About this Manual
Installation Guide MIL-185C/MIL-195C
Operating Conditions
This manual covers both the MIL-185C and the MIL-195C
media converters.
The terms “converter” or “device” are used throughout
the document to describe either the MIL-185C or the
MIL-195C.
Introduction
The MIL-185C and the MIL-195C are compact, physical
media converters that allow the user to convert signals
between ATM fiber optic cabling in either multi-mode or
single-mode, and UTP cabling. Both converters support
OC-3 (155Mbps) speeds.
Features
• Fiber budget sufficient to drive 2 km for multi-mode
or 15 km for single-mode fiber
• One SC-type single-mode (MIL-195C) or one SC-type
multi-mode (MIL-185C) connector
Table 1: Recommended Operation Conditions
Parameters Minimum Maximum
Operating Temperature +5° C 40° C
Humidity: non-condensing 10% 95%
Signal Output Load 35 ohm 75 ohm
Supply Voltage 4.75 V 5.25 V
Power Supply
External power is required. The device draws 900 mA at
normal operation in room temperature of 25° C.
• Domestic: 110 V AC wall mount power supply.
• International: 220 V AC power supply with IEC
receptacle.

MIL-195C
The MIL-195C converter supports full-duplex ATM
Fiber/UTP links. For fiber budget constraints, the MIL 195C has a launch power of -19 db and a receive
sensitivity of -30 db (using a 1300 nm class 1 laser). In a
full-duplex environment, up to 100m of CAT 5 UTP and
15km single-mode fiber can be used.
Installation Guide MIL-185C/MIL-195C
Installation
To install either converter:
1. Attach the CAT 5 UTP cable from the network to the
RJ-45 port on the device.
Note: Use screened CAT 5 UTP cable for CISPR-22 class B installation.

2. Attach the fiber network cable connectors to the
connectors marked “RX” (Receive) and “TX”
(Transmit).
3. Connect the power receptacle from the wall adapter
to the unit.
4. Verify that the power LED illuminates.
5. Verify that both the UTP and the FIBER active LEDs
also illuminate when all cables are attached.
Important notice: This device is set to half duplex mode at the factory. If you are
experiencing excessive collision errors or CRC errors, then you
must force full duplex mode operation on the connecting
device(s) before you power up the MiLAN device(s).
Diagnostic LEDs
• UTP ACTIVE: Illuminates when the device receives a
valid signal from the device connected to the UTP port
• POWER: This LED illuminates when the device is
powered up
• Minimum: -25° C
• Maximum: 75° C
• FIBER ACTIVE: Illuminates when the device receives a
valid signal from the device connected to the fiber port.

MIL-185C
The MIL-185C converter supports full-duplex ATM
Fiber/UTP links. For network budget constraints, the
MIL-185C has a launch power of -19 db and a receive
sensitivity of -31 db (using a 850 nm class 1 laser). In a
full-duplex environment, up to 100m of CAT 5 UTP and
2km of multi-mode fiber may be used.
