EldMan is a utility tool for Pacific Track ELD (electronic logging device) hardware products, including the PT30 and PT40. EldMan can be used by ELD solution providers and their customers for several purposes, including for manually updating device firmware and for comparing data capture results of an HOS (hours of service) application and EldMan to verify that the HOS application is functioning properly. Note that EldMan is a utility tool only and is NOT an HOS application and cannot be used as part of a certified ELD solution.
