I'm a Maintenance Mgr at a hotel. Currently we have one "Front Desk Unit" (it's what programs the key cards for the doors) When ever a door lock has issues I need this unit to reprogram the door lock. Normally borrowing the FDU from the desk isn't a problem. Except in the summer when it's busy. If I have the unit, nobody can get a card for a door.
A few years ago our unit when out. Ordered a new one. Now instead of borrowing the new one, I wanted to have my own, but being denied another FDU from the owners (around 700 bucks) I looked at the bad one.
I think there is a "fuse" that is bad. Not sure if it is a fuse or what it's called. Here's a few pics.
Here's the main unit.
Super close up of the circuit board.
In the picture above, I can plug the power supply. With my multi meter on the ground, I get around 9V on the top side of F1 but when I test the bottom side, I dont get a reading.
If I Ohm test this, I dont get a reading at all. I get the same results on D29 circuit but fail to see where that goes. Unless it goes in between the circuit board.
What would the D29 & F1 components be called so I can order them?
