The following parameters are configured after a reset to critical factory settings:

IP Address = 10.0.0.1

IP Mask = 255.0.0.0

IP Gateway = 0.0.0.0

Administration password = password

User password = password
To perform a reset to critical factory settings:
1. Remove power.
2. Remove connections to the ALARMS port.
3. Hold the RMT button on the front panel while applying power.
Continue to hold the RMT button through the entire boot cycle (approximately 1 to 3 minutes,
depending on the firmware version).
The front-panel LEDs toggle during the boot cycle.
4. Release the RMT button when LED behavior stabilizes.
Coaxial Cabling between IDU and ODU
A coaxial cable or set of interconnected cables must be connected between the N-female TO ODU
connector on the IDU to the N-female connector on the ODU. This cable carries the DC power IF
signals in both directions and the inter-system communications. The cable requirements are:

Maximum RF loss at 350MHz of 16dB

Maximum resistance of center conductor or shield of 1.5Ohm
The maximum resistance specification is typically the defining specification for any selected coaxial
cable. Use the following cable guidelines:

Andrew LDF2-50 Heliax, 3/8-inch Solid Shield, up to 900 feet (270 meters)

Andrew LDF4-50 Heliax, 1/2-inch Solid shield, up to 3000 feet (900 meters)

Times LMR-400, 3/8-inch Braided Shield, up to 600 feet (180 meters)

Times LMR-600, 1/2-inch Braided Shield, up to 1250 feet (380 meters)
Use Solid Shield cable for locations where there is a high level of RF coupling from other cables in
parallel runs up the tower structure and/or where high-powered VHF/UHF transmitters are located
such as broadcast, paging, and cellular transmitters.
Other than meeting the maximum RF loss requirement, the RF loss of the cable does not factor into
system performance.
Coaxial cables have a maximum bend radius and must be handled carefully that over-bending beyond
specification never occurs. Cables bent more than the stated in the bend radius specification may not
meet their specified performance.
