Table 2-1. Connector Pin Functions
Pin Function Description
1 External
Speaker- Speaker - and S (Pin 16) are used to connect an
external speaker. The audio PA is a bridge amplifier with a
minimum load resistance of 3.2
Ω
. The internal speaker
can be disabled by removing the control head. Disconnect
the internal speaker and assemble the control head back
to the radio.
2 External Mic
Audio External or Emergency Mic depends on dealer
programming. This microphone signal is independent of
the microphone signal on the microphone connector. The
nominal input level is 80mV for 60% deviation. The DC
impedance is 660
Ω
and the AC impedance is 560
Ω
.
3 Digital In 1 This is a digital input only and the primary use for this pin
is external PTT. This pin must be used if fast DATA PTT is
required.
(See Note 1).
4 Digital Out 2 This is a digital output only and the primary use for this pin
is as an external alarm output (See Note 3).
5 Flat_TX_Audio
(NPD Data Out) This input is intended for injecting signals into the transmit
path that should not be filtered; for example, the analog
output of a modem.
The nominal input level is 150mVrms for 60% deviation.
The impedance is greater than 25k
Ω
.
6 Digital In 3 This is a digital input only. Function depends on dealer
programming.
(See Note 4).
7 Ground Used as ground for both analog and digital signals
8 Digital In/Out 4 This is a digital input/output depending on dealer
programming.
(See Notes 1, 2).
9 Digital In 5 with
Wakeup
Emergency This is a digital input only. Emergency can be enabled via
the CPS. To activate, this line must be connected to
ground; this will turn on the radio. The CPS details which
functions may be assigned to this pin by the codeplug.
10 Ignition Detect Connecting this line to the ignition line of the vehicle will
automatically turn the radio on when the ignition of the
vehicle is turned on.
11 Receiver Audio There are two possible outputs: (1) Discriminator Audio;
and (2) Continuous filtered RX audio. The nominal output
level for Discriminator Audio is
330m Vrms at 60% deviation and for Filtered Audio 600m
Vrms at 60% deviation at 1kHz. Function depends on
dealer programming.
12 Digital In/Out 7 This digital input/output function depends on dealer
programming.
13 Switched
Battery Voltage This voltage is available when the radio is switched on.
The maximum current is 1A.
14 Digital In/Out 8 This is a digital input/output depending on dealer
programming.
(See Notes 1, 2).
