High Performance Field Mutiplexer
Model PTS-9MX

The PTS-9MX field multiplexer allows for a cost effective means to multiplex a number of incoming signals into one outgoing signal for transmission. This allows for the reduction of the number of dedicated repeater stations required to transmit data to a central location.

The unit can be ordered in a 2, 4, 6, 8, and 10 channel configurations. The standard configuration includes a passive attenuator for each channel allowing the user to easily adjust the incoming signal amplitude for each channel to attain equalization prior to the multiplexing operation.

To further enhance incoming signal conditioning, a variety of optional filters or line amplifiers modules can be used on any or all channels. Each channels standard or optional signal-conditioning module utilize gold plated connections for field reliable long-term noise free connections. The PTS-9MX is very low power, easy to use, and easy to field repair or upgrade. The rugged and well-shielded enclosure makes it perfectly suitable for portable and rapid deployment applications in addition to permanent monitoring. The unit is conservatively designed and includes ample transient suppression. Power output jacks allow radio receivers to be directly connected to the multiplexer.

The multiplexed output can also be directly connected into the PTS-3BG field telemetry station. Other system components include lightning suppression systems (Model LPS-x), external signal band pass, high pass, or low pass filters (Model TC-70x), and line amplifier (Model TC-80x), and central site digitizing and recording systems (Model DAS-6102PC), and analysis software.
