Activating Monitor Mode

Monitor mode refers to the rudimentary operating system hard-coded into the ProPalette
on-board microprocessor. It provides base level control and communication between the
ProPalette unit and the host computer through the ProPalette serial port.
Monitor mode can be activated by any of three methods: (1) front panel buttons, (2)
digital board jumpers, and (3) LCD menu.

Activating Monitor Mode Via Front Panel Buttons

Note: Monitor mode can be activated via the front panel buttons only on
ProPalette models with digital board 1F5570A Is06 or later
(generally ProPalette models 8035, 8045 and 8067, and ProPalette
7000 and 8000 models with upgraded digital boards). This method
also works with earlier digital boards if EPROM U103 has been
upgraded with the ProPalette ROM v548 P/N 102423.
To activate Monitor mode via the front panel buttons:
1 Turn the ProPalette power switch to off.
2 While pressing and holding the scroll up and scroll down buttons, turn the
power switch on.
3 Release the scroll up and scroll down buttons.
Note: This method also disables the watchdog timer.
To return to normal mode, turn the system off and back on or press the reset button.

Activating Monitor Mode Via Digital Board

To activate Monitor mode via the digital board:
1 Turn the ProPalette power switch to off.
2 Jump J3-6 and J3-8 on the digital board to ground. (All pins along the bottom
of J3 are at ground potential.)
3 Turn the ProPalette power switch to on.
Note: The LCD panel does not operate when you activate
Monitor mode in this manner, so there is no indication that
the mode is active. You must run a terminal emulator for
the serial port to verify that the EEPROM has control.
Return to normal mode by turning the system off, removing the jumpers, and turning the
system back on.
