MiLLennium GPSCard and Enclosures Guide to Installation & Operation 19
MINIMUM CONFIGURATION
In order for the MiLLennium to perform optimally, the following additional equipment is required:
•
NovAtel GPSAntenna (model will depend on application)
•
NovAtel coaxial cable (note that a conversion is required between the male SMB connector on the MiLLennium and
the female TNC connector on a GPSAntenna)
•
A regulated power supply providing +5 V DC (see Appendix B, Page 33) for power regulation specifications)
•
A 64-pin 0.1" DIN 41612 Type B female connector as an interface for power, communications and signals
•
Data communications equipment capable of RS-232C serial communications
ANTI-STATIC PRECAUTIONS
Electrostatic discharge (ESD) is a leading cause of failure of electronic equipment components and printed circuit boards
containing ESD-sensitive devices and components. It is imperative that ESD precautions be followed when handling or
installing the MiLLennium printed circuit board. See Appendix A, Page 31 for more information on ESD precautions.
Leave the MiLLennium in its anti-static packaging when not connected in its normal operating environment. When
removing the MiLLennium from the ESD-protective plastic clamshell, follow accepted standard anti-static practices.
Failure to do so may cause damage to the MiLLennium.
When you remove the MiLLennium from the original packing box, it is recommended that you save the box and ESD
protective plastic clamshell for future storage or shipment purposes.
REMEMBER !
•
Always wear a properly grounded anti-static wrist strap when handling the MiLLennium.
•
Always hold the MiLLennium by its corners or the RF backplane, and avoid direct contact with any of the
components.
•
Do not let the MiLLennium come in contact with clothing at any time because the grounding strap cannot dissipate
static charges from fabrics.
•
Failure to follow accepted ESD handling practices could cause damage to the MiLLennium.
•
Warranty may be voided if equipment is damaged by ESD.
INSTALLATION PROCEDURE
Installing the MiLLennium typically consists of the following:
1. mounting the MiLLennium in a secure enclosure to reduce environmental exposure, RF interference, and vibration
effects
2. pre-wiring the I/O harness and the 64-pin DIN female connector for power and communications, then connecting
them to the MiLLennium
3. installing the GPSAntenna, then connecting it to the MiLLennium (see Page 14)
4. installing an optional external oscillator (see Page 17)
MOUNTING THE PRINTED CIRCUIT BOARD
Because the MiLLennium is an OEM product, 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
