RDL-3000
2.2

Ethernet Port

The Ethernet port (RJ-45 / F connector) receives DC power and provides Ethernet
connectivity with the local network. The Ethernet port connects to the PoE adapter using
a weatherproof CAT-5e Ethernet cable.
Note: The maximum total length of the Ethernet cable is 100 m (328 ft). For example, 95
m from the RDL-3000 to the PoE and 5 m from the PoE to the local network equipment.

2.3

Synchronization I/O Port (PPS)

The PPS port (TNC / F connector) is provided to synchronize the RF transmission cycles
of collocated sector controllers. This feature minimizes inter-sector interference by
synchronizing the transmit cycles of collocated RDL-3000 sector controllers.
This port is software configurable: mode = input, output, or disabled, impedance = 50
ohms, 75 ohms, or high impedance. Multiple RDL-3000 units can be synchronized by
using up to 46 m (~150 ft).of interconnecting synchronization cable.
Important: The synchronization feature must be used at any site where two or more
sector controllers are deployed.
A factory-installed protective weatherproof plastic cap is installed on the PPS port. If this
cap is removed to install a synchronization cable or TNC Tee connector, the port must
be adequately weatherproofed. Refer to the RDL-3000 Installation guidelines for detailed
instructions.
2.4

GPS Antenna Port (GPS ANTENNA)

The GPS antenna port (TNC / F connector) conducts RF signals between the RDL-3000
and the antenna system (ordered separately). This port is provided only on units factory-
equipped with GPS hardware. The GPS antenna can be located remotely from the RDL-
3000 unit by using up to 46 m (~150 ft) of high quality antenna cable. The GPS module
does not set the RDL-3000 internal date/time clock.
Important: A GPS receiver must be provided at each sector controller site comprising a
network of geographically collocated cells.
A factory-installed protective weatherproof plastic cap is installed on the GPS antenna
port. If this cap is removed to install an antenna cable, the port must be adequately
weatherproofed. Refer to the RDL-3000 Installation.
2.5

RF Ports

The two RF ports (N-type / F connectors) conduct RF signals between the RDL-3000
and the antenna system (ordered separately). The RDL-3000 can be operated using a
SISO (single antenna) or MIMO (multiple antenna) system.
Important: Version 1.xx operation is limited to port RF-1. Port RF-2 must be electrically
terminated (connect antenna or RF terminating device) and must be weatherproofed.
