2.4
Wiring
If the ST100 will be line-powered, proper installation and field wiring practices are important to follow. Users and
installers should familiarize themselves with the requirements of all applicable codes, laws, and standards.
2.5
Noise Sources
Electrical noise is an important consideration in any installation of the ST100. When possible, sufficient physical
separation should be maintained between electrical noise sources and the ST100.
2.6
Obstructions
If the internal ST100 Bluetooth and/or GPS/Satellite antennas are used, care should be taken as to what is placed above,
below, and around the short edges of the PCB. The short edges are where the ST100 internal antennas are located. For
best performance, the ST100 should have an unobstructed view of the sky, either outdoors or in a glass-enclosed area
such as a vehicle dashboard.
2.7
PCB Antenna
The ST100 has 2 PCB Trace antennas on the board for Satellite and Bluetooth transmissions. These are the default
antennas for the ST100.
Regulatory Note:
The ST100 was certified using its Satellite and Bluetooth PCB Trace antennas. The use of any external
antennas will require additional regulatory testing plus approval from Globalstar Engineering.
