Hi, The RMC message contains a status parameter, this is either V=data not valid or A=data valid. You need to wait until you read an A in the RMC, before this you will not get a ZDA message even if you have enabled it.
To enable RMC messages: $PSRF103,04,00,01,01 Once you get an A in the RMC message you should then enable ZDA messages: $PSRF103,08,00,01,01 You will need to calculate and append checksum to the enable messages which I haven't done. The ZDA message contains a UTC time, also day, month and year, local time offsets to UCT are also included. The time is the details the 1PPS pulse that has just occurred.
