INTRODUCTION
This manual for the Bel Remote Controller should be read in conjunction with
the manual for the target processor. These are currently Bel 2120B and Bel 2140B
The Bel remote communicates with the target processor using an RS422 port and can
control up to 16 independent units. (Addresses 1 to 16)
Features
The Bel remote controller carries momentary action switches for controlling
matrix switching, inversion, muting and mode changes. Motorized faders are used to
change input and output levels. An LCD panel is provided to display operational
information. A rotary encoder allows easy parameter changes. All changes to levels
and input sources are carried out by cross fading and so do not give rise to glitches.
Operation
Upon power-on the remote controller will attempt to communicate with the
last accessed target processor. It is recommended that the target processor is powered
on before the remote controller. If successful a C will be displayed to the right of the
address on the LCD and all the settings in the target will be uploaded to the remote.
The remote does not carry any memory of its own (Except the last accessed address).
In this way the remote will always follow the settings of the target processor currently
addressed. The remote can operate in one of three modes, Matrix, Mix or Dual. These
are described below: -
Matrix mode operation
This mode is selected by depressing the quad button. The remote will send a
mode change command to the target and then upload all the target’s matrix mode
settings. The current matrix selections will be shown on the LED indicators in the
matrix switches, any inversions will be indicated on the relevant switches. The faders
will be driven to a position corresponding to the levels associated with the selected
inputs. Four green LEDs to the left of the keyboard indicate that all four input sources
are active and can be adjusted by the faders. Each column of matrix switches
corresponds to an output. Selecting one switch in an output column directs the
corresponding input to that output. Each input associated with a particular output has
a unique level setting. I.e. input 1 when connected to output 1 can have a different
level setting to input 1 when connected to output 2. Depressing an invert button will
invert that input. An LED will be illuminated and a down arrow will appear beside the
level indication to show an inversion is active. For possible input sources and output
destinations see setup below. Also see the Bel 2120 or Bel 2140 manual.
