Labs Technologies, Inc. assumes no liability for the customer’s failure to comply with these
requirements.
1.3.1 Legacy GPS Receiver Compatibility
JLT strives to achieve as much compatibility as possible to legacy GPS receivers, however if any
incompatibilities are encountered please reports these to support@jackson-labs.com.
1.3.2 Use an approved Antenna Lightning Protector
The use of an approved, and properly grounded antenna lightning protector on the optional GNSS
antenna connected to the external GNSS receiver is required to prevent damage, injury or death in
case of a lightning strike.
1.3.3 Transmission of synthesized GPS RF signals
It is illegal to transmit simulated/synthesized GPS RF signals. The RF output of the RSR GNSS
Transcoder™ must not be fed to a transmitting antenna, it is only intended to be directly coupled into
an RF input of a GPS receiver using shielded coax cables. The RF output must not be amplified, or
re-transmitted in any way without approval from the appropriate government authorities.
1.3.4 Grounding
To avoid damaging the sensitive electronic components in the RSR GNSS Transcoder™ always
make sure to discharge any built-up electrostatic charge to a good ground source, such as power
supply ground. This should be done before handling the circuit board or anything connected to it, i.e.
the GNSS antenna.
1.3.5 Power Connections
Make sure to connect the DC power to the device following the polarity indicated in Table 3.2 .
1.3.6 Environmental Conditions
This instrument is intended for indoor use. The use of a properly installed GNSS Antenna Lightning
Protector is required. It is designed to operate at a maximum relative non-condensing humidity of
95% and at altitudes of up to 50,000 meters. Refer to the specifications tables for the DC voltage
requirements and ambient operating temperature range.
