There are a few things you need to be sure of before this will work. - Make sure your RS232 cable has a direct configuration. Pin 2 to pin 2, pin 3 to pin3, and pin 5 to pin 5, end to end.
- Make sure you're using the correct serial port identifier. Usually, native ports have low numbers like COM1 to COM4. As you add ports via the USB-Serial cable, they may pop up on higher port numbers. Sometimes the higher port numbers will be unpredictable. - For your USB-Serial COM port, use USBDevView, available at http://www.nirsoft.net/ for download. You should be able to spot whatever USB COM port identifier is used this way. You can also use Device Manager to examine Ports, just to see which identifiers are occupied (works for native or USB ports). - Try using the K3 utility, and take a look at the COM port numbers that are enumerated. The utility will find all of them on the laptop. Chances are good that your cable is OK, but check it first. Then use the K3 utility or device manager to enumerate all the port identifiers. Try different ports until you get the correct one. Make sure your USB-Serial adapter is actually getting a driver loaded. Normally, after you plug it in the o/s will pop up a little flyover in the bottom right of the screen, noting successful driver load for the newly attached device. If you're not seeing this, it's possible the driver isn't loading. Use USBDevView to watch the device come and go, as you plug it in and disconnect it. This program will also show any USB-based COM ports in the Drive Letter column. You can sort your device list by any of the columns, making this easier to figure out. 73, matt W6NIA On Fri, 07 Dec 2012 23:07:34 -0600, you wrote: >I have been unable to connect to my K3 through the serial port using either >1) 9 pin RS-232 cable direct to laptop serial port or 2) USB to serial port >(FTDI) adapter on either the laptop USB port (running XP) or on the new >Windows 7 desktop machine (no serial ports, so only using the USB).
