Description
PMKN4133. P4 is the 12/24 V positive DC sup-
ply input and P5 is Ground. This supply is for
the Audio Power Amplifier and is required to
connect a Loudspeaker to the RECH. This is
the only Power connection that allows 12 V or
24 V operation, all other Power supplies must
be 12 V.
3 Speaker Wires The connections correspond to P6 detailed in
Remote Ethernet Control Head Y-Cable (Ac-
cessories Expansion Cable) on page 117 and
correspond to the Loudspeaker output of the
RECH. The Audio Amplifier that supplies this
output requires an independent DC Supply.
Refer to Number 2. The use of connector
kit PMLN6487_ allows a plug-and-play installa-
tion of the associated Loudspeakers such as
RSN4002_.
4 Free-end Wires When used during installation, heat-shrink
wrap unused wires to prevent shorting. These
connections correspond to P3, as detailed in
Remote Ethernet Control Head Y-Cable (Ac-
cessories Expansion Cable) on page 117.
These connections provide multiple functions
including Hands Free Microphone (HF1 and
HF2). These two inputs are individually
screened and include a common drain-Ground,
PTT1 and PTT2, Power On, Rear Audio, and
the available GPIO lines. The use of the
IIMPRES Visor Microphone RMN5054_, also
requires the One Wire bus connection provided
on this cable.
5 Rear GCAI Connector The connections correspond to P2 detailed in
Remote Ethernet Control Head Y-Cable (Ac-
cessories Expansion Cable) on page 117 and
this connector is the 10 -Pin Rear GCAI Acces-
sory connector that enables compatible Acces-
sories such as the RMN5107_ Fist Microphone
to be connected to the rear of the Control
Head.
