It may take up to several minutes after the CRINDs and the GSM are connected before the
CRINDs are ready to perform DES encryption. Transactions that do not require DES may
proceed during this time.
Test for multiprice incompatibility
You may skip this procedure at your site if:
• all pumps are either Highline or Salesmaker-2, or
• all pumps are Advantage with firmware 70.5 or greater, or
• every pump is one of the preceding types.
If you are changing over from single price or cash/credit pricing to additional prices at
levels 3, 4, or 5, and you have not previously performed this procedure, you should perform it
now.
If your site will operate with only one price level, or with cash and credit pricing and level 0
same as either cash or credit, you may skip this procedure. For this decision, prices at level 6 and
above do not count.
Do not perform this test while the site is open for business.
1. On the interface CPU board note the settings of DIP switch bank 4, positions 1 and
4, then change them to position 1 CLOSED and position 4 OPEN. Press RESET on
the interface unit.
2. For one pump of each multihose or multigrade variety, load price levels 0, 1, and 2
each with different and unique prices.
3. Select a pump under test and press START on the Check Point or Profit Point.
4. Raise the leftmost pump handle. Pump a very small amount of fuel. Lower the han-
dle.
5. Press CASH then START on the Check Point or Profit Point.
6. Raise a different pump handle and pump a small amount of fuel. Note whether the
price shown on the pump is the expected cash price for the fuel pumped. If not, you
may not operate this pump in multiprice mode, except for cash and credit prices.
7. Lower the handle and print a receipt.
8. Determine whether the total amount shown on the receipt agrees with what was
shown on the pump. If not, you may not operate this pump in multiprice mode,
except for cash and credit prices.
9. Restore DIP switch bank 4, positions 1 and 4 to their previous settings and press
RESET on the Current Loop Interface CPU board.
If you find a pump that does not operate correctly in this mode, please determine the pump
model and firmware revision number, and report them to Gasboy Technical Service (by fax, if
possible). We will attempt to maintain a list of models known not to work in this mode, for the
benefit of our customers.
Troubleshooting
This section is a collection of known problems not necessarily discussed elsewhere in this
manual. It pertains more to sites that have started successfully, but either fail to become fully
functional, or develop subsequent problems. This section is not exhaustive, but instead attempts
to mention some of the more common problems reported.
If you find a problem you think should be included, contact your Gasboy sales or service
representative.
