3.4.1 MOUNTING THE PRINTED CIRCUIT BOARD
The MiLLennium-GLONASS GPSCard is an OEM product and therefore the printed circuit board is not enclosed
in a housing structure. This allows flexibility in creating a mounting environment to suit particular product and
marketing requirements. The mounting and enclosure must provide the following:
•
mounting of external connectors
•
protection from hostile physical environments (e.g. rain, snow, sand, saltwater, extreme
temperatures)
•
protection from vibration conditions
•
electromagnetic shielding to protect from hostile RF environments (e.g. nearby transmitters)
•
electromagnetic shielding so that the final product itself conforms to RF emissions guides
•
protection from ESD
The MiLLennium-GLONASS GPSCard can be screwed in place, held by card rails, or both. Please see Appendix
B, Page 49, for mechanical drawings.
For some applications the ProPak II Enclosure, Page 59, or the PowerPak II Enclosure, Page 73, in the chapters
following, are ideal. They are enclosure kits that come complete with mounting and wiring interfaces, and allow
immediate operation of the MiLLennium-GLONASS. The two enclosures are designed for rugged operating
environments.
3.4.2 PREPARING THE DATA, SIGNAL & POWER HARNESS
The wiring harness serves the following interconnect functions:
•
provide access to COM1 and COM2 serial communications ports
•
provide access to input and output timing strobes
•
provide power input(s)
•
provide access to control signals
A 64-pin / 0.1" / DIN 41612 / Type B / female connector (e.g. Harting #0902 164 6825, #0902 264 6828, or
equivalent) is required to interface with connector P1 on the MiLLennium-GLONASS GPSCard (see Figure 3.2,
Page 20). The connectors you choose for interfacing to the power source(s), COM ports, and strobes will depend
on your external equipment requirements. Figure 3.2, Page 20 shows the pin names and locations on connector
P1.
NOTE: See Table B.2, Page 53, for descriptions of the function of each connector pin.
WARNING: The MiLLennium-GLONASS GPSCard will suspend operation if voltage supplied falls outside
input range +4.875 to +5.250 V DC.
