E.1.2 CONNECTIONS AND INDICATORS
The ProPak II enclosure features front and rear end-caps (Figure E.2 and Figure E.3), each with appropriate
indicator lights and connectors. The front end-cap indicator glows red when power is on, and green when a valid
position is computed.
Figure E.2 ProPak II Enclosure Front End-Cap
On the rear end-cap there are connections for the I/O strobe signals, COM1 and COM2 serial ports, power input
and an RF input from the GPS/GLONASS antenna. There is an LED above each serial port connector. If an LED
glows red, data is being received by the ProPak II enclosure on that port, while if an LED glows green, data is being
transmitted by the ProPak II enclosure on that port.
