Assembly and Disassembly
Should you require access to the KPC-3 Plus to reposition jumpers or for other
purposes, disassemble as follows:
1. Turn off power to your KPC-3 Plus and remove all cables from the unit.
2. Using a small phillips screwdriver, remove the two (2) case screws (located on each
side of the case) completely.
3. Remove the top cover from the unit. NOTE: In most cases, no further disassembly of
the unit is necessary. Only if you need to change a wire jumper or solder
connections to the PC board should you continue with disassembly of your KPC-3
Plus.
4. Remove the four (4) hex nuts on the rear panel that secure the DSUB-9 and DSUB-
25 connectors to the case.
5. Remove the two (2) screws securing the front panel to the case.
6. Remove the front panel.
7. Observe proper static protection precautions and gently lift the front edge of the PC
board to clear the front of the case.
8. Pull the PC board forward to remove the PC board from the case.
To reassemble, reverse the procedure above.
Hard Reset
The hard reset process is provided to re-initialize the KPC-3 Plus to its default values.
This process may become necessary should operational problems be encountered or
when upgrading your firmware to a new version. The readout specified in step 5 below
will be legible only if your terminal baud is 1200. At other terminal baud, a reset will
occur. However, no display readout will be observed. This procedure is performed as
follows:
1. Open the KPC-3 Plus by removing the two (2) case screws on the sides of the unit
and lifting the cover.
2. Locate the Hard Reset jumper (J11). Jumpers are appropriately labeled on the PC
board. Refer to the parts location diagram for help in locating them.
3. Place the jumper on both pins.
4. Apply power to the KPC-3 Plus.
