A Linux based remote control system

We are extending LANs out to transmitter sites for many reasons; backup audio, control and monitoring, security systems, VOIP phones, etc.

I am casually (very casually) toying around with creating my own Linux based remote control system.  The ongoing Windows 10 upgrade debacle continues to not end, I can’t help but think that there are many potential clients who could use a reliable transmitter/studio remote control and monitoring system based on a stable operating system.  Hmm, sounds like a sales pitch 😉

Anyway, I have run across several Ethernet board manufactures that offer a variety of boards with 8-12 contact closures and a variety of analog and digital inputs.  Most new transmitters have some sort of web GUI which are great for transmitter control and monitoring.  As we all know, there is more than just a transmitter at any given transmitter site.  In addition to the transmitter, I would like to control and monitor things like tower lights, interface and control of coax switches, temperature monitoring, generator status, the old non-web interface backup transmitters, STL signal strength for those old 950 MHz links, etc.

Since Google is my friend (when they are not storing my search data), I came up with this: Internet-ethernet-12-channel-relay-board

That particular PC board is made in Bulgaria, which is home to this: Mount Buzludzha

What I like about these particular boards is the DRM software (DRM has, apparently, many different meanings) which will run on Linux or Windows.  There are also iOS and Andriod applications that can be used as well.  It appears that the GUI can be customized for various uses.   This seems like it is written in Java, so perhaps I could have some Java expert customize it for radio use.  It looks like up to 32 boards can be controlled by a single instance of the DRM software.  Alarm reporting would be via SNMP trap and email.

I don’t know, there is one particular cluster of stations that needs new remote control gear at almost every transmitter site.  Perhaps a little alpha testing is in order?  It could be fun…

Anyway, just a thought…
