2.0 FUNCTIONS
2.1 OVERVIEW
The 1788-R Remote Controller provides all the functions from the Model 1788’s
Local Block
and
Test
Tone Block
. For complete details on the functions in both these blocks, refer to the Model 1788 User’s
Manual. A quick reference to these basic functions is found in this manual’s Section 1.2 -The 1788-R
Remote Controller at a Glance.
The following two sections provide further details beyond what was in the quick reference for the
Selection and Validation Block
and the
Preset Handling Block
.
There is also a set of Secondary functions; Clip/Lim Metering ballistics, brightness control and software
version display, which is explained in Section 2.4.
2.2 SELECTION AND VALIDATION BLOCK
The upper portion of the 1788-R is used for selecting and validating all Model 1788s in a system chain.
The COMM TEST button initiates a communication test, which verifies the connection status of all
Model 1788s in the system. The COMM TEST button and the VALID LED’s will flash during the test
procedure. At the end of the test, identified units will be indicated by a solid green light in the respective
VALID LED‘s and the COMM TEST button will stop flashing.
Whenever a Model 1788 is added to the system or right after power up, it’s recommended that you run a
communication test, though a communication test can be run at any time just to check status of the
Model 1788s. If changes are made locally on one or more of the connected Model 1788s, the communi-
cation test can be run to upload all new settings.
The VALID LED indicates the communication status of all units identified under the communication test.
A solid green light means valid communication, solid red light means invalid communication. Under
normal operation the VALID LED should never turn red. If the Valid LED should turn red, inspect the
cabling between the Model 1788’s, and the settings in the control block, then rerun the communication
test. After the communication test only the valid units may be selected using the UNIT SELECT button.
Specific units are selected with the UNIT SELECT buttons (illuminates when selected). When a unit is
selected all specific unit settings are transferred to the 1788-R. In Preset Edit Mode the number of units
in a preset can be modified by using the UNIT SELECT buttons. Please refer to the next Section 2.3
–Preset Handling Block.
During the time the remote is communicating (sending or receiving information) the COMM LED will
illuminate. When one or more COMM LED’s are illuminated no new functions can be activated.
The CLIP/LIM indicator illuminates when any one of the eight channels of that particular unit is clipping
or when limiting occurs (if MicLim™ circuit is activated). To determine which channel is exhibiting clip-
ping or limiting, select the unit in question with the UNIT SELECT button and the
Local Block
CLIP/LIM
LED indicator for the individual channel or channels will illuminate. To be able to indicate a short
Clip/Lim event the Model 1788-R has a build-in programmable Clip/Lim memory function. This func-
tion keeps the Clip/Lim LED (both in the
Local Block
and the
Selection and Validation Block
) illuminated
for a certain amount of time. This user programmable function is explained in Section 2.4 - Secondary
Functions.
