Issue
Cannot download bin file to a MIP upgraded 7700 controller
Environment
PCU 7700 MIP
Cause
RAM memory may need to be cleared.
Resolution
To clear RAM memory on the MIP card:
- Disconnect Power (failure to do so will permanently damage the device)
- Determine how many RAM chips are on the MIP card
- Each RAM chip has a corresponding Capacitor. C4, C5 and C6 ( you can have up to 3 RAM chips)
- Short across each capacitor 1 at a time
- Reconnect power
