Description Key Features & Benefits Operation ■ Designed for use with Johnson Controls Model 4683-TTM-xF network repeaters Models N2 or BACnet bus isolate and boost RS-485 signals allowing 4683-TTM-1F: 115V AC Power communication signals to travel another 4000 ft. 4683-TTM-2F: 230V AC Power ■ No handshaking Each repeater permits the addition of another 32 4683-TTM-3F: 24V AC Power ■ No extra control lines unit load to a network. Acromag’s RS-485 network repeater device ■ I/O signal isolation The repeater has two RS-485 “sides” known as allows users to take full advantage of the RS-485 the A and B sides. The A side standard’s extended communication distances ■ Baud rates of 600, 1200, 2400, 4800, 9600, typically connects to the network towards the and multi-dropping capabilities. In addition, 19.2K, 38.4K, and 76.8K are switch selectable host and the B side connects to the extended these devices offer field selectable End-of-Line ■ Field-selectable end-of-line network network. Functionally, the A and B sides are Network (EOLN) terminations on both the A and terminations on both A and B sides equivalent. B networks. ■ Electrical transient protection is provided. This Repeaters receive AC power through a 3-screw Operation is transparent to all devices and protects the host computer from destructive terminal strip. Transient signal protection is no handshaking is required. Up to thirty-two noise spikes and other provided on both RS-485 sides. RS-485 devices can be driven.
