Luceat RS 485 Installation Manual

Transmission type: mono-directional (1 fiber) and bi-directional (2 fibers)

Supported transmissions: FULL and HALF Duplex

Transmission speed: 300bit/s to 115200bit/s

Transmission distance on plastic fiber: up to 300m

Line termination: 120ohm selectable via Switch

Electrical connections selectable via Switch:

HALF DUPLEX: Rx+ (A) and Rx- (B)

FULL DUPLEX: Transmitter: Tx+ (Y) and Tx- (Z)

Receiver: Rx+ (A) and Rx- (B)

Connectible electrical units: 32 units

Optical connections: 2xF-SMA

Power supply: 12-24Vdc +-10%

Consumption: 0,5W max

Protection grade: IP20

Weight: 85g

Certification: EMC 2004/108/CE

Temperature: -20° / +70°

Assembling: on DIN guide

- Select via Switch the transmission type (HALF or FULL duplex)

- Perform electrical connections:

- With HALF Duplex: connect only 2 wires to Rx+ e Rx- terminals

- With FULL Duplex: connect to Rx+ and Rx- the wire pair that has to transmit data to the optical door,

whereas the wire pair that will receive data from the optical door, has to be connected to Tx+ and Tx-

- Perform electrical connections with 2 or 4 wires:

- Connect the plastic optical fiber

- Supply power to the device
