GENERAL DESCRIPTION
The ACU is a low power, 7-channel, FM stereo transmitter, operating in the FM band (88.1-
107.7MHz). The unit has 7 transmitter “cards” integrated into a single 19-inch chassis for rack
mounting. It has two 88.1-107.7MHz output ports for two separate antenna systems. The
transmitters can individually operate in either stereo or mono mode. Each transmitter card can
be set to a specific operating frequency using the two 10-position rotary switches on each card.
The ACU has an internal regulator and power supply to provide 48VDC at 0.5 Amps to external
equipment. The unit is powered by the 37.5-volt supply from the rail transit vehicle.
The product is to be professionally installed and used in mass transit rail vehicles.
FCC Notice
FCC ID: QY4-580230
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
The user is cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment.

FRONT PANEL FEATURES (refer to drawing 580320-PINOUTS)
Stereo/Mono Switch
Set to appropriate setting
Modulation LED’s
LED’s should usually be in the green, with occasional flashes of RED. No LED’s lighted
indicates no audio input.
SW2(LSB)/SW1 (MSB)
Set to appropriate channel. Reference the Frequency Allocation Chart.
Power LED
LED is lighted when power is applied. No light indicates either there is no power to the
ACU, or the re-settable fuse has been tripped. If the PTC re-settable fuse is tripped, it
will reset itself when the problem is resolved and the re-settable fuse cools.
ANT OUT A
Connect to “A” car antenna system.
ANT OUT B
Connect to “B” car antenna system. Power to this port is attenuated by 4 dB vs the “A”
antenna connection port to compensate for cable losses in the longer “A” car antenna
cabling.
J1 POWER IN
Connects to 37.5-volt supply.
J2 ETHERNET/SU
Connect to Ethernet port of the subscriber unit. This is a pass through connection from
J6. Internally, the ACU supplies power to the SU from this port via pins 6 through 9.
See drawing 460320.
J3 ISO IN
Connects internally to pins 11 and 14 on J7.
J4 MONO CH1, 2, 3
Balanced Audio Inputs for mono channels.
J5 STEREO CH 5, 6, 7
Balanced Audio Inputs for stereo channels.
J6 ETHERNET/VMC
Connect to Ethernet port on VMC. Passes signal directly through to J2.
J7 ST CH4/ISO OUT
Audio Input for Ch 4

ANTENNA INSTALLATION
The antenna system and ACU, which are exclusively installed in mass transit rail cars,
must be professionally installed in accordance with these instructions.
The ACU is to be installed in the utility cabinet of the “B” rail car of a “married pair” rail car
pair. See the Antenna Connection drawing 550320-ANT.
The ACU connects to the antenna system as shown in 550230-ANT.
The Leaky Feeder Antenna’s are made in accordance with drawing RC-WI-002 by terminating
one end in a 50-ohm resistor and connecting the other end to an N male connector.
The components required for the Antenna System assembly are as follows:

The “A” output port of the ACU connects to the “A” rail car antenna system, which is furthest
from the ACU. This port has 4-dB more output power than the “B” ACU port to compensate for
the additional line losses to the “A” rail car.
The B port of the ACU is connected to the “B” rail car antenna system, which is the rail car in
which the ACU is installed.
The antennas are installed at ceiling level. They are spaced 40 feet apart, 17.5 feet from each
end of the rail car.
Specific assembly and routing installation information for cables, antenna and other components
of the audio/video system can be found in the manual, Interior Wire Harness Pre-Fabrication
Instructions, RC-WI-002.
