EFIS LITE with RDAC-XF

Post by Erkki »

I have just installed EFIS LITE with RDAC-XF, SP6 and SP7. 120 ohm resistors are installed in SP6 in fuselage aft of cockpit and in EFIS LITE. Now EFIS reports that "Rdac is not available". Green light in Rdac is flashing 1Hz. Should I install 120 ohm resistor to Rdac or what is your advise?

Your RDAC is not seeing the EFIS (it does a double flash if it can receive messages from the EFIS). So something is wrong with that link from EFIS to RDAC. I assume your SP 6 is working - check for the double flash as well ?

I just checked the whole system and both SP6 and SP7 are douple flashing, RDAC single flash. I also checked wires and connectors and they are ok. Few days ago I updated the EFIS, is there anything else I can do?
