2-Series Integrated Control Processor

2-Series Integrated Control
Processor: CP2/CP2E

Introduction
Features and Functions
Crestron’s CP2 and CP2E 2-Series Integrated Control Processors, cost-competitive
options in Crestron's 2-Series line of integrated control systems, are designed for
smaller home and commercial network systems. Like all Crestron control processors,
the CP2 and CP2E units house the control system software program and provide
connectivity for communication and control of all devices on the network. The CP2E
is functionally identical to the CP2, with the exception that it also provides LAN and
Web access through its built-in 10/100 BaseT Ethernet port, which supports
dynamic/static IP addressing and full-duplex TCP/IP and UDP/IP protocols.
With speed, power, and massive memory, the 2-Series control systems are ideal for
enhanced applications like media help desks, videoconferencing, distance learning,
and entertainment facilities.

bit Motorola ColdFire processor. The 2-Series operating system is vastly upgraded
from Crestron’s X-generation products, yet compatible with existing Crestron
software and programming. A key feature is the new Crestron Compiler, which
allows any existing Crestron SIMPL™ Windows control program to be easily
recompiled for the 2-Series. The real-time, preemptive multi-tasking/multi-threaded
operating system offers a file system that supports long file names. The enhanced
SIMPL+™ instruction set is also fully compatible with existing Crestron SIMPL
Windows and SIMPL+ programs.

NOTE: The orientation of this connector is “upside down” compared to other
Crestron network devices (e.g., CNX-BIPAD8, CNX-RMCLV). Be sure the mating
Cresnet cable connector is properly aligned before attempting to insert it, to avoid
damage to the CP2/CP2E unit.
This connector (typical Crestron network port labeled G Z Y 24) is used for
expansion to Cresnet and SmarTouch peripherals. This connector can also serve as a
24W power source to the network when CP2/CP2E unit power is supplied through
the 24VDC power supply connector by an optional AC power pack (purchased
separately); otherwise, power to the unit is supplied through this connector. There is
a 24W maximum load rating for power output. Refer to “Network Wiring” on page
11 for details.

These three DB9 (male) software programmable, bi-directional serial ports are
available for RS-232, RS-422, or RS-485 communication, with hardware and
software handshaking. Speeds are rated up to 115,200 bps. All three ports are
Cresnet Accelerator ready. The Cresnet Poll Accelerator effectively increases the
network speed, fan-out, and device addresses by a factor of 8 for each Poll
Accelerator added to the system.
NOTE: The pinout of each 9-pin port is non-standard (refer to the table after these
notes, titled "Non-Standard COM Pinout"); it contains RS-422 pins in addition to
RS-232. This may result in a conflict with some equipment and therefore all nine
pins should not be used. Only the required pins for each communication type should
be connected. For RS-232 and –422, pins 2, 3, 5, 7, and 8 are wired straight through.
NOTE: Data Set Ready (DSR) and Data Terminal Ready (DTR) are not supported.
NOTE: To support RS-485, tie pin 1 (RXD-) to pin 9 (TXD-) and pin 4 (TXD+) to
pin 6 (RXD+) in the cable (refer to the table after this note, titled "COM Pinout to

24VDC
2.0A

This male connector can be used to supply 24VDC power to the CP2/CP2E from an
AC power pack purchased separately. (Refer to Optional Power Supply on page 13).
When power is supplied to the units through this connector, 24VDC, 24W is also
available to other Cresnet system devices through the NET connector. This is
typically done in small installations. In large system configurations, power is usually
supplied through Cresnet wiring to the NET connector.
NOTE: Use care in wiring installations to avoid applying 24 VDC power to Cresnet
wiring from an AC power pack as well as from a system device that contains its own
power supply. Although this condition should not cause any damage, Crestron does
not recommend it. In those network configurations that require more power than can
be supplied by Crestron’s Power Control Unit alone, disconnect the +24 VDC
Cresnet wire from those devices that will be powered by an AC power pack.

series control engine. Non-volatile memory contains information that is retained after
loss of electrical power. Volatile memory is lost after a power failure. Refer to the
lists below for a breakdown of memory usage for program-related information stored
in the unit.

