The following step-by-step instructions will first assist you in configuring the Model 1788(s) into a
system so they will be recognized by the 1788-R and then you are guided through a comm test proce-
dure. Finally, we show how presets are created, loaded and changed.
On the Model 1788
1. Tap the LOCAL CONTROL button (so it illuminates) on all connected Model 1788s.
2. On the first Model 1788 in the chain, press SET PORT to select RS-232 or RS-422 (depending on
port used to connect to 1788-R). Select the RS-422 for the reminder of units in the chain.
3. Toggle the SELECT button until the baud rate of 19.2kHz is displayed in the status readout.
4. Press the MIDI button until the LED marked “Chan.” illuminates, then select MIDI channel 1 by
toggling the ADJUST button until the status readout displays “ch1”. All units must be set to chan-
nel 1.
5. After the channel has been selected on all units, press MIDI button once again so that the LED
marked “Dev.” is illuminated. Select Device 1 as the first unit in system by toggling the ADJUST
button until the status readout displays “dev1”. For each remaining Model 1788 in the chain follow
the same procedure and select “dev 2”, “dev 3” and so on.
On the 1788-R
6. Tap on the COMM TEST button so it illuminates. The 1788-R will now perform a series of tasks
with all connected Model 1788s. The completion of the communication test is indicated by the illu-
mination (green) of the VALID LED for all connected units and the COMM TEST button will no
longer be lit. The COMM TEST button will flash during test procedure. At the end of comm test,
unit 1 is selected as the default unit. All settings from each connected Model 1788 are loaded into
the 1788-R during the Comm Test.
7. Select desired unit with the corresponding UNIT SELECT button. Make sure the VALID LED is
green. Only a validated unit may be selected.
8. The Local Block now reflects the settings for that specific unit. Changes to that unit can now be
made directly from the 1788-R.
9. Continue steps 7 & 8 with all connected units and make any desired changes to each unit.
10. To save all settings of the units in the system, you want to create a preset. This is accom-
plished by dialing in the desired preset number with the SELECT knob and pressing the SNAP
SHOT button. This will copy the created preset number into the current (loaded) display. The three
preset status LEDs will now reflect the status of the newly selected preset.
11. Repeat steps 7-10 to create/edit presets at will.
12. To load already created presets into the connected 1788-R, dialup the desired preset number so
it is displayed in the NEXT display. To load that preset (making it the CURRENT preset), press the
LOAD button. The selected preset number will now be displayed in the CURRENT display panel.
Note: The Comm LEDs for all the connected units are illuminated when presets are
loading. You must wait for the LEDs to turn off before proceeding. For more info on
working with presets refer to Section 2.3.
