2.2 Receipt Inspection
The RCP-GPIO Control Panel is inspected and tested prior to shipment
from the PESA 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
PESA Customer Service at the telephone number listed in the front of this
manual.
Installation
Section 2
After 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.A. 19" equipment rack and use two rack units of space (3.5"). An 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. All mounting holes should be utilized and
the hardware be securely tightened.

2.3 Location and Mounting Continued:
All interconnection cables should be strain relieved and secured to the
equipment racks or other supporting structures. Failure to provide adequate 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. Align the control panel chassis with a slotted opening in the rack.
2. Install the bottom screws first.
Section 2Installation
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. Sequential 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 separately, 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.

2.8 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 Connector 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. A GND connection is provided on pin 3 of Input
Connector Two for utilization by user supplied equipment. Alternatively,
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.

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.
Operations Section 3
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 activating 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 activated, the panel switches the source to the destination that the panel is
currently controlling.

OPERATION

RCP-GPIO
3.3 General Purpose Outputs
The RCP-GPIO panel is equipped with 32 general purpose outputs. The
output circuit of the GPIO panel consists of a relay output closure. When
activated, the panel activates the relay coil causing the relay switch to
close.
The GPIO panel outputs appear as MLDT panel LEDs to the 3300 control
system. When the panel lights an LED, the GPIO panel activates the
associated output. These LEDs are lit when the source assigned to the
key is switched to the panels current destination. In this manner, tally
can be generated when a source is connected to a certain destination.
3.4 Panel Configuration
The RCP-GPIO panel is configured in the system as a RCP-MLDT panel.
The manner in which the panel is configured determines how the panel
inputs and outputs will function.
Section 3Operations
Address: Decimal number from 1 to 1023 which is used to distinguish
each panel on the panel communications bus. Address must match the
DIP switch settings on the rear of the panel.
Panel Name: Any eight alphanumeric characters. Currently used only by
the controller configuration program to provide a user friendly method of
referring to each panel.
Requester Code: A number from 1 to 65535, this value is used by panels that need to share locks and protects. This is usually set to the same
value as the panel address.
Priority: Priorities are used when a panel attempts to set or clear a
destination protect or lock. Since the RCP-GPIO does not lock or unlock
its destination, this field does not have any real application. A master
priority of 0 is sufficient for this panel.
Status Method: The utilization of the default status is required by the
RCP-GPIO Control Panel.
Default Status Level: Level to be statused by the GPIO panel. This
level is important since it is used in the determination of which general
purpose output is activated for tally.

Default Destination Group: Destination group to be controlled by the
panel when first powered up.
Level List: List of levels to controlled by the panel. Any level not assigned in the Level List will not be accessible to or affected by panel
operations.

Include Destination List: List of all destination groups controllable by the
panel. Not applicable to the RCP-GPIO panel.
Salvo List: List of all salvoes the panel can execute. Not applicable to
the RCP-GPIO panel.
Data Key Assignment List: List containing the assignment of all data
keys as configured by you. Though the RCP-MLDT allows 72 data keys,
the RCP-GPIO is only functional for the first 32 of those keys.
The RCP-GPIO panel uses only two of the data key types: Source and
Destination. Though the RCP-MLDT supports many other types of key
options, the other types should be avoided unless you have a very good
understanding of the RCP-MLDT and RCP-GPIO panels.
Salvo Key Assignment List: Since salvos are not accessible from the
RCP-GPIO panel, this list is not applicable and may be left blank.
Soft Keys: Since soft keys are not accessible from the RCP-GPIO panel,
this item is not applicable and may be left blank.
The following is an example of configuring the RCP-GPIO for two different
types of applications.

