Crestron AV2 & PRO2 2-Series Integrated Dual Bus Control System
Integrated Dual Bus Control
System: PRO2 & AV2
Description
NOTE: A summary of differences between the 2-Series and CNX generation
control systems is provided in the SIMPL™Windowshelp file. Search for "What's
new in the 2-Series".
Functional Description
The 2-Series Control Engine is a completely new solutions-driven control
technology that is at the very heart of the new PRO2 and AV2 Integrated Control
Systems. 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.
The breakthrough 2-Series control engine is based on the new 257 MIPS, 32-bit
Motorola ColdFireprocessor. Onboard 36MB memory is enhanced with a 4GB
expansion slot that supports off-the-shelf Type II compact flash memory and the
IBM Microdrivehard disk drive, allowing on-board storage of program and
touchpanel files, room and equipment profiles, upgrades, databases, and schedules.
Crestron's unique dual bus system, with its high-speed I/O bus architecture, provides
blazing fast throughput, system wide. This dual bus architecture also permits upgrade
to new, second generation, higher performance expansion cards, while still using
existing cards and software programs. The 40Mb/s Y-BUS supports existing CNX
control cards and serves as the pipeline for IR, serial communications, and relays.
The 300Mb/s Z-BUS is designed for super high-speed control card applications such
as 10/100 Ethernet, USB, USBII, FireWire, disk drive arrays and more.
The 2-Series also provides true secure network communications, which is required
for today's corporate networks and the Internet. A Built-in Firewall delivers the
ultimate in security, with Network Address Translator (NAT) and Router functions.
The Dual Port 10/100 BaseT Ethernet card supports dynamic and static IP addressing
and full duplex TCP/IP and UDP/IP. It offers a WAN port for Internet and corporate-
wide communications and a LAN port for room use. The built-in Web Server uses
memory storage on a compact flash card for remote access and control.
Operations Guide - DOC. 5957 Integrated Dual Bus Control System: PRO2 & AV2 •1

2-Series Integrated Dual Bus Control System Crestron AV2 & PRO2
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
easily 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.
Configuration Differences
The PRO2 delivers speed, power, and massive memory. Expansion capabilities
include one Z-BUS and three Y-BUS slots. High performance front panel
diagnostics and monitoring make the PRO2 ideal for sophisticated control of even
the most complex audio, video, lighting, security, and HVAC systems. The AV2 is
the cost-competitive option in Crestron's 2-Series line of integrated dual bus control
systems. Fully expandable with one Z-BUS and optional three Y-BUS slots, it is the
budget-conscious choice for control. Refer to the table below for a concise list of
configuration features.

5. Align and reposition cover over slot.
6. Tighten the screw.
Bussing Strip Installation
The 2-Series integrated dual bus 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.
2. 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.
3. 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.
4. 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.
5. Securing a tie wrap around the bussing strip is a useful way to strain
relieve the wires connected to the terminal block.
Network Wiring
The four-wire network cable is used to power Crestron devices. Before making any
four-wire network connections, refer to the network interconnection after this
paragraph and the cautions that follow.

CAUTION: Possible equipment damage if miswired.
CAUTION: Exceeding the power output (maximum 50W) of the 2-Series
integrated dual bus control system can result in system shutdown or a blown fuse.
NOTE: Do not power up system until all wiring is verified. Care should be taken to
ensure date (Y,Z) and power (24,G) connections are not crossed. Data "Y" was data
"+". Data "Z" was data"-".
NOTE: The cable consists of 1-#18 AWG twisted pair, tinned copper 1-#22 AWG
twisted pair with shield, tinned copper. There are six twists per foot per pair. The
jacket is teal color and labeled "CRESNET" every two feet. Liberty Wire carries the
cable (reference: CRESNET) and it is available in plenum or non-plenum versions.
NOTE: Each 2-Series integrated dual bus control system has one 4-pin network
connector. Use the following Crestron products to interconnect to other devices
within a network (some permit network testing):
- CNTBLOCK, Network Terminal Block
- CNHBLOCK, Multi-Type Network Distribution Block
- CNXHUB, Cresnet Hub/Repeater
- ST-CNB, SmarTouch/Cresnet Terminal Expander
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 = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF

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 table after this paragraph.

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: When daisy chaining network units, always twist the ends of the incoming
wire and outgoing wire which share a pin on the network connector. After twisting
the ends, tin the twisted connection with solder. Apply solder only to the ends of the
twisted wires. Avoid tinning too far up or the tinned end becomes brittle and breaks.
After tinning the twisted ends, insert the tinned connection into the network
connector and tighten the retaining screw. Repeat the procedure for the other three
network conductors.
Hardware Hookup
Refer to the hookup diagram on the next page and aside from attaching power last,
complete the connections in any order. Refer to "Network Wiring" on page 14 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.
NOTE: Since the plug on the power supply cord is used to disconnect power from
the unit, the socket-outlet shall be installed near the equipment and shall be easily
accessible.
