MZC combined with Single Spot Detection
The MZC can easily be combined with the Single Spot Detection System� The data from the two sys-
tems are being sent on the L2 bus in exactly the same way to be read by the master carpark monitors
and shown on the displays�
When programming the master carpark monitors controlling the displays, it is necessary to know the
L2 ID number for each zone in order to include the right zone(s) for each display� This information
is made available in the final MZC report when a project is built (see Design and Installation Guide
for Carpark Zone Counter)� Here it is also possible to define the L2 ID for the first zone, and then the
remaining zones will follow in consecutive order�
It is also easy to include the values from the MZC in the optional Carpark Software, because the
MZC is able to emulate up to 32 standard GP34960005 Carpark Master Modules on the two RS485
ports (ID 1-16 on port COM1, ID 17-32 on port COM2)� The standard Carpark Master Module has 6
DIP-switches to select a device address between 0-63� In the MZC these device addresses for the
emulated Carpark Master Modules are for simplicity reasons identical to the above mentioned L2 IDs�
These IDs are needed when configuring the Carpark Software�
As shown on the diagram next page, the Carpark master module G349600005700 on the L2 bus is
not needed in this case, because the L2 Carpark Master Channel Generator is driving the L2 bus�
