CIRCUIT DESCRIPTION
The location data is calculated by the GPS unit and is then
sent to the transceiver via the RXD terminal of the universal
connector.
When the transceiver is turned OFF, the GPS unit enters
to backup mode and the power is supplied by the internal
rechargeable lithium battery.
When the transceiver is turned ON, the GPS unit enters to
normal operation mode and the power is supplied from the
transceiver via the 5M terminal of the universal connector.
While the transceiver is turned ON, the internal rechargeable
lithium battery charges.
It takes approximately 70 seconds to calculate the location
data when the GPS unit is "cold started" (full initialization).
This PCB does not have the LF silk screen, but it
is a lead-free solder corresponding product.
