Alarm relay contacts
The converter has potential free relay contacts for the connection of external
alarm systems. The connection is done by a 3 pin screw connector at the bottom
of the device. At this connector the pinout, opened or closed (NO/NC), can be
selected. This contact is switched in case of loosing a connection (twisted pair
and fiber) or a general failure of the device.
Length reduction (only for Fast Ethernet version)
Half duplex transmission
The converter has a signal delay of max. 25 bit times. Through this, the
maximum segment length of 412 m is reduced about 25 m for fiber and about 30
m for twisted pair cable. This reduction has also to be considered at single mode
fiber.
Full duplex transmission
In full duplex segments the signal delay has no influence on the maximum
segment length.
Power supply
The power is supplied is done by an external power supply unit, which is not
included at delivery. The connection is done by plug gable screw terminals at the
top of the device. The connection of a redundant power supply is possible with
the second terminal.
