MC-2.5 Receiver Box Functions
Three LED indicators on the MC-
2.5 Receiver Box provides status on power, satellites, and radio signal
(Figure 1-13 on page 1-12). Two function (FN) buttons provide
diagnostic and reset for the internal receiver boards.
• Radio RX LED – radio status indicator. This LED blinks green
when receiving data from the Base Station, typically once per
second.
• Main LED and FN Button – power and satellite indicator.
– When the MC-2.5 Receiver Box is hooked up to power, but is
not connected to a GPS antenna and therefore not tracking
any satellites, only the red LED blinks.
– When the MC-2.5 Receiver Box is attached to a GPS antenna,
green blinks indicate the number GPS satellites being tracked
while red blinks indicate GLONASS satellites. A pause
precedes each repetition of blinks.
– Pressing the FN button changes the Main receiver board’s
information mode between Normal Mode and Extended
Information Mode. See below for details.
