CITY THEATRICAL Multiverse Receiver Card 2.4GHz 5906 User Manual
Safety NoticeThis product is designed for use in dry locations only. Exposure to rain or moisture may cause damage to the transceiver and increase risk of electrical shock.Check all external wiring before applying power.
While Multiverse Modules are circuit board mounted devices used by professional lighting manufacturers, City Theatrical’s Multiverse Receiver Card, 2.4GHz (P/N 5906) can be used by anyone to implement wireless DMX/RDM into their projects or equipment in a simple way. 5906 Multiverse Receiver Cards are full Multiverse receivers for the 2.4GHz band (P/N 5907 is for the 900MHz band) without the housing, XLR connectors, and user interface as used in wireless DMX receiving products like Multiverse Node and Multiverse SHoW Baby. Multiverse Receiver Cards include an internal antenna and a U.FL connection to an optional external antenna. Configuration is done via City Theatrical’s USB Configuration program for PC/MAC. This product is designed and built in the USA by City Theatrical.

Configuration for Wireless DMX (Basic Mode)
Basic Mode will describe wireless DMX reception with wired DMX output. In its simplest form, the receiver card receives multiverse wireless DMX/RDM and outputs DMX/RDM as a differential pair on pins 11 thru 13 of the interface connector. For Advanced Mode (see page 11), users can optionally turn on a 0-10V output and/or PWM outputs and set starting DMX addresses for them. In all cases, the user interface presented is the same.
The Multiverse receiver card can be configured with RDM through a Multiverse Transmitter, Multiverse Node, or Multiverse SHoW Baby, or with the USB connector using the free City Theatrical USB Configurator program. All settings can be changed via the USB connection. RDM settings are only appropriate to what an end user will need to adjust. Feature settings are set by the integrator via the USB connector only.An easy way to apply power to the Multiverse Receiver Card for configuration (before any connections are wired to the card) is through the USB Micro-B connection.
Configuring Using RDMTo configure using RDM such as with a City Theatrical DMXcat® , a City Theatrical Multiverse Transmitter, Multiverse Node, or Multiverse SHoW Baby must be used to broadcast to your Multiverse Receiver card, and RDM configuration is performed through the Transmitter with the Multiverse Receiver Card as a connected wireless device. See Resetting Factory Defaults below.
Configuring Using City Theatrical USB Configurator for PC/MacWhen connecting the USB Micro-B connector to a PC or MAC, the receiver card will act as a virtual serial port. Use the City theatrical USB Configurator program, downloadable from the CTI website, to configure the card. Using the USB Configurator program you can easily set the SHoW ID, optional SHoW KEY, output power, and make the selection of an external antenna if you are using one. Other settings not related to basic wireless DMX will be described in the Advanced Features section of this manual.
Resetting Factory DefaultsFactory defaults may be manually reset by holding the SHoW ID Selector Switch for five seconds. The four signal quality lights will flash in unison to show the completion of the reset. Factory defaults as seen on the City Theatrical USB Configurator program are seen below. These settings are found on the Basic Info tab and Manufacturer’s Settings tab in RDM.

Band LED/SHoW ID Selector SwitchThe 5906 can receive in either 2.4GHz SHoW DMX Neo mode or 2.4GHz Multiverse mode (for Multiverse 900MHz, use P/N 5907). The band LED indicates whether the receiver card is currently listening to a Multiverse SHoW ID (green) or a SHoW DMX SHoW ID (yellow). See Table 3 below.Pressing the SHoW ID Selector Switch button will first cycle through six Multiverse SHoW IDs, the Band light will be green and the ID light will cycle through the six ID colors in Table 4 below. If you continue pressing the SHoW ID Selector Switch the Band light will change to yellow and you will begin to cycle through the six SHoW DMX Neo SHoW IDs.

Rx Quality LEDs
There are four LEDs in this group that represent the quality of the wireless signal received. All four LEDs will be lit when the receive quality is at is maximum. Orient the antenna of the device to produce as many lit LEDs as possible. For best performance, at least two LEDs should be lit.

Faster data rates provide more DMX universes. Slower data rates travel longer distances and provide more immunity to interference.

- 0. Use full range
- 1. Use only low band channels
- 2 Use only mid band channels (available for 1Mbps only).
- 3 Use only high band channels
- 4 Use only extreme high band to avoid WiFi (2.4GHz only. May limit power output).
- 5 Adaptive hopping. Avoids busy channels by analyzing spectrum (2.4GHz only).
Note: Not all combinations of digits are possible and unused numbers are reserved for future use.Note: SHoW ID, SHoW Key (if used) and Universe must match between Transmitter and Receiver Cards.Figure 2: Multiverse SHoW ID
SHoW KeyThe 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 un-authorized use. It is not recommended to use different SHoW Keys in a system that uses multiple Multiverse Nodes as Transmitters on the same SHoW ID. The range is 0 (Default) to 500.

Output power may be user selected as Low, Med, Hi, or Max. It is a best practice to use the least amount of output power to achieve a successful show. You can monitor signal quality on the receiver’s user interface screen LED bargraph, or via RDM. Default iMax. Note: Output power on a receiver refers to RDM transmission.
Antenna SelectionThis value sets the onboard Multiverse Radio configuration to optimize for the antenna being used. In most situations the Multiverse Receiver Card, 2.4GHz will use the internal antenna. Only change this value if an external antenna is connected.
Configuration for 0-10V or PWM Output (Advanced Mode)
Advanced mode allows the use of 0-10V and PWM outputs, setting the starting DMX addresses for those outputs, as well as relocating LED indicators in remote positions.
0-10V FeatureThe 0-10V feature provides one 0-10V control signal output for controlling architectural lighting devices. This feature can either sink or source control voltages without the need to configure sink/source.
PWM FeatureThe PWM feature repurposes the receive quality LEDs into PWM outputs. These are low current control outputs and are not intended to drive lighting loads. The feature provides four PWM outputs. The PWM output is linear in respect to the DMX control input and has a resolution of 8 bits, using one DMX slot per output. Refer to Table 8 for DMX addressing.
