Ethernet media converter
for industrial use
General
For the extreme demanding use in industrial environments MICROSENS has
developed special media converter.
The converter has included several features such as Link Through, ALM, potential
free alarm contacts, connector for redundant power supply, cross over switch,
solid metal chassis and an extended temperature range.
The industrial product range includes beside the Ethernet (10Base-FL/10Base-T)
and Fast Ethernet (100Base-FX/100Base-TX) converter of this data sheet also
media converter for serial interfaces (RS-232, RS-422, RS-485).

Connections
The connection of the media converter to a hub /switch can be done with a
standard 1:1 patch cable. Because the pinout of the RJ-45 port can be crossed it
is also possible to use a 1:1 patch cable to connect end devices.
Autonegotiation (only for Fast Ethernet version)
This protocol is used during the connection establishment to recognise the
transmission mode (half or full duplex). This ensures that always the maximum
transmission speed is reached. Because the autonegotiation protocol is not
defined for the fiber side, the converter has a helpful manual configuration
feature.
To support the configuration MICROSENS offers this protocol and allows the
configuration of the full duplex mode (DIP switch FD: on). Now the converter is
getting active during the connection establishment and reacts on the
autonegotiation protocol of the connected device.
If this feature is deactivated (FD=OFF) the converter has no effect on the
configuration of the connection. In this case the transmission mode is half duplex
and is interpreted by the connected devices, if autonegotiation is supported by
these devices.

Link Transparency
At most of the application the connection states of each segment is monitored by
the management of the central switch or hub. Using media converter has the
problem that the connection is divided in two different segments. It can happen
that an interruption in one segment is not noticed in the other segment. To avoid
this problem these media converter have the integrated “Link Through”
functionality which is forwarding the link status from one segment to the other.
To ensure that the network management can read the connection status, the
converter has additional integrated features such as Link Through and Advanced
Link Monitor (ALM). The Link Through forwards the connection status to the
converted segment. Due to this the fiber port is interrupted if the twisted pair
connection fails and vice versa.
Additional to Link Through the loss of the transmitting optic fiber can be
recognized by Advanced Link Monitor (switch ALM FX: on). In case of loss of the
fiber port, the copper and the fiber port is switched off (see Fig. 9). This ensures
that the central network components can determinate this failure exactly.
Media converter with integrated ALM feature can be combined with all central
equipment (e.g. switches, hubs, bridges).
Attention: To ensure the correct setup of the connection, only one side of the
connection should have activated ALM.

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.

Mounting
The converter has a very solid metal chassis prepared for the mounting on 35
mm hat rails. The mounting is done on 35 mm hat rails according DIN EN 50
022. The fixation of the MICROSENS switch on the rail is done with a locking pin
that can be opened from the bottom side. Multiple devices can be lined up on the
rail.
