How do I reverse this so it works as intended?\n\nBackground:\nI had been the traditional HF ham for years. I had a tower with a TH7 and\na Yaesu G-1000-DXA rotator. I then got into working satellites. I\npurchased a used Yaesu G-5400 rotator and controller. For the five years\nsince installing the elevation rotator I have been manually controlling my\nrotators. I relabeled the up and down buttons on the controller and all\nwas good. A few years ago I purchased a new LVB Tracker from AMSAT-NA but\nit sat on the shelf.\n\nI am now automating my rotators. I have the azimuth rotator working fine\nand have connected the LVB Tracker to control the elevation rotator and\ndone the configuration routine. I can control the elevation using the LVB\nbuttons, but must press up for down and down for up.\n\nI looked at the controller schematic and it appears that pins 1, 2, 3 of\nthe rotator cable connector are connected to the potentiometer: pins 1 and\n3 are on either end of the pot windings and pin 2 is the wiper.\n\nI set the antenna to 0 degrees elevation (0 on far left). I tried\nreversing the wires for 1 and 3, 1 and 2, 2 and 3. I don't think any of\nthese will help me here, but am not sure.\n\nAny suggestions on how to reverse the buttons so that up is up and down is\ndown?\n\nThanks\n\nRolf NR0T\nGrid EN34\n", "attachments": [] }
