2.1 Introduction
This section details the RCP-GPIO Control Panel installation procedures.
The following topics are discussed:
 Receipt Inspection
 Location and Mounting
 Polling ddress
 Control Panel and Controller Interconnection
 Wiring the Control Panel Connector
 Terminating Cable Runs
 Power Connections
2.2 Receipt Inspection
The RCP-GPIO Control Panel is inspected and tested prior to shipment
from the PES factory. Upon receipt, please inspect the unit for shipping
damage. If damage is detected, notify the carrier immediately and hold all
packing material for inspection. If assistance is required, please contact
PES Customer Service at the telephone number listed in the front of this
manual.
fter unpacking, compare all parts received against the packing list. If the
unit is undamaged and all components have been received, proceed with
installation.
2.3 Location and Mounting
The RCP-GPIO Control Panel has been designed to fit in a standard
E.I. . 19" equipment rack and use two rack units of space (3.5"). n area
should be selected where the ambient temperature will not exceed 40°C
inside the equipment rack, and where air can circulate freely. The control
panel should be mounted in an area convenient to control and power
connections. Sufficient space must be provided behind the equipment
rack to allow for the control and power cables. When the RCP-GPIO
Control Panel is supplied as part of a system including interconnecting
cables, rack layout drawings are usually provided. While adherence to the
rack layout drawings is not required, it will ensure that the interconnection
cables are the proper lengths. ll mounting holes should be utilized and
the hardware be securely tightened.

ll interconnection cables should be strain relieved and secured to the
equipment racks or other supporting structures. Failure to provide ad-
equate cable support may result in cables separating from connectors. If
cables are to be run under elevated flooring, they should be laid out in
cable racks if possible and tied to the cable racks as a guide. If cables are
run along the floor, do not allow then to lay in the work area behind the
racks. Stepping or tripping on the cables may result in connections being
pulled free or wire breakage inside the insulation. Figure 2-1 illustrates
the chassis installation.
To install the RCP-GPIO Control Panel take the following steps:
1. lign the control panel chassis with a slotted opening in the rack.
2. Install the bottom screws first.
3. Install the top two screws.
4. Tighten all four screws securely.

2.4 Polling Address
For the system controller to identify a particular control panel, a specific
device number or polling address must be assigned to each panel. Se-
quential binary numbers (1 thorough 1023) are used for this purpose. The
appropriate binary number is entered into the control panel by setting an
internal 10-position DIP switch to the selected binary number. The DIP
switch is located on the Remote CPU Board and is accessible from the
rear of the unit. The panel address is normally assigned and entered at
the factory if the panel is purchased as part of a system and a design
guide has been completed by the user. If the panel is purchased sepa-
rately, the user may be required to set the panel address.
EXAMPLE: To select polling address 21, set switches 10, 8, and 6 to the
"ON" or "1" position. See Figure 2-2.

2.5 Control Panel/Controller Interconnection
Each control panel has a single 3-pin MT connector located on its rear
panel which is utilized for system communications to and from the control-
ler. Control panels are daisy-chained to a communications port on the
rear panel of the system controller or to a communications port on the rear
panel of the routing switcher containing the system controller. Use
shielded twisted pair cable for all control panel communication port con-
nections. See Figure 2-3.

2.6 iring the Control Connector
Should an additional panel be added to your system, it will be necessary
to wire the connector using shielded twisted pair cable and a 3-pin MT
connector using the following instructions. See Figure 2-4.
1. Remove approximately 1.5" of insulation from each of the two cables.
2. Remove approximately 0.5" of insulation from the black and red wires.
3. Twist together and insert the two black wire into position one. Crimp
down using a screwdriver.
4. Twist together and insert the two shield wires into position two. Crimp
down using a screwdriver.
5. Twist together and insert the two red wires into position three. Crimp
down using a screwdriver.

2.7 Terminating Control Cable Runs
Each cable run should be terminated with a 120 ohm, 1/4 watt 5% resis-
tor. The cable is terminated internally at the controller. See Figure 2-5.
1. Un-crimp the black and red leads in positions one and three.
2. Insert the resistor leads into positions one and three along with the
black and red leads.
3. Crimp down using a screwdriver.
4. The shield wire remains in position two.

2.8 Input Connection
The RCP-GPIO Control Panel provides 32 opto-isolated inputs. Each
control panel input utilizes two 3-pin Weco input connectors (Figures 2-6
and 2-7). The two 3-pin input connectors allow the user to utilize internal
power and an internal 390 ohm pull-up resistor which can be connected to
the anode of the opto-isolator by connecting pins 1 and 2 of Input Connec-
tor One together. Input Connector Two provides the user with an open
collector connection on pin 2 to be utilized as a contact closure by user
supplied equipment. GND connection is provided on pin 3 of Input
Connector Two for utilization by user supplied equipment. lternatively,
an external current limit resistor can be installed between pins 2 and 3 on
Input Connector Two and user supplied power to pin 2 on Input Connector
One to activate the corresponding output. The input opto-diode is rated
for a maximum forward current of 60 milli-amps.

2.9 Output Connection
The RCP-GPIO Control Panel provides 32 form " " relay outputs (Figure
2-8). Each control panel output utilizes one 3-pin Weco connector . Each
3-pin output connector provides; a signal ground connection (pin 3), a
relay wiper connection (pin 2), and a relay normally open connection (pin
1). The maximum voltage rating of the output relay contacts is 100VDC or
100V Peak to Peak C. The maximum current rating of the output relay
contacts is 1 continuous or 0.5 switched.

2.10 Power Connections
Power for the RCP-GPIO Control Panel is supplied by an external 7.5
VDC, 800 m power supply.
Remove the power supply from the box it was shipped in and check to
insure that no damage has occurred in shipping. Verify that the power
supply is rated for the proper C voltage (i.e. 115 V C or 230 V C) be-
fore connection to the C line voltage. The power connector can now be
plugged into the POWER IN connector on the rear of the control panel.
The power supply will immediately power the unit upon connection to the
C line voltage. See Figure 2-9.

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 syste controller utilizing the Win3300 Control Syste .
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 syste are custo configured at the
factory prior to ship ent. The infor ation needed to configure the control
panels co es fro the Syste Design Guide filled out by the custo er.
However, if the syste configuration changes, the RCP-GPIO Control
Panels can be re-configured on site using the control syste 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 fro the input LED to electrically isolate the panel's
circuits fro 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 sa e 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 anner in which the keys are
configured, the activation of the input ay do a nu ber of actions.
The ost co on 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.
