Upgrading the C104 Programmer
The Inovonics C104 programmer becomes the FA104 programmer by installing components included in the the F104
upgrade kit.
Contents of the kit: Tools needed:
1 transmitter programmming cable small (#1 or #0) phillips head screwdriver
1 microprocessor small slot screwdriver
1 1x3 elastomeric keypad element small paper clip or .032" wire
3 blank keys soldering iron
1 3-pin right-angle header solder
1 graphic overlay label
Upgrade Procedure:
1. Replace the C104 graphic label with the FA104 graphic overlay.
2. Place the C104 Programmer upside down on the workbench.
3. Use a small slot screwdriver to release plastic catches at bottom edge and carefully remove back cover.
4. Use a small phillips screwdriver to remove the single screw fastening the PCB board to the front hosing cover.
Carefully lift the PCB away from the front cover. This exposes the keys, so be careful not to accidentally dump
them.
5. Place the 3 blank keys in the unused cutouts in the front cover. Set the front cover aside.
6. Solder the 3-pin header on the PCB as shown. Insert from the component side of the board. The "short" legs go
through the board. Tip: for maximum joint strength, solder the through-hole pins on pads on both sides of the
board. Solder on the component side first, to tack the header in place, then turn the PCB over and put good joints
on the backside pads. Inspect the solder joints carefully for good flow, and make sure that there are no solder
bridges between pads. Finished joints should look "bright and shiny".
7. Insert the paper clip or wire into the holes on the front side of the elastomeric keypad and press the mounting pegs
through the mounting holes in the PCB.
8. Very carefully remove the microprocessor from the socket. If you don't have a special tool for this procedure, use a
small flat screwdriver under the chip body to gradually pry the microprocessor legs out of the socket.
9. Remove the upgrade microprocessor from the anti-electrostatic foam and carefully insert it into the socket. THE
MICRO IS ORIENTED WITH THE POLARIZING NOTCH TOWARD THE CENTER OF THE BOARD. A good
method is to insert all the pins on one side of the socket, then to carefully press the other side in. After insertion,
look closely for bent or buckled leads.
10. Re-assemble the programmer. Tip: when assembling the housing, hook the top hinges first, then snap the bottom
latches into place.
