Question: My elevation rotator (Yaesu G-5400) works fine, but to raise the elevation I have to press the down button and to lower it, I press the Up button. How do I reverse this so it works as intended?
Background: I had been the traditional HF ham for years. I had a tower with a TH7 and a Yaesu G-1000-DXA rotator. I then got into working satellites. I purchased a used Yaesu G-5400 rotator and controller. For the five years since installing the elevation rotator I have been manually controlling my rotators. I relabeled the up and down buttons on the controller and all was good. A few years ago I purchased a new LVB Tracker from AMSAT-NA but it sat on the shelf.
I am now automating my rotators. I have the azimuth rotator working fine and have connected the LVB Tracker to control the elevation rotator and done the configuration routine. I can control the elevation using the LVB buttons, but must press up for down and down for up.
I looked at the controller schematic and it appears that pins 1, 2, 3 of the rotator cable connector are connected to the potentiometer: pins 1 and 3 are on either end of the pot windings and pin 2 is the wiper.
I set the antenna to 0 degrees elevation (0 on far left). I tried reversing the wires for 1 and 3, 1 and 2, 2 and 3. I don't think any of these will help me here, but am not sure.
Any suggestions on how to reverse the buttons so that up is up and down is down?
Thanks

Is the antennas physically moving up when you press the up button? IE when you press a button, is the rotor moving opposite, or is the needle indicating opposite?

The antenna is rotating. I do a visual check and the antenna is horizontal. I have the controller indicating zero, I press the DOWN button and hold it for a bit. When I go out and do a visual check the antenna is now elevated above zero.

either the antenna's are installed opposite (flip them 180, and rotate the elevation rotor 180 degrees from it's current position relative to the azimuth rotor), or swap the motor wires to the elevation rotator.

Problem resolved - without ascending the tower.
I had just purchased the PSTRotator software from Codrut YO3DMU to control the rotators. It interfaces with the DDE interface from SDR-Console.which I am using with my FunCube Dongle Pro Plus using the IdiomPress Yaesu DXA CAT card and my Yaesu G-1000DXA rotator. It also interfaces with LVB Tracker for my G-5400 elevation rotator.
So I asked Codrut and he suggested I try swapping pins 4 and 5. I had tried swapping 1-2. 2-3, 1-3 with no luck. I did that and recalibrated the LVB Tracker and I am now fully in business with automated azimuth and elevation tracking of the satellites.
