1.2 Product Description
The VST Fuel S-810 Fuel Management System is a self- contained, micro-processor based, control and data
acquisition system designed to authorize, monitor, and record fuel dispensing operations. The VST Fuel
S-810 consists of an Island Mounted Data Entry Terminal (DET) which has the capability of simultaneous
control and monitoring of from one to four dispensers. Access input device options for the VST Fuel S-810
are available for magnetic cards, optical cards, touch buttons, or keys. Models are also available which use
keypad entry only and do not require an input device.
Operating the VST Fuel S-810 is straightforward. The user inserts his input device or “keypad entry only” into the
VST Fuel S-810 and enters the required information on the keypad; usually a PIN number and odometer
reading, etc.. If the input device and the entered information are valid, the VST Fuel S-810 applies power
to the requested pump, allowing the user to dispense fuel. At the completion of fueling, the VST Fuel
S-810 transmits transaction information to its output devices and stores the information in its transaction
memory for later recall. The VST Fuel S-810 will hold up to 1000 transactions in memory for
downloading.
The VST Fuel S-810 Fuel Management System has the capability of operating with a wide range of output devices,
which include printers, modems, personal computers, and other devices which are RS-232 or RS-485
compatible.
The various system operations for control of the VST Fuel S-810 and the generation of reports from the VST Fuel
S-810 are thru priority VST Fuel Management, Inc. software. These commands may be issued locally from
a personal computer or remotely by dial-up communications from a personal computer, , or other serial
communication device. Refer to the Operators Manuals and Reference Manuals for additional information.