Flash
The 4MB flash memory consists of approximately 1.5MB used for firmware, and
approximately 2.5MB available for SIMPL, SIMPL+, and Web pages. The files that
reside in flash conform to a flat directory structure. The following table presents the

is recommended to place all symbols and/or modules that use NVRAM at the
beginning of your program. When NVRAM (.nvr file) is re-installed, all the values
should line up with the program. If the program is modified, and logic is placed
before any symbols using NVRAM, the previously stored values will not line up and
your presets will have to be re-entered

DRAM
DRAM is used by the operating system for dynamic storage of variables, signals and
other constructs used at runtime. The actual amount of DRAM used at any given
time depends on the particular program that is running, i.e., usage is variable, or
dynamic, during normal operation.

Industry Compliance
As of the date of manufacture, the CP2/CP2E integrated control processors have
been tested and found to comply with specifications for CE marking and the
Australian Compliance Mark.

NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.

Setup/Installation
Rack Mounting
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The
following guidelines are provided to ensure your safety:
When mounting this unit in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.

NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit. (e.g., use of power strips).
Two “ears” are provided with the unit and must be installed so that it can be rack
mounted. Refer to the following illustration and complete the procedures below to
attach ears to the unit. The only tool required is a Phillips screwdriver.

Ear Attachment for Rack Mounting (CP2E shown in illustration)

Using a Phillips screwdriver, remove and retain the three side screws
closest to the front panel.

Position a rack ear so that its mounting holes align with the vacated
holes, and secure the ear to the unit with the three screws from step 1

Repeat the procedure to attach the remaining ear to the opposite side.

Bussing Strip Installation
The 2-Series integrated control system is supplied with two brass bussing strips to
facilitate commoning (linking) of multiple terminal block connections. The bussing
strips are constructed with four terminal block position, and may be trimmed to size
for various applications or different devices. One strip is supplied for each
8-position terminal block.
1.

To utilize the bussing strip, determine the number of relays to be
commoned for the equipment being installed. If less than four, the strip
can be trimmed to size with a pair of scissors or wire snips.

Loosen the terminal block screws and insert the first leg of the bussing
strip into the first common position on the terminal block. The strip
engages the other common positions automatically.

Remove approximately 1/8" of the jacket from the common wire and
insert the conductor into one of the terminal block common positions.
Tighten the terminal block screws to lock the wire and bussing strip
into place. Insulate the strip by folding a piece of ¾" wide vinyl
electrical tape (such as Scotch 33+) over the spine and as much of the
individual legs as possible. Excess tape at each end of the strip should
be pressed closed, then trimmed to within approximately 1/16" of the
end of the strip.

When wiring the remaining conductors, remove approximately 1/8" of
the jacket and insert the wires into the proper terminal block positions.
To prevent the possibility of electrical shorts, it is essential that these
conductors do not touch any uninsulated portion of the bussing strip.

Secure the wires connected to the terminal block with a tie wrap around
the bussing strip to provide strain relief.

Network Wiring
NOTE: When making wire connections, refer to the latest revision of the Cresnet
Network Interconnect Drawing (Doc. 5411). The document can be obtained from the
Downloads section of the Crestron website (www. crestron.com). Search for the
CRESNET.PDF files.
CAUTION: Exceeding the power output (maximum 24W) of the CP2/CP2E can
result in system shutdown or a blown fuse.
CAUTION: Possible equipment damage if miswired.
NOTE: The orientation of this connector is “upside down” compared to other
Crestron network devices (e.g., CNX-BIPAD8, CNX-RMCLV). Be sure the mating
Cresnet cable connector is properly aligned before attempting to insert it, to avoid
damage to the CP2/CP2E unit.
NOTE: Do not power up system until all wiring is verified. Care should be taken to
ensure data (Y, Z) and power (24, G) connections are not crossed. Data “Y” was data
“+”; data “Z” was data “-”.
NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE: For larger networks (i.e., greater than 28 network devices), it may be
necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality
throughout the network. Also, for networks with lengthy cable runs, it may be
desirable to add a hub/repeater after only 20 network devices.
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation

R < 40,000
L x PF

Where: R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).

The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the following table.

NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.

