Parking Data Acquisition

SWARCO's DZK UNI is one of the most efficient and accurate parking data acquisition units on the market.

The information about incoming and exiting vehicles is supplied by the parking system, either by potential-free contacts (e.g. barrier systems), inductive loop detectors, or by a serial interface to an existing car park management system. The parking data acquisition unit DZK UNI is installed either in the control room of the car park or, for open parking areas, in an outdoor plastic control cabinet.


The core of the parking data acquisition unit DZK UNI is a multifunctional base module. Together with its controller, the module takes over the parking space occupancy detection, the control of communication to the connected interfaces as well as manual control panel supply.

  • Reading of contacts, or data transfer via serial interface
  • Configuration and correction of parking space selection
  • Communications via higher-level computer (main car park computer)
  • Communications via displays directly connected to the DZK UNI
  • Time base for statistical data
  • Automatic start-up after power failure
  • Storage of occupancy times in case of power failure
  • Designed for installation in multi-storey car parks

The module has the following system properties:


IPC@Chip SC23

Interfaces e.g.:

Serial 1 - RS 232 (RxD, TxD, RTS, CTS), serial 2 - RS 232, RS 485 or TTL,

serial 3 - RS 232, RS 485 or TTL, Ethernet 10/100 MBit, 1x CAN bus (detector connection),

1x USB 1.1, 1x SD card slot (optional)

Power supply:

24 V DC

Voltage output:

Supply of a voltage output of 5 V DC for an external modem


Approx. 100 x 160 x 50 mm


Data acquisition options (DZK UNI / -S / -D / -P):

  • -S: Serial connection to all commercially available parking management systems
  • -D: Data acquisition via inductive loops via built-in IC detectors
  • -P: Data acquisition via the reading in of potential-free (barrier) contacts (16 inputs, 4 outputs which are potential-free in the module)
