1)
LED INDICATION: SIGNAL SQUELCH (green Led).
Green Led is on when a signal is correctly received.
2)
LED INDICATION: PILOT-TONE SQUELCH (yellow Led).
Yellow Led is on when the correct sub-audio pilot-tone is present on the received signal.
3)
LED INDICATION: ACTIVE RECEIVER (red Led).
Red Led is on when the receiver is feeding the audio output line.
(Red Led is present only on the CRS 50-DY model, pre-set for remote diversity receiving).
4)
CHANNEL SWITCH (0 ÷ F).
5)
LED INDICATION: APPARATUS ON (red LED).
6)
ON / OFF SWITCH (Power).
7)
CONNECTOR: ANTENNA (type N female).
8)
CONNECTOR: AUDIO SIGNAL OUTPUT (type XLR3-M).
The audio signal output is transformer-balanced and floating.
• pin 1 = ground
• pin 2 = output AF-a
• pin 3 = output AF-b.
9)
CONNECTOR: DIVERSITY-CONTROL INPUT/OUTPUT LINE (D15-F type connector - optional).
The diversity control line is opto-isolated and floating. • pin 4 = ground; • pin 5 = DY-I/O-a; • pin 9 = DY-I/O-b.
The working area of the communication system is increased though the use of two or more CSR50-DY receivers
(with built-in DYB50 diversity board). These receivers can be installed in different locations and connected together
to operate in diversity mode. In this case the diversity control line of each receiver has to be connected in parallel
with the one of all receivers, keeping the same phase. Obviously, the frequency of all receivers working in diversity
mode must be the same. If the diversity control line is kept isolated, the CSR50-DY receiver module can operate
normally in not-diversity mode.
10) CONNECTOR: DC POWER INPUT (10.5 ÷ 16 Vdc)
