Front Panel Assembly; Pc Board Mounting And Casing - Ramsey Electronics FM-100 Assembly And Instruction Manual

N. FRONT PANEL ASSEMBLY
1N. Align the front panel PC board with the holes in the front panel assem-
bly.
2N. Check the LEDs for proper installation height and positioning. If they
are misaligned, now is a good time to correct that.
3N. Using 3 of the the 4-40x1/4 screws, mount the board securely to the
front panel.
4N. Admire your work up to this point. (WOW!)
O. PC BOARD MOUNTING AND CASING
To make testing of the PC board easier, it is convenient to have the PC board
mounted to the bottom of the case. This keeps down the possibility of wires
crossing or metal objects shorting out across the back of the PC board.
1O. Mount the main board to the bottom of the case making sure the
holes line up with the standoffs in the bottom. Note that you will be install-
ing 5 board screws; the screw under the power switch is not used.
2O. Using one of the pre-made 5 wire jumper connectors, connect from J8
to J7. Make sure pin 1 of J7 is connected to pin 1 of J8. To check this you
can see what pins are connected to the ground plane.
3O. Using the other 5 wire jumper connector, connect from J1 to J3. Again
make sure that pin 1 of J3 is connected to pin 1 of J1.
4O. Connect the 4 pin Molex connector from the rear panel to J11 on the
main board. You can then set the cover in place without having to screw it
down until your initial tests are made.
Now we are getting somewhere! Is it ever tempting to plug it in. But wait, flip
the page first!