Hardware Hookup
Refer to the following hookup diagram and, aside from attaching power last,
complete the connections in any order. Refer to "Network Wiring" on page 11 when
making network connections.
NOTE: To prevent overheating, do not operate this product in an area that exceeds
the environmental temperature range listed in the table of leading specifications.
Consideration must be given if installed in a closed or multi-unit rack assembly since
the operating ambient temperature of the rack environment may be greater than the
room ambient. Contact with thermal insulating materials should be avoided on all
sides of the unit.
NOTE: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit's supply
input should be considered to prevent overloading the wiring.

2-Series Integrated Control Processor
Optional Power Supply
The units can be powered through the NET network connector, or by an optional
AC power pack (purchased separately). If an external power supply is to be used,
Crestron recommends its CNPWS-75 External Power Supply or PW-2420RU
Universal Power Pack, or equivalent.
NOTE: Use care in wiring installations to avoid applying 24 VDC power to Cresnet
wiring from an AC power pack as well as from a system device that contains its own
power supply. Although this condition should not cause any damage, Crestron does
not recommend it. In those network configurations that require more power than can
be supplied by Crestron’s Power Control Unit alone, disconnect the +24 VDC
Cresnet wire from those devices that will be powered by an AC power pack.

Programming the CP2 and CP2E
SIMPL Windows is Crestron’s graphical, Windows-based development tool for
programming control systems. The SIMPL Windows interface provides two
workspaces: the Configuration Manager, for configuring the control system,
touchpanels, and controlled network devices; and Program Manager, for designing
the logic and functionality of the control system.
In addition, you can use Crestron’s powerful Viewport utility to accomplish multiple
system tasks, such as uploading the program to the control system and performing

2-Series Integrated Control Processor

Crestron CP2/CP2E

Slot 1: C2Net-Device
The C2Net-Device slot enables the CP2 and CP2E to control up to 252 Cresnet
devices. Each Cresnet device is assigned a unique identifier called a Net ID, which is
a hexadecimal value ranging from 03 to FE.
To view the list of supported devices, expand the control system in the bottom pane
of System Views and double-click the C2Net-Device slot, or right-click and select
Add Item from the submenu. Supported devices include network control modules,
lighting modules and a variety of Crestron wired touchpanels.
To add a device to the system expand the C2 Net-Device slot and double-click the
desired Net ID, or right click and select Add Item from the submenu. Then select the
device you want to add. Alternatively, you can drag the device from the Cresnet
Modules folder onto the Net ID.
In Program Manager, the C2Net-Device symbol contains no signals; to program a
controlled Cresnet device, expand the C2Net-Device symbol in Program View. Then
drag the device to Detail View.

Slot 2: C2I-IR8
The CP2 and CP2E provide 8 output ports (A through H) that enable serial
communication in a variety of formats, including infrared and one-way RS-232. Of
course, different devices may require additional receiving equipment, cables,
adapters, etc.
To add an IR device to the system, drag the device driver from the Crestron or User
IR Database to a C2I-IR8 port.
To add an RS-232 device, drag the C2IR one-way serial driver from the Serial
Drivers folder to a C2I-IR8 port. Alternatively, you can double-click a C2I-IR8 port
and select the C2IR one-way serial driver (or right-click and select Add Item from
the submenu).
Next, double-click the serial driver to specify the communication settings that are
required by the device. These settings define the protocol that the controlled serial
device expects, and include the speed of data transmission (baud rate), error
checking (parity), and the number of data bits and stop bits. The exact protocol will
be described in the manufacturer's documentation.
NOTE: The C2IR serial driver, being one way, does not provide hardware or
software handshaking.
In Program Manager, the C2I-IR8 symbol contains no signals; to program an IR
device or serial driver, expand the C2I-IR8 card by clicking the plus sign in Program
View. Then drag the symbol to Detail View. (Alternatively, double-click the symbol.)

Crestron CP2/CP2E

2-Series Integrated Control Processor
Slot 3: C2I-IO8
The CP2 and CP2E provide eight I/O ports called Versiports, each of which can
function as a digital input, a digital output, or an analog input. Each Versiport has a
corresponding pullup resistor.
In Program Manager, drag the C2I-IO8 symbol from Program View to Detail View.
The symbol contains the following signals, arranged here according to mode:
Signals
Digital output mode
•

8 digitals: through

Digital input mode
•

8 digitals: through

Analog input mode
•

8 analogs: through

•

For each analog, one corresponding minimum change value:
through

All Versiport modes
•

For each Versiport, one corresponding pullup resistor:
through

Defining a signal puts the signal into the corresponding mode. For example, defining
the analog input configures that Versiport as an analog input. A Versiport can
only operate in one mode. That is, if you define you should not also define
.
Description
Internal configuration of a Versiport

Digital Output Mode
When a Versiport is operating in digital output mode, the output pin will be shorted
to ground on the rising edge of the corresponding signal (switch S1-B in the
Versiport diagram will be closed). When goes low, the output pin is driven to a
value of +5V (switch S1-B is open).

