EM-506 High Performance GPS Module ZDA - Time and Date This message is included only with systems which support a time-mark output pulse identified as "1PPS". Outputs the time associated with the current 1PPS pulse. Each message is output within a few hundred ms after the 1PPS pulse is output and tells the time of the pulse that just occurred.
EM-506 High Performance GPS Module NMEA Input Command A). Set Serial Port ID: 100 Set PORTA parameters and protocol This command message is used to set the protocol (SiRF Binary, NMEA, or USER1) and/or the communication parameters (baud, data bits, stop bits, parity). Generally, this command would be used to switch the module back to SiRF Binary protocol mode where a more extensive command message set is available. For example, to change navigation parameters.

LLA Navigation lnitialization ID: 104 Parameters required to start using Lat/Lon/Alt This command is used to initialize the module for a warm start, by providing current position (in Latitude, Longitude, Altitude coordinates), clock offset, and time. This enables the receiver to search for the correct satellite signals at the correct signal parameters.
EM-506 High Performance GPS Module Use this command to enable development debug information if you are having trouble getting commands accepted. Invalid commands will generate debug information that should enable the user to determine the source of the command rejection. Common reasons for input command rejection are invalid checksum or parameter out of specified range. This setting is not preserved across a module reset.
