Introduction
The Multiverse®Vero Transceiver 2.4GHz brings the advanced features of the Multiverse wireless
DMX/RDM system to outdoor installations for architecture and entertainment. The 7400-5903
Multiverse Vero Transceiver 2.4GHz contains a 2.4GHz radio for worldwide use.
The Multiverse Vero Transceiver is housed in a NEMA 4 / IP66 package that provides protection
from the outdoor elements. Its internal backlit LCD display simplifies setup and gives feedback on
system performance. Each unit comes with a dual band 2.5dBi Outdoor Omni-directional
Antenna.
7400-5903 Multiverse Vero Transceiver Features
•2.4GHz Radio
Transmit and receive on the 2.4GHz band for worldwide use.
•mDMX
mDMX is a form of DMX optimized for wireless broadcast that dramatically reduces
data being broadcast, thereby reducing unneeded radio energy.
•mRDM
Multiverse is able to broadcast RDM information without disrupting the DMX
broadcast. This feature is not available even in wired RDM systems.
•SHoW Key Security
SHoW Key is an optional three-digit code that can be added to the Multiverse SHoW
ID that will prevent any other system set on the same SHoW ID from interfering with
your system.
•Forward Error Correction
Allows the Receiver to detect and correct errors that may occur in the wireless
transmission of data.
•Ultra Low Latency
Total average system latency of 4ms.
•Adaptive Spread Spectrum Frequency Hopping
Adaptive Spread Spectrum Frequency Hopping identifies and masks off hopping
channels that contain interference, replacing them in the hop sequence with alternate
channels.
•Adjustable Output Power
Sometimes an application calls for the most available broadcast power, but many
entertainment systems can utilize lower output power to reduce detrimental effects on
other radio systems in the venue, reduce reflections, and improve performance.
•User Selectable SHoW IDs
City Theatrical has always produced wireless DMX products that allowed the user to
select the optimum transmission method. Users may select full bandwidth hopping,
hopping limited to a section of the spectrum (including areas of the spectrum outside of
the Wi-Fi range), or adaptive hopping.

About SHoW ID
Choosing and setting a SHoW ID is an important part of the Multiverse system. SHoW ID is a
number that describes the portion of the spectrum on which the broadcast will take place (such as
2.4GHz), the area of that band where the broadcast will be directed (such as full band, low portion
of the band only, high portion of the band only, etc.), and several other factors that influence the
broadcast. Those factors are combined into a number called the SHoW ID. See the SHoW ID
chart on page 10 for a full explanation.
Using A Spectrum Analyzer To Choose A SHoW ID
It is a good practice to utilize a device such as City Theatrical’s P/N 5988 RadioScan™
Spectrum Analyzer to analyze the spectrum in the area of the broadcast. RadioScan is a
900MHz and 2.4GHz spectrum analyzer, utilizing a hardware dongle and accompanying software,
that enables you to easily visualize radio energy that is otherwise invisible to you. Using
RadioScan helps you create a broadcast plan that optimizes the available spectrum in your area,
and helps prevent interference with other mission critical radio devices near you.
RadioScan will guide you in creating the optimum broadcast plan for your installation by helping
choose the best SHoW ID.
In this image, RadioScan has helped to choose a SHoW ID in the upper end of the spectrum.

Page 10 of 15
If you do not have RadioScan, devices like smartphones often have simple Wi-Fi visualizers
which can help guide you to a more open area of the 2.4GHz spectrum.
Choosing a SHoW ID
In a single universe system with a Multiverse Vero Transceiver used as a transmitter and one or
more Multiverse Vero Transceivers used as receivers, simply choose a SHoW ID and enter that
SHoW ID into the user interface of the transmitter and all receivers. The universe number must
match on transmitter and all receivers.
Here is a closer look at the SHoW ID numbering system:

If multiple wireless
systems need to operate
with the same data rate
and band this value will
change the hopping
pattern to minimize
overlapping between the
two systems. Can be any
number from 0 –9 (not all
bands have all Hop
Patterns).
Note: Not all combinations of digits are possible and unused numbers are reserved for future use.
Universe
Multiple universe systems can be created by adding additional Multiverse Vero units as single
universe transmitters. Separate universe numbers must be used for each additional group of
transmitters and receivers. Any Multiverse Vero acting as a receiver that is set on a universe that
Is not being broadcast by a Multiverse Vero acting as a transmitter will show its universe in a
yellow color.

