FOR-22 4-WIRE INTERFACE
2-7
ADJUSTMENTS
After installation the front-panel controls should be set to accommodate the
normal range of input and output levels encountered. The following is a
discussion of the controls and indicators on the front of the interface.
"Send Level" Control
The "send level" control allows adjustment of the output level of the channel
from the matrix to the external device/system.
"Send Level" LED
The 2-color "send level" LED lights green when an audio signal is being sent to
the external device or system at a typical acceptable level. The LED lights red
when the audio output signal level is too high.
"Recv" Control
The "recv" ("receive") level controls affect the level of signals sent from external
devices or system to the matrix. The "recv" controls have a range of ± 10 dB.
Relay Active LED
The yellow "relay" LED lights whenever the relay is activated. Intermittent fast
blinking on this LED is normal.
CONFIGURATION
You configure a central matrix port to work with the FOR-22 interface by setting
parameters in the Eclipse Configuration System (ECS) programming software.
Refer to the Eclipse Configuration System Instruction Manual for more
information.
