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 weatherproofed.
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.

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
weatherproofed.
RAS Smart Antenna Port (RDL-3000-M)
The RAS smart antenna is a multi-sector high-gain, fast switching, 360° directional beam
antenna for use with RDL-3000-M type subscribers or sector controllers. This is a factory
installed hardware option and operation is enabled by options key.
A factory-installed protective weatherproof plastic cap is installed on the RAS port. This
port must be weatherproofed when the control cable is installed.
