FAST-R4T-120

The FAST-R4T includes an on-board RS485 termination resistor. A resistor typically should be used at the last RS485 device to terminate the transmission line and help ensure reliable data communication.

Two models are available to suit different RS485 terminations.

FAST-R4T-120 (120Ω - Yellow) suits most RS485 card readers including HID and Gallagher.

FAST-R4T-330 (330Ω - Red) suits ICT (Protégé) card readers.
