Gasboy Gilbarco Interface Unit - Manual (Page 30)

22 Installation Gilbarco Interface Unit v2.1
Gasboy CFN Series
GSM Lamp check
Power lamp should be on. Status lamp should show either a steady on-off flash, or it should be on
but interrupted at intervals by sequences of three or four flashes.
The GSM should NOT show a status lamp that is:
Steady off
Steady on
On, interrupted at intervals by ten or more flashes
On, interrupted at intervals by a single flash.
If any of these patterns are observed, contact Gilbarco.
Erase interface unit memory
All checks up to this point should have succeeded. If not, go back, find the error conditions, and
correct them now.
The current loop wiring to the pumps and CRINDs should be connected and set to
NORMAL at the distribution box or boxes.
Set interface unit CPU board DIP switch bank 2, position 2 OPEN and press the RESET
button or cycle power off then on again. This will erase memory in the interface unit. Restore
DIP switch bank 2, position 2 to CLOSED and allow the interface to operate for about three
minutes with all pumps and CRINDs connected. It will then determine the arrangement of
devices it is connected to. This information will ordinarily be retained indefinitely.
If it is necessary to re-address any pumps, repeat the erase interface unit memory procedure.
Connect to Site Controller
You are now ready to connect the interface unit to the RS485/422 loop. Insert the modular
connector on cable C04500 into the site RS485/422 PORT jack on the interface unit, then
observe the interface unit lamps. You should see some activity on lamps L3 and L4 within about
thirty seconds.
If neither L3 nor L4 light, there is a Gasboy data loop RS485/422 problem. If L3 flashes but
not L4, the Site Controller is talking on the loop but the interface is not answering. Check
configuration, and re-check other things up to here.
You should now see some messages about pump control units and reader terminals on the
logger. PRINT DIAGNOSTICS should indicate that the expected pump control units are up.
Verify system operation
If you have a Check Point or a Profit Point on the system, lift each pump handle in turn, and
verify the offhook indication. Use the START key to activate each pump after you have verified
switch detect for each hose on a pump.
Verify that each CRIND is up according to the diagnostics, and then verify that each CRIND
keypad responds as appropriate.
A CRIND that has powered up successfully should say PLEASE PAY INSIDE on the
CRIND display. When the interface successfully polls the CRIND, this message changes to
<PLEASE PAY INSIDE> including the brackets. If the CRIND goes for fifteen seconds without
communicating with the interface, the brackets disappear.
With all CRINDS programmed correctly and DES working key loaded, you should be able
to swipe a card that requires DES encryption. The CRIND should say, “Enter your PIN” or
something similar. If instead it goes back to its initial message, for example “Press payment key”
or if it says “DES not ready”, the GSM is not connected correctly or the working key is not
loaded.
