Innotech Device Network Cabling INSTALLATION INSTRUCTIONS 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Innotech Device Network Cabling Installation Instructions 1-1 Definition of RS485 or EIA-485 The term RS485 is outdated and was replaced with the latter specification called EIA-485 [TIA-485] balanced (differential) communication interface however the industry still uses RS485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.
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 • Soft • Floating These definitions are listed below in relation to the Innotech networks.

Innotech Device Network Cabling INSTALLATION INSTRUCTIONS Chapter 2 - Primary Networks
Innotech Device Network Cabling Installation Instructions Primary Network Devices There are twenty-three devices that connect directly to the primary Innotech 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.
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 soft earth option and are fully isolated from the factory.
Innotech Device Network Cabling Installation Instructions 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.
Innotech Device Network Cabling Installation Instructions 2-2.3 Earth Connections The earth connection type on HMIs and converters depends on the typical application of the device. A potential earth difference between main installations and remote HMIs can cause problems in the network. An attempt must be made to eliminate the earth potential differences between the Net comms and Global comms network cabling. This applies to any soft or floating earth device connected to a primary network.
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 difference between the net and global screen resistances and therefore unequal current flows which can cause network problems.
Innotech Device Network Cabling Installation Instructions 2-3 BACnet Gateway (IG03) The BACnet Gateway is different 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.
Innotech Device Network Cabling Installation Instructions 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 effectively 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.
Innotech Device Network Cabling Installation Instructions 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 Soft Earth feature.

Innotech Device Network Cabling INSTALLATION INSTRUCTIONS Chapter 3 Sub Network Devices
Innotech Device Network Cabling Installation Instructions Sub Network Devices The Innotech Sub Networks are both two wire networks. These comprise of the REM network and the Sub System Network. The REM network is a Remote Expansion Module Network. Providing remote I/O expansion devices controlled via a Genesis controller. This network is a 38.4K baud network. The Sub System Network is a network of small point devices such as VAVMax, MiniMAX and MIcroMAX. This network is a 115K baud network.

Innotech Device Network Cabling Installation Instructions 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 Soft Earth All REM devices have a soft earth and as such the Earth must be connected to the terminal ‘E’. This provides the required path to earth. It is not sufficient to have the 0V earthed on the 24V powered devices as these are separated. 3-1.
Innotech Device Network Cabling Installation Instructions Figure 3-3: REM Network with Repeater EXAMPLE 2: This example shows a GENIIELD controller with a network of REM’s and an IR11 repeater fitted. As in section one, once a repeater is installed there are effectively two networks and each must have the EOL jumpers fitted. NOTE Both ends must have the EOL jumpers fitted.
Innotech Device Network Cabling Installation Instructions Figure 3-5: REM Network with Repeater in the Middle of the run EXAMPLE 4: This example shows a GENIIELD controller with a network of REM’s where there is a repeater fitted and it is located in the middle of a run. 3-2 Sub System Network The Sub System Network is a sub network that connects to the Innotech primary network via a gateway. The Sub System Gateway IG01 is a data concentrator for the Sub System Network.
Innotech Device Network Cabling Installation Instructions 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 different pin spacing to the primary network terminals and while they look similar, they are not, and can’t be interchanged. 3-2.
Innotech Device Network Cabling Installation Instructions 3-5 End of Line Termination (EOL) All devices on the Sub System Network have EOL jumpers and these must be fitted correctly. This is shown in the figure below. There are many variations to network layouts. The following 4 examples provide a guide to correct jumper application. These are similar to the REM network.
Innotech Device Network Cabling Installation Instructions Figure 3-9: Sub System Network with IG01 in the middle of a run EXAMPLE 3: This example shows a Sub System Network with VAVMax and MiniMAX controllers where the IG01 is in the middle of the run. NOTE Both ends of a run must have the EOL jumpers fitted, it does not have to be a primary device.

Innotech Device Network Cabling INSTALLATION INSTRUCTIONS Chapter 4 - General Specifications
Innotech Device Network Cabling Installation Instructions 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.
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.
