Description
Introduction
A standalone TopKAT system can control up to eight electronic hoses or two mechanical
hoses. A master/satellite option allows multiple units to be linked together, with one acting as
the master controlling unit. If you have the master/satellite option, you can control the
following:
• Up to eight electronic hoses and seven satellite readers
• Up to 16 mechanical hoses (two hoses per TopKAT)
• One 9820 or 9800 single or twin electronic hose and up to 14 mechanical hoses (two hoses
per TopKAT).
A standalone or master/satellite with a mechanical Pump Control Unit (PCU) option can
control up to eight mechanical hoses (four hoses per PCU and up to two pedestal or wall-
mounted PCUs).
The TopKAT is equipped with a data key receptacle. Visual prompting messages that are
displayed on the Liquid Crystal Display (LCD) guide the user through the steps required to
activate the pump/dispenser. The display is backlit so that it can be read at night. A 16-position
membrane keypad is provided on the face of the unit to enter data such as Personal
Identification Number (PIN), odometer reading, pump selection, and so on. The unit may also
be equipped with an optional report printer.
The front bezel and rear of the cabinet are hinged doors secured with locks to prohibit
unauthorized access. The front bezel allows access to the optional report printer and paper.
The one-piece hood can be removed for total accessibility during installation and servicing.
When installing the system, ensure that you provide adequate clearance to allow easy access to
both front and rear doors for servicing.
Communication Ports
The TopKAT system contains three asynchronous ports. Typically, Port 1 is used for
communications to a 9800, ASTRA, or Mechanical PCU via RS-485 lines. Ports 2 and 3 can
be set for either RS-232 or RS-422 communications to a data terminal or computer. Refer to
the port wiring diagrams in
for your specific type
of installation. Communication is through direct wire, or by dial-up phone lines using an
optional built-in modem.
If the TopKAT system is equipped with the master/satellite option, the master is the only unit
that will need to have a data communication link. This will collect all transactions and
maintain the complete data base for the entire site. Refer to
“RS-485 - Master/Satellite Option”
on
for more communication requirements.
If the TopKAT is equipped with the wireless option, refer to

and MDE-4520 Enhanced Communications Installation Manual.
