Using MinPad
• Solid green + red flashes every 2 sec. – Modem is registered in
network and is in waiting mode.
• Solid green + red flashes every 0.5 sec. – Modem is during a call
and receives/transmits data.
Information Modes
The Maxor has two information modes: Normal and Extended Information
Mode (EIM).
Normal
In normal mode, the STAT LED indicates the number of tracked
satellites and the position's computation status.
Extended Information Mode (EIM)
Extended Information Mode is used for receiver testing purposes. In
this mode, the receiver continues to work as usual, but the STAT LED
indicates the following "extended" information:
• Delimiter - an easily distinguishable double-blink that shows the
overall status of tests performed in EIM. The STAT LED color for
delimiter is calculated from the colors of other STAT LED blinks.
–Orange: at least one blink is orange.
–Red: no orange blink and at least one red blink.
–Green: all other cases.
• Sufficient data for position computation.
• GPS S/N ratios are good (Table 4-2).
• GLONASS S/N ratios are good (Table 4-2).
• Oscillator's frequency offset is less than three ppm.
• Oscillator's Allan Variance is better than 2.7e-10.
• Continuous tracking time is more than 15 minutes.
