Garmin Update Rate Select Cable

The Garmin Update Rate Select Cable (MPN 010-11824-01) is a specialized interface solution designed for operators who require precise control over GPS antenna output frequency in demanding tactical and military environments. This compact serial communications cable enables users to throttle position update rates on compatible Garmin GHP 19x HVS antenna systems, reducing data transmission overhead while maintaining positional accuracy for navigation, asset tracking, and command-and-control operations. Field professionals in law enforcement, emergency response, and military applications depend on this cable to optimize system performance when bandwidth constraints, power consumption, or data processing limitations require lower update frequencies.

Operating via standard serial communications at 4,800 bps, the Garmin Update Rate Select Cable allows operators to limit antenna output to one position update per second—a significant reduction from the default 10 Hz (10 updates per second) output rate. This functionality proves essential in scenarios where legacy communications equipment, limited telemetry bandwidth, or extended battery life is critical to mission success. The cable's compact 4 x 5 inch footprint and minimal 0.01 lb weight make it an ideal addition to portable GPS systems without adding appreciable bulk or mass to field kits. The direct serial interface approach eliminates the need for external hardware modifications, ensuring straightforward integration with existing Garmin antenna configurations.

Professionals working with Garmin GHP 19x HVS antennas—including tactical teams, surveying crews, unmanned vehicle operators, and emergency management personnel—will find this cable indispensable when standard update rates conflict with system architecture or operational requirements. Installation requires only a direct serial connection to the antenna unit; no additional power or configuration software is needed. The cable's robust design supports continuous field deployment, making it a reliable choice for permanent or semi-permanent tactical installations where reduced data refresh intervals enhance system stability and reduce computational load on connected devices.
