•It is recommended that the unit be installed in a fully enclosed space constructed
of a suitable RF shielding material such as steel or aluminum, in order to provide
adequate RF shielding for the unit.
•Provide adequate clearance and ventilation for the unit.
•The SHoW DMX OEM Receivers are normally intended to be mounted on an
external wall or panel. The mounting hole pattern is provided in Figure 2.
•Care should be taken to match the recommended clearance distance from the
PCBA surface to the inside mounting surface, to assure proper position of the
display, access to the control buttons, and sufficient clearance between the
inside wall and components on the OEM Receiver.
•The recommended mounting panel thickness is 0.0625” - 0.125”.
•SHoW DMX OEM Receivers require antennas and should not be operated
without the antenna connected, and should only be operated with approved
antennas. A list of approved antennas is provided on page 4.
Power requirements
The OEM Receivers can either be powered with +5VDC regulated power or +7-36VDC
unregulated power. The total power requirement is 2 Watts.
•If you are powering the unit with 5VDC, you must set switch S3 position 6 to 5V
(up).
•If you are powering the unit with +7-36VDC, you must set switch S3 position 6 to
HV (down).
If the switch is set incorrectly to the 5V (up) position and you feed it higher
voltage the unit will be damaged.

As noted above, this switch must be correctly set to assure proper operation.
Operating the SHoW DMX OEM Receiver
Once installed and provided with appropriate power, the SHoW DMX OEM Receiver
operates basically the same way that a standard SHoW DMX 5610 or 5611 Receiver
works. A SHoW DMX Transmitter receives DMX or RDM data from a source and
broadcasts it via radio waves. The radio signal is picked up by the OEM Receiver and
converted back into wired DMX or RDM data. The OEM Receivers have all of the
SHoW DMX RDM capability, including RDM Responder and RDM Proxy features, and
may be controlled, configured and communicated with via RDM through the SHoW DMX
RDM Monitor.
Since the 5605/5606 OEM Receiver is configurable as a half duplex RDM Responder, it
is capable of transmitting as well as receiving when used in the RDM mode.
The CTI 5605 SHoW DMX OEM Receiver is the North American version and meets all
North American (FCC and IC) radio requirements. The 5605 OEM Receiver’s maximum
broadcast power output is 125mW FCC/395mW ETSI when equipped with the standard
CTI 7” 5dBi Antenna.
The 5606 SHoW DMX OEM Receiver is the international version and meets all North
American and CE radio requirements. The 5606’s maximum broadcast power output is
32mW FCC/100mW ETSI when equipped with the standard CTI 7” 5dBi Antenna. All
other controls and features are the same for both models.
As noted in the compliance section on page 5, OEM Applications of these City Theatrical
Inc. products are not to be considered compliant with agency requirements until the final

The SHoW DMX System
The SHoW DMX System is a complete wireless DMX/RDM lighting system, intended to
provide everything needed for general wireless DMX/RDM distribution, wireless control
and battery powered operation of lighting and stage effects, including costume and set
lighting and effects control, or any other application where wireless DMX/RDM control
and/or battery powered dimming or effects control might be needed. In addition to the
powerful but gentle wireless DMX/RDM distribution that SHoW DMX provides, the
SHoW DMX Three Channel 10A Dimmer serves as a versatile lighting control module,
providing three channels of 9-24VDC incandescent ISL and Linear dimming, Non Dim
control, and RGB LED control in a single feature-packed unit.
The SHoW DMX System includes the 5600 and 5601 Transmitters, the 5610 and 5611
Receivers The 5605 and 5606 OEM Receivers, and the 5620 Three Channel 10A
Dimmer. The 5600 Transmitter, 5610 Receiver, and 5605 OEM Receiver are designed
for use in North America. The 5601 Transmitter, 5611 Receiver, 5606 OEM Receiver
and 5620 Three Channel 10A Dimmer are certified for use in North America and also are
CE certified for use in Europe.
Setting up a SHoW DMX system is quite similar to setting up any DMX512 control
system. The principal thing to remember is that the Transmitter and Receiver(s) replace
DMX cable.
DMX System Flow
DMX 512 control data from any standard DMX 512 console is output to the SHoW DMX
Transmitter, which converts that DMX data to a radio signal and broadcasts it to the
SHoW DMX Receiver (or Receivers). The SHoW DMX Receiver takes the radio
broadcast and converts it back into standard DMX 512 data, which can than be
connected via standard cables to SHoW DMX 5620 Dimmers or any other DMX devices
such as moving lights, effects, etc. A typical DMX system diagram is shown in the
drawing below.

RDM System Flow
The SHoW DMX system also functions as an RDM Proxy system, by passing RDM
commands and replies back and forth between any connected RDM controllers and
responders. As with DMX, the principal thing to remember about RDM function is that
the Transmitter and Receiver(s) replace DMX cable. The main difference between DMX
and RDM operation is that RDM is a two-way system and so both Transmitters and
Receivers may need to function as wireless broadcasters or receivers of the RDM data.
In RDM mode, the SHoW DMX Transmitter converts incoming RDM commands to a
radio signal and broadcasts them to the SHoW DMX Receiver (or Receivers). The
SHoW DMX Receiver takes the radio broadcast and converts it back into standard RDM
data, then responds to it and/or passes it along to connected RDM responders, collects
any reply data from the RDM Responders, then converts the RDM responses back to a
radio signal which is broadcast back to the Transmitter. The Transmitter converts the
radio signals from the receiver back to wired RDM and sends it back upstream to the
RDM system manager, or may function as the RDM system manager itself. A typical
RDM system diagram is shown in the drawing below.

Frequency Hopping Spread Spectrum (FHSS) Radio Technology
The SHoW DMX radio utilizes a Frequency Hopping Spread Spectrum broadcast format
in the unlicensed 2.4Ghz Industrial Scientific and Medical (ISM) radio band.
FHSS broadcast format is a highly reliable and robust radio broadcasting technology that
utilizes the entire broadcast spectrum by rapidly hopping from channel to channel and
broadcasting briefly on each one. The order that the radio follows to hop from channel
to channel is called the hopping pattern, and transmitters and their receivers must be
synchronized on the same hopping pattern in order to communicate. There are many
channels available in the broadcast spectrum, so the radios can hop in many different
patterns, and there is little chance that FHSS radios operating on different patterns will
