NavLink RMC-3 Module

Ideal for use on a buoy or platform to communicate remote monitoring data
300 x 300

RMC-3, a compact monitor and control unit, is optimised for light weight and low power operation. RMC-3 collects and forwards AtoN data to the NavTERM® software. RMC-3 can be installed, for example, on a small isolated buoy with limited battery capacity, yet still provide reliable full-time monitor and control for all AtoN equipment.

  • Features
    • Stainless Steel Enclosure - A 316 stainless steel (NEMA 4X, IP65) enclosure is standard to the RMC-3 and is ideal for remote environmentally harsh locations. Enclosure will provide protection from surrounding electromagnetic fields that could damage internal electronics.
    • Configured to Monitor and Control – Tideland can configure any combination of AtoN connections and attach AtoN devices up to RMC-3 built-in limits. All configured input connections are field selected to report on exception with Authority parameters establishing AtoN warning and alarm status.
    • Built-In Lightning Protection - All circuitry is lightning protected and RMC-3 comes provided with an earth-grounding stud.
    • Inputs/Outputs - RMC-3 contains four analog and four digital input channels for external input channels for general monitoring use.
    • Six Communication Channels - RMC-3 has channels available to handle any communications requirement. For example, one channel may be used for on-board GPS option.
    • In-The-Field Diagnostics - NavLINK ’s Field Configuration Utility (FCU) allows the setup, upgrades, diagnosing and fault finding of the RMC-3 and its devices in the field using a laptop computer.
    • Communication Modules - The NavLINK communication modules serve as the hardware level port between the AtoN monitoring system and monitor and control location and/ or Authority base station. Communication modules support the following mediums: VHF/UHF, dial-up modem, IP, direct, cellular telephone, satellite or AIS information system.
