PRE-AMPLIFIED ANTENNA. Masterclock GPSPCI

PRE-AMPLIFIED ANTENNA

The GPSPCI requires a pre-amplified antenna. It provides 5 VDC via the center pin of the coaxial for remote power. Warning: Attaching a passive (non pre-amplified) antenna to the

GPSPCI could destroy the GPS receiver module. This is a major repair cost, which is not

covered by warranty.

The unit is tested and shipped with the appropriate cable for the antenna that was ordered.

Should you require a longer antenna cable we recommend that you contact Masterclock so that a properly matched cable and antenna can be supplied.

Although changing the GPS antenna or coaxial cable is not technically difficult, these changes are strictly the usre’s responsibility. We neither warrant nor support operation with any hardware not installed or supplied by us.

ANTENNA COAXIAL CABLE

The coaxial cable should not be crushed, crimped or bent at a sharp angle nor should it be strained by pulling. Any damage to the cable could result in the GPSPCI not functioning properly. If the cable is to be coiled for storage, the coil diameter should be at least 6”.

PROBLEMS – TROUBLE SHOOTING

All GPSPCI units are checked for proper operation before shipment. Unless physical damage is found, the unit has been proven to be functional at the factory.

Please remember for an initial startup at a new location the unit could take up to 30 minutes.

After the unit has acquired satellites at the new location, the startup time is greatly reduced to anywhere from a few seconds to several minutes.

If the antenna (and coaxial cable) has not been damaged and has an unobstructed view of the sky, the power connector is properly installed and the front panel LED follows the startup sequence described earlier (on, off & then on), the unit is working.

If you continue to have problems even after the above precautions have been noted please contact the factory.