Operations Guide - DOC. 5980

2-Series Integrated Control Processor: CP2/CP2E• 15

2-Series Integrated Control Processor

Crestron CP2/CP2E

Driving the corresponding signal high can modify this behavior. This is
not recommended, though, since it will cause the output pin to float when goes
low.
Example 1 (recommended):
The signal is driven low or left undefined. When goes
low, Versiport 1 is at +5V. When goes high, Versiport 1 is shorted to
ground.
Example 2 (not recommended):
The signal is driven high. When goes low, Versiport
1 is floating. When goes high, Versiport 1 is shorted to ground.
Digital Input Mode
When a Versiport is operating in digital input mode, the corresponding signal
will go high whenever the C2I-IO8 detects that the Versiport is shorted to ground
(threshold < +2.5V).
NOTE: Here, as with digital output mode, the corresponding pullup resistor should
be enabled. That is, should be given the signal name 0 or left
undefined; otherwise the input will always read as logic low.
Example 3:
When Versiport 3 is shorted to ground, will go high. When Versiport 3
is not shorted to ground, will go low (so long as equals
0 or is undefined).
Analog Input Mode
In analog input mode, the Versiport is typically tied to a resistive load (such as a
humidity sensor) or a voltage source (both can be represented by box "A" in the
Versiport diagram).
When a resistive load is tied to a Versiport, the corresponding pullup resistor must be
enabled (again, this means that should be given the signal name 0 or
left undefined). This creates a voltage divider and provides a varying voltage level,
based on the current resistance of the sensor for the C2I-IO8 to read.
Example 4:
A resistive humidity sensor is tied to Versiport 1 (and is low
or undefined). will assume the corresponding analog value.
When a voltage source is tied to a Versiport, the corresponding pullup resistor should
be disabled (the only case where the default setting should be overridden). This
allows the C2I-IO8 to read the value of the voltage source directly.
Example 5:
A voltage source is tied to Versiport 1 and is given the
signal name 1. will assume the corresponding analog value (ranging
from 0 to 65535, or 0 to +10V on the input pin).
The C2I-IO8 does not propagate all changes in the analog values of its Versiports,
since this can lead to undesirable results if the input source is not clean or has jitter.
Rather, the signals should be used to specify a "minimum change"
value, such that the C2I-IO8 will not propagate the new value until it changes by
. (The default minimum change value is 2048.)
Example 6:

16 • 2-Series Integrated Control Processor: CP2/CP2E

Operations Guide - DOC. 5980

Crestron CP2/CP2E

2-Series Integrated Control Processor
A voltage source is placed on Versiport 1 and is set to 10
via an Analog Initialize symbol. The value of will not be propagated
until it changes by at least 10. If the current value is 500, then a new value
will not be reported until it changes to 510 or 490.

Slot 4: C2Y-RY8
The C2I-RY8 provides eight isolated relays for controlling low voltage contact
closure devices such as drapes, screens and lifts.
In Program Manager, drag the C2I-IO8 symbol from Program View to Detail View.
The symbol contains the following signals, arranged here according to mode:
Signals
•

8 relays: through

When a signal goes high, the corresponding relay closes for as long as the signal
remains high. When the signal goes low, the relay opens. If a signal is undefined, the
relay is open.

Slot 5: C2ENET-1 (CP2E Only)
The C2ENET-1 port enables the CP2E to control up to 252 Ethernet devices. Each
Ethernet device is assigned a unique identifier called an IP ID, which is a
hexadecimal value ranging from 03 to FE.
To view the list of supported devices, expand the control system in the bottom pane
of System Views and double-click the C2ENET-1 slot. Supported devices include
Ethernet control modules, PC and Web browser interfaces, and a variety of Crestron
Ethernet touchpanels. To add a device to the system expand the C2ENET-1 slot and
double-click the desired IP ID, or right-click and select Add Item from the submenu.
Then select the device you want to add.
In Program Manager, the C2ENET-1 symbol contains no signals; to program a
controlled Ethernet device, expand the C2ENET-1 symbol in Program View. Then
drag the symbol to Detail View. (Alternatively, you can double-click the symbol.)

