(3) Explanation of Example System
In the example system shown in Figure 4-16 two C-5000's part number 31300-1202-1220
are sharing the control of two RT-5000's. Note the following key elements of the wiring:
a) The wires between P501 of both C-5000's are built in a "Y" configuration and
run to RT-5000 #1.
b) The write between P502 of both C-5000's are built in a "Y" configuration and
run to RT-5000 #2.
c) Two "Take_Control" switches (one for each transceiver) allow the operator to
switch the control of a radio between control heads.
d) The primary headset/microphone audio's on P500 of each C-5000 are
paralleled and connected to the FM1 position on the audio panel. The
secondary headset/microphone audio's on P500 of each C-5000 are paralleled
and connected to FM2 position on the audio panel.
If an operator wants to control RT-5000 #1 with C-5000 #1, they put the Take_Control
switch for radio #1 in the position that grounds pin 17 of P501 on C-5000 #2. At this point,
C-5000 #2 gives up control of RT-5000 #1 and displays "NO CONTROL" on the top line
of its display. C-5000 #1 will now show the status of RT-5000 #1 on the top line of its
display To transmit on radio #1, the operator tunes the audio panel to FM1 and
pushes the PTT switch.
If an operator wants to control RT-5000 #1 with C-5000 #2, they put the Take_Control
switch for radio #1 in the position that grounds pin 17 of P501 on C-5000 #1. At this point,
C-5000 #1 gives up control of RT-5000 #1 and displays "NO CONTROL" on the top line
of its display. C-5000 #2 will now show the status of RT-5000 #1 on the top line of its
display To transmit on radio #1, the operator tunes the audio panel to FMI and
pushes the PTT switch.
If an operator wants to control RT-5000 #2 with C-5000 #1, they put the Take_Control
switch for radio #2 in the position that grounds pin 17 of P501 on C-5000 #2. At this point,
C-5000 #2 gives up control of RT-5000 #2 and displays "NO CONTROL" on the bottom
line of its display. C-5000 #1 will now show the status of RT-5000 #2 on the bottom line of
its display To transmit on radio #2, the operator tunes the audio panel to FM2 and
pushes the PTT switch.
If an operator wants to control RT-5000 #2 with C-5000 #2, they put the Take_Control
switch for radio #2 in the position that grounds pin 17 of P501 on C-5000 #1. At this point,
C-5000 #1 gives up control of RT-5000 #2 and displays "NO CONTROL" on the bottom
line of its display. C-5000 #2 will now show the status of RT-5000 #2 on the bottom line of
its display To transmit on radio #2, the operator tunes the audio panel to FM2 and
pushes the PTT switch.
