Gasboy Gilbarco Interface Unit - Manual (Page 33)

Gilbarco Interface Unit v2.1 Installation 25
Gasboy CFN Series
Receipt lines wrap
Sometimes the CRIND receipt printer may stick in its normal typeface, which has characters too
wide to allow the Gasboy receipt to print correctly. The Gilbarco interface sends the command to
put the printer in narrow typeface mode at the beginning of each receipt. However, the CRIND
may sometimes cease to respond to this. Remove power from the CRIND briefly.
Pumps work but prices won’t program correctly
Every instance of this problem observed to date has been due to incorrect grade programming, or
incorrect price bar programming, or to the SYS_PAR.BIN on page 9: Miscellany: “Blank pump
display after” parameter being set longer than the time between sales.
Prices will not load while the Site Controller is waiting to blank the display after a sale, as
loading the prices will blank the display. Set the wait to 30 seconds in the parameter.
If you have checked Blank after and that is not the problem, review the materials concerning
grade and price bar programming earlier in this chapter, and if that does not help, call Gasboy
service for assistance.
Some sites with nonstandard arrangements of multiple price levels may require more insight
than we offer here to make the price programming work as desired, within the limits of what is
possible with the equipment.
Interface suddenly begins giving unexpected results
This includes sudden failure to function at all, or other serious misbehavior.
If K5 and K6 are out, replace them and do an interface memory clear by opening DIP switch
bank 2, position 2 and pressing the reset button. Be sure to restore DIP switch bank 2, position 2
to the CLOSED position.
If the interface is entirely dead, check the lamps as in Lamp check, above, under Initial
power-up and checkout.
Messages on wrong CRIND or wrong pump activates
The CRINDs are not responding as the same reader terminal numbers the Site controller thinks
they should be. Messages might change on the wrong CRIND when you raise a pump handle.
Also, the wrong pump activates after a card approval.
Possibly the CRIND two-wire addresses are off by one. Did you take into account the
discrepancy between actual two- wire address and the one reported by the CRIND in its
diagnostic test number 6? As mentioned elsewhere, actual is one address less than the reported
number.
Did you enter the wrong “representative pump” in the reader configuration menu 3?
If the site has two interface boxes, did you work out the starting reader number on the
second box correctly? Power down the lowest-numbered reader on the second interface, and see
if the Site Controller reports that the reader you expected went down.
Single pump won’t come up
If everything else works fine but a single pump will not come up, it is possible the interface
needs a RAM clear.
While you are changing pump addresses, if the interface sees even a single poll response
from the even-numbered two-wire address for a PCU, it will not bring up that PCU unless it is
talking to a pump at the even-numbered address.
Singles are usually set up as an odd two-wire address with no matching even address. This
leaves the interface waiting for a pump it will never see.
