2 Hardware Components of the System
2.1 Central Unit PC
The Central Unit PC with its Central Unit Software is at the heart of the GuidePort
system. It serves to configure the entire GuidePort installation with its cells,
transmitters, events and identifiers. Via a network, the Central Unit PC is connected
with all Base Station PCs of the GuidePort installation.
2.2 Base Station PC
The Base Station PC with its Cell Transmitter Loader Software detects the IDs of all
Cell Transmitters connected to it via a USB. The Base Station PC will transmit the
configuration files created by the Central Unit Software to the Cell Transmitters.
2.3 Cell Transmitter
2.3.1 Description
A Cell Transmitter is a digital unit which picks up prepared MTS data and combines
them with installation-specific control tables and the real-time audio information from its
four analog audio inputs. Via an LVDS interface, the entire data stream is sent to an
Active Antenna Unit where FSK modulation and RF conversion take place. The
transmission of the MTS data is done in a cyclic manner. The cable length between the
Cell Transmitter and the Active Antenna Unit may amount to up to 150 m, which
ensures a convenient installation of the local antennas.
