Hanover supplies four types of sign controller with different levels of sophistication, interface options and feature sets. These controllers cover the wide range of passenger information system requirements from a basic, single sign system (DRS) to a more complex, multi-sign system with additional options such as audio announcements and WiFi data transfer (EG3) The sign controllers house the destination database of messages that are displayed on the signs. This database is programmed using Hanover’s proprietary, Windows based software (HELEN). As with our LED destination signs, all Hanover’s controllers benefit from complete in-house production, excellent reliability and extended warranty terms. Hanover is also able to develop bespoke software solutions to enable the interface of third party equipment to our sign controllers e.g. connection of an existing ticket machine so that the driver only has to set a route code on a single device.
