Time Code generator was outputting data in the wrong time code generator.

Solution
Need to use a hperterminal client. Interface settings are 19200, 8 bits, No parity, 1 stop bit, and no flow control. Should receive data every second if connect correctly. You may also need a Null Modem
Send the code: +00 to set a no time zone offset. Check that the time zone offset is correct by sending S. The S (Status) should return “S+00112” The 00 indicates no time zone offset. If the return is “T” the last 6 digits before that lat/long will show the time. Make sure that time is the current UTC time.
