relay controlled DB9 switch
« on: 2013-04-21, 17:06:20 »
Is there a relay controlled 2 port DB9 switch which could then be switched through the webswitch?
Just a simple relay switched box without any other circuitry for Ethernet or anything else. This would save modifying a manual switched box by installing relays in it.  Any ideas?

Beck,
you can always make or modify a switchbox yourself with a relay
RXD and TXD for normal simple serialswitch (GND not needed)
RXD,TXD,RTS,CTS and if needed also DTR for a full serial switch

Thanks--- Yes I know I can modify a manual switch but if there was a commercial one available that would be
good.  I need one for switching between an Elecraft KPA500 and KAT500 com port through com 1 of the radio RRC. Has anyone done this and how did it work out?