User Interface Icons
At the top of the main screen are several icons that indicate Multiverse Vero Transceiver 2.4GHz
status. These include:
•“TX” or “RX”
The Multiverse Vero Transceiver is designated as either a transmitter or receiver on
the Menu Screen (see below for instructions). Each unit will display either “TX”
(transmitter) or “RX” (receiver) depending on which mode has been selected. The “TX”
or “RX” symbol remains solid when DMX data is detected, and blinks if no DMX data is
being received.
•Universe/SHoW ID
The display of the SHoW ID and the universe can be toggled back and forth by using
the “up”and “down” buttons. Pressing “Enter” will select SHoW ID or universe for
editing and will commit the change when done.
•Signal Quality Bars
The signal quality bars give a visualization of signal quality as seen at the receiver.
The bars are not present when the unit is a transmitter. Four bars is excellent signal
quality, three bars is good signal quality, two bars is fair, and one bar is marginal.
•Restore Factory Defaults
Factory defaults can be restored by holding the “Menu” and “Enter” buttons while on
the main screen. Screen will flicker to signal when default process is complete.
Default settings are listed below.
Menu Screen
Pressing the “Menu” button takes you to the Menu screen. The Menu Screen displays different
information depending on whether “Mode”is selected as “Receiver”or “Transmitter”.
In “Receiver”mode (the default mode), the choices are
•Mode
Select receiver mode or transmitter mode. Default is receiver.
•Power
Output power may be user selected as Low, Med, Hi, or Maximum. It is a best practice
to use the least amount of output power to achieve a successful broadcast. This helps
to reduce reflections which can reduce signal fidelity, and to reduce any potential
negative effect on other radio users in the area. You can monitor signal quality via
RDM. Default is Maximum.
•Antenna
If a panel (P/N 5981) or Yagi (P/N 5982) antenna is used instead of the default omni
antenna, choose it on this menu for optimum performance and to remain in compliance
with FCC and other radio regulations. A P/N 5639 Gender Changer N(m) to N(m) is
required to use a panel or Yagi antenna.
•SHoW Key (Multiverse SHoW IDs only)

Page 12 of 15
The optional SHoW Key setting allows a user to enter a key to privatize their SHoW ID
from another system on the same SHoW ID. SHoW IDs and SHoW Keys need to
match in order for receivers and transmitters to talk to each other. Keeping your SHoW
Key private will provide a level of security to your Multiverse system from unauthorized
use. It is not recommended to use different SHoW Keys in a system that uses multiple
Multiverse Veros as Transmitters on the same SHoW ID. The range is 0 (Default) to
500.
Table 2: SHoW IDs and SHoW Keys
•RDM Traffic
The RDM Traffic setting determines whether RDM data is passed downstream of the
Multiverse Vero Transceiver. It does not affect whether the Multiverse Vero
Transceiver is detectable by devices upstream. It is recommended that RDM be
turned off before production situations as many DMX devices do not correctly handle
RDM data and may exhibit flickering or other undesired behavior. Default is Off.
•Backlight Timeout
The Backlight Timeout setting determines how long the LCD backlight will remain on
after the last button press. The timeout can be set to “Off”(backlight will never timeout)
or any interval from 10 seconds to 59 minutes 59 seconds. Default is 59 minutes 59
seconds. After a screen timeout, pushing any button will wake up the screen without
changing the screen selection.
•Backlight Level
Controls Backlight brightness. Range is 1%-100%. Default is 100%.
•Information
The Information screen shows the RDM UID, firmware versions present,
connection status, and the number of devices (receivers and fixtures) downstream.
In “Transmitter”mode, these additional choices are available:
•Termination
If the Multiverse Vero is at the end of the DMX run, set this setting to “On”. If more
DMX devices are wired after the Multiverse Vero, set this setting to “Off”.
•Error Correction
High noise environments can affect wireless DMX performance. Enabling Error
Correction adds additional information to the data packets to correct errors in slot data
that would have otherwise been lost, restoring DMX delivery back to near perfect
levels. The extra data reduces the number of slots that can be transported, Max
reduces slots by 50%, Med by 33%, Min by 25%. Only needs to be set at the
Transmitter. Default is Off.
