CRMX-PD and -PR family
DMX and RDM enabled transmitter and receiver
modules.
Rev. C – September 18, 2009
1 General
The CRMX-PD family is the future of wireless DMX and RDM distribution – a wireless
system that communicates reliably with perfect fidelity. CRMX-PD is the most powerful
wireless lighting control system on the market, with ground breaking features to ensure
unrivalled reliability. CRMX-PD distributes DMX and RDM with full frame integrity
and provides range and reliability that surpass all other systems available today.
The CRMX-PD cards are designed to be small enough to fit into any standard fixture or
controller and have an interface that easily connects to existing user interfaces. CRMXPD cards are also compatible with W-DMX™ equipment for easy integration into
legacy systems. CRMX™ is trademarked, patent pending, CE approved and FCC
approval pending as of April 2009.
Two main families in the CRMX range of OEM products are found:
• CRMX-PD, DMX enabled transmitter and receiver modules.
• CRMX-PR, RDM enabled transmitter and receiver modules.

6 User interface
LED
A user interface may be created using a normally open momentary switch for operation and a
LED for status indication. A green power indicator LED is found onboard which is lit if a DC
power level within specified range is present, see Figure 2 on page 2
Note! The user interface is mandatory for proper operation of the CRMX-PD cards.

Figure 3 Location of power indicator LED
The switch found in Figure 2 on page 2 is used to operate transmitters and receivers which is
done by closing the switch and follow the timing requirements below. The switch should pull
pin 7 to ground when closed. Pin7 is pulled high by a resistor when the switch is opened.
Transmitter mode Switch timing Logic level
Idle Open High
Link receivers 50ms ↔ 3s Low
Unlink all receivers >3s Low
Receiver mode Switch timing Logic level
Idle Open High
Unlink transmitter >3s Low
The LED indicator pin is a 3,3V output capable of driving 20mA.
An appropriate series resistor must be used to limit the current output from the pin to
maximum 20mA.
LED indication is depending on receiver or transmitter and is illustrated below.

9 Testing the CRMX OEM
In order to demonstrate the performance of the CRMX OEM in comparison with
other wireless control devices, we recommend performing the following simple
tests:
To demonstrate coexistence
Reliable communication is possible because CRMX OEM neither interferes, nor is
interfered by other WLAN equipment. To demonstrate, place two laptops next to a
light fixture which has a CRMX OEM card installed. While the light fixture is in
operation, digitally transfer a file between the two laptops via a wireless network.
This utilises WLAN frequencies and the effects of interference can be observed
during the transfer. With other wireless control devices, the transfer will be slow
and jerky, or even impossible. However with the CRMX OEM installed, the
transfer will be smooth, demonstrating that CRMX OEM does not interfere with
other WLAN equipment, and that coexistence between the different devices exists.
- We recommend Windows Messenger or Windows File Sharer as a file transfer
program. Transferring a file between two laptops, as opposed to streaming a
video on the Internet, is advised as this reduces complications arising from
external factors such as Internet or website connectivity
- A large file size is also recommended (>30MB) so that the transfer time is
lengthened and the effects during the transfer can be observed more easily.
- A larger number of laptops, as well as other WLAN devices such as routers
and access points, may be used to simulate an environment with crowded radio
frequencies.
To demonstrate full frame integrity
Full frame integrity means that packets of data, or updates, are not lost during
transmission. CRMX OEM ensures full frame integrity by using an error
correction algorithm that is able to faithfully regenerate lost packets. There are two
methods to demonstrate this:
1. Using LED lighting fixtures
Set the LED lighting fixture with CRMX OEM to flash quickly. Connect a second
identical LED fixture by cable to the same controller and same DMX start address.
Because full frame integrity is supported, the LED lights respond with no delay
compared to the wired LED fixture. However, with other wireless control devices,
the difference in flashing speed of the fixture can be observed to be slower.
Coupled with a latency of 5ms, the CRMX OEM is thus especially suitable for
lighting fixtures where fast response times are required, such as LED lighting
fixtures.
- LED light fixtures are used is because the response time of the LEDs are short,
allowing for the effect of a lost packet to be observed.
9(11)
- Several LED light fixtures may be used so that any lost packets can be easily
detected when the lights are seen to be out of sync.
2. Using 16-bit lighting fixtures or lighting fixtures with multiplexing
Full frame integrity can also be observed in lighting fixtures that use 16-bit pan
and tilt controls or multiplexing. A lost packet will be clearly noticeable in the
form of jerky movements of the fixture. Being built to be compatible with future
lighting fixtures, CRMX OEM ensures reliable wireless controls. As advanced
lighting fixtures using 16-bits and multiplexing become increasingly sought after,
CRMX OEM is ready to support them every step of the way.
- 16-bit lighting fixtures or fixtures with multiplexing functions are used as the
effects of a lost package is more significant and hence easier to observe
