available via Crestron’s single-port C2ENET-1 and dual-port C2ENET-2 Ethernet
cards.
The PAC2 offers eight programmable analog and digital inputs as well as digital
outputs. There are eight normally open relays, isolated with MOV suppression.
The 32 Cresnet connectors that comprise the built-in 8-segment Cresnet hub are
located on the top of the PAC2 (NET A – NET H). When powered by the internal
supply or an external power supply, they expand the number of Cresnet devices that
can be connected to the PAC2. Each group of four connectors can electrically
support up to 32 Cresnet devices. When powered by the internal power supply, there
is a maximum of 50 watts (DC) available for all network devices connected to the
PAC2. The LEDs indicate communication on the Cresnet link.
The PAC2 provides external connections for both a back-up processor and
emergency over-ride closure signals. In the absence of Cresnet, a signal is generated
to switch power and communication of the Cresnet system to the back-up processor.
When the over-ride connection receives a contact closure, a signal is passed to the
lighting modules via the fifth wire of the interconnect cable, and the lights are turned
on to a programmed preset emergency level. They remain at this level until that
contact closure is removed.
For detailed information on the PAC2 input and output ports/connectors, refer to
“Ports/Connectors” on page 7.
The 2-Series operating system is vastly upgraded, 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
recompiled for the 2-Series. The real-time, preemptive multi-tasking/multi-threaded
operating system offers a FAT32 file system with long file names. The enhanced
SIMPL+™ instruction set is also fully compatible with existing Crestron SIMPL
Windows and SIMPL+ programs.
The PAC2 also provides true secure network communications, which is required for
today's corporate networks, automated residence systems, and the Internet. The Dual
Port 10/100 BaseT Ethernet card (C2ENET-2) will support dynamic and static IP
addressing and full duplex TCP/IP and UDP/IP. It offers a WAN port for Internet
and remote-location communications and a LAN port for local in-home use. A builtin firewall delivers network security with the Network Address Translator (NAT)
and router functions. The built-in Web Server uses memory storage on a compact
flash card for remote access and control.
Network Address Translation (NAT), available with the C2ENET-2 card, is a
method of connecting multiple computers on an internal network to the Internet (or
any other IP network) using one publicly visible IP address. Current implementation
for the Crestron 2-Series control systems includes a combination of the Network
Address Port Translator protocol (NAPT) and Bi-Directional NAT. NAT
functionality is included in the firmware of Crestron 2-Series control processors, and
enabled through a dual port Ethernet Z-bus expansion card such as the C2ENET-2.
NOTE: For specific details on NAT, including setup and configuration, refer to the
Network Address Translator (NAT) document (latest version of Doc. 6001). It is
available from the Downloads | Product Manuals section of the Crestron website

These connectors are used to supply 24VDC power to the built-in hub segments.
Each connector provides power to a segment pair—POWER 1 provides power to
segments NET A and NET B; POWER 2 provides power to segments NET C and
NET D; etc. Internal power is applied to a segment pair by plugging one of the
supplied 3-pin mini connectors with installed jumper wire into the appropriate
POWER connector. If the power needed for a hub segment exceeds the power
available from the internal supply, remove the jumper from the supplied 3-pin mini
connector and connect the 24VDC and ground wires from an external source to the
EXT and G pins.
For more details, refer to “Built-In Cresnet Hub/Repeater” on page 9.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
I/O
The I/O port has eight software programmable analog and digital inputs as well as
digital outputs. Digital outputs offer 250mA sink from maximum 24 VDC; catch
diodes for use with "real world" loads. Digital inputs are rated 0 – 24 VDC, 20K
ohms input impedance, logic threshold 1.25 VDC. Analog inputs are rated 0 – 10
VDC, protected to 24 VDC maximum, 20K ohms input impedance; pinprogrammable 2K ohms pullup resistor to +5V. For detailed information, refer to
“Slot 4: C2I-IO8” on page 32.
NOTE: Digital outputs are TTL values and may not work with devices requiring a
“dry” contact closure (e.g., low voltage motor controllers).

BACKUP NET INPUT
This connector (Crestron network port labeled 24 Y Z G) allows a backup control
system connected here via Cresnet cable to automatically take control of the Cresnet
network upon a failure of the internal processor. The connector is rated at 24VDC,
Class 2 power source. A 24VDC power supply is diode “ORed” with the internal
supply and will power the system if the built-in supply fails. Cresnet will switch over
upon a built-in watchdog detecting failure of the CPU. The FAULT LED indicates
the failure.
FAULT
Provides a dry contact closure fault signal to notify an external control system when
the PAC2 has a system fault. This output should be connected to a digital input of the
backup computer. The fault signal is active low. A fault is defined as the CPU not
interacting with Cresnet for 10 seconds. The watchdog will switch back if the backup
computer’s Cresnet is inactive for 10 seconds.
COMPUTER
This DB9F connector is used when programming with a PC. The port is modem
compatible. The modem and/or PC program cable (standard male to female straightthrough) is not supplied.
NET
This connector (typical Crestron network port labeled 24 Y Z G) electrically
supports up to 32 Cresnet peripherals. Note that there is a 50W maximum load rating
on the PAC2 internal power supply, which applies to this connector plus the 32 NET
connectors on the top panel. Refer to “Built-In Cresnet Hub/Repeater” on page 9,
and “Network Wiring” on page 16 for details.
Indicators
The indicators provided on the top panel of the PAC2 integrated control systems are
described below.
PWR (Power)
This LED illuminates when the unit receives power (from any source).
