Introduction
1.2 General Description
The RCP–48X is designed to provide an economical solution for installa-
tions requiring fast, intuitive operation. It is a button-per-source or destina-
tion panel featuring direct take operation for up to 16 levels of control of a
router destination. This panel is recommended for applications requiring
minimum keystrokes and a limited number of sources for a limited number
destinations. The RCP-48X can access one or more router destinations.
There are two control pushbuttons on the right. One allows the operator to
Protect or Lock the assigned destination while the other allows the opera-
tor to select an individual Level(s) to be controlled or display the panel
address.
This panel comes packaged in a standard 19 inch, one rack unit (1RU)
chassis requiring only 1 1/2 inches of depth, making it suitable for tight
locations. The unit is powered by a 7.5VDC Plug-in-the-Wall type power
pack and communicates with the System Controller via a Standard RS485
Interface.

RCP-48X Installation
2.1 Introduction
This section details RCP-48X installation procedures. The following topics
are discussed:
• Receipt Inspection
• Location and Mounting
• Polling Address
• Control Panel/Controller Interconnection
• Power connections
2.2 Receipt Inspection
The RCP–48X was inspected and tested prior to leaving the PESA fac-
tory. 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.
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-48X has been designed to fit in a standard E.I.A. 19" equipment
rack and uses 1 rack unit of space (1 3/4"). An area should be selected
where temperature does not exceed 40°C inside the equipment rack, and
where air can circulate freely. The unit should be mounted in an area
convenient to control and power connections. Sufficient space must be
provided behind the rack to allow for the control and power cables. All
mounting holes should be utilized and hardware tightened securely. All
cables should be strained relieved and secured to racks or other support-
ing structures. Failure to provide adequate cable support can result in
cables separating from connectors. If cable runs are to be stored under an
elevated floor, they should be tied to the racks as a guide. If cables are
run along the floor, do not allow them 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.

Location and Mounting Continued:
2.4 Polling Address
For the controller to identify a particular control panel, a specific device
number or polling address must be assigned to each panel. Valid polling
addresses are in the range of 1 to 128. Systems requiring more than 128
panels are possible with enhanced controllers, refer to your Pesa Sales
Representative for details. The appropriate binary number is entered into
the control panel by setting a 10-position DIP switch to the 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 6, 8, and 10 in the
"ON" or "1" position. See Figure 2–2.

Operations
3.1 Operations of the RCP–48X
Introduction
The RCP–48X is controlled by the RC5500 Controller. Operations of the
RCP–48X require that it be configured at the controller and have the
appropriate polling address assigned. Connections and power up proce-
dures should be performed on each panel controlled.
General
All RCP–48X panels in a routing switcher system are custom configured
at the factory prior to shipment. The information needed to configure the
panels comes from the System Design Guide filled out by the customer.

Section 3
RCP–48X Operations
Breakaway operation allows you to select an input to be switched to an
output on one or more specific levels. Assumptions: Panel is currently in
Direct Take mode (default mode) and no level has been selected for break-
away (Level/Disp. LED is not illuminated or blinking).
To Make a Breakaway Switch: Results:
Depress Level/Address Key Level/Address Key lights.
Panel enters Level Select Mode.
Data Keys represent Levels.
Depress Data Key associated Data Key(s) selected light to show
with level(s) you wish to breakaway level selection(s).
Depress Level/Address Key again Level/Address key blinks.
Panel returns to Direct Take Mode but
with Level(s) selected for breakaway.
Data Key whose associated input
matches the current status on the
selected level(s) will be illuminated.
Depress the Data Key associated The destination controlled by the
with the input you desire on the panel will be switched to the input
level(s) selected assigned to the Data Key pressed for

