GPS Receiver is Not Recording Data

The Data Log LED on the front panel of the GPS Receiver Module will blink green
each time an epoch of data is recorded to memory. Examining this LED you
determine that the receiver is not logging data to memory. Follow the procedures
below to determine the cause of this problem.
Step 1. Is the GPS receiver tracking satellites?
The GPS receiver must first be tracking satellites before it can log data to memory.
Check the SV/Power LED on the front panel of the Z-Max GPS Receiver Module to
determine if the receiver is tracking satellites.
Receiver is not tracking satellites
Refer to the above troubleshooting item on satellite tracking to try and determine
the problem.

Go to step 2 below.
Step 2. Is the SD memory card installed in the GPS Receiver Module?
The Z-Max GPS receiver logs data to a removable SD data card. The data card must
be installed in the Z-Max GPS Receiver Module for the receiver to log data. Check to
ensure that the data card is properly installed. If the Z-Max is powered on without a
data card, a warning message should appear across the front panel display.
Data Card Not Installed
Install an SD data card into the receiver.
