LD-63B Manchester coded And other bi-phase encoded protocols … Designed for Manchester and other biphase encoded protocols, for example, Modbus+ … Galvanic isolation … Full termination and failsafe switch selectable … ST-connectors … SC-connectors (820 nm), multimode … Multimode or singlemode cable … Transmission distance up to 25 km (15.53 mi) … AC-/DC-supply … Reliable performance and function … Withstands environments exposed to high levels of interference Field of application 84 Fibre modem The product is designed for Manchester and other bi-phase encoded protocols with data rates exceeding 500 kbit/s. LD-63B is used for multidrop applications. A common example is Modbus+ which has a data rate of 1 Mbit/s. The B-versions feature an RS-422/485 interface and supports data rates up to 4 Mbit/s. Transmission ranges of up to 25 km (15.53 mi) are possible using singlemode cable. As the fibre cable is completely insensitive to external interference, it is ideal for applications in exposed locations and in environments with high levels of interference. The modems are intended for mounting on a 35 mm DIN-rail, where the modem is attached and locked in a single action. www.westermo.com
