Distance
The PTP 500 Series Bridge will operate at ranges from 100 m (330 ft) to 200 km (124 miles), within
3 modes: 0-40km (0-25 miles), 0-100km (0-62 miles) and 0-200km (0-124 miles). Operation of the
system will depend on obstacles in the path between the units. Operation at 40 km (25 miles) or
above will require a near line-of-sight path. Operation at 100m (330 ft) could be achieved with one
unit totally obscured from the other unit, but with the penalty of transmitting at higher power
in a non-optimal direction, thereby increasing interference in the band. This subject is covered in
more detail in
“Path Loss Considerations”.
5.8
Networking Information
The PTP 500 Series Bridge operates as a transparent Ethernet bridge. Each unit requires an IP
address. This IP address is for management purposes only and it plays no part in the operation
of the system. IP addresses are assigned during initial configuration as described in
“Installation Procedure”.
5.9
Lightning Protection and regulations
The amount of lightning protection is dependent on regulatory requirements and the end user
requirements. The standard ODU for the PTP 500 Series Bridge is fitted with surge limiting
circuits and other features to minimize the risk of damage due to nearby lightning strikes. These
standard features may require some additional equipment to be configured as part of the system
installation to be fully effective. Motorola recommends the use of screened cable and Lightning
Protection units to protect connected equipment from nearby strikes.
NOTE:
The PTP 500 Series Bridge is not designed to survive direct lightning strikes. For this
reason the unit should not be installed as the highest point in a localized area, unless specific
precautions are taken. See
“Lightning Protection”.

Electrical Requirements
The PTP 500 Series Bridge requires one mains supply outlet at each end of the link to plug in the
PIDU Plus units (
“PIDU Plus – PTP 500 Series Bridge”).