About the IP Table
In order for the CP2E (or any Ethernet-enabled control system) to control devices via
Ethernet, the IP ID of the device must be associated with an IP address, and both the
IP ID and IP address must be entered into the IP Table of the control system.
You can create an IP Table in two ways. The first method is to double-click the
device in Configuration Manager to open the “Device Settings” window. Click the
“IP Net Address” tab and enter the IP address of the device in the “IP Address” field.
Repeat this procedure for all Ethernet devices in your system. This creates what is
referred to as a “default” IP Table. When the program is compiled and ready to be
uploaded to the control system, you will have the option to upload this default IP
Table.
The second method is to use the Crestron Viewport. This method is especially useful
on site, if you want to change one or more IP addresses without changing the
program.

Operations Guide - DOC. 5980

Select Functions | Setup IP Table.

Click Add and select the IP ID of the device from the drop-down list, then
enter the IP address.

2-Series Integrated Control Processor: CP2/CP2E• 17

2-Series Integrated Control Processor
3.

Crestron CP2/CP2E

When all the IP IDs and associated IP addresses have been added to the IP
Table, click Send IP Table to Control System.

As with all 2-Series control systems, the CP2E has the capability to function as a
peripheral device, or “slave”, in a master/slave arrangement with another control
system. Here the IP Table of the CP2E must contain just one entry, for the master
control system.
To access the IP Table of a “slave” CP2E, use the Setup IP Table command on the
Viewport Functions menu, as just described. The settings are as follows:
•

Enter the IP ID of the CP2E itself, as specified in the program of the master
control system and select OK. Notice that the “slave” CP2E is listed with
TRUE in the Master? column.

•

2) Enter the IP address of the master control system.

•

3.) Click the Set as Master check box.

When operating as a slave device, the CP2E can accept commands only from one
control system. Therefore, there must only be one entry in the IP Table.
For further information about e-Control applications, including basic concepts and
terminology, see Crestron’s e-Control Reference Guide, DOC. 6052, available in
PDF format on the Crestron website.

Slot 6: C2I-COM3
The CP2 and CP2E provide three serial COM ports (A through C) that enable RS232, RS-422, and RS-485 communication.
Each port has a built-in serial driver with communication settings that must be
specified in Configuration Manager: double-click a COM port to open the “Device
Settings” dialog box, and then click the “Serial Settings” tab. These settings define
the protocol that a controlled serial device expects, and include the baud rate, parity,
and the number of data bits and stop bits. In addition, a device might require
hardware or software handshaking, which controls the flow of data between two
devices. The exact protocol will be described in the manufacturer's documentation.
The Crestron database includes numerous serial devices, with default logic and preconfigured communication settings, that are compatible with the ports on the COM
card. Simply drag the serial device from the Crestron Database folder to one of the
ports on the COM card and click Yes when prompted to replace the built-in serial
driver for that port. In most cases, the default logic should be loaded as well.
In Program Manager, the C2I-COM3 symbol contains no signals; to program a serial
driver expand the C2I-COM3 card by clicking the plus sign in Program View. Then
drag the desired serial driver to Detail View. (Alternatively, you can double-click the
symbol.)

Converting Programs and Modules Created for
other Systems
A useful feature of SIMPL Windows is that you can convert a program created for
another type of control system, simply by changing the target to a CP2 or CP2E.
To do this you first open the program, and then replace the existing control system
with the CP2 or CP2E. That is, drag the CP2 or CP2E from the Control Systems
folder onto the existing control system in System Views, and click Yes when
prompted to confirm the replacement.

Operations Guide - DOC. 5980

Crestron CP2/CP2E

2-Series Integrated Control Processor
If the program contains SIMPL+ or User modules, the conversion might generate
error messages. This is because modules and programs often contain symbols with
“ambiguous” signals. For example, the inputs of the Serial to Analog symbol can be
defined as either analog or serial. Although X-Series processors support ambiguous
signals, the 2-Series processor requires all signal types to be strictly defined.
If the program you want to convert contains SIMPL+ or User modules, Crestron
recommends that you first convert each module before converting the larger
program. In this way, the compiler can resolve any ambiguous signals in the modules
and minimize errors when the larger program is converted.
Converting SIMPL+ Modules
1.

