UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Introduction The IRC-28C transmits two channels of audio plus closed captioning data over infrared. Channel A is transmitted at 2.3MHz. Channel B is transmitted at 2.8MHz. Both carriers are frequency modulated. Channel A is normally used to carry the Hearing Impaired audio, while channel B is normally used to carry the Visually Impaired - Narrative audio. 1. Ethernet Connector 2. and 6. Input audio level range switches for channels A & B.

Channel A is modulated on a 2.3MHz FM carrier. Channel B is modulated on a 2.8 MHz FM carrier. Either or both channels are transmitted by the IR panel. Balanced, differential input. One side of each may be grounded for unbalanced sources. Ground at source is recommended. e. Pin 7 & 10: Audio system ground 11. BNC RF Connectors.

There should be: One system manual One IRC-28C Emitter Panel One IRP-20 DC Power Pack One Mounting Bracket composed of 1 ea. IRBS-20 & IRBE-20 Two 10-32 x 5/8 machine screws for attaching the emitter panel to the mounting bracket.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Cinema Processor HI / VI - N Out Initial Audio Configuration and Test It is easier to configure and test the IRC-28C before it is installed. The configuration and test procedures are listed below. 1. Connect the power supply to the IRC-28C. Note the + and - terminal marking near the terminal strip. Connect the positive (red) wire to the positive terminal. 2. Connect the HI audio to the channel A terminals of the IRC-28C.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Closed Caption Configuration The system is configured using a web browser on a laptop computer. Connect the laptop to the IRC-28C using a crossover Ethernet cable. A straight through cable may be used on many laptops, but a crossover will work with all laptops. Set the laptop IP address to 169.254.1.123 with a subnet mask of 255.255.0.0. Open a web browser and go to http://169.254.1.1 . A page similar to that below should appear.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Starting on the left side of the screen, configure the system using these steps: 1. Set the DCS IP address. This is the Digital Cinema Server IP address the IRC-28C will use to get data from the DCS. 2. Set the timeline offset to 0 Edit Units. If desired, this can be changed to make captions earlier or later. A positive number makes captions appear earlier. 3. Set the caption protocol to SMPTE.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. and subnet mask for the IRC-28C. If desired, a netbios hostname can also be set. Since DNS is not used by the IRC-28C, these fields can be left unchanged. 13. Once the network configuration has been entered, press Save IP Config and Reboot. The IRC-28C will reboot at the new IP address. 14. Connect the IRC-28C to your DCS control network. 15. Reconfigure your laptop for the DCS control network and connect it. 16.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Mounting the IRC-28C Attach the supplied mounting bracket to the wall surface and use the supplied screws to attach the bracket to the emitter. Allow free airflow around the emitter and be sure to have at least four inches clearance from all surfaces, preferrably more. The rear panel is used as a heat sink and must be allowed to dissipate heat. The emitter will cover up to 6,500 square feet (77 x 84 feet).
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Installation Using Two UPC-28Cs Two or more IRC-28C panels may be cascaded to provide adequate coverage for a very large auditorium. In such a case, one IRC-28C panel becomes the master source with normal audio input(s), level settings and Ethernet connection. An RF feed from the master panel is carried by a 75 ohm coaxial cable (RG-59/U or similar) to the first slave panel (RF Out of the master drives RF In of the slave).
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Streaming Log The IRC-28C makes a streaming log available on TCP port 10001. You may view this log using telnet, a terminal program such as Tera Term, or by using the PCMan Firefox extension. If the IP address of the IRC-28C is 192.168.1.158, a telnet command to view the streaming log would be “telnet 192.168.1.158 10001”. With the PCMan Firefox extension, it’s possible to just click the “Telnet to port 10001 on this device to see a streaming log.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. Basic DCS Test You can verify whether the DCS supports SMPTE captioning by using a laptop to connect to the Content Synchronization Port. Disconnect the IRC-28C from the network. Set your laptop to the IP address of the IRC-28C. Use Tera Term or telnet to connect to the DCS on port 4170. For example, the command “telnet 192.168.1.189 4170” (assuming the DCS IP address is 192.168.1.

UPC-28C Instruction Manual Ultra Stereo Labs, Inc. In the above RPL fragment, there is a ReelResources element for each reel of the movie. Within each ReelResources element are one or more ReelResource elements. The IRC-28C looks for a ReelResource with ResourceType of ClosedCaption. Note the Language attribute within the ReelResource. Here “en-us” and “es” are shown. If captions are only provided in one language, the Language attribute is optional.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. After clicking on a debug link, the caption text is shown at the top of the screen. Below that is the Program ID of the content currently playing, as reported by the DCS in the Content Synchronization Protocol timeline update message. The FrameNum is the edit unit currently being displayed. This is generated by a clock in the IRC-28C that is synchronized with the DCS using the Content Synchronization Protocol.
UPC-28C Instruction Manual Ultra Stereo Labs, Inc. In the sample screen capture, 0x6487 is binary 0110 0100 1000 0111. This is decoded as: We are connected to the DCS. An announce request has been received from the DCS The lease with the DCS is active. We are not currently fetching an RPL. We are not currently parsing an RPL. We are not currently fetching a timed text (caption) file. We are not currently parsing a timed text file. Stream 0 is assigned (we have data for language 1).