3.4 Panel Configuration Continued:
Configuring All Actions to be Taken on a Single Destination
If all actions initiated by the panel are to be taken on a single destination,
then the following is required for configuring the panel.
1. Enter a panel name. This is an optional name for your benefit that
allows you to identify the function of the panel.
2. Enter the address for which the panel is coded. This address matches
the binary encoded value on the DIP switch on the back of the panel.
3. Enter a requester code. Usually this is the same as the panel address.
Requester codes are used when locks and protects need to be shared
among a number of panels.
4. Enter the lock priority. Since this panel performs no lock actions, a
value of 0 (super user) is adequate.
Section 3Operations
5. Enter the status level. This is the level of control that is of most interest to the panel. It is the level of control that will determine the tally
that activates the GPIO panel outputs.
6. Enter the status method. The selection should be the default (DEF).
7. Enter the default destination. The selected destination is the destination on which all panel actions are taken.
8. Levels of control list determines which levels of control the panel will
take switches on. Selection of the ALL list will insure that actions are
taken on all levels of control.
9. Source, destination, and salvo include lists do not have any impact on
the operation of the panel. Selection of the ALL list is adequate for
these panels.
10.The data key list is the list that determines what switches will be taken
when a particular input is activated as well as what outputs are activated when a certain switch status occurs. Data key associations to
inputs/outputs are 1-to-1 so that data key #1 is associated with input
and output #1 on the GPIO panel, etc. In this configuration, data keys
are assigned desired sources (Source Key Type) that correspond to
each input/output that will be activated.

Given a configuration that has the source VTR 1 associated to data key
#3, when input #3 is activated on the panel, VTR 1 is taken to the destination controlled by the panel. The output associated with the source VTR1
becomes active.
If the same source is used more than once on a panel (i.e. assigned to
more than one data key) and is used for GPIO panel output activation, the
user will need to OR the switch closures together. The panel does not
guarantee which output will activate when the source is switched to the
panels destination.
The data key list only needs the first 32 data keys configured. Keys 3372 need not be configured.
11.Salvo key and soft keys are not used by this configuration. They do
not need to be configured on the panel.
Configuring Actions to be Taken on Different Destinations
The RCP-GPIO panel may be configured to initiate switches on different
destinations. Doing so has some limitations in that each input event must
go to two separate inputs. In addition, the use of the general purpose
outputs is limited as the panel only provides tally for one destination at any
one time.
1. Enter a panel name. This is an optional name for your benefit that
allows you to identify the function of the panel.
2. Enter the address for which the panel is coded. This address is coded
on the DIP switch on the back of the panel.
3. Enter a requester code. Usually this is the same as the panel address.
Requester codes are used when locks and protects need to be shared
among a number of panels.
4. Enter the lock priority. Since this panel performs no lock actions, a
value of 0 (super user) is adequate.
5. Enter the status level. This is the level of control that is of most inter-
est to the panel. It is the level of control that will determine the tally
that activates the GPIO panel outputs.

6. Enter the status method. The selection should be the default (DEF).
7. Enter the default destination. The selected destination is the destination that the panel controls coming out of reset. This will be used for
status until an input is activated on the panel.
8. Levels of control list determines which levels of control the panel will
take switches on. Selection of the ALL list will insure that actions are
taken on all levels of control.
9. Source, destination, and salvo include lists do not have any impact on
the operation of the panel. Selection of the ALL list is adequate for
these panels.
Section 3Operations
10.The data key list is the list that determines what switches will be taken
to a which destinations when a particular input is activated. When
configuring for this scenario, two successive data keys must be assigned for each input. The first key (lower number) is assigned the
destination (Destination Key) that will be switched. The second key is
assigned the source (Source Key) that is to be switched to the destination. (Note that the destination key must be the lower number key as
the panel reacts to lower key inputs before higher key inputs. Failure
to do this will cause the switch to be taken before the proper destination is selected.)
Given a configuration that has source VTR 1 to be taken to MONITOR 1
on an input event, MONITOR 1 is the destination assigned to key #1 and
VTR 1 is the source assigned to key #2. The input circuits to inputs #1
and #2 are paralleled. When the input is activated, the panel switches
control to the destination MONITOR 1 and then switches the source VTR
1 to MONITOR 1.
The data key list only need the first 32 data keys configured for 16 switching events. Keys 33-72 need not be configured.

