GNS-430W/530W - EFIS - Autopilot - ARINC Interface Troubleshooting
These tests must be done on the screen that is directly wired to the AF-ARINC
module and 430W RS-232 Aviation format serial port.
1. Verify that the EFIS is communicating with the AF-ARINC module
a. Verify the ARINC software version from the following EFIS menu:
[CHECK] -> [MAINT.] -> (ABOUT)
If the EFIS is displaying an ARINC Version number, the EFIS is
communicating with the ARINC module and you can move to Step 2.
b. Verify the EFIS serial port settings from the calibration menu:
[CHECK] -> [MAINT.] -> [ADMIN] -> [CALIB.]
1. Admin Settings
Verify that you have the same serial port number configured to
ARINC that you physically wired the module to. This is normally
Serial Port #4, although it does not have to be.
c. Verify that the AF-ARINC module does not have old software.
From the Calibration menu select:
1. Admin Settings
21. System Maintenance
3. Upgrade ARINC Software
Cycle the power to the ARINC module (Turn OFF and ON Master Switch) to see if the EFIS
can detect the module at the slower speed. If the EFIS detects the AF-ARINC module you will
need to insert an SD card with the updated ARINC software to program it.
d. Verify that you have power to the AF-ARINC module.
Remove the top AF-ARINC cover by removing the four top
cover screws. If the Green LED is lighted then the module has
power. If the LED is not lighted use a volt meter to verify that
the AF-ARINC DB-25 connector has power.
Pin 1 (12-28) Volts
Pin 3 Ground
If the connector has power and you have not wired the connector backwards! Call AFS for a
replacement AF-ARINC module.
e. Verify that you have wired the serial port TXD and RXD to the correct pins on both the EFIS
and ARINC connectors.