page 3.3
RCP–48X Operations Section 3
Data Keys: 48 Data Keys are located towards the left of the panel. Data Keys are associated with
sources or destinations in Direct Take mode and levels in the Level Select mode. The source/destination
assigned to each Data Key is configurable from the controller.
Function Keys: Two function keys are located to the far right of the panel: Protect / Lock and Level
/ Display Address. Each function key works as a toggle; the primary function is listed first, followed by
the secondary function. NOTE: The primary function is executed when the key is held down less
than 2 seconds. The secondary function is executed when the key is held down more than 2
seconds.
The RCP–48X has 2 Modes of Operation:
Direct Take - Selects sources to be switched to the destination controlled by the panel by depress-
ing associated Data Keys. Switch requests are sent immediately. Direct Take is the default mode;
deselecting the Level Select mode will always return you to the Direct Take mode. The Level/
Address Key will not be illuminated if the panel is in Follow or blinking if you have selected
Breakaway level(s).
Level Select - Selects which levels are to be affected when selecting switches in Direct Take mode.
Enter the Level Select mode by depressing the Level/Address key for less than 2 seconds. The
Levels/Address key is illuminated in this mode of operation.
Default Status Level Status: Panel will always display the status of the Default Status
Level.
Default Destination Group: Destination group to be controlled by the panel on panel boot-up.
Default Status Level: The level that will be statused when panel is in Follow operation and status
is not determined by the Group Status (refer to the preceding Status Method description).
Level List: List of levels to be controlled by the panel. Any level not in the assigned Level List will
not be accessible to or affected by panel operations.
Key Assignment List: List containing the assignment of source/destination groups to each of the
Data Keys.
PANEL CONFIGURATION:
Address: Decimal number from 1 to 128 which is used to distinguish each panel on the panel
communications bus. Address must match the dip switch setting on the rear of the panel. Systems
requiring more than 128 panels are possible with enhanced controllers: refer to your Pesa Sales
Representative for details.
Panel Name: Any 8 alphanumeric characters. Currently used only by the controller configuration
program to provide a user-friendly method of referring to each panel.
Priority: Choice of 3 priorities: Master, Supervisory, or Non-Supervisory. Priorities are used when
panel attempts to set or clear a destination Protect/Lock. Only the panel which set a Protect/Lock, or
someone of higher priority can unlock a destination. The default setting is Non-Supervisory.
Status Method: The panel displays status differently based on whether the panel is set for Follow
(changing all levels assigned to panel) or Breakaway (changing only selected levels) operation. In
addition, you may select between 2 methods of displaying status when in Follow (NOTE: these
methods only apply when the panel is set for Follow operation):
Group Status: Panel will display status based on the Source Group which changed the cur-
rent destination. If the panel receives status due to a Breakaway change request, or due to a
change made elsewhere in the system, the panel will display the status of the Default Status
Level (refer to the Controller Operations Manual for more details).

RCP–48X Operations Section 3
Breakaway Statusing
LED Illuminated Solid (not blinking) - The current status matches the source assigned to the Data
Key for the highest priority level selected (level 1 is highest priority) and the source(s) assigned to
the Data Key for other levels selected either match the current status or are not configured.
LED Blinking - The current status matches the source assigned to the Data Key for the highest
priority level selected (level 1 is the highest priority) but the source(s) assigned to the Data Key for at
least one other selected level does not match the current status.
No LED Illuminated - The current status does not match the source assigned to any Data Key on
the highest priority level selected (level 1 is the highest priority).
STATUSING:
Status by Group Status
LED Illuminated Solid (not blinking) - The current status matches the source(s) assigned to the
Data Key.
LED Blinking - The current status matches the source(s) assigned to the Data Key on some, but
not all , levels.
No LED Illuminated - The current status does not match the source(s) assigned to any Data Key.
Status by Default Status Level
LED Illuminated Solid (not blinking) - The current status matches the source assigned to the Data
Key for the default status level and the source(s) assigned to the Data Key for other levels either
match the status on the default status level or are not configured.
LED Blinking - The current status matches the source assigned to the Data Key for the default
status level and the source(s) assigned to the Data Key for at least one other level does not match
the status on the default status level.
No LED Illuminated - The current status does not match the source assigned to any Data Key on
the default status level.
NOTE: If the destination group being controlled by the panel matches a Destination Data Key, the
Destination Data Key's LED will be illuminated.
