599x Series www.citytheatrical.com 7 2 Introduction City Theatrical's newest version of the Multiverse® Modules provides unprecedented levels of data transmission in a tiny package, and at the lowest cost yet seen in the entertainment lighting industry for professional quality wireless DMX. Multiverse Modules are best suited for lighting equipment manufacturers who are interested in adding wireless DMX to their products. Due to low cost, increased data transport, and ease of design integration, the Multiverse Module marks the first time that the implementation of a wireless DMX chip in every DMX device is possible. The Multiverse Module is available in two frequency ranges, 900MHz (for use in the Americas) and 2.4GHz (for use worldwide). Each frequency version can include a PCB trace antenna or not. All versions have a U.FL connector to connect to external antennas. Consult Table 2 for part numbers. The implementation of Multiverse Modules is simple because they are available on reels for surface mounting. The engineer can opt to integrate in one of three ways: Minimal, Basic or Advanced. The Minimal Integration Method replaces the DMX input circuitry with the module. The Multiverse module will deliver DMX/RDM directly via TTL UART signals. In this configuration, the Multiverse module will appear as a separate RDM device from the OEM product. This method provides an easy path to add the Multiverse module to existing products without major re-design of the product. The Basic Integration Method replaces the DMX/RDM input circuitry, provides a DMX and RDM stack and appears as a single integrated OEM RDM device. This configuration also allows for seamless DMX wired and wireless operation without any additional hardware to be implemented. This is the recommended integration method because it provides the most benefit to the end user with the lowest implementation cost. The Advanced Integration Method provides all of the features of the other two methods, but enables multiple universes to be processed. This method of integration is required when you need access to more than a single universe, or need to transport alternate start code (ASC) data. 2.1 Features  Supports ANSI E1.11 DMX512-A and E1.20 RDM  Supports unidirectional alternate start codes  Up to 2,560 DMX slots  Non-Interfering RDM  Adaptive frequency hopping modes  Low Latency < 7ms

599x Series www.citytheatrical.com 18 7 OEM Interfaces The module has three interfaces to OEM systems, SPI, I2C and DMX TTL. Not all interfaces are required to be connected to the OEM CPU. In this section, each interface will be described followed by the three implementation examples. 7.1 I2C The I2C bus provides bidirectional data transfer through a 2-wire interface, a serial data line (SDA), and a serial clock line (SCL). An Attention line is included that is active low to notify the OEM CPU that data is available to be read. The SDA and SCL lines each have 2KΩ internal pull-up resistors. Additional pull up resistors may be needed depending on OEM’s circuit board design. Do not apply a 5 volt logic signal to the I2C bus. You can have a maximum of one module on each I2C bus. Other I2C devices are allowed on the same buss, but may impact performance and should be evaluated. The Multiverse I2C chip address is 0x43. The I2C interface can operate up to fast mode (400 Kbps). The I2C interface is the only interface for configuring the module. All configurable parameters are read or written to this interface. Access any to all slot data can be obtained thru this interface. Care should be taken to not attempt to retrieve more slot data than the interface speed can support for the DMX refresh rate currently being transmitted if loss of data is intolerable. For devices that wish to have a single RDM presence for the integrated device, RDM messages addressed to the OEM’s UID will come from this interface. Addressing registers is accomplished by supplying a 2 byte address after the I2C address. The register addresses are defined below in Table 14.

Table 15: I2C Accessible Data Type Comments Slot Data Any slot data from any stream being sent over the wireless/wired link RDM RDM messages that are directed to the OEM CPU Configuration Configuration registers ASC data for a universe is stored in a different stream than the universe that it was received on. See ???? for more information on streams. 7.1.2 I2C Protocol 7.1.2.1 Strings Strings use 2 registers. The first contains the 1-byte length (0-255) of the string while the second contains the string itself. When the length register is read the register address auto-increments to the string address which means if reading continues the string will clock out after the length. Note that the auto-increment behavior only applies from the length address to the string address. Once the string address is read the address remains at the string address and a subsequent read will clock out the string again. 7.1.2.2 Termination and Overrun If reading attempts to continue beyond the length of a register zeros will be clocked out indefinitely. Zero will also provide an automatic termination for strings. If writing continues beyond the length of a register then extra bytes are discarded. If writing is terminated by a Stop condition before the specified number of bytes have been written then the entire operation is discarded. A write may be suspended and re-commenced by a repeat-Start, but this is not a common use-case.

