a PIN-pad installed. 
2.  If the pump/dispenser has a PIN pad connected, then it can be 
configured to display a receipt prompt as part of the transaction 
authorisation process. This prompt would be the same as for a 
pump/dispenser with a Receipt Printer connected to the C4000 
(detailed on the previous page). To select this option the third digit of 
the Configuration Code for the C4000 should be set to '4' or '5', 
depending upon whether a standard or Secure PIN pad is installed on 
the pump/dispenser. 
Electrical connection of the Receipt Printer in this mode is covered in the 
Central Controller Service Manual. 
Basic Systems (Comcard Compin & CWIDKey) 
For these systems to operate the 'b' setting digit 3 must be set to two. Refer 
'b' Settings (see page 18). In this mode of operation the 'C4000 Head' 
operates as a totally self-contained system operating independently of the 
central controller. The C4000 'Comms' circuitry, which is usually used for 
communicating with a controller, is now used to run an audit trail and/or 
receipt printer (Refer Printer Set-up (see page 40)). These systems can 
have a maximum of 99 cards/pins/keys. 
Comcard Basic 
The Comcard Basic system uses magstrip cards to initiate a transaction. 
These cards are encoded with an access number and a card number. 
There can be only one access number per pump and the card numbers 
must be in the range of 01 to 99. 
 In older Comcard basic systems, card number 99 was 
reserved for servicing. 
All Comcard Basic systems will have a card reader attached to the front or 
side of the pump/dispenser. 
Usually the card number is printed or embossed on the card. If this is not 
the case the card can be identified in the same manner as the CWIDKey 
identification procedure. 
Compin Basic 
The Compin Basic system simply uses a two digit PIN number to initiate a 
transaction. This operates in the same manner as the Comcard Basic 
system except that digit 4 of the configuration code (refer Setting the 
Configuration Code (see page 16) ) must be set to two (2). Also there is no 
access number required. The PIN number acts as the card number and all 
of the same totals are available. 
CWIDKey Basic 
The CWIDKey Basic system uses a CWID (Compac wireless Identifier) key 
to initiate a transaction. These systems have a CWID aerial placed at the 
nozzle or on the pump/dispenser. 
Where the aerial is placed at the nozzle, the CWID tags must be mounted 
in close proximity to the filling spout. If the aerial is on the dispenser the 
customer must hold the CWID tag close to the reader panel on the 
dispenser. The CWID tags are a small (approx. 32mm x 5mm diameter) 
sealed tag. They do not require batteries. 
The CWIDKey Basic system operates in the same manner as the Comcard 
Basic system except that digit 3 of the configuration code (refer Setting the 
Configuration Code (see page 16) ) must be set to six (6). The CWID tags
