2 Connections and Status Indicators
2.1 RVI-600 TX and RX Connections
Refer to Figure 2-1 for Connection descriptions.
TX1 is a default transmitter port. Voted audio is routed out of this port along with PTT or tone keying depending on
how the transmitter port is configured.
RX1 and RX/TX 2 through RX/TX 6 are receiver ports, or ports that vote. By default, all six are configured to vote on
loss of status tone (2175 Hz at -13 dB). Options for other status tones as well as to vote on COR detect are also
available with additional advanced setup which can be found in section 3.
RX 1 is a receiver port only
but RX/TX 2 through RX/TX 6 are configured as combination transmitter and receiver
ports providing a multicast voting capability as needed.
The console port provides an input to any console as well as an output for voted audio. When the console port has
inbound audio it will be routed to the default transmitter (TX1).
If tone keying (default), the RVI-600 turns off its keying when console audio comes in and allows the keying
tone sequences from the console to key the transmitter. If relay keying, the transmitter port will provide the
PTT for keying of the radio when the console is active.
By default, the console has transmit priority for TX1 over any voted audio path. Console priority allows the dispatcher
to take priority over the transmitter from a port previously voted and using the transmitter
2.2 TX and RX Pin-Outs
The pin assignments for RX, TX, and Console ports (RJ45) is outline below.
Pin 1
RX A
Input audio from Customer Equipment.
Pin 2
RX B
Input audio from Customer Equipment.
Note 1
Pin 3
PTT or M-Lead Out
Output switch closure to customer equipment.
Pin 4
TX A
Output audio to Customer Equipment.
Pin 5
TX B
Output audio to Customer Equipment.
Note 2
Pin 6
PTT or M-Lead Ground Return
PTT ground return to customer equipment.
Note 3
Pin 7
COR or E-Lead In
Active low input from customer equipment.
Note 4
Pin 8
COR or E-Lead Ground
Ground connection to customer equipment.
Note 1
: For unbalanced radio connections, this pin typically connects to a ground pin in the radio. Otherwise pins 1 &
2 are a balanced pair and polarity need not be observed.
Note 2
: For unbalanced radio connections, this pin typically connects to a ground pin in the radio. Otherwise pins 4 &
5 are a balanced pair and polarity need not be observed.
Note 3
: PTT is by default set for Active Closed (normally open) but can be changed to Active Open (normally closed).
Note 4
: COR input by default is set for Active Low, but can be changed to Active High.
