• Input Voltage 10-48 VDC (56 VDC max)

• Power Consumption 0.5 W (Typical),

1.3W Max

• Duplex multi-mode ber with ST connectors

• Fiber cable specs needed:

62.5/125 micro-meter, 820 nm wavelength

Power the Converter

• Input Voltage 10-48 VDC (56 VDC max)

• Power Consumption 0.5 W (Typical), 1.3W Max

Multi-drop mode allows one serial device to communicate

with up to 31 others around a ber optic ring. Data will repeat

around the ring until it nally reaches its source. When the

data is received by the originator, timeout circuitry will prevent

it from being re-transmitted.
