GenII RMI

Digital / Remote Expansion Modules

This product has been superseded.

Replacement Product: Genesis II Controller V5

The Innotech GenII RMI Remote Module Interface provides an interface between the Genesis range of Digital Controllers and Remote Expansion Modules (REMs). It is connected to the Genesis Controller via the Local Expansion Module (LEM) port on the Genesis Controller and uses an RS485 communications link to connect to the Remote Expansion Modules.

Up to fifteen (15) individually addressable Remote Expansion Modules can be connected to a GenII RMI.
Incorporates robust isolated RS485 to allow reliable communications over long distances in electrically adverse signal conditions.
The Remote Expansion Modules can be located up to 500 metres away from the GenII RMI.
Requires only a single RS485 twisted pair screened comms cable link to the Remote Expansion Modules.
LED Indication of communications status.

The Remote Module Interface (RMI) provides a bridge between the LEM I²C serial communications on a Genesis Controller and the RS485 communications to the range of Innotech Remote Expansion Modules.

Application Notes
A Genesis Controller must have version 4 firmware installed to support Remote Expansion Modules. Version 4 Config Software must be used to configure a Genesis Controller that has Remote Expansion Modules connected to it.

The Genesis Controller can have only one GenII RMI Remote Module Interface connected to it.

Local Expansion Modules (LEMs) CANNOT be connected to a Genesis Controller that has a GenII RMI Remote Module Interface connected to it.

Power Supply

Voltage: 5V DC from the Genesis Controllers via the GenII LEM CABLE.

Inputs/Outputs

I²C Serial link to the Genesis Controllers via a 10 way dual pin strip.
RS485 Serial link to Remote Expansion Modules via a 4 way terminal block.

IIC Connection

Standard GenII LEM CABLE connection using 10 way ribbon cable. Cable length 100mm standard.

Terminal Identification:
RS485 Terminals (From left to right):

S1	=	Screen of incoming RS485 comms cable.
+	=	Positive of REM comms.
-	=	Negative of REM comms.
S2	=	Screen of outgoing RS485 comms cable.

Earthing Terminals:

Connection for electrical earth protection on RS485 comms cable.

Temperature Ratings

Storage 0 to 50°C non-condensing.
Operating 0 to 40°C non-condensing.

Enclosure
The GenII RMI Remote Module Interface is housed in a rectangular case made from flame retardant polycarbonate/ ABS plastic listed under UL94.

Colour: Grey
Mounting: DIN Rail

Installation

1 Mount the GenII RMI near to the Genesis Controller, the 10 way ribbon cable connecting them must not exceed 1 metre in length.
2 Mount the GenII RMI in a dry and clean location free of excessive vibration.
3 Wire in accordance with Innotech connection diagrams and local bylaws or refer to your local distributor.

Wiring

DO NOT connect ANY voltage to any terminals.
Power down the Genesis Controller before attempting to connect or disconnect the Remote Module Interface. Failure to do so may result in damage to both the Genesis Controller and the GenII RMI.
Connect the GenII LEM CABLE to the GenII RMI and Genesis Controller with the IDC connectors fitted to the ribbon cable. They are keyed so that they cannot be connected incorrectly.
Connect the RS485 comms to the GenII RMI to the comms terminals using the “Combicon” plug. Ensure that the polarity of the signal conductors is correct and follow the recommended connections for the screen as set out in the Connection Diagram supplied with the GenII RMI.
Connect an electrical earth cable to the terminals labeled “3”. This cable should be connected to the EARTH bus bar of the switchboard cabinet or to the electrical EARTH cable that earths the frame of the equipment the module is in. This “EARTH” connection provides protection for the comms circuit and comms cable screens only on the GenII RMI. It does not connect to the internal circuitry of the GenII RMI.

Comms Installation

If this device has only one RS485 comms cable connected to it, the cable screen must be connected to ‘Shield 1’. If there are two RS485 comms cables fitted, each screen must be connected to a separate ‘Shield’ terminal.
The two modules located at each end of the RS485 comms cable will have one RS485 comms cable connected and must have the Termination Jumper fitted. All other modules will have two RS485 comms cable connected and MUST NOT have the Termination Jumper fitted.
For a detailed description of the installation and connection of RS485 comms cabling, refer to the Genesis II Installation Manual.
