K800™ FAQ

1. How do I clear the K800 Fuel Site Controller's transaction memory?
From the main menu select E - Transactions, then from the Transaction menu select D - Erase. You are prompted to enter a date in the format of MM, DD, YYYY. All transactions on or before this date will be erased. If you enter * all the transactions will be erased from the main memory. Once they've been erased, they cannot be recovered.

2. Which communication programs can be used to communicate to the K800 Fuel Site Controller?
There are various types of communication software that can communicate to the K800 Fuel Site Controller. Any software that you intend to use must be able to emulate a WYSE 50 or a VT100 terminal set for 7 data bits, even parity, and one stop bit. The baud rate should be set to 9600 for the terminal port and 1200 or 2400 baud for the modem port. The two most common programs are Windows® HyperTerminal and ProComm Plus.

3. Can the transaction memory be increased in the K800 Fuel Site Controller?
No. The transaction memory in the K800 Fuel Site Controller cannot be increased and holds 1800 transactions.

4. How do I put the pumps in manual bypass?
The manual bypass switch is located on the PV247 Fuel Island Terminal board. Open up the door and find Dip Switch Number 1. The first 4 switches, positions 1 through 4, control the relay position. To place a pump in manual bypass mode close the switch that corresponds to the pump number you wish to place in manual bypass mode. When in manual mode, no fuel transactions are recorded by the K800 system.

5. How do I enable the test mode in the K800 Fuel Island Terminal?
The switch to place the Fuel Island Terminal into the test mode is located on the PV247 board. It is Switch Number 2 Position 8. Move the switch to the closed position then turn the power switch in the Fuel Island Terminal off and on. It should now be in test mode. Simply answer Y/N for the test you want to perform.

6. How do I adjust the contrast on the display?
The contrast adjustment potentiometer, R94, is located on the PV247 Fuel Island Terminal board. To adjust the contrast use a small, flathead screwdriver. Turn it clockwise and counter clockwise until you achieve the best readability.

7. What is the missing pulse detector timer?
The missing pulse detector timer is used to monitor the pulses coming from the pump pulser. If the K800 does not see a pulse in a specific amount of time it will terminate the transaction.

8. How do I validate a key?
From the main menu select D - Card/Key/Account Files, from the Card/Key/ Account Files menu select B - Edit User File (s).
Enter the Card/Key Number and it will then ask you if you want to change it, enter a Y. When validation status comes up enter V for valid. You can keep pressing the enter key to pass through the remaining prompts.

9. How do I configure a replacement dial-in modem for the K800?
When replacing the dial-in modem for the K800 you will have to make sure that the modem is Hayes compatible. You can use a communication program such as Windows' HyperTerminal to communicate with the modem. Send the following command strings to the modem: AT&F, ATS0=1, AT&C1 AT&D2, ATE0, ATQ1, AT&W. If the modem uses error correction make sure it is turned off. Different modems use different commands to turn off error correction; see the manufacturer's manual to determine the correct command string to send to the modem.
