Assembly and Disassembly
Should you require access to the MT1200 to reposition jumpers or for other purposes,
disassemble as follows:
1. Turn off power to your MT1200 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 MT1200.
4. Remove the four (4) hex nuts on the rear and front panels that secure the DSUB-9
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/Self-Test
The hard reset process is provided to re-initialize the MT1200 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 19200. At other terminal bauds, the displayed
messages will be garbled, or no display readout will be observed. This procedure is
performed as follows:
1. Open the MT1200 by removing the two (2) case screws on the sides of the unit and
lifting the cover.
2. Locate the Hard Reset jumper (J1). Jumpers are appropriately labeled on the PC
board. Refer to the parts location diagram for help in locating them.
