Low Voltage Cutoff for the SPMLTG5000
The SPMLTG5000 will go into a low voltage mode if the battery voltage drops
below 10 volts. It will cease operation and begin alternating between "L" and
"B" on the display to indicated low battery.
Connecting the SPMLTT2500
There are two methods to connect the Lap Timing Receiver to Spektrum
telemetry receivers.
1. For telemetry systems featuring an X-Bus connection, simply connect a
4-pin X-Bus to X-Bus cable between the Timing Receiver and the X-Bus
telemetry connector on the Telemetry device
Tip: X-Bus based timing is
more accurate than RPM based
timing, and includes the option
of lap segments.
2. The timing system can also utilize the RPM input for timing. Use the
included harness to connect the Lap timing sensor to the RPM port or
Lap timing port on receivers such as the SPM4649T. When using this
confi guration, you must connect a 5V power supply to the SPMLTT2500.
