IN-2014 is the display module for the Bendix CN-2013 VHF COM/NAV, which in turn belongs to the BX2000 Family. This display shows glide slope deviation and other navigational information using a gas discharge display.
It, unfortunately, means it needs high voltages to operate (to be specific, ±115V DC), so I can’t really test it with the equipment I have at hand.
On the internet, there isn’t much information about this display module, so I purchased an installation manual of the CN-2013 system, and the following is some important stuff specifically about that display module. I hope this is helpful for somebody.