599x Series www.citytheatrical.com 21 7.1.2.3 Repeated Reads The read/write logic is reset by an I2C Stop condition. Following a Stop a repeated read with no register address write will read the same register again, except in special cases where the register address auto-increments (string-length registers and slot array). If a read occurs with no intervening Stop (repeated Start condition) then reading continues from the previous position. 7.1.2.4 Repeated Writes Following a Stop condition, the first two bytes written are always interpreted as a register address. If a write operation begins with a repeated Start condition then it will continue from the previous position. 7.1.2.5 Slot Array Registers 0x4000 through 0x49FF are individual 1 byte registers at consecutive addresses. Address auto-increments on read or write. Slots are readable in both hub and node modes. Slots are only writeable in hub mode. 7.1.2.6 Timing diagrams Figure 9: I2C Specification 7.1.3 I2C Register Descriptions 7.1.3.1 (0x0046) I2C Attention Register Whenever the radio module needs to read/write data from/to the OEM CPU, it will assert the I2C Attention line. The OEM CPU will read this register to determine the attention reason. Reason codes are defined in Table 17. When reading this register, there will be eight bytes returned. The first byte is the reason, followed by 7 bytes of data. Table 16 defines the data bytes returned.

599x Series www.citytheatrical.com 22 After reading the I2C Attention register, a read of the RDM PD register is required to get the message data. If the PD length reported in the I2C Attention register is less 2 bytes or less, the needed data for the RDM command will be included in the attention register and a read of the RDM PD register is not necessary. Table 16: I2C Attention Data Bytes Byte Definition 0 Attention Reason Code 1 Length of data in RDM PD register (0 – 230 bytes) 2-3 RDM PID in network byte order 4-5 RDM Sub-device number in network byte order 6-7 First 2 bytes of PD if length of PD <= 2, else random value Table 17: I2C Attention Reason Codes Code Reason 0x00 Null 0x01 RDM Get message received 0x02 RDM Set message received 0x03 RDM Set Broadcast message received 0x04 Slot Value Change 7.1.3.2 (0x0047) I2C RDM Proxy Traffic Enable 7.1.3.3 (0x0049) I2C RDM Response This write only register is used to send RDM responses back to the radio module. The radio module will generate an ACK_TIMER with a value of 1 in the case where the OEM CPU does not answer the RDM message within the RDM timing requirements. In order to avoid the ACK_TIMER, the OEM CPU needs to have the complete response transferred back to the radio module within 2ms. When the ACK_TIMER expires and the RDM controller tries to retrieve the response and the OEM CPU still has not supplied the response, the radio module will respond with a NACK NR_BUFFER_FULL and consider the message cycle complete. If the RDM controller sends a message other than Get:QUEUED_MESSAGE before or after the ACK_TIMER and the OEM CPU writes a new response to the RDM Response register, the old message is overwritten.

When the I2C Attention register is read and the PD byte is greater than 2, this register must be read to get the RDM messages payload. 7.2 SPI The SPI interface is used for slot data and RDM messages external to the OEM product. The interface has an attention signal to notify the OEM CPU that the interface has data available to be read. This interface is mutually exclusive with the UART interface. If you use the UART for a DMX interface, SPI is disabled. If you enable the SPI interface, the UART is disabled. 7.2.1 SPI Protocol Table 19: Synchronous Serial Interface (SSI) Characteristics PARAMETER NO.

It is capable of proxying a limited number of RDM devices. 7.4 Recommended Configurations The interfaces that are connected to the OEM CPU should fall into one of three setups. These setups are based on what your data needs are and whether you intend to appear as a unified RDM device or not. 7.4.1 Minimal This configuration has the following features:  DMX is not intended to be sent from module  Consumed DMX slots are retrieved via the I2C interface  All configuration operations set via I2C interface