NET
This LED illuminates (blinks) when the central processing unit is processing or
communicating with Cresnet devices.
ERR
This LED illuminates when an error condition is detected. This may be the result of a
message from the system, a hardware or software failure, a missing/wrong card
placed in a slot, or a programming error. To decipher content, examine the message
available through Viewport.
FAULT
This LED illuminates when a fault signal is sent to notify an external control system
that the PAC2 has switched control to a backup system, since the main system was
detected to be inactive.
NOTE: The LAN LEDs are active only if the optional single port or dual port
Ethernet card (which is field installed) occupies the Z-BUS slot. LAN A is used for a
single port Ethernet card; LAN A and B are used for the dual port card.
LNK A, LNK B (LAN)
These LEDs illuminate when the Ethernet card has established a valid Ethernet
connection.
ACT A, ACT B (LAN)
These LEDs illuminate when there is communication (activity) at the respective port
on the Ethernet card.
Reset Buttons
Two buttons are provided on the top panel of the 2-Series integrated control systems.
Refer to the description of each below.
HW-R
Pressing this button initiates system hardware reset. (Same effect as disconnecting
and reconnecting power-reinitializes operating system and program.)
SW-R
Pressing this button alone momentarily while the system is running restarts the
program. Pressing this button in combination with the HW-R button performs a
system restart without reinitializing the program (refer to “Troubleshooting
Communications” on page 21).
Built-In Cresnet Hub/Repeater
The built-in Cresnet Hub/Repeater serves as a repeater, splitter, and wiring block.
The hub allows for 256 or more devices; 32 per segment (A-H) and distribution up to
3000 feet per segment.
There are eight independent segments, each with four Cresnet connectors wired in
parallel. Each segment has a dedicated driver/receiver for Cresnet communication. In
addition, there is a master NET port on the front panel. The eight NET (A-H)
activity LEDs illuminate when a device on the respective segment transmits data.
Segments that are not in use or have devices that are not polled by a SIMPL program
are logically ‘disconnected’ from the other segments in operation. The LEDs for
these segments are not illuminated.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
Power for the hub is supplied through POWER ports 1, 2, 3, and 4, to segment pairs,
as shown in the illustration on the next page. When power is applied, the LED
adjacent to the port is illuminated.
In the illustration above, one of the supplied 3-pin mini connectors with installed
jumper wire is plugged into the POWER 1 port. The PAC 2’s internal power supply
is connected to the INT pin; the port’s EXT pin is connected to the 24 pin of each
connector in the segment pair. Since the jumper connects the INT and EXT pins of
the port, 24VDC is supplied to each connector and the external network devices.
If the power needed for a hub segment exceeds the power available from the internal
supply (50 watts, max.), remove the jumper from the supplied 3-pin mini connector
to disconnect the internal power supply, then connect the 24VDC and ground wires
from an external source (Crestron 24 VDC - regulated power supply) to the EXT and
G pins.
NOTE: If a device or Cresnet network connected to a hub segment has its own
power source, do not make any connection to the applicable POWER port. Although
equipment damage is unlikely, Crestron does not recommend applying two power
sources to the same circuit.
Attach wiring per the latest revision of either the Network Interconnection Drawing
or the Mini Network Interconnection Drawing. The Cresnet or CAT5 cables can be
secured to the 32 supplied mini-phoenix connectors, which can be plugged into the
Cresnet hub ports.
On-Board Memory
The PAC2 has 36MB of built-in memory (non-volatile and volatile). A total of
36MB is broken down as follows: 4MB internal flash (non-volatile), 32MB DRAM
(volatile), and 256KB NVRAM (non-volatile memory). Flash memory contains the
file system inside the 2-series control engine. NVRAM contains information that is
retained after loss of electrical power. Volatile memory is lost after a power failure.
Refer to the lists on the next page for a breakdown of memory usage for programrelated information stored in the unit.
Internal 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 table on the next page
presents the structure of the overall file system.
Although the file system is case insensitive, the case is preserved to maintain file
checksums. The compact flash directory only appears when the compact flash is
inserted into the system. To reference files on the compact flash, prefix “\CFx\” to
any fully qualified path from the Windows environment. For example, if the file in
Windows is “\My Directory\My Subdirectory\My file.ext”, the complete 2-series
path for a file on the first Compact Flash slot (on-board) is:
Legacy directory used in ISYS panels to hold
display lists
The mounting point for the compact flash files,
where x is the number of the compact flash slot
(0 = on board slot, i.e., \CF0 refers to the onboard slot)
“\CF0 \My Directory\My Subdirectory\My file.ext”
Non-volatile
1. SIMPL+ Variables (Default if no options are specified, or using
"nonvolatile" qualifier or #DEFAULT_NONVOLATILE)
2. Signals explicitly written to NVRAM* (by symbols such as Analog
RAM, Analog RAM from database, Serial RAM, Serial RAM from
database, Analog Non-volatile Ramp, Digital RAM, etc.)
*Commonly used for presets (volume/lighting/dial #s).
NOTE: If you extract NVRAM values to a file (Viewport, File transfer | Save
NVRAM to File), to simplify restoring them in the event of file corruption or to
distribute to identical control systems, remember that NVRAM values are position
sensitive in the program. When saving the NVRAM is crucial to your application, it
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 that uses
NVRAM is placed before any symbols using NVRAM, the previously stored values
will not line up and your presets will have to be re-entered.
Volatile
1. Digital, analog and serial signal values
2. SIMPL+ Variables (if "volatile" qualifier is used, or
#DEFAULT_VOLATILE is used)
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.
