The TX312 has registers used to store information about errors that have
occurred. The total number of errors is stored, up to 255. Also stored is the
command that was issued when the error occurred and a code specific to the
type or error.

Internal fault codes are stored. When the command that failed is listed as 31
(0x1F), the error condition is an internal error with the TX312. The datalogger
receives the error code as a hex value and converts to decimal. Decimal values
are placed in input locations.

The error codes are very important information if the DCP experiences trouble
during operation. Generally a GPS time synchronize fault should not cause
concern, but a GPS fault may cause a scheduled transmission to be missed.
The data will be sent on the next transmission if the instruction appends data to
the self-timed buffer.

The internal TX312 errors provide critical information for diagnostics. Error
codes are return in hex format when using SatCommand software. Error codes
are returned in decimal format when using the datalogger.

Error code 16 (0x10), message abort due to PLL, is a hardware failure of the
phase locked loop circuit. Repeated PLL failures can not be rectified in the
field.

Error code 17 (0x11), message abort due to GPS, indicates the transmitter
aborted a transmission because the required GPS information was not available
at transmit time. Usually the transmitter will transmit on the next transmit
time. Check GPS antenna placement and GPS antenna type. See Section 6.3
for more information regarding the GPS antenna.
