Lassen-SK8 Embedded GPS Module C-17
Trimble ASCII Interface Protocol (TAIP)
C.15 PR Protocol
The protocol message (PR) is the method used to control which I/O protocols are active on
each of the two Lassen-SK8 ports. Each protocol can be set to:
• Off
• Input Only
• Output Only
• Both Input and Output
The PR data string format is:
[;TAIP=xy] [;TSIP=xy] [;NMEA=xy] [;RTCM=xy]
Table C-15. PR Data String Descriptions
There are two restrictions to setting protocols.
• RTCM is input only
• TAIP cannot be running on both ports at the same time
*
Note – If a protocol is not implemented within the application, x and/or y will have the
value N, and any set message for that protocol is ignored.
It is possible to turn off all input processing on a port. If this is done, neither TAIP nor
TSIP can be used to change the active protocols. The break sequence must used.
If you do not use battery back-up, all port characteristics will reset to the default after
power is removed.
