DESCRIPTION
The RSA-U5 is used to
connect voice logging recorders to two-way radios that do not have an output for
recorders, such as a mobile radio that is used as a base station. Radios with
wired connections for remote control (tone, DC, or local) can usually be
directly connected to most recorders and do not require the RSA-U5.
Since connections must be made inside of the radio, it
should only be installed by a radio service technician that is qualified to
service the radio.
FEATURES
► Adjustable gain amplifiers allow you to
independently match transmit and receive audio levels for optimum
recordings.
► Switch selectable mixing of
receive and transmit audio at all times or transmit audio that is only present
with active PTT.
► Optically isolated DC
sensing mutes the transmitter microphone audio when the radio is not
transmitting (push-to-talk is not active).
►
Includes 110vAC power supply, eighteen inch input cables for radio connections
and an RJ-11 modular audio output jack.
► Red LED to
indicate PTT (Push To Talk) activity. Green Power LED.

NOTES
►
If the receive audio source is the radio speaker, the recorded audio will
increase and decrease with the volume control on the radio. To prevent this, it
is recommended that the receive audio be sourced from the radios squelched
discriminator audio so that the position of the volume control on the radio will
not have any control over the recorded audio.
►
If your connection to the radio’s transmit audio is at a point where microphone
audio is only present when transmitting, you can place the Transmit Audio Switch
in the RX+TX position and leave the two wire TX-SENSING cable disconnected. In
this mode, the RSA-U5 will mix transmit audio with receive audio at all times.
► If your connection to transmit audio is at a
point where microphone audio is present when the radio is not transmitting and
the Transmit Audio Switch is in the RX+TX position, you will record room audio
when not transmitting. In this case, the mute control cable should be connected
to a place in the radio that provides between 5vDC and 16vDC when transmitting
and the switch placed in the TX-PTT position. This connection powers an
optically isolated sensing circuit so that the output will only have microphone
audio when the radio is transmitting (PTT is active).
► The RSA-U5 has two screwdriver adjustable audio output adjustments.
One adjusts the volume of the receive audio that is fed to its output jack, the
other adjusts the volume of transmit audio fed to the output. Adjust these
controls as needed to match levels and for the best recorded audio. Adjust
clockwise to decrease, counter-clockwise to increase. Do not force these
controls.
► The modular phone jack (RJ-11) on
the RSA-U5 provides line level RX+TX audio for your recorder (suitable cables
are supplied with Omnicron recorders). Only the center two wires in this jack
are used. WARNING: Connecting this jack to an active phone line could damage
the adapter and will void its warranty.

INSTALLATION
The RSA-U5 is supplied with cables and connectors wired
to meet most standard applications. It can also be customized to meet unusual
requirements. Since connections to most radios must be made inside of the radio,
only a radio technician familiar with the radio should perform the
installation.
1. The short 3 wire gray cable
connects to the 2-way radio audio.
a) Connect the BLACK lead to radio common (chassis
ground).
b) Connect the
GREEN lead to receive audio (0.1 to 1.5 vAC).
c) Connect the RED lead to transmit audio (0.05 to
1vAC).
2. The short two wire gray cable
connects to two-way radio transmitter power (DC). If microphone audio is only
active when transmitting, this cable does not need to be connected. Place the
Transmit Audio Switch in the RX+TX position.
With the Transmit Audio Switch in the TX-PTT position, these wires feed
an optically isolated sensing circuit that will mute the transmit audio whenever
they do not have between 5vDC (1 ma) and 16vDC (4 ma) present across them.
Connect the BLACK lead to negative (-) side and the RED lead to positive (+)
side of switched transmitter power. This voltage also powers a green LED.
3. The RJ-11 telephone style jack on the
RSA-U5 is used to connect the audio output from the RSA-U5 to your recorder’s
audio input. Receive and transmit audio are mixed on the center two pins of this
RJ-11 jack. Use the cable supplied with your recorder or other suitable wiring
to connect from this jack to your recorder.
4.
Plug the supplied AC adapter into the Power (5 to12vDC) jack and AC power. A red
LED on the RSA-U5 lights when power is ON.
5.
Check that the recorder is recording both transmit and receive audio properly.
If needed, increase or decrease audio levels using the small screwdriver
adjustable controls on the RSA-U5. One adjusts the level of receive audio, the
other adjusts transmit audio level (turn clockwise to decrease, counterclockwise
to increase).
The RSA-U5 is supplied with cables and connectors wired to
meet most standard applications. It can also be customized to meet unusual requirements.

IN CASE
OF DIFFICULTY
If the unit fails
to work properly, check all connections, audio, and DC voltage levels. Test your
recorder to see that it is operating properly. Assistance is available from your
place of purchase, or directly from Omnicron Electronics.
