Note: PMP and PTP modes of operation are controlled by options keys. Refer to these
sections of the manual for additional details.
2.2 Ethernet Port
The Ethernet port (female RJ-45 connector) receives DC power and exchanges data
with the local network. The Ethernet port connects to the PoE Adapter using a
weatherproof CAT-5e Ethernet cable. The maximum total length of the Ethernet cable is
100 m (328 ft). For example, 98 m from the RDL-3000 to the PoE and 2 m from the PoE
to the local network equipment.

2.3 Synchronization I/O Port (PPS)
The PPS port (TNC / F) connector. The function of this port is determined by the
software configurable settings. A protective weatherproof plastic cap is installed on this
port for all new units. This port must be weatherproofed when a synchronization cable
and/or BNC Tee connector is installed.
Note: The RDL-3000 synchronization feature must be used to minimize inter-sector RF
interference at any site where two or more base stations are deployed. This feature
synchronizes the transmit and receive cycles of collocated RDL-3000 base stations to
minimize inter-sector interference. Up to four collocated base stations may be controlled
using the synchronization cables. A GPS receiver is required at each site when the site
is part of a network of geographically collocated cells.
2.4 GPS Antenna Port (GPS ANTENNA)
The GPS antenna port (TNC / F) is available only on RDL-3000 units factory-equipped
with GPS hardware. This port receives signals from a GPS antenna. A protective
weatherproof plastic cap is installed on this port for all new units. The GPS antenna port
must be weatherproofed when a GPS antenna cable is installed.
2.5 RF Ports
The two RF ports are female N-type connectors. The ports conduct RF signals between
the RDL-3000 and the antenna system (ordered separately). Short coaxial cable(s) are
provided to connect the transceiver to an external antenna. The RDL-3000 can be
operated using a SISO (single antenna) or MIMO (multiple antenna_ system.