4.1 Introduction
The RCP-GPIO Control Panel contains one printed circuit board assembly; the GPIO Interface Card. The GPIO Interface Card contains a microprocessor that controls the panel's operation and communicates with the
routing switching system controller. The GPIO Interface Card also contains the interface connections used by the external relays to the control
the routing switcher system. The following manual section contain a detailed description of the GPIO Interface Card.
4.2 GPIO Interface Card
The GPIO Interface Card contains all of the circuitry necessary to communicate with the system controller and to interface with 32 inputs and 32
outputs. The circuitry on the GPIO Interface Card may be divided into the
following sections: Power Supply, Microprocessor, Clock, Reset, and
RS485 Communications. The GPIO Interface Card also contains circuitry
which scans the inputs and activates the corresponding output relays. The
following paragraphs explain each section in detail.
Power Supply
The power supply circuit on the GPIO Interface Card consists of a 7805
+5V regulator and filter capacitors. Unregulated DC voltage (7.5 to 9 VDC)
is supplied by an external power supply via J65. The voltage regulator
(U39) reduces the voltage to 5.0 VDC. C10 and C9 provide filtering for the
input and output of the regulator. Bypass capacitors (0.1 uF) are scattered
about the assembly to provide power supply bypassing for the individual
integrated circuits (ICs). Unregulated voltage (Vext) is also provided to the
output relay circuits.
Microprocessor
The heart of the GPIO Interface Card is the Motorola 68HC11 microprocessor (U35). This IC contains the microprocessor and peripheral circuitry
used to operate the control panel. In addition, the 68HC11 contains a
PROM loaded with the software used to operate the control panel. The
68HC11 is operated in the multiplexed mode. In this mode port B (U35 pin
35-42) provides the address byte (A0-A2). Port C (U35 pins 9-16) provides
the data byte (D0-D7).

4.2 GPIO Interface Card Continued:
Microprocessor Continued:
During the first half of the bus cycle, port C presents the lower address
byte (A0-A2). This information is presented to U38 and remains stable until the beginning of the next bus cycle when KBD_SEL is driven high by
the processor. During the last half of the bus cycle port C presents data
during write cycles and accepts data during read cycles.
Clock
The master system clock is provided by oscillator U6 pin 8. SYSCLK is
available to the processor (U35 pin 7). The frequency of SYSCLK is
7.3728 MHz. This value was chosen to provide an appropriate frequency
for the baud rate generator inside the 68HC11.
Reset
Section 4Functional
As with all microprocessors, the 68HC11 requires initialization during
power-up. The 68HC11 requires that the RESET pin (U35 pin 17) be held
low for 4064 cycles of E clock (2.2 mS @ 1.8432 MHz E clock). In addition
the RESET pin must be held low while VDD is below legal limits to protect
the internal EPROM register contents. A Maxim MAX690 chip (U34) performs the reset function for the 68HC11. The MAX690 monitors the supply
voltage and asserts RESET (U34 pin 7) whenever VCC falls below 4.5
VDC. The RESET signal is guaranteed to be asserted for a minimum of
50 mS after VCC rises above 4.75 VDC. This is more than adequate to
meet the 2.2 mS requirement of the 68HC11.
RS485 Communications
Communication between the panel and the system controller is accomplished by the 68HC11 internal serial communications interface (SCI). The
SCI is an asynchronous receiver/transmitter, sometimes referred to as a
UART. The RS485 standard is used for the electrical interface between
control panels and the system controller. A 75ALS176 (U37) chip is used
convert between RS485 and the levels required by the SCI. Transmit data
(TXD) is presented by the SCI on U35 pin 21. This signal drives the input
to the RS485 transceiver on U37 pin 4. Data received from the system
controller is converted to the appropriate levels by the RS485 transceiver
and is presented on U37 pin 1. This received data (RXD) signal is then fed
to the SCI receiver at U35 pin 20. Since the RS485 interface requires the
transmitter to be tri-stated when not is use, a third signal is required to enable/disable the RS485 transmitter.

4.2 GPIO Interface Card Continued:
RS485 Communications Continued:
The processor provides the TX_ENABLE signal under software control at
U35 pin 25. This signal is connected to the RS485 transceiver at U37 pin
3. When TX_ENABLE is asserted (high), U37 drives the RS485 bus (U37
pins 6 and 7 to J4 pins 1 and 3). When TX_ENABLE is negated (low),
U37 ceases driving the bus and allows other devices to drive the bus. During reset, the TX_ENABLE signal from the processor is initialized to an input and is not driven to a particular state. A pull-down resistor (R35) has
been added to ensure that U37 does not drive the RS485 bus during
power-up or other reset conditions. A shield connection is provided for the
RS485 bus on J66 pin 2.
LED Driver Support
The 68HC11 processor uses the internal synchronous peripheral interface
(SPI) under software control to drive the GPIO Interface Card's LED circuitry. LDATA is presented as serial bit stream on U36 pin 25. LCLK is
presented on U36 pin 24. U36 accepts LDATA on the rising edge of LCK.
The data stream generated is compatible with that required by National
MM5450 LED driver chips.
Inputs Scan
The GPIO Interface Card contains circuitry capable of scanning up to 64
inputs. The scan circuit is arranged as an eight row by eight column array.
While the scan circuitry is capable of serving 64 push-buttons, the GPIO
Interface Card has circuitry for 32 inputs. To scan the inputs, the microprocessor performs read cycles that enable KRD_SEL. This occurs for the
address range of 800h to FFFh. KRD_SEL provides an active low chip select for the bus transceiver (U1 pin 19). The three least significant address
bits (A0-A2) are connected to the input of the decoders (U38 pins 1, 2,
and 3). One of the eight active low outputs of the decoders is selected by
placing the appropriate address on the input of the decoders. Since partial
decoding is used, the keyboard circuitry is mapped to several addresses
within the KRD_SEL address range. The software in the microprocessor
only uses the lowest available addresses to access the keyboard.

