[amsat-bb] Mirage Rotor Interface.

Hi All, I picked up a G5400B rotor control box with a Mirage interface on top of it. It has a model number of MTI. Does anyone have any information on this unit. It has the connector for the 5400 and a db25 serial male. Front has lamp indicators for cw ccw up and down and a switch for auto or manual.

Thanks Joe KI4TZ
