GPI-6 INTERFACE MANUAL iii
IMPORTANT SAFETY INSTRUCTIONS
Please read and follow these instructions before operating a GPI-6 general purpose
inputs interface. Keep these instructions for future reference.
(1) WARNING: To reduce the risk of fire or electric shock, do not expose this
apparatus to rain or moisture.
(2) Do not use the apparatus near water.
(3) Clean only with a dry cloth.
(4) Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions. Install the GPI-6 interface according to the
directions in the Installation Chapter of this manual.
(5) Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that produce heat. Do not place naked
flame sources such as candles on or near the matrix.
(6) Do not defeat the safety purpose of the polarized plug or grounding-type
plug. A polarized plug has two blades with one wider than the other. A
grounding-type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for replacement of the obsolete
outlet.
(7) Protect power leads from being walked on or pinched particularly at plugs, at
convenience receptacles, and at the point where they exit from the apparatus.
Note: A “convenience receptacle” is an extra AC power outlet located on the back
of a piece of equipment, intended to allow you to power other equipment.
(8) Only use attachments/accessories specified by the manufacturer.
(9) Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
(10) Unplug the apparatus during lightning storms or when unused for long
periods of time.
(11) Refer all servicing to qualified service personnel. Servicing is required when
the apparatus has been damaged in any way, such as a power-supply cord or plug
is damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
Please familiarize yourself with the safety symbols in Figure 1. When you see
these symbols on a GPI-6 general purpose inputs interface module, they warn
you of the potential danger of electric shock if the module is used improperly.
Please read and follow these
instructions before operating
a GPI-6 general purpose
inputs interface.

GPI-6 GENERAL PURPOSE INPUT INTERFACE 1-1
OPERATION
INTRODUCTION
This chapter describes the GPI-6 general-purpose inputs interface. System
operators can use this chapter once the Eclipse system has been correctly installed
and the input controls have been assigned with the Eclipse Configuration System
programming software.
DESCRIPTION
The GPI-6 provides six general-purpose logic inputs into the matrix, allowing
external sources to trigger routing changes and other events through the matrix
system. Like the RLY-6, this interface is also connected through the separate
RJ-45 accessory data connector on the matrix frame.
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 ins and outs.
All of the RLY-6 and GPI-6 interfaces in the system are daisy-chained from the
GPI/RLY connection. The matrix system will automatically identify both the
type and "addresses" of every relay output or logic input.
The GPI-6 provides the following functions:
1. Senses six independent sets of logic inputs which can activate functions in the
matrix frame as defined by the configuration program.
2. DC isolation between the external device(s) and the system.
3. An LED indicator for each input that lights when the input is active.
Each GPI-6 interface input will sense a voltage between 5 to 45 volts of either
polarity. Over this voltage range the maximum signal current drawn by the card
will be 7 mA.
The LED indicators for each input actually indicate what the matrix system has
read from the inputs so that these indicators show that the interface is really
working.
A TEST pushbutton switch is provided for each input to allow local activation of
the software function associated with the input.
The front panel of the GPI-6 has six green LEDs to indicate the presence of an
input signal on a given channel. A seventh yellow LED indicates that the
module is communicating with the matrix. There is also a TEST pushbutton
switch for each input to allow local activation of the software function in the
matrix that the input is controlling.
The GPI-6 provides six
general-purpose logic inputs.
You can “daisy-chain” GPI-6
and RLY-6 units to provide
more inputs and outputs to
the matrix.

GPI-6 GENERAL PURPOSE INPUT INTERFACE
1-2
OPERATION
Once the GPI-6 is installed and configured there are no controls for day-to-day
operation. Activation of each individual input is indicated by LEDs.
The TEST switches for each input can be used to test the software function
associated with the input.
The yellow LED should be 'on' all of the time indicating that the frame is
communicating with the module.
CONFIGURATION
You configure the inputs with the Eclipse Configuration System programming
software. Refer to the Eclipse Configuration System Manual for more information.

GPI-6 GENERAL PURPOSE INTERFACE 2-1
INSTALLATION
INTRODUCTION
This chapter describes the installation of the GPI-6 general purpose inputs
interface and wiring to the external devices. The GPI-6 occupies one slot in an
interface frame. Connections are made to the matrix and other modules via an
8-pin RJ-45 connector, and to the external devices via two DB-9M connectors.
There are no adjustment controls for the GPI-6.
INSTALLATION
To install the GPI-6 interface module in the IMF-3 or IMF-102 interface frame,
select a slot to install the interface in.
1. Remove the blank plates from the front and rear of the slot in which an
interface module will be installed.
2. Install the interface module in the appropriate slot. Advance the front half the
interface module along the guides in the front part of the slot until it connects
to the midplane connector. Advance the rear half of the interface module
along the guides in the rear part of the slot, until it connects with the
midplane connector.
3. Install the provided screws on the front and rear panels of the interface module
you have just installed, to secure the interface in place in the frame.
The rest of the installation consists of connecting the GPI-6 unit to the matrix
and to either the control input or to the 'daisy-chain' output of another RLY-6 or
GPI-6 unit.
WIRING
The following sections describe connecting a GPI-6 module to the matrix and
external devices.
TO MATRIX
To connect the GPI-6 to the matrix, plug one end of a RJ-45 cable into the
GPI-RLY INTERFACE connector on the back of the matrix. Plug the other end
into the top RJ-45 (CH. A MATRIX) connector for the GPI-6.
To connect an additional GPI-6 interface, plug one end of a short RJ-45 cable
into the lower RJ-45 (CH. B MATRIX) for the first GPI-6. Then, plug the other
end into the top RJ-45 (CH. A MATRIX) connector additional GPI-6.
Additional GPI-6 interfaces are added in the same way, using "daisy-chain"
wiring. If there are multiple GPI-6 modules, the inputs in the first module are
numbered 1 to 6; in the second module 7 to 12, etc. RLY-6 modules can be
mixed in this 'daisy-chained' scheme. The maximum combined length of all the
2

GPI-6 GENERAL PURPOSE INTERFACE
2-2
RJ-45 cables should not exceed 20 feet (6 meters). Figure 1 shows an example of
“daisy-chain” wiring.
Figure 1: “Daisy-Chaining” GPI-6 and RLY-6 Interfaces
TO EXTERNAL DEVICE
To connect external devices to the GPI-6 interface, use the two DB-9M
connectors on the rear cable assembly panel for the interface. Figure 2 shows the
pin assignment of these connectors as viewed from the frame side of the
connector.
If a DB-9F is plugged into the connector labeled CH. A I/O, inputs 1-3 are
available on that connector. The connector labeled CH.A I/O has inputs 4-6. In
Figure 2, the labels on the pins apply to either connector.
