Establishing Two-Way Communication - Lexicon MRC V4.0 Owner's Manual Addendum

Establishing Two-way Communication

When configured for two-way communication, the MRC requests parameter
data from the LXP-15 and displays it for editing. The edited values are sent
back to the LXP-15. This back and forth communication, or hand shaking ,
occurs automatically once communication is established between the two
units.
In order to establish communication after the initial connections are made
and both units are turned on, it is necessary to put the LXP-15 and MRC in
the same "state." With two-way communication you have the option of
setting the LXP-15 to the state of the MRC, or of setting the MRC to the state
of the LXP-15. The following procedure describes both options:
1. On the MRC, enter Machine Select Mode by pressing MACH twice.
2. Move the leftmost slider all the way up to select "SYSTEMS PARAME-
TERS" and press ENTER. Use switches 1, 2 and 3 to set MIDI MERGE
to "OFF" for the IN and OUT connected to the MRC as shown below:
If the LXP-15 is connected to IN/OUT1 . . .
IN1 ->
If the LXP-15 is connected to IN/OUT2 . . .
IN2 ->
3. Press ENTER to return to Machine Select Mode.
4. Use the leftmost slider, the MACH button or the keypad to select an LXP-
15 type machine. (Machine #3 is an LXP-15 machine when the MRC is
shipped from the factory.)
5. Confirm that the MIDI cables are connected to the same input/output pair
as the displayed "OUT#".