Open the SIMPL+ module you want to convert.

Choose the 2-Series processor as the target by clicking the toolbar
button, as shown in the following illustration.

SIMPL+ Toolbar

NOTE: Note that you can select both X and 2-Series as the targets, so that the
module will work for both types of control systems. However, you will be limited to
SIMPL+ keywords and functions that are supported on both systems. If you do not
choose a target, then the module may or may not work, depending on the constructs
that are used.
3.

Save and compile the module by clicking the Save and Compile
toolbar button; alternatively, click Save and Compile on the Build
menu (or press F12).

Converting User Modules
1.

Open the User module you want to convert.

Click Project | Edit Program Header.

Click 2-Series in the “Target Control System Classes” list box.
You can select other types of control systems as well, but then you will be
limited to symbols that are supported by all of these platforms. The module
may still work on unselected control systems so long as unsupported
symbols are not used. Selecting a control system means that you are
requiring the module to work there.

After you convert each module in a program, you can convert the program as
described previously: drag the CP2 or CP2E onto the existing control system in
System Views and click Yes to confirm the replacement.
For further information about compile-time errors and detailed explanations about
working with modules, refer to the SIMPL Windows online help file.

Establishing Communication with the CP2/CP2E
Before uploading a program to the CP2/CP2E or performing diagnostic functions,
you must connect the control system to the PC. With the CP2, this connection must
be serial; with the CP2E the connection can be either serial or TCP/IP.
Serial Connection
Connect the COMPUTER port on the control system to one of the COM ports
(usually COM 1) on the PC. Use a straight-through RS-232 cable with a DB9 male
connector on one end and a DB9 female connector on the other. Most commercially
available cables are acceptable; they should have at least 5 pins for transmit, receive,
ground, and hardware handshaking.
Open the Crestron Viewport and click Setup | Communication Settings to display
the “Port Settings” dialog box. Then click RS-232 as the connection type.
The PC communication settings specified here should match the protocol that the
CP2/CP2E expects. The settings are as follows:
•

Port = COM 1 through COM 8. Select the correct COM port on the PC.

•

Baud rate = 115200 (You can set the PC and the control system to a
different baud rate, by using the Functions | Set Baud Rate command.

•

Parity = None.

•

Number of data bits = 8.

•

Number of stop bits = 1.

CP2/CP2E.

To verify communication, click Diagnostics | Establish Communications (Find
Rack). This should display a dialog box that gives the COM port and baud rate.
TCP/IP Connection
Before you can communicate with the CP2E over TCP/IP, you must use the RS-232
connection just described to configure the unit’s TCP/IP settings.
1.

Open Viewport and click Functions | Set Control System IP Information.

Enter the IP address, IP mask and default router in the text fields. (All of
these terms are explained in detail in Crestron’s e-Control Reference Guide,
DOC. 6052, available as a PDF on the Crestron website.)

Click OK to set the new IP information.

Once you have assigned the IP settings, you can continue to communicate with the
CP2E using the RS-232 connection, or you can establish a TCP/IP connection.
For TCP/IP, use CAT5 cables with 8-pin RJ45 connectors to connect the LAN port
on the CP2E and the LAN port on the PC to the Ethernet hub. Alternatively, you can

Operations Guide - DOC. 5980

2-Series Integrated Control Processor: CP2/CP2E• 21

use a CAT5 crossover cable to connect the two LAN ports directly, without using a
hub.
Once the cable connections are made, open the Crestron Viewport and click Setup |
Communication Settings on the menu to display the “Port Settings” dialog box.
Then click TCP/IP as the connection type. Enter the IP address of the CP2E.

To verify communication, click Diagnostics | Establish Communications (Find
Rack). This should display a dialog box that gives the IP address and port number.

Troubleshooting Communications
Use the following checklist if communication cannot be established with the
CP2/CP2E.
1.

Verify that you are using the correct cables. As described previously,
an RS-232 connection requires a straight-through serial cable. That is,
pin 1 on one end is connected to pin 1 on the other end. Pin 2 connects
to pin 2, etc. With a TCP/IP connection, you must use a CAT5 cable
with 8-pin RJ45 connectors.

