Setting Data Output And Transmit Memory Data - JRC J-NAV 500 Instruction Manual

GPS Navigator J-NAV500

4.20 Setting Data Output and transmit memory data

When a PC (Personal Computer) is connected to this 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 this unit.
Data transmissions with external equipment can be performed using the data input and output connec-
tions of the power cable.
• Output level
The output level when data is exchanged with external equipment (NMEA0183 data output,
memory I/O) can be set to TTL or RS-422.
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 (version 1.5/2.1 switching
function) are output (For details, see Appendix C, "NMEA0183 Output Sentence and Data
Format.")
• Memory data I/O
The J-NAV500 is to transfer the waypoint and route memory contents of the internal memory to
external equipment and to re-load the memory from the equipment. (See Appendix D, "Waypoint/
Route Plan Data In/Output.")
