Hi everyone.
I am pleased to announce that the ATAUTO s/w (available from
N3ZH_Software yahoo group) now supports the CK1610 RS232 relay box.
The CK1610 is available here:
http://www.electronickits.com/kit/complete/elec/ck1610.htm
It is the only low cost relay box I can find that works from a DB9 COM
port.
It has 8 relays and 4 isolated inputs.
This relay box is available as a kit or fully assembled.
I purchased mine fully assembled and tested for about $130 including
shipping.
I did not buy the recommended 12 volt power supply because I already
owned a PS that will work.
This box needs 12 volts - not 13.8 volts - not 9 volts - it needs 12
volts - 12 volts.
My laptop has no parallel port - (my wife's desktop computer also has no
parallel port).
Parallel ports seem to be dead - many new motherboards don't have a
parallel port, and laptops have long abandoned providing parallel
ports. The USB/Parallel port adapters are only for printing and do not
show up as a real Parallel port.
The solution?
This CK1610 relay box!
It is now auto-band switching my SGC-500 amplifier.
