall what Furuno or Northstar recommends, but they have similar suggestions. 73 Doug K7ABX |

I am using a USB to serial port adapter. Sometimes it works and sometimes it doesn't. There seems to be no logic as to why CMap sometimes fails to accept the input. The "on" and data lights on the PFranc brand flash but CMap says that there is no connection. I have been using it for 4 years now. I have tested other brands for friends on other laptops and some just do not make a connection. Is it CMap? Any suggestions. Peter Hendra N.Z. yacht Herodotus |
