Unpacking Unpack each MUX-8258 you received from the shipping container and ensure that all items are included. If any items are missing or damaged, contact your sales representative or Ross Video directly.
DFR-8321 series frame — The 8320AR-034 Full Rear Module (R2C-8258) is required. Installing a Rear Module If the Rear Module is already installed, proceed to the section “Installing the MUX-8258” on page 2-4. Use the following procedure to install a Rear Module in your DFR-8300 series frame: 1.
Installing the MUX-8258 This section outlines how to install the MUX-8258 in a DFR-8300 series frame. If the MUX-8258 is to be installed in any compatible frame other than a Ross Video product, refer to the frame manufacturer’s manual for specific instructions.
DFR-8300 series frames. Connect the input and output cables according to the following sections. MUX-8258-A Cabling Overview The MUX-8258-A accommodates eight synchronous AES audio input streams at 48kHz or any asynchronous AES streams from 32kHz to 96kHz with SRC enabled. Note that SRC should only be used with Pulse Code Modulation (PCM) digital audio and not any form of compressed signal, such as Dolby®.
Figure 2.3 Cable Connections for the MUX-8258-4C MUX-8258-8C Cabling Overview In the DFR-8321 series frames, the MUX-8258 is used with the following Rear Modules: • 8310AR-034 Rear Module (R1C-8258) — Each card occupies one slot and provides one SDI input, one SDI output, and eight analog inputs. (Figure 2.4) •...
Each connector has locations for the positive, negative, and grounded wires of a balanced analog audio cable. Use the following procedure to wire the analog audio for the MUX-8258-C: 1. Insert an analog audio wire to the designated polarity slot on the connector of the rear module.
Use the following procedure to upload software to the MUX-8258: 1. Contact Ross Technical Support for the latest software version file. 2. In DashBoard, display the Device tab of the MUX-8258 by double-clicking its status indicator in the Basic Tree View.
