This document explains how to connect to the NI 9467. Before you begin, complete the software and Note hardware installation procedures in your chassis documentation. The guidelines in this document are specific to Note the NI 9467. The other components in the system might not meet the same safety ratings.

For Division 2 and Zone 2 applications, Caution install a protection device between the external power supply and the Vsup pin. The device must prevent the Vsup-to-COM voltage from exceeding 50 V if there is a transient overvoltage condition. Special Conditions for Hazardous Locations Use in Europe and Internationally The NI 9467 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO Certificate No.
Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your local regulatory rules. To ensure the specified EMC performance, Caution operate this product only with shielded cables and accessories.
NI 9467 Overview The NI 9467 is a stationary GPS timing module for C Series platforms. It provides accurate timing and geographic location information to the C Series host, which enables synchronization of C Series systems. Start-Up Behavior At start-up, the NI 9467 automatically begins determining its location through a process known as self-survey.
(for example, the receiver must not use signals from satellites marked as unhealthy) and contains coarse orbit information. The GPS satellites broadcast the ephemeris and almanac data every 30 seconds. Therefore, it usually takes approximately 30 seconds for it to receive the ephemeris and almanac data and start computing location and timing fixes.
Maximum Cable Length Maximum cable length depends on the GPS antenna gain and the cable’s loss per unit of distance. National Instruments recommends a GPS signal strength of between -135 dBm and -120 dBm at the NI 9467 SMA input. GPS signal strength on the Earth’s surface is typically -130 dBm.

Typically, when a system is in sleep mode, you cannot communicate with the modules. In sleep mode, the system consumes minimal power and may dissipate less heat than it does in normal mode. Refer to the Specifications section for more information about power consumption and thermal dissipation.
