The displays are connected to the Dupline® bus via the display interface module SBP2DI48524. The displays
operate with RS485 Modbus RTU protocol and shows available spaces using bright green arrows or/and
bright white digits. The displays are programmable from the SBP2WEB24 configuration tool and can be
programmed to show ‘running or steady arrows’ pointing ‘up, ‘down’, ‘left’ or ‘right’. The text display has
the option to show a user-defined text of maximum 9 digits for either a ‘occupied’ or ‘vacant’ situation. In
situations where low ambient temperatures are present (lower than -20 degree Celsius), we recommend
using the version where the heat element is built in. This heat element will have a working display down to
-40 degree Celsius.
The number of displays in an installation is free, until of course, the numbers of addresses in the
SBP2WEB24 are used.
Carpark Display Interface Module
Dupline® to Modbus RTU converter
SBP2DI48524
The carpark interface module is used to connect the Carpark displays directly to the Dupline® bus. Each
module has a unique SIN number and must be programmed by the SBP2WEB24 configuration tool. Each
display must have its own interface module and can be mounted up to 300 m from the display because of
the RS485 connection.
System Structure
At first sight, you may presume that it is a complex task to design a Dupline® parking guidance system for a
parking facility with hundreds or thousands of parking spaces. But when you understand the basic structure
of the system, you will realise that it is simply composed of a number of identically structured system lanes
linked together to create a big system. This chapter begins with a definition of the structure of the basic
system lane. Then we describe how the lanes can be linked together to create the overall system, including
a network for central parking facilities monitoring software.
