1.0 Introduction
The DNA (Distributed Network Advantage) system is a collection of components that are
interconnected to provide a versatile DMX512 distributed network. The ISOseries of
products are part of the DNA system and consist of the following devices:
Isopower – A 2RU rackmounted or wall mounted power source that supplies +24VDC power
to the ISOPORT and ISONODE network products. The rackmount unit can power upto 32
ISOPORT/ISONODE modules where the wall mount unit will power upto 12
ISOPORT/ISONODE modules. The rackmount unit has integrated front panel indicators that
display operational status.

ISPW
ISOPORT – A wall mounted DMX512 data outlet that is electrically isolated and buffered, with
integrated Power and DMX data indicators. The ISOPORT is available with one, two or three
XLR 5 pin output ports where each output port can drive upto 32 DMX512 devices. Input to
output relationships and end of line termination can also be configured during installation.
The ISOPORT is powered from a 24VDC nominal power supply
Series 1 Series 2
.
Series 3
ISONODE – A wall mounted DMX512 data inlet that is electrically isolated and buffered, with
integrated Power, upstream data and input data indicators. The ISONODE has a XLR 5 pin
input connector that senses when a transmitting device has been connected and disconnects
the upstream DMX512 data, allowing the transmitting source to control all devices connected
downstream. If the transmitting source is removed or simply stops sending data, the
ISONODE will automatically reconnect the upstream data to all devices downstream and
restore network communication. The ISONODE is powered from a 24VDC nominal
power
supply.

2.0 Installation
2.1 Isopower Rack mount
The ISOPOWER ISPR is designed for 19” rack installation. All connections are made at the
back of the chassis. The mains power supply is connected to the IEC input connector. Two
24VDC outputs are provided on 4mm² screw terminals. Output 1 and output 2 are internally
hardwired together which allows multiple ISOPOWERs to be connected together for larger
installations where load sharing and system redundancy is required.
ISPR connections at rear of chassis
2.2 Isopower Wall mount
The ISOPOWER ISPW can be installed onto any flat horizontal or vertical surface. Four
mounting holes are located in each corner of the chassis. A protective cover at one end
details the connector configuration for the screw terminals found underneath the cover.

2.3 ISOPORT module
Each ISOPORT module is supplied inside a metal installation housing that contains internal
electronics which can be configured to suit individual installation requirements. The picture
below shows a disassembled ISOPORT series 1.

ISOPORT installation procedure.
1. Remove the two screws located on the front panel.
2. Separate the front panel and associated electronics from the installation housing (as
shown above).
3. Locate the installation housing in the desired location and secure it using the four mounting
holes located at the back of the housing. Four conduit ducting holes are provided in the
installation housing.
4. Configure the ISOPORT input to output relationships with jumper LK1 as shown in table 1
on page 5.
5. Configure the ISOPORT input terminations if required. Refer to figure 1 on page 5.
6. Connect the DMX512 data and power input wiring to the screw terminal wiring strip as
detailed in table 2 on page 6.
7. Replace the front panel electronics into the metal housing and secure with the two screws.

Table 1 - ISOPORT Configuration options (ISOPORT series 2 and 3 only)
The ISOPORT allows various input to output relationships to be configured. These options are
configured by moving jumper LK1 on the isolation module to the desired position as shown in
the diagram below.

The ISOPORT has integrated input termination resistors that can be used when the ISOPORT
is at the end of the DMX512 network and requires end of line termination. Each DMX512
input can be terminated by installing a jumper across the terminals shown below.

3.0 Cable Selection
The performance of any DMX network is directly related to the quality of cable chosen to
convey the DMX information. DMX512 has a moderate data transmission rate of 250 Kbits/s,
and therefore requires selection of a cable that does not significantly distort the signal or give
rise to signal reflections.
Typical characteristics for a good DMX network cable include;
• Twisted pair with Nominal impedance of 100-120 ohms.
• low capacitance.
• Fully encased with braid and foil shielding.
• Conforms to EIA 485 requirements.
When using a single cable to carry +24VDC power and DMX data, it is important to select a
cable that has been specifically designed for this purpose. DMX data conductors should be
internally shielded from the power conductors and the power conductors (+24V and Ground
return) in the cable must also be suitably sized to carry the current from the ISOPOWER/s to
all connected DMX devices.
Cables used with audio systems are not suitable for DMX512 networks as they typically have
higher capacitance, incorrect characteristic impedance and minimal shielding. At DMX512
data rates this can cause bit time distortion and signal reflections/overshoot.
