Technical Manual Overview
The Installation Manual for Innotech Device Network Cabling is part of a series of technical manuals
designed to provide the customer with complete and comprehensive documentation supporting the
Innotech Digital Control system. It contains detailed information for the primary network and the two
sub networks.
• Network Connections
• Earth connection rules
• End Of Line Termination
• Descriptions on dierent comms hardware improvements
About this Manual
This instruction manual is intended to provide the user with complete and easy-to-follow instructions
for installation of Innotech Communication networks. In preparing these instructions, Innotech
assumed that the installer is familiar with the installation of RS485 Communication networks.
The following instructions and procedures are presented at a technical level that assumes familiarity
with networks and local electrical rules and regulations.
Because each network is designed to be configured to its own application requirements and since
each customer's application is dierent, no two sites will be the same. However, the following rules
and information will cover any possible scenarios.

Chapter 1 - Common
Requirements
Innotech Device Network Cabling Installation Instructions
1-1 Definition of RS485 or EIA-485
The term RS485 is outdated and was replaced with the latter specification called EIA-485 [TIA-485]
balanced (dierential) communication interface however the industry still uses RS485 and it is still
used in this manual.
‘Balanced’ means that two signal wires are required to produce an alternating signal pattern. i.e. if
the [+] terminal is measuring +5V then the [-] terminal is reading 0V, conversely if the [-] terminal is
measuring +5V then the [+] terminal is reading 0V.
For reliability, when interconnecting dierent equipment, 3 wires are required. Typically those are
named [+, -, 0V or S]. [+/-] and are used for data. [S] is the signal reference. Instead of having an
individual third wire for [S], the shield from the Shielded Twisted Pair (STP) cable is used.
The RS485 interface is operating in ‘half duplex’ mode. Meaning only one transmitter can be active
at the time but many receivers can listen simultaneously. A period of ‘silence’ is used to free the
interface for another transmitter to become active.
Two more terms are frequently mentioned in conjunction with RS485.
1-1.1 Termination
EOL: Will be referred to as ‘End of Line’ termination, in this manual.
A resistor (load) connected between terminals [+/-] of typically 120 Ohms.
There is one resistor connected at each end of a cable.
It is sometimes user selectable or fixed internally to the device.
1-1.2 Biasing
These are referred to as ‘Pull-up/Pull-down’ or ‘Idle-line failsafe’ resistors.
A weak current limited power supply individually connected to terminals [+ and -] to define the 485
interface to be Idle or silent when no transmitter is active, which is important to operate reliably in
‘half duplex’ mode.
The idle bias level can be checked with a voltmeter measuring between terminals [+ and -].
The reading is to be greater than +/-200mV.
NOTE
Ensure that there is no comms activity while measuring.
1-1.3 Communications speed
Faster is not always better. Speed is a trade o between cable length and cable quality, link
reliability, controller processing capability, cost and data quantities.
There is no doubt that increasing network speed makes networks more diicult to set up or fault find.
Therefore it is important to take care during installations on where, how and what cables are routed
between controllers.
The selected speeds of Innotech networks of controllers and wiring instructions in this manual are
set out to achieve the best reliability.

Innotech Device Network Cabling Installation Instructions
1-2 Definition of Earth Types
There are three types of earth referred to in this document:
• Bonded, hard or clean
• So
• Floating
These definitions are listed below in relation to the Innotech networks.
Table 1-1: Earth Types
Typ e Description
Bonded,
Hard or
Clean
So
A bonded, hard or clean earth is defined as a low impedance earth point with little
or no chance of conducted noise either already present or likely to be created when
bonded to a circuit. For Innotech’s reference we also explicitly mean there is no
potential dierence to true earth.
A so earth is where there is a path to earth via a circuit. This provides a tie to earth so
potential dierences are minimised. This path has higher impedance than a bonded
earth. This does force strong earth currents, i.e. leakage currents from large AC motors,
to remain on the proper heavy gauge earth wires, while leaving the so earth paths
unaected. So whilst having multiple earth connections we have not created any
eective earth loops.
So earth is oen used in 24 V supplied devices. The ‘tie to earth’ is in fact a ‘tie to 0 V’
because there is no dedicated earth terminal available. It is therefore expected that
the 0 V is earthed near the supply transformer.
Floating
Floating simply means that there is no path to an Earth point at all provided by the
device, not even a so earth path. A floating device has no earth.
1-3 Earth Points
It is imperative that the screen is earthed at one point only and this is defined as any point along a
network that is the best earth point along its length. Where ‘best’ earth point, is the point with least
amount of earth potential fluctuations. i.e. A controller in the basement of a high rise building is
closest to a good earth point than a controller in the plant room on top of the roof.
While there are internal jumpers on some devices to link the ‘S’ terminal internally to earth, there are
variants in hardware types and revisions, simply connect a bonded earth as shown externally. This
will suit all installations, regardless of age. If a repeater is installed each side of the repeater is to be
treated as a separate standalone network and each must have an earth connected.
NOTE
When there is more than one connection point to earth the screen becomes a conductor and no longer performs
correctly. Care should be taken to ensure only one bonded earth point is ever connected on a primary network.
Refer to Chapter 2-6 for details on use of a Repeater in a primary network.

