Acromag’s RS-485 network repeater device allows users to take full advantage of the RS-485 standard’s extended communication distances and multi-dropping capabilities. In addition, these devices offer field selectable End-of-Line Network (EOLN) terminations on both the A and B networks.

Operation is transparent to all devices and no handshaking is required. Up to thirty-two RS-485 devices can be driven. Network repeaters are ready to mount on any base plate. Or, for a harsh environment, it can be installed in a NEMA enclosure of your choice. No enclosure is necessary for use in a laboratory or office. Installation requires mounting, connecting power and cables, and setting the baud rate.

ApprovalsUL/cUL listed: Energy management equipment

Key Features & Benefits■ Designed for use with Johnson Controls

N2 or BACnet bus

■ No handshaking

■ No extra control lines

■ I/O signal isolation

■ Baud rates of 600, 1200, 2400, 4800, 9600,19.2K, 38.4K, and 76.8K are switch selectable

■ Field-selectable end-of-line networkterminations on both A and B sides

■ Electrical transient protection is provided. Thisprotects the host computer from destructivenoise spikes and othertransient signals.

■ Status LED’s indicate transmissiondirection, RS-485 bus fault conditions, andpower applied.

■ 24/115/230V AC power available

■ No separate transformer required with 24V ACunits (4683-TTM-3F)

OperationModel 4683-TTM-xF network repeaters isolate and boost RS-485 signals allowing communication signals to travel another 4000 ft. Each repeater permits the addition of another 32 unit load to a network.

The repeater has two RS-485 “sides” known as the A and B sides. The A side typically connects to the network towards the host and the B side connects to the extended network. Functionally, the A and B sides are equivalent.

Repeaters receive AC power through a 3-screw terminal strip. Transient signal protection is provided on both RS-485 sides.

When both RS-485 lines are idle, each side is in receive mode. When a ‘1’ to ‘0’ transition is detected (signifying a start bit) on either side, the opposite side’s transmitter is enabled. The transmitter stays enabled for one character’s time (based on the baud rate switch setting). The received character is then passed through.

For N2 or BACnet MS/TP bus ◆ Drives up to 32 RS-485 devices ◆ Isolates and boosts signal up to 4000 ft.

■ Communication SpecificationsBaud RatesSwitch settings on unit for 600, 1200, 2400, 4800, 9600, 19.2K, 38.4K, and 76.8K baud rates. Switch must be in the proper baud rate position for proper operation.RS-485 Bus LoadingOne unit load equivalent.RS-485 Bus DriveComplete RS-485 compliance for up to 32 unit loads (31 unit loads if a repeater is used).End-of-Line Termination NetworkThe EOLN termination network is shown on the right and is individually selected on both the A and B sides by a pair of shorting clips. The A-side is controlled by jumper pair J1, J2 and the B-side is controlled by jumper pair J3 and J4.The EOLN termination network is enabled for the A side or B side when the associated pair of jumpers are positioned over pins 1 and 2. Conversely, the EOLN is disabled (out of the circuit) when the pair jumpers are positioned over pins 2 and 3.DuplexHalf duplex only.Data FormatTen bits typical (1 start bit, 8 data bits, and 1 stop bit). Other formats are supported.
