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 interfaces,
the inputs in the first interface are numbered 1 to 6 for GPI 1; in the
