JLR-10 GPS Compass
4.21 Setting Output Level and Transmitting/Receiving Memory Data
When a Personal Computer (PC) is connected to Display Unit, the output level must be set to TTL when data is input
from the PC since an RS-422 setting could damage the PC and Display Unit.
Data transmission/reception with external equipment can be performed using the DATA IN/DATA OUT lines of
the Display Unit Data Cable (option).
• Output level
The output level can be set to TTL or RS-422 when data is exchanged with external equipment (NMEA0183
data output, memory data I/O).
The output level must be set before data is exchanged with external equipment.
The following two types of data are supported in communications with external equipment.
• Output data
GPS data conforming to the NMEA183 format and navigation data are output (For details, see Appendix 4,
“Data Output”)
• Memory data I/O
The JLR-10 can transfer the waypoint and route memory contents of the internal memory to external
equipment (PC) and re-load back from to the JLR-10. (See Appendix 5, “Waypoint/Route Plan Data In/
Output.”)
