We have 2 Miprom HS units that we have acquired from schindler, the cars work great, the only problem is that we are unable to access the LCE cpu interface to check faults, give car calls, etc. you can only see the cars position on the interface, that is all. We have other units on service, where you can interface with the cpu and check faults, change parameters, etc. I am sure schindler has locked us out of these units, does any one have any ideas as to how to restore the units?
