Put those serial cables on the EDGE…..
Edgeport from Digi international these units can take up to 16 serial cables and with only one USB cable going to the PC. I have the 4 port model and found it on Ebay for about 60.00. Over the past year I have found this unit to work great. You can have all serial cables communicating at the same time. I have never noticed and troubles or slow downs. This is a great solution for the shack with multi serial cables and not enough ports on the PC. If you need it for portable use such as field day it's great as it gets it's power from the USB port so no external power source is needed.Mike Weir, VE9KK, is a regular contributor to AmateurRadio.com and writes from New Brunswick, Canada.
