Please note: This is a Sole Source Notification. Specifications include, but are not limited to: Syntech Systems, Inc. (STS) is the sole source for all FuelMaster Software and Hardware. Syntech Systems, Inc. designed and developed the software to work with its accompanying hardware – FuelMaster model series 2000, 3000, 4000, 5000 and AIM product line. Additionally, STS holds the copyrights to the FuelMaster source code and patents on the accompanying hardware. All software and hardware are developed and maintained by Syntech Systems, Inc. Fuel Management Systems (FMS) are proprietary and cannot be interchangeable. A fuel management system has three major components: the island controller, the access device that activates dispensers through the island controller, and the system software that provides reports and data. All three components must be from the same manufacturer for the system to operate. The access device (in this case the Prokee read/write key) must be able to fit into a receptacle designed to be received by the island controller and match the information within the correctly designated fields. Or, if using AIM equipment, the island controller must communicate by radio frequency to the vehicle AIM device and vice versa. If the system’s hardware and software are Incompatible, the fuel dispensers cannot be activated, or access the transaction data captured by the island controller.
