K3 USB option
Locked

Is it necessary to have the USB option to install firmware updates or is it simply a faster method that I can add on later? What other capabilities does it add?

Hi Jim.
The USB option is a converter that allows you to use an USB port in your computer to communicate with the serial port in the K3. Mainly used if your computer does not have a serial port, or if you need to add another one. You can also install firmware updates via an ordinary serial port. 73 de Kare SM5GRD

The KUSB is a USB to Serial Adapter that connects the K3 to your personal
computer, and should be used if your personal computer has no RS-232 serial ports but has USB (Universal Serial Bus) ports. The KUSB is not something built into the K3, it is an external cable with a USB-to-Serial conversion function in a microcontroller built into the cable. There is a picture of it in the K3 Utility Help. You can install the K3 Utility before your K3 arrives. Under K3 Utility Help, select "Getting started" and "cable requirements". If your PC has an RS-232 serial port, then the KUSB is not necessary. Instead you'll need a straight-through 9-pin RS-232 cable. Firmware updates require that the PC be able to communicate with the K3, either with a 9-pin RS-232 cable attached to your PC's RS-232 serial port, or if your computer has no RS-232 port but has USB ports, you'll need a USB to Serial Adapter like the KUSB for firmware updates (and any other computer rig control you may desire). The KUSB has the right "gender" of connectors (nuts instead of jack screws) so that it will attach correctly to the back of the K3. If you choose another USB to Serial Adapter and it has jack screw connectors, you should also acquire a 9-pin male-to-female "straight thru" RS-232 cable that has screw connectors on each end.

The USB option is simply a USB to RS232 (serial port) converter. You don't need it if your computer has an RS232 serial port. If your computer has USB ports but no serial port, then a USB to serial port converter is needed. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks for the information. I guess I need to reread a good share of the
information, I'm getting old. There is just sooo much (including trying to keep up with the reflector which I don't think is even possible). I have read all the information available except not having finished the actual K3 Manuals itself. Anxiously awaiting my Katiegram, early August? Katie, you listening?

You missed a condition, namely that it is not possible to add a PCI or ISA serial card. For electronic hobbies, there are advantages in having a more directly connected serial card, e.g. - you will need it for accurate time synchronisation to a hardware clock; - you will need it for certain sorts of, timing critical, simple hardware interfaces, such as PIC programmers. -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