With a serial connection, verify that the correct COM port on the PC
has been selected. Some computers have more than one COM port;

some may be internal (e.g., for a modem). Consult the manufacturer’s
documentation for further information about the COM ports on your
PC.
3.

Check the ERR LED indicator on the front panel of the CP2/CP2E. If
this LED is illuminated, unplug the unit and reapply power after a few
seconds. If the LED illuminates again, call Crestron customer service.

With a serial connection, reset the control system as follows:
a.

Open Viewport and click Setup | Communications Settings to
display the “Port Settings” dialog box. Choose RS-232 as the

The Viewport console should display the message shown
above.

Release the SWR button.

Select Set Baud Rate on the Viewport Functions menu (or press
F8) and choose any baud rate from the drop-down list. This will
attempt to establish a connection at the indicated baud rate. If the
connection is successful, both the PC and the control system will
be set to the new baud rate.

Reinitialize the unit by recycling the power or pressing the HWR
button. If the connection is established, the Viewport console
should display some text and the or prompt.

Compiling and Uploading a Program to the Control
System
After you have completed your SIMPL Windows program you must compile and
upload the program to the control system.
To compile the program, simply click the Convert/Compile button
on the
SIMPL Windows toolbar, or select Project | Convert/Compile (you can also press
F12). A status bar will indicate the progress of the compile operation. After the
operation is complete, a dialog box will display information about the program such
as the number and type of signals, and memory usage.
The compiled program will be stored as an SPZ file in the same directory as the
source file. There are a number of ways to upload an SPZ file to the control system.
1.

Immediately after compiling the program you have the option to transfer
the file to the control system.

on the SIMPL Windows
Alternatively, click the Transfer button
toolbar, or open Viewport and click File Transfer | Send Program.

Click Browse, locate the SPZ file and click Open. This will display the
program's header information and enable one or both of the What to Send
check boxes. If the program does not contain any SIMPL+ modules only
the SIMPL Program check box will be enabled. If it does contain
SIMPL+ modules, then the SIMPL+ check box will also be enabled. Select
one or both check boxes and then click Send Program to begin the
transfer.

NOTE: Unlike X-Series processors, the 2-Series processor does not require a
permanent memory image. Also, the 2-Series adds the ability to automatically
retrieve the current program from the control system. Simply verify that the
“Retrieve Current Program before overwriting” check box is selected.
You can also click Check Program to display the header information of the
currently loaded program.
“Send Program” Dialog Box

24 • 2-Series Integrated Control Processor: CP2/CP2E

Another way to verify that the program has been transferred successfully is to select
Report Program Information on the Viewport Functions menu. Program
information is also displayed in the Viewport console whenever power is removed
and re-applied to the CP2/CP2E.

Uploading Web pages to the CP2E
The CP2E provides a built-in Web server for e-Control applications. The CP2E allots
2.5 MB of memory for “user files” such as Web pages, mailbox, and the compiled
SPZ file.
VisionTools Pro-e
In most cases, you will create a VisionTools Pro-e browser project to generate the
Web pages that will be uploaded to the CP2E. Whenever a browser project is
created, VT Pro-e automatically creates a folder with the name of the project and a
.web extension. This .web project folder itself contains a .Java subfolder, in addition
to all the HTML files that will be sent to the CP2E. In designing and creating a
browser project, keep in mind that you must assign an IP ID to all the project pages
and specify the IP address of the CP2E. (For further information on this procedure,
refer to the VT Pro-e online help file.)
SIMPL Windows
For each IP ID in the VT Pro-e browser project, there must be one corresponding eControl PC Interface symbol defined in the SIMPL Windows program. The PC
Interface symbol is one of the Ethernet Modules that can be dropped into the
C2ENET-1 card slot.
As with all Ethernet devices, the PC Interface must receive an entry in the IP Table
of the CP2E. Here the IP ID must match the IP ID that was assigned in VT Pro-e,
while the IP address must be set to localhost: 127.0.0.1.
Viewport
To transfer the Web pages to the CP2E, use the File Transfer | Send Web Pages
command.
The options are to send an entire project, only files that have changed, or a single
HTML file. With the “Transfer Entire Project” option, click OK when reminded to
select a default page, then browse to the appropriate VT Pro-e .web project folder.
Select the file that was designated as the “first” page of the project. This will be the
default Web page that is displayed whenever the IP address of the control system is
accessed by a Web browser. Click Open, and then OK to begin the transfer.
If any files in the VT Pro-e project change, the changed files can be transferred to the
CP2E without resending the entire project by choosing the “Only Transfer Files that
have Changed” option. Here again, browse to the .web project folder and select the
default page. Click Open, and then OK to transfer the changed files.
Finally, selecting Transfer Single File can send a single HTML file. Browse to the
file and click Open. Then specify the file’s relative path (from the root directory)
and click OK.

