Gilbarco dispenser interface converter (RS-485/RS-232 to Gilbarco current loop and backwards) is intended for communication with Gilbarco dispensers through interfaces:
- RS-232,
- RS-485 (half-duplex),
- RS-485 (full-duplex),
- RS-485 (half-duplex with control over RTS) (used for PTS controller over fuel dispensers and ATG systems for petrol stations)
Gilbarco dispenser interface converter allows connection of up to 6 Gilbarco fuel dispensers.
