3.1 Introduction
The RCP-GPIO Control Panel is designed to be controlled by the 3300
Controller. Operations of the RCP-GPIO Control Panel require that it be
configured at the system controller utilizing the Win3300 Control System.
The RCP-GPIO is configured as an RCP-MLDT panel using the first 32 of
the data keys to define its behavior.
General
All RCP-GPIO Control Panels in a system are custom configured at the
factory prior to shipment. The information needed to configure the control
panels comes from the System Design Guide filled out by the customer.
However, if the system configuration changes, the RCP-GPIO Control
Panels can be re-configured on site using the control system configuration
software.
3.2 General Purpose Inputs
The RCP-GPIO panel is equipped with 32 general purpose inputs. The
input circuit to the GPIO panel consist of an opto-isolated input. The
circuit requires that the LED input be driven with sufficient current to
trigger the opto-coupled transistor and be read by the panel. The input is
optically isolated from the input LED to electrically isolate the panel's
circuits from the input interface. The input connectors provide a current
source and ground so that an isolated switch closure (such as a relay) can
be used to activate the inputs as well.
The RCP-GPIO inputs are treated by the panel the same as a user acti-
vating a data key on an RCP-MLDT panel. When an input is activated on
the GPIO panel, the 3300 reads the event as if it were a key press. As a
key press, the panel can act to take a switch or change the destination
being controlled by the panel. Given the manner in which the keys are
configured, the activation of the input may do a number of actions.
The most common instance of operation is assigning a source to a data
key on the panel. When the input associated with the data key is acti-
vated, the panel switches the source to the destination that the panel is
currently controlling.