Innotech Device Network Cabling Installation Instructions
There are a number of rules that apply to the comms connection of a primary network.
Some of these are explained in detail in Chapter 1 of this manual.
Primary network rules:
• The screen must be continuous
• Only one point earthed on the screen
• Even if a network has a number of devices with a so earth, one hard earth is still required on that
network
• The Net and Global networks should have the same length cable run and path
• If a repeater is installed, each side of that repeater is a separate network and each requires a
bonded earth connection on the screen
• Using isolated devices, devices with isolated comms cards or using an isolated MPI does not alter
any of these rules
• There are no End of Line termination (EOL) requirements on the primary network
2-1 Continuous Screen
The screen on a primary network needs to be continuous. That means it remains unbroken along its
entire length. As there is one ‘S’ terminal on a typical primary network device both the global and net
screens are to be connected to this tie terminal.
G+ S N+G- N-
GLB Comms
NET Comms
Figure 2-1: Typical Screen Connections
NOTE
When there is more than one connection point to earth the screen becomes a conductor and no longer performs
correctly. Care should be taken to ensure only one bonded earth point is ever connected on a primary network.
Refer to Chapter 2-6 for details on use of a Repeater in a primary network.

Innotech Device Network Cabling Installation Instructions
2-2 Management of other devices on the Primary Network
When other controllers such as Viewports or converters are added to the primary network they must
be installed in a manner that does not interrupt the integrity of the primary network. A lot of current
devices will have the so earth option and are fully isolated from the factory. There is no issue mixing
the current style earth connection with previous models of hardware on the primary network if the
following rules are applied.
These HMIs and converters will be referred to as so earth devices with respect to comms screen
termination.
For any so earth type device connected to a primary network there are some general rules for
connection.
• Do not break the continuity of the screen
• Use the ‘S1’ terminal for both the entering and leaving screen termination
• You must earth the system at a single bonded earth point. This is regardless of the number of so
earth points connected
• Attempt to ensure the net and global networks are the same length and follow the same path
2-2.1 HMIs and Converters
Typically all converters or HMIs will connect to the NET network and do not connect to the Global
network. This will present a few variations in how this device could be connected to the network. It is
important to ensure that the screen is kept continuous.
The below connection is wrong because it breaks the continuity of the screen creating a situation
where potential dierences in earth current between Device 1 and Device 2 can occur, therefore the
reliability of the comms connection may be compromised.
Figure 2-3: Incorrect HMI or Converter Comms Connection
In the correct example, notice that the NET comms screen is in ‘S1’ terminal only. If you were to
use the ‘S1’ and ‘S2’ terminals you would break the continuity of the NET screen. This could cause
a potential dierence between each side of the HMI or converter and possibly introduce network
reliability issues.
The HMI or converter must have the Earth terminal or the 24V neutral, connected to earth where
available. This will provide the path for the so earth.

2-2.2 Control Stations (ICS) and DynaLite Gateway (IG02)
Control Stations and DynaLite Gateways connect to the Global network and do not connect to the Net
network. This will present a few variations in how these devices could be connected to the network.
It is important to ensure that the screen is kept continuous.
This style of connection applies to all globally connected devices.
The rules of application are similar to that of the HMI or Converter connections in the prior section.
You must ensure the global and net cable lengths are the same.

Figure 2-6: Correct Station IG02 Comms Connection
In this correct example you can see that the GLB comms screen is in ‘S1’ terminal only. If you were to
use the ‘S1’ and ‘S2’ terminals you would break the continuity of the GLB screen. This could cause a
potential dierence between each side of the ICS / IG02 and possibly introduce network reliability
issues.
The ICS / IG02 must have the earth terminal or the 24V neutral, connected to earth where available.
This will provide the path for the so earth.

