Issue
Problem with downloading bin file with more than one door defined causes second set of doors to deny reads.
Bin files connected to this issue are 3.24, 3.25, 3.26
Environment
TAC I/Net Seven using Access Control. SCU 1284 configured with two doors. (Dip Switch 6 ON gives double address)
Cause
Bin file failure to download with double address setting.
Resolution
On an SCU, an SCU is configured for 4 doors. 2 of those doors are working. 2 of the doors on the SCU are not working.
Only thing that has changed is the SCU was downloaded with a new bin file. Nothing in door configuration was changed, no dip switches were altered.
Solution:
Find out which doors were not working, (probably the second two doors like 0104)
Go to Edit/controller/MCU Configuration and Set those doors to Internal, and then download the SCU with the bin file again.
Go to Edit/controller/MCU Configuration and Set the doors back to DPU.
