Tetracam's FirePoint™ 100 GPS is a space-based satellite navigation system that provides precision location and time information anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.
The FirePoint™ 100 GPS is configured to operate with the following Tetracam systems:
ADC – FirePoint provides GPS coordinates via RS232 input
ADC Lite – Provides GPS coordinates via RS232 input
ADC Air – Provides GPS coordinates to button box RS232 input
ADC Micro – Provides GPS coordinates to button box RS232 input
Micro-MCA
or Mini-MCA – Provides GPS coordinates to button box RS232 input
SensorLink ™ – Provides GPS coordinates to laptop equipped with SensorLink via USB interface
FirePoint™ 100 GPS Contents:
FirePoint™ GPS Module and Case
RS232
male-to-male serial interface cable
+12 V Power Supply
cable, 2.5 mm Plug
to Un-terminated
wires
FirePoint™ 100 GPS Connectors:
Power: 2.1 mm DC Power Jack, positive on center, ground on shield 
3.5mm Phone Jack:
RS232 - Tip: TX output from FirePoint connected to RX input to
the camera,
RS232 - Ring: RX input to FirePoint connected to TX output from
camera,
RS232 - Ground on sleeve (see GPS Cable PDF).
Note: If this jack is taken apart to connect to
unterminated pins on, for example, the ADC Micro, connect the
TX output from the FirePoint device on the phone jack tip to
the RS232RX input (GPS In) on Pin 8 of ADC Micro
Interconnection Pins. Connect the RX input to the
FirePoint device on the jack ring to the RS232TX output on Pin 7
(Serial Output) on ADC Micro Interconnection Pins and connect
the Ground on the jack sleeve to Pin 15 System Ground on the
ADC Micro Interconnection Pins.
Mini USB: For power and data when connected to a PC only (for SensorLink).
This interface will not work when connected directly to the
Tetracam camera
FirePoint™ 100 GPS Specifications:
Power: The FirePoint™ GPS will typically be connected to the same + 12 VDC power source as is used by the camera. The FirePoint™ GPS will operate on any voltage between + 7.5 VDC to + 30
VDC.
Baud rate: By default, the FirePoint™ GPS is configured at the factory for 4800 baud, 8 data bits, 1 stop bit and no parity to match the default serial interface settings of Tetracam cameras. The FirePoint™ GPS may be reconfigured by advanced users to operate at baud rates up to 38400 baud.
The selected baud rate must match that of the system with which it communicates.
Protocol: The FirePoint™ GPS is configured to output the standard NMEA "GGA" sentence. This sentence is emitted once per second and contains the following fields:
Resolution: 2.5 meters Weight: 45 grams (0.1 pound) Dimensions shown in mm and [in]:
Powering the FirePoint™ 100 GPS:
There are two options to power the FirePoint™ 100 GPS
1. Power supply input on the DC Power Jack between 7-30V. Positive in the center.
2. Via Mini USB connection (PC connection only).
Interconnecting the FirePoint™ 100 GPS:
The illustration below shows how to interconnect the FirePoint™ 100 GPS to:
1. ADC or ADC Lite
2. ADC Air, ADC Micro or Mini-MCA
3. Laptop running SensorLink
