Controller Termination
The 400DA is packed with control options:
USB: Intended for initial installation
Programming or firmware update.
Not intended for permanent connection
to a PC or other control system.
ETHERNET: 100BaseT connection to a
Home network router or switch.
RS232 Serial: Electrically isolated
Prevents hum in analog input circuits.
CONTROLLERS: Conveys +12VDC,
IR and Data between the 400DA and
Axium keypad controllers, connected
using CAT5 cables.
BUS RUN: (Legacy) Port conveys
+12VDC, IR & Data to remotely connected
IR controllers.
AMPON: +12VDC 100mA trigger
output when a Zone is ON.
PRESETS: P1 and P2 Inputs are active low.
Connect C (common) and either P1 or P2
across an illuminated door bell switch.
The illuminated doorbell switch must have an
External 12V – 24V AC/DC supply and
current limiting resistor connected.
If a dry contact is to be used for PRESET
Activation, it must be normally closed or a FIG 3
Push to break contact.
The BUS RUN 0V and +12V can be
connected as shown in FIG 3
EXPANSION BUS: Simple Patch cable
interconnection for Axium amplifiers that
conveys control and data between
amplifiers in a stack.
The cable length must be < 0.5m.
Interconnection to older Axium amplifier
models is possible only for the Control
functions.
A special cable must be made. See FIG 4.
In older Axium amplifier models Analog
audio was conveyed through a 34 way IDC
cable. This is no longer supported, and
connections must be done using RCA
splitters in the analog audio inputs.
