Gasboy Gilbarco Interface Unit - Manual (Page 14)

6 Introduction Gilbarco Interface Unit v2.1
Gasboy CFN Series
Blenders and Gascard Network
Do not use blenders, including three-product fixed blenders, with the Gascard network. This
network uses hose number and will not accept hose numbers greater than 4.
Don’t leave GSM powered down
The GSM uses a non-rechargeable battery which will run down if the GSM is left in a power
down state for an extended period. Immediately upon receipt of your GSM, power it up, and
leave it that way.
Broadcast messages
Currently, Reader Terminal broadcast messages are not displayed on the CRINDS.
Grade restrictions with pre-Advantage MPDs
Grade restrictions, used with some club cards, will not work if you have MPDs older than
Advantage MPDs. These will appear to activate under grade restriction, but will return only zero-
quantity transactions.
Six-digit money on some pumps, five-digit on others
All pumps on an interface must be configured for five-digit money and interface SW3-6 must be
OPEN, or else they must all be configured for six-digit money amounts and SW3-6 must be
CLOSED. Failure to activate correctly or to complete with the proper amount will result if the
interface DIP switch does not agree with a pump’s configuration.
