Making GPS Connections
To connect a GPS signal to the TimeProvider, you must install a GPS antenna with
either the standalone TimeProvider Interface Unit (TPIU) and an IMC or the
integrated IMC/TPIU card using the procedures in this section.
Installing the GPS Antenna
These installation procedures are to be used in support of local company
procedures and the Installation Job Specification.
Prior to installing the antenna, you should plan the site, antenna location, lightning
suppressor location, cable route, and all other details. Use Figure 3-19 as a guide to
locating the antenna.