2-2.3 Earth Connections
The earth connection type on HMIs and converters depends on the typical application of the device.
A potential earth dierence between main installations and remote HMIs can cause problems in the
network.
An attempt must be made to eliminate the earth potential dierences between the Net comms
and Global comms network cabling. This applies to any so or floating earth device connected to a
primary network.
The list below indicates the dierent types of earth connections.
• The GENII VIEWPORT has terminal 3 for the dedicated earth connection. It is used for the so earth
path of the comms screen terminal
• The MP01 MiniPort has terminal E for the dedicated earth connection. It is used for the so earth
path of the comms screen terminal
NOTE
Where either the GENII VIEWPORT or MP01 MiniPort may have the 24V neutral earthed there is no link to the earth
terminal. Therefore a hard earth connection to the earth terminal is still required.
• The CONV E should have the 24 V supply earthed on the secondary of the transformer as best
practice. The CONV E has a floating type screen connection
• The CONV USB and the CONV 232 are isolated or floating devices and where they have a so earth
type comms connector fitted there is no path to earth available at these devices
The following indicates how a network can be practically wired to eliminate earth potential
dierences and problems that may occur between the Net and Global networks.
1. When the HMI or converter is mounted at the end of a run, the Global can finish at the last
controller. It is suicient to run NET only from the last controller to the HMI or converter.
Figure 2-8: End of Run Mounted HMIs or Converters
Chapter 2 – Primary Networks
Page 21

Innotech Device Network Cabling Installation Instructions
2. In the wrong example below, the cable run for the NET comms is significantly longer than that
of the Global comms. This can cause an earth potential dierence between the net and global
screen resistances and therefore unequal current flows which can cause network problems.
Figure 2-9: Remote Mounted HMIs or Converters
To rectify the above incorrect wiring situation you must use one of the following options:
• Branch o earth screens at the single comms earth point where the Net cable is routed through the
HMI without the Global cable. This is the Hard Earth.
• Keep the Net and Global network cables the same length and following the same path

comms, an d to and

Figure 2-10: Options to eliminate earth potential dierences between networks
NOTE
Generally in all installations care must be taken when selecting the best earth point. Good earth points are usually
close to the earth stake and away from heavy power equipment. Heavy power equipment causes earth currents
and therefore the earth point is subject to potential dierences in current interference, and as such is usually not a
good choice.

2-3 BACnet Gateway (IG03)
The BACnet Gateway is dierent to any other Innotech device in that it acts as a Network Master. It
has a PC and Net Comms connection. As there is only a single shield terminal the shield for each
network should be connected to this terminal. All other Innotech wiring guidelines should be
followed.
The BACnet network should always be totally separated from the Innotech network and any BACnet
specific wiring rules should be adhered to.

2-4 Older Controllers
There are some earlier devices, version V3, V3.1 and V3.2 Genesis and MPC controllers that do have
jumpers available to internally connect the ‘S’ terminal to either the 0 V terminal or a separate Earth
terminal.
NOTE
These jumpers have not been fitted at point of manufacture to suit the style of earth connection recommended in
this document.
2-5 Isolated Devices
Regardless of the type of isolation used in either the current model devices (all now standard with
fully isolated so earth) or older series controllers (plug-in optional isolation card), there is no
eect on the primary network earth requirements. The isolation is not on the primary network, but
between the primary network and the power supply of only that respective controller. All network
rules apply as stated.

2-6 Dual Channel Repeaters
NOTE
For information regarding the conditions when a repeater should be added to the Primary Network please refer to
Chapter 4 of this manual.
When a repeater is added to a network it eectively creates two separate networks.
This means users must apply all the rules to each side of the repeater as if they were actually two
completely separate networks. All primary network rules apply without variation.
All repeaters do have So Earth features. They do not negate the need for a hard earth on either
side of the repeater network sections. It is not recommended to earth both ports (1 & 2) right at the
repeater as this would defeat some of the advantages of the port isolation. Port 2 (remote port)
should always be earthed on the remote side.
CAUTION
Hazardous Voltage between Earth-Connections
When the Digital Controllers are supplied and earthed from two dierent switchboards, a hazardous situation
can be created. One earth connection is at the local switchboard and the second earth connection is by way of the
screen of the comms cable. In the event of a fault, there could be full supply voltage dierence between the two
earth connections. Always measure the voltage between Port 1 & 2 screens before handling. Use appropriate safety
precautions.
2-6.1 Older Repeaters
The GENII RPTR is the earlier version repeater, easily identified by the fact that it is housed in a square
surface mount enclosure. On these older repeaters Port 1 and Port 2 are isolated from each other;
however Port 1 is internally connected to the main electronic circuits. Due to this; Port 2 is better
isolated and has a higher level of tolerance with respect to comms protection.
It is best to ensure that if there is a long run and the converter is in building A and running to building
B; Port 2 is used to feed Building B. As shown in Figure 9.
The power terminal earth connection is a safety earth because the GENII RPTR is supplied with 240
VAC. This terminal is NOT connected to the So Earth terminal located between Comm Ports 1 & 2.
NOTE
The earth on the RPTR is connected to the so earth terminal as a requirement.

