Wiring Schemes for a GPI-6 Interface Module

The GPI-6 input interface module provides connection for six programmable inputs to the matrix so that each input can control a predefined matrix function.

Multiple GPI-6 interfaces can be daisy-chained to provide connection of up to 60 inputs to the matrix. RLY-6 and GPI-6 modules can be mixed together up to the total limit of 60 items.

Five RLY-6 and five GPI-6 modules would provide 30 relays and 30 inputs for a total of 60 inputs and outputs.

Note: If both GPI-6 and RLY-6 interface modules are used, the GPI-6 interface modules must be placed first in the daisy chain.

Wiring the GPI-6 to the IMF-3 interface frame

To connect the GPI-6 to the matrix:

  1. Connect one end of an RJ-45 cable (eight wires with no reversal) into the GPI/RLY INTERFACE connector on the back of the frame.

  2. Connect the other end into the top RJ-45 (CH. A MATRIX) connector for the GPI-6.

To connect an additional GPI-6 Interface module:

  1. Connect one end of a short RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for the first GPI-6.

  2. Connect the other end of the cable into the top RJ-45 (CH. A MATRIX) connector for the additional GPI-6.

Additional GPI-6 Interface modules are added in the same way, using daisy-chain wiring. If there are multiple GPI-6 modules used, the inputs in the first will be numbered 1 to 6, second will be 7 to 12, etc.

RLY-6 modules can be mixed in this daisy-chained scheme. The maximum combined length of all the RJ-45 cables should not exceed 20ft. (6m).

Wiring the GPI-6 to external devices

To connect external devices to the GPI-6 interface, use the two DB-9M connectors on the rear cable assembly panel for the interface.

The image below shows the pin assignment of these connectors as viewed from the frame side of the connector.

Notes: If a DB-9F is plugged into the connector labeled CH. A I/O, inputs 1 to 3 are available on that connector.
  The connector labeled CH. B I/O has inputs 4 to 6. In the image below, the labels on the pins apply to either connector.

The image above shows you how to connect switches or contacts using the power source provided by the GPI-6 module or powering switches from external sources. Each input can be wired to be isolated from each other as a further variation.

Wiring the GPI-6 to an IMF-102 interface frame

The wiring of a GPI-6 interface that is placed in an IMF-102 interface frame is the same as the wiring for a GPI-6 interface placed in an IMF-3 interface frame.

The only difference is that an IMF-102 interface frame houses only two interfaces, and they are mounted horizontally rather than vertically in the frame.

Note: The IMF-3 rear panel and IMF-102 rear panel images show the differences between these interface frames.

For more information, see your IMF-102 and IMF-3 documentation.

Note: To define an input function, use the EHX configuration software (see your EHXdocumentation and EHX Help.
