Introduction
Features and Functions
The Crestron® 2-Series Professional Media Controller with RF (MC2W) is designed
for smaller home and commercial systems. The MC2W provides connectivity for
communication and control of Cresnet®, one-way wireless (RF), and third party
devices. With speed, power, and memory, the 2-Series control systems are ideal for
enhanced applications like media help desks, videoconferencing, distance learning,
and entertainment facilities.
Operating on either 418 MHz or 434 MHz, the MC2W can receive RF signals
(containing commands) from Crestron wireless user interfaces (touchpanels or
keypads). The MC2W then sends the commands to the appropriate device. Refer to
“Slot 8: C2I-MC2-CNRFGWA” on page 28 for information on selecting the
operating frequency.

IR SERIAL OUT
This connector provides four ports for IR TTL level or serial interface. Each output is
labeled S (signal) and G (ground). Infrared output is rated up to 1.2 MHz, at data rates
up to 115K. An individual UART on each port allow simultaneous firing of all ports.
Serial protocols include one-way RS-232.
NOTE: Transmission levels on the infrared – serial output connectors are in the 0 to
+5VDC range, which may not be compatible with all RS-232 devices.
NOTE: A port can be used for either IR or RS-232 communication, not both.
IR IN
This connector provides a 3-position mini connector for use with the CNXRMIRD
Infrared (IR) Detector. It is used to receive standard RC5 IR codes (such as those
transmitted by the Philips
certain devices manufactured by Sharp Electronics Corporation.
The RC5 code is a 13-bit code that has a 5-bit group, 7-bit command group and 1
stop-bit. It contains a bit to distinguish between start and repeat codes. The RC5 code
has a uniform duration of all bits. A transition in the middle of the time interval
assigned to each bit encodes the logical value. A '0' is encoded by a high to low
transition and a '1' by a low to high transition. This is also called a 'bi-phase' code.
The CNXRMIRD that ships from Crestron requires some modification before use
with the MC2W. THE CNXRMIRD ships with a mini phone jack that cannot be used
with the 3-position connector on the IR IN port of the MC2W. To modify the
CNXRMIRD to connect to the MC2W:
Pronto, and many universal remotes) as well as codes from
1. Snip the mini phone jack from the CNXRMIRD.
2. Using a voltmeter, determine which wire connects to the Tip, Ring, and
Shield of the mini phone jack.

These two 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. Both ports are Cresnet Network Poll
Accelerator ready.
NOTE: The Cresnet Network Poll Accelerator allows a 2-Series control system to
maintain a fast response time (high-speed communications) between the control
system and a large number of Cresnet devices. For more information, refer to the
latest revision of the Network Poll Accelerator Operations Guide (Doc. 6087).
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

This connector is used for expansion to Cresnet peripherals. This connector can also
serve as a 24V power source to Cresnet devices when the MC2W is powered by the
external power pack, PW-2410RU. There is a 14 Watt maximum load rating for the
Cresnet power output when used with the included power pack PW-2410RU. Refer
to “Network Wiring” on page 12 for details. If the external power pack is not used,
the MC2W can receive power from a Crestron power supply from this connector.
NOTE: An optional power pack (PW-2420-RU) provides 38 Watts to Cresnet
devices when connected to the MC2W.
NOTE: In larger system configurations that require more than the 38 Watt load
capacity supplied by Cresnet (when using optional PW-2420RU power pack),
disconnect the +24VDC Cresnet wire from the MC2W and provide the +24VDC
power to the peripheral devices by an alternate source. Refer to page 14 for more
information.
NOTE: Interface connectors for the NET, Infrared-Serial, I/O, and Relay Output
ports are provided with the unit.
24VDC, 2.0A (Power Supply)
This female connector can be used to supply 24 VDC power to the MC2W from the
included external power pack, (model PW-2410RU) or the optional power pack
(model PW-2420RU).
When power is supplied to the MC2W through this connector using the included
external power pack, 14 Watts are available to Cresnet devices through the NET
connector. When using the optional PW-2420RU power pack to power the MC2W,
38 Watts are available to Cresnet devices through the NET connector. This is
typically used in small installations.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
NOTE: When power is supplied through this connector, Crestron recommends
disconnecting the +24 VDC on the Cresnet connector.
NOTE: Use care in wiring installations to avoid applying 24 VDC power to Cresnet
wiring from multiple sources.

Memory
The MC2W has 36MB of built-in memory (non-volatile and volatile). The total of
36MB is specified as follows: 4MB flash (non-volatile), 32MB SDRAM (volatile),
and 256KB NVRAM (battery backed up). Flash memory contains the file system
inside the 2-series control engine. Non-volatile memory contains information that is
retained after the loss of electrical power. Volatile memory is lost after a power
failure. Refer to the lists below for a breakdown of memory usage for programrelated information stored in the unit.
Flash
1. SIMPL Program
2. SIMPL+ Modules
3. Operating System (.cuz file)
The 4MB flash memory consists of approximately 1.5MB used for firmware (.cuz
file), and approximately 2.5MB available for the SIMPL program and SIMPL+
modules. The files that reside in flash conform to a flat directory structure. The
following table presents the structure of the overall file system.

Although the file system is case insensitive, the case is preserved to maintain file
checksums.
Non-volatile (NVRAM)
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.)
NOTE: If you extract NVRAM values to a file (creating an NVRAM disk via the
Crestron Viewport command, 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. The
timing of a NVRAM save is crucial to your application, it is recommended to place
Operations Guide - DOC. 6143 2-Series Professional Media Controller with RF: MC2W • 9
2-Series Professional Media Controller with RF Crestron MC2W
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
Volatile (SDRAM)
1. Digital, analog and serial signal values
2. SIMPL+ Variables (if "volatile" qualifier is used, or
#DEFAULT_VOLATILE is used)
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.
NOTE: SDRAM is internal to operations and is not available to the programmer.