Uploading Touchpanel Projects via the CP2/CP2E
You can use a connection to the CP2 or CP2E to upload VisionTools Pro-e projects
to any Cresnet touchpanel. Compiled projects for TPS panels are contained in VTZ
files; projects for all other touchpanels are contained in HEX files.
Before uploading, open Viewport and click Diagnostics | Report Network Devices
to verify that the touchpanel is being detected by the control system. (As with any
network device, touchpanels must be identified by unique hexadecimal network IDs.
These IDs are set in the SIMPL Windows program.)
To upload a project:
1.

From VT Pro-e: Click the Project | Upload button
or click File | Upload Project.

on the toolbar,

From Viewport: Click File Transfer | Send Touchpanel or press
Alt+T.
2.

Select the network ID of the touchpanel, as set in SIMPL Windows,
from the drop-down list.

Browse to the HEX or VTZ file to be uploaded. If the file is a HEX
file, click Open to begin the transfer.
If the file is a VTZ file, choose the pages to send to the TPS panel. The
choices are as follows:
-

All Files in Project: sends the entire project.

Only Changed Files: sends only the files that are different
from those that are currently stored in the panel. Note that if
any pages in the panel are not present in the project, those
pages will be deleted from the panel.

Additional choices include Do not send graphic files and Do
not send sound files. These are often very large files that need
not be reloaded with every transfer.

Updating the Operating System
As with all 2-Series control systems, operating system files for the CP2 and CP2E
have a .cuz extension. You can obtain .cuz updates (when available) from the
software downloads area of the Crestron website. To download an update, click the
.cuz file and choose the Save to Disk option, then specify the directory where the
update will be stored.
NOTE: In some cases Microsoft's Internet Explorer may append a .zip extension to a
downloaded .cuz file. For example, a file called "C2-1008.cuz" may appear as "C21008.cuz.zip." If this happens, rename the file, removing the .zip extension.
To upload the new .cuz to the control system:
1.

Open Viewport and select File | Update Control System.

Browse to the .cuz file and click Open to start the transfer.

Battery Replacement
A Lithium battery is used to power the system clock within the CP2/CP2E. Under
normal conditions, it will last for approximately 10 years. In the event that the clock
fails, only an authorized technician should replace it. Refer to caution statement
below.
CAUTION: Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer's instructions.

Passthrough Mode
Passthrough Mode enables Viewport access to any serially controlled device on the
network. That is, it allows direct communication between the PC and a network
device (effectively "passing through" the CP2 or CP2E). While Passthrough mode is
running, the program currently in memory is suspended and will not execute. When
Passthrough mode is exited, the program resumes operation. The TX and RX LEDs
for the given port illuminate when in Passthrough mode.
Entering Passthrough mode for one of the internal COM ports reinitializes it, which
clears the data for that port.
To establish communication, click Functions | Enter Passthrough Mode. Then
select the connection type that exists between the CP2/CP2E and the device. The
choices are Slot (for devices connected to the control system via one of the card slots
on the back panel), Cresnet, or Ethernet. If the connection is through a card slot then
select the slot number from the Slot drop-down list. For Cresnet, select the Cresnet
ID of the device; for Ethernet, the IP ID.
NOTE: The IP ID and associated IP address of the Ethernet device must be listed in
the IP Table.
Specify the port (Port A through Port F) that the device is connected to, if applicable.
Next, specify the serial protocol that the device expects. The parameters include the
baud rate, parity, the number of data bits and stop bits, the protocol (RS-232, RS-422
or RS-485), and the settings for software or hardware handshaking. This information
is provided by the manufacturer’s documentation.
