I can’t help you with the KAT500-Remote Software because I don’t use it.  If you’re not satisfied with how KAT500-Remote is working for you, then I suggest taking a look at the KAT500 Utility software (v.1.19.18.5).  As I explained, simply log into the ham shack computer with VNC Client, TeamViewer, etc.  to manage the KAT500 utility and you’re good to go.  One advantage of this approach is that you don’t have to install the Elecraft software on every ‘client’ computer to be able to access the KAT500 and you’re not limited to a PC as other devices that can run VPN Client TeamViewer, etc.  (iPhone, iPad, Linux, Windows, Android, Google Chrome, etc.) can access the local computer running KAT500.  It also doesn't require port forwarding configuration to gain access to the shack’s PC.

Another approach with the KAT500 Utility is to use a Lantronix EDS4100 (or similar) Serial-to-Ethernet Device Server which provides a ComPort connection between a device (such as the KAT500) and the PC where you’re located.  Connect the KAT500 RS232 port to an open port on the Device Server, install the Lantronix ComPort software on the PC of interest, configure the EDS Device Server with the RS232 settings needed, and now you can connect directly to the KAT500 using the Elecraft Utility Software from wherever you are.  The Lantronix ComPort software configures the PC to accept an ethernet connection and convert the connection to reflect a ComPort.  Windows Manager sees it as a ComPort, and you specify that ComPort in the KAT500 setup (I used Com9 set to 38400 baud).  You’ll will need to setup port forwarding at the hamshack to gain access to the Lantronix brower-based configuration setup and/or run the Lantroix utility software to manage the Device Server.  You can install the Lantronix ComPort software on multiple PCs and they can all access a given ComPort (one connection at a time) for the KAT500. 

I've used the EDS4100 for a number of years to access my KAT500 remotely using the Elecraft Utility running on Win10 on my MacBook Pro running Parallels to create a Win10 Virtual Machine.  I also installed it on the shack PC.   I also used the EDS4100 (which can support four physical ComPort connections) with my KPA500 before I switched to the Remote Rig RC-1216H.   Again, that change was done so that I  could access the KPA500 with a web browser.

In summary if it turns out that you’re not satisfied with your current approach, I heartily recommend using the KAT500 Utility software to manage the KAT500 as I’ve outlined.  You'll have access to the same front panel controls as you would sitting in front of the Tuner:  Power, Tune, Memorize, Mode (Automatic, Manual, Bypass), Antenna (1-2-3).  You’ll also have   “Other” options (Caps on Ant Side, Bypassed, Attenuator, Amp Key Interrupt) and the software  shows you the "Last Observed” Frequency, VFWD, VRFL, SWR, ByPass SWR, Band, and Tune State. It also displays the capacitance (pF) and Inductance (nH) of the tuned ’solution’.

If the KAT500 is on, the connection to the PC will established (assuming your RS232 cable is connected to a PC).  You can see the results in one of two ways:

>> I use a West Mountain Radio R40051 which is a web-based device that has five power ports (Anderson Power Poles) where one provides power to the K3, a second port provides power to the KAT500, a third port provides power to the Remote Rig, and a fourth port provides power to the Antenna Genius 8x2.  Thus, I can shutdown/recycle these devices remotely. I shutdown the equipment when severe storms are expected, or it appears that there may be a glitch that a reboot might resolve.  Given that I’m currently 1,280 miles from the shack, redundancy in the form of being able to power down/power up equipment is a nice feature.

I use a 3A power supply to power the R4005i (it is always on) and second 30A power supply to power the K3-KAT500-Remote Rig-Antenna Genius.  
>> 
>> The KPA500 is controlled separately through a Remote Rig RC-1216H that provides a web-based screen mimicking the KPA500 front panel where I can power on/off and set standby/operate through the interface as well as see the LED meters,  As I use Remote Rig with the K3, the K3/0-mini activates the K3 when the Mini is powered on.  I also use a second RC-1216H to control my Green Heron rotor controller.
>> 
>> BTW, I did a copy/paste of the Activity Log remotely to provide this information to you  as I use a PC in the shack to control the KAT500 and connect via VNC Client from my MacBook Pro.  I accessed the R4005i directly through a web browser to be able to turn on/off the KAT500 with a MacBook Pro.  Thus, I don’t need a PC at my location to control my station as I can use an iPhone or iPad to do it as well.  The station is in Southeast Georgia and I’m currently in Rosllndale (Boston), MA.
