Easy operation.
There are no front panel controls.
Both coax input and fiber input has Automatic Gain Control, AGC.
If the input signal is outside the AGC’s limits, the signal is to low or to high, the
signal for that input is blocked.
If both inputs have a signal within AGC limits, the signal from the fiber input is
used.
LED indicators.
At the output panel, there are 2 LED’s – INPUT STATUS .
They are marked – FIBER- and – COAX - .
They can both individually take the state of red or green.
Green indicates that the input has detected a signal within the AGC limits –
Signal good.
Red indicates that the input signal is outside the AGC-limits, as when there is
no signal attached. Red also indicates that the signal for this input is blocked.
If both LED’s are green, the coax input signal is internally blocked and the fiber
input signal is switched to the outputs, both fiber and coax outputs.
If both LED’s are turned off , there is no power supplied to the DA-36.
Grounding
As ground loops are the cause of most problems in coaxial networks, all coaxial
ports, both input and outputs are individually configurable to be galvanic
isolated or connected to case/chassis ground.
The case also has a chassis ground screw.
Remember that ground connections shall be low impedance also at high
frequencies, a bad ground connection can introduce unwanted ground loops, and
degradation of signal quality.
Short distances and large conductor areas are essential.
