PAGE 7 IN400 INSTALLATION AND OPERATION MANUAL
INSTALLATION
POWER CONNECTION
Ensure the mains voltage supply matches the rear of the IN400 (+/- 10%)
Ensure that all system grounds (earth) are connected to a common point. Avoid
powering equipment within a system from multiple power sources that may be
separated by large distances. This will eliminate ground loops that are heard as
50/60Hz humming or buzzing in speakers and seen as moving or stationary bars
on video equipment.
INPUT CONNECTIONS
Audio
All the inputs are unbalanced RCA sockets. Unbalanced RCA wiring should be
keep as short as possible. Typically less than 3m.
Video
Video inputs are on either unbalanced RCA sockets (composite) or 15 pin high
density female connectors D-connectors (VGA). The maximum cable length for
composite video is typically less than 3m for shielded wire and 10m for coaxial
before signal degradation. This will depend on the cable quality.
OUTPUT CONNECTIONS
Audio
The line level outputs are unbalanced RCA sockets. Unbalanced RCA wiring should
be keep as short as possible. Typically less than 3m.
The amplifi er outputs are 5.08mm pluggable connectors. Use the following table
for selecting a suitable guage wire for the cable you are running over a particular
distance. The table is for a 1dB drop in level which is generally considered
acceptable.
OUTPUT CONNECTIONS (cont.)
Video
Video outputs are on either unbalanced RCA sockets (composite) or 15 pin high
density female connectors D-connectors (VGA). The maximum cable length for
composite video is typically less than 3m for shielded wire and 10m for coaxial
before signal degradation. This will depend on the cable quality.
There are two composite outputs for running to 2 different monitors without the
need for an external distribution amplifi er.

Only pins 1,2,3,5,6,7,8,10,13,14 are used in the IN400.
RS485 CONNECTIONS
The RS485 data port is on a 5.08mm pluggable connectors. Twisted pair cabling
should be used When connecting RS485 devices, such as CAT3, CAT5, CAT5e
or CAT6 UTP cabling. RS485 data networks should be wired in a ‘daisy chain’
confi guration with a maximum of 32 devices in the chain. The IN400 is not
terminated so may be inserted anywhere in the data network. If the IN400 is
being used at the end of a chain, a 120ohm (characteristic impedance of UTP)
terminating resistor should be connected between the + and - connections.
The maximum length of the chain is 500m.
All installation work should be done with the power disconnected. The following inforamtion will help with installation. After installation is complete power up all the
sources before turning on the IN400.
Do not connect a total impedance of less than 4ohm per channel.