4.2 GPIO Interface Card Continued:
Inputs Scan Continued:
Although the GPIO Interface Card only uses rows 0-3, the microprocessor
still scans all 16 rows. Each row of push-buttons contains up to eight individual switches. Example: KB_ROW0 will simultaneously enable inputs 1-
8. If any of these inputs are activated, the active low signal will be passed
through the input jumpers to one of the eight column signals (KB_COL0
through KB_COL7). If the input is not activated the column signal will be
pulled high by resistor pack RP1. The KRD_SEL signal also enables U1 to
place the KB_COL signals on the data bus. Thus, by performing a read
cycle at address 800h, the microprocessor can determine the state of inputs 1-8 by looking at the state of data bits D0-D7. If input 1 is activated,
then D0 will be low. Likewise, if input 2 is activated, D1 will be low. The
status of the entire input array may be determined by performing successive reads of each row of the array.
Section 4Functional
Output Relay Activation
While the GPIO Interface Card contains circuitry capable of activating up
to 34 output relays, the GPIO only uses 32 of the output relay driver circuits (one per output). The drive for the output relay circuits is provided by
U36 (MM5450V LED Driver). The microprocessor sends a serial data
stream to the MM5450V LED driver using the LDATA (pin 25 of LED
driver chip) and LCLK (pin 24 of the LED driver chip) signals. The enable
signal (pin 26 of the LED driver chip) is always asserted (active low). The
output current used drive each LED is enabled by the brightness pin of the
LED driver (pin 21). Resistor R323 sets the current flow through the output
relays. The LDATA line is latched into the LED driver chip on the rising
edge of LCLK.

5.4 Corrective Maintenance Continued:
Factory Repair Service
If desired, equipment items or assemblies may be returned to the PESA
factory (transportation prepaid) for repair. Refer to the General Assistance
and Service Information Sheet found in the front of this manual. Call the
PESA Service Department (the phone number is listed on Service Information Sheet) for a RMA number prior to shipping an equipment item to
the PESA factory for repair.
NOTE
PACK THE EQUIPMENT SECURELY AND LABEL WITH THE CORRECT ADDRESS.
PROPER PACKAGING SAVES MONEY. THE SMALL AMOUNT OF EXTRA CARE AND
TIME IT TAKES TO CUSHION A PART OR UNIT PROPERLY MAY PREVENT COSTLY
DAMAGE WHILE IN TRANSIT. MAKE CERTAIN THAT THE ADDRESS IS BOTH LEGIBLE AND COMPLETE. FAILURE TO DO SO OFTEN RESULTS IN DELAY OR EVEN
LOSS.
Troubleshooting
Troubleshooting the RCP-GPIO Control Panel requires the routing
switcher system to be used as a test fixture. The RCP-GPIO Control
Panel will not function except as part of routing switcher system. The only
troubleshooting which can be accomplished without opening the control
panels is to check input power (from plug-in power supply).
To open a control panel for troubleshooting, remove the front cover and
disassemble the unit as far as required to gain access to the component
side of the circuit assemblies. Place the disassembled panel on a nonconductive surface and arrange the parts so the unit can be operated. You
must be able to check the operation of the inputs and outputs while observe the resulting status. You must also have sufficient access to the
circuit assemblies to measure voltage or observe waveforms.
Procedure: Put the RCP-GPIO Control Panel through the operating
sequence as described in operation section of this manual. Refer to Section 3.
If the control panel is unresponsive, there may be a power problem
or the microprocessor on the GPIO Interface Card is not operating.
