Card Systems

"A" System When you are using an "A" system card that does not use card number and the
supervisor option is required, the field you are using for lockout is also used to
identify the supervisor card. Ranges for this type of card have the digits 30-79 at
the end of the field. These ranges are preceded by 9’s to the length of the field
(for example, the range for a supervisor card if the field is five digits is 99930 to
99979). When the supervisor card is used, data may be entered through the
keypad into any ID field other than the one used for lockout.
Tank Monitor
Description The Tank Monitor option enables the system operator to communicate with a
Veeder-Root TLS tank monitoring system using the Series 1000 as an interface.
Once the communications link is established, commands issued from the Series
1000 data terminal are passed to the tank monitor and data output from the tank
monitor appears at the Series 1000 data terminal. This interface is completely
transparent except for the ENQ character which terminates the tank monitor
interface. The ENQ character is generated by pressing CTRL E. This option
requires the use of the optional auxiliary communications port PCB.
