Open the Command Prompt do all these steps from the same command prompt.
1. Right-click "Command Prompt" in Accessories and choose "Run as Administrator" if using
Vista or Windows 7
2. Enter "set devmgr_show_nonpresent_devices=1" – without the quotes obviously
3. Enter "start devmgmt.msc"
4. In the box that opens, select "Show hidden devices" in the 'view' menu.
Now if you expand the section on COM ports, all the COM ports that have ever been created will be
displayed, the non present ones being in grey. You can uninstall away anything that you don't want
(right click, select uninstall).
USB Port Management:
For USB port management, I would highly recommend USBDeview available for free at
www.nirsoft.net
It tells you more about the current and past USB ports then you'll ever want to
know and provided me with some insight into a problem associated with the ICOM USB Driver
software. Suggestion by Ken Goodwin K5RG
Common Error:
The PW-1 has two 'remote' or CI-V that are internally are wired together. Do NOT wire each of
these to a separate port of the router.
Acom 2000
I have worked with Bill, N3RR getting the K9JM router to work with an Icom radio and the Acom
2000 amplifier. The Acom, when connected to the CI-V bus will act like a controller whose Icom
address is 0xE0, identical to that of all other software programs. This confuses the router, much
like having two Ethernet MAC addresses on the same network. Also, the Acom does not have a
'normal' CI-V interface, and to make electrical connection, much more pull up current to 5 volts is
required. This can be accomplished by reducing the value of a resistor on the K9JM CI-V interface
board. I have a cut of software designed to handle the Acom 2000 and can easily modify the
interface board to operate with the Acom 2000. Contact me for further details.
