The Ticket Reader must be connected to a data transmission
line, so that all the necessary information can be transmitted/
received, in a specific management unit, to which the equip
-
ment will be slaved. In the higher performance systems, all the
devices which control entrance/exit to/from the parking area,
are controlled by a Personal Computer (data controller) by
means of the ParkLite software. The lay-out in the following
figure shows the connection of the various types of equipment
which can be connected to the data transmission line. In addi-
tion to this, a table summarises the characteristics required for
operation of the data communication networks.

Network connection between Concentrator PC and NET PC
• The concentrator PC must share the program’
s (ParkLite) work directory with all the NET
computers for access, reading and writing. • If the system uses NET stations, both the concentrator PC and the NET PC must have a static address assigned to them.. • The fundamental parameters for network connection between PCs. such as: IP
address,
Netmask, Gateway
, etc, must be supplied by the customer
’s network administrator
.
RS 485 Data transmission line
• Use a paired, twisted and screened cable for transmission on data network with RS 485 protocol, type Belden 9841 or CEAM
Y09842 or with identical characteristics.
• All devices must be multidrop-connected as shown in lay-out. . • A
maximum of 31 devices can be connected for every line output from the converter
.
• The total maximum distance of the network must not exceed 1200 mt.. • Insert a 120 Ohm termination resistor (insert by shifting a jumper on the Cobra control unit or on the converter) at the end of the line.. • Star-type connections are not permitted. • Do not make any joints on the data transmission cable.
