Home Forums General Discussion Technical Questions Kone Ecospace

I have a Ecospace that is givimg 1301 and 1101 faults which is a loss of serial link communication. I checked all the wiring and it is good, just not sure how to test which board in the serial link is bad. This is the link that goes from the cpu to the cartop to the cop and to the door board.Anyone know a test for this issue? Thanks

If its a resolve controller it's a bad cob board in cop , you can try to Lon download
5-7-1, sometimes doing it a few times will bring back the board if it is a ecospace . But normally you only have a cob board on older ecospace controllers with innovation, or kone 220 series buttons .

The com boards in the cop have a little red light on them, that lites when it goes bad. Happens right after warranty expiration.
