Principle of
operation
To prevent mutual interference
when operating in duplex mode, the
data transmission system use two
different frequency pairs. These are
set via the control panel.
Both devices monitor the received
signal level which can be displayed
on a bar graph indicator. If the
received level drops below a certain
level e.g. due to soiling of the optics,
a warning output signal is activated.
All work on the device (mounting,
connecting, aligning, configuration)
