MX521A/MX521B/MX525A/MX575C/MX575D Antenna setup
In the initial commissioning of the MX61x navigation system or when a new MX antenna is
installed, you need to manually select the position data source of the MX610/MX612 when
using the MX521A, MX525A, MX575C and MX575D smart GPS antenna sensors. They are
normally connected via the NMEA 0183 ports #3 and #4 of the MX61xJB junction box.
Use the manual selection procedure below:
1. Press the MENU key.
2. Highlight the Data sources menu then press ENT.
3. Scroll to Position submenu then press ENT.
4. Scroll to MXJB-NMEA3 [xxxxx#], where NMEA3 is Port 3 and xxxxx# is
the serial number of the source as indicated on the junction box PCB
then press the ENT key to place a check mark.
5. Press CLR key.
6. Scroll down to RTCM signal, press ENT.
7. Scroll to MXJB-NMEA4 [xxxxx#], press ENT to place a check mark.
8. Press the CLR key.
9. Scroll down to RTCM corrections, press ENT.
10. Scroll to MXJB-NMEA4 [xxxxx#], press ENT to place a check mark.
11. Press the CLR key to bring back the Quick Menu or any hot key to exit.
12. End of setup procedure.
Setting the Antenna Port Baud Rate
If the CDU fails to detect the MX521A/MX525A/MX575C/MX575D antenna connected to
NMEA3 of the J-Box, do the following:
1. Press the MENU key to bring up the quick menu.
2. Scroll to Data sources, press ENT.
3. Select Position, press ENT.
4. Deselect MXJB-NMEA3 as source of position.
5. Press the CLR key until the Settings menu appears (or press the MENU then scroll to Tools &
Setting, press ENT).
6. Select NETWORK, press ENT.
7. Scroll to Device List, press ENT.
8. Scroll to MXJB-NMEA3, press ENT.
9. The Configure button will be highlighted, press the ENT key.
10. Scroll to Baud rate, press ENT.
11. Scroll to 4800 (or 19,200) baud, press ENT.
12. Press the CLR key several times to exit to Settings menu.
13. Select Network, press ENT.
14. Select Sources, press ENT.
15. Scroll to Position, press ENT.
16. Select MXJB-NMEA3, press ENT to leave a check mark.
17. Press the CLR key to exit.
18. Verify if position L/L is displayed in POS1 screen.
¼ Notes:
1. If MXJB-NMEA3 (Port 3) is selected as position source the “Configure” button will not be avail-
able. To configure Port 3, it has to be deselected first as source.
2. Possible baud rates are 4800 or 19,200. When both antenna and J-Box port 3 are at the same
baud rate (i.e. 4800), the J-Box sends a setup command to change the antenna baud rate to
19,200. Port 3 in turn switches itself to 19,200 baud automatically. If this fails to happen, you
may have to manually reset the baud rate of the Port 3 of the junction box to 19,200 (see setting the antenna port baud rate for procedure).