2-6.2 New Repeaters
New repeaters are identified by the fact that they are mounted in a DIN rail mount enclosure. Neither
have a separate earth terminal as it is a 24 V AC powered device, however the 24 V supply must be
earthed on the 0V side for safety and to make use of the So Earth feature.
• The IR12 is the current dual channel and dual baud rate repeater
• The IR11 is the current single channel dual baud rate repeater
• The IR12 and IR11 are fully isolated and both Port 1 and Port 2 oer the same level of protection.
That means that both Ports 1 & 2 can be used for the remote site connection.
NOTE
The earth on the IR12 must be connected to the so earth terminal.

2-7 End of Line Termination (EOL)
Due to specific design parameters relating to the bias of the network and network configurations, the
Primary network has currently no need for End of Line Terminations (EOL).

The only device on a REM network without an earth terminal is the IR11 repeater. It must have the 0 V
of its power supply earthed.
REM Device REM Device REM Device
Figure 3-1: REM Network
3-1.1 So Earth
All REM devices have a so earth and as such the Earth must be connected to the terminal ‘E’. This
provides the required path to earth. It is not suicient to have the 0V earthed on the 24V powered
devices as these are separated.
3-1.2 End of Line Termination (EOL)
All REM’s have EOL jumpers and these must be fitted correctly. See the figures below.
There are many variations to network layouts the following four examples provide a guide to correct
jumper application.

3-2.1 VAVMax (VM01) and MicroMAX (UM01)
The VAVMax and MicroMAX have a 5 way connector where the terminals are made up of P+ P- C+ CSHLD. This is due to the fact that the Sub System Network Commissioning Tool (CT01) is powered by
the P+ and P- terminals. These terminals have dierent pin spacing to the primary network terminals
and while they look similar, they are not, and can’t be interchanged.
3-2.2 MiniMAX (MM02)
These MiniMAX controllers have the REM style of comms connector.
When used in conjunction with VAVMax or MicroMAX controllers, care should be taken to ensure only
the S1 terminal is used to maintain the continuity of the screen.

4-1 Network Specifications
The network type and baud rate determine the maximum recommended cable specifications. For
cable runs longer than the recommended lengths an Innotech Repeater IR11 or IR12 should be used.
Repeaters may also be required if the number of devices connected to a network segment exceeds
the maximum allowable number of devices for the specific network.

4-2 Cable Specifications
Innotech recommends the use of cables specifically designed for RS485 networks. There are many
cables on the market that meet the specifications for RS485 networks.
Best reliability is achieved through a cable consisting of 2 individually shielded twisted pairs of low
capacitance. Such cables also provide excellent mechanical strength and lowest electrical resistance,
which is beneficial for maximum length cable runs.
Some CAT6 cable types may also be suitable in certain applications. Care should be taken when using
CAT6 for Primary Networks as they frequently omit shielding. CAT6 cables should be shielded in order
to provide reliable communications.
Edition 3.0 dated 05.12.2013

Innotech Device Network Cabling Installation Instructions
4-2.1 Primary Network
Any cable that meets or exceeds all the stated specifications is suitable for use.
Primary Network Minimum Requirements:
• 2 twisted pairs
• Minimum conductor cross section AWG24 (0.205mm²)
• Stranded core type is recommended (7 strands of 0.193mm)
• Conductor resistance 80 Ohms / km or less
• Overall Foil screened cable with a wire drain
• Less than 50pf capacitance per metre between conductors
• Less than 80pf capacitance per metre between conductor and screen
• Impedance 100 – 120 Ohms
• Sheath thickness 0.8mm 240V rated
• Equivalent to the Belden Part #8102
NOTE
CAT6 STP (Shielded Twisted Pairs), where each pair is individually shielded, are suited for use with multiple
RS485 communications channels such as the Innotech Primary Comms network. Shielding is required because of
increased pair to pair capacitance, which is the primary culprit for Global/Net channel cross talk.
4-2.2 Sub Networks
CAT6 FTP (Foil Screened Twisted Pair) cable is suitable for single RS485 communications channel
networks.
Any cable that meets all the stated specifications is suitable for use.
Sub System Network Minimum Requirements:
• 1 twisted pair
• Minimum conductor cross section AWG24 (0.205mm²)
• Stranded core type is recommended (7 strands of 0.193mm)
• Conductor resistance 80 Ohms / km or less
• Overall Foil screened cable with a wire drain
• Less than 50pf capacitance per metre between conductors
• Less than 80pf capacitance per metre between conductor and screen
