: Systems generally accept 14-gauge stranded or solid data wire . For long runs, shielded, 2-conductor cable (such as #22 AWG Belden 88761) is often required to meet safety and performance standards. Protocol Features & Functions
In the modern retail fuel environment, the forecourt is no longer just a place to dispense gasoline; it is a data-rich hub for payment processing, loyalty programs, and inventory management.
