Data checksum

Note 1: The sequence number is a count that indicates whether the data in a particular binary message has been 

updated or changed since the last message input.

Note 2: RTCM SC-104 is not a valid protocol for the host data stream.

Data checksum

Note 1: The sequence number is a count that indicates whether the data in a particular binary message has been 

updated or changed since the last message input.

Note 2: Externally supplied temperature measurement. An external temperature input causes the internal temperature 

sensor to be ignored as a source of temperature data.

This message allows the user to set the message 

format protocol which will be used to communicate 

information to and from the receiver through 

the host serial I/O port. Currently, the available 

protocols are binary (with fixed-point numbers) 

and NMEA-0183. Storage for the protocol type 

parameter requires EEPROM. The contents of the 

‘message protocol control’ message are described 

in Table 3-39. 

This message is used to inform the system about 

the quality of the frequency standard being used. 

The contents of the ‘factory calibration input’ 

message are described in Table 3-40
