Remote AC power switch?

For those of you implementing remote operation: what are you using for an
IP accessed power switch? I need one port to control station A/C power and
another to toggle the K3s power control line on the ACC connector.

Since I plan on using Teamviewer to control this I could also use a USB
controlled switch instead.

Suggestions welcome.

Thanks

Re: Remote AC power switch?

Jim:

The problem with Teamviewer is that if the PC at the ham station hangs up, you’ve lost control.

I suggest taking a look at using the West Mountain Radio R4005i which provides five ports for powering equipment (each with its own ’soft fuse’) and is TCP/IP accessible through a web browser. I use three of these at my ham location in Georgia to control various devices, including powering on/off Flex Radios. My K3 is controlled through Remote Rig and a K3/0-Mini.

See: http://www.westmountainradio.com/product_info.php?products_id=rr_4005i

West Mountain Radio also offers a ‘PWR AC Controller’ that can power 120VAC devices (up to 15A) using the 12 VDC from the 4005i to turn on/off power to the AC device.

See: http://www.westmountainradio.com/product_info.php?products_id=pwr_ac

Thus, I can control both DC and AC devices without issues. The web interface can be remotely accessed (through port forwarding); one can define the HTTP port as well as the TCP/IP local address, as well as define a login name and password for each R4005i. Since the 4005i is web-accessible, I can access each 4005i independently via web browser on a PC/Mac, tablet, or smart phone as well as reconfigure the 4005i as necessary.

Hope this helps,

I use an old ("telnet" interface) WTI Network Power Switch that I
rescued from a recycle pile. Digital Loggers Inc make a
good/inexpensive "Web Power Switch".

For powering-on the K3 via ACC pin 8, I use a RS232 port on an onsite
PC, with the same simple circuit used for FSK keying.

Re: Remote AC power switch?

I bought a pile of these at $20 US each.

http://www.digital-loggers.com/iot.html

I drive them with PI's or just about anything. It takes any logic from +3V
to 120Vac to control them.

I found that all the other options are great, but very very expensive for
what they are.

The problem with the remote PC hanging up can be handled by removing the
PC power with a remote AC switch and then turning it back on.
Set up the PC to automatically log on and launch the remote control
application at startup. If you do not know how to set that up for your
OS, google will give you some pointers. I know you can do that with
Windows 7 and Windows 10 - don't know about Mac.

Don, also true with Mac OS X and is how I have mine set up for remote operation.

Many of the IP remote power switches (I use DLI) also have a backup control available via a POTS telephone hardline, plus a ping function to do a reset.
