RoadRunner also accepts any of the digital interface modules available from MUSICAM USA, and can be used over any digital facility that accepts V.35, X.21 or RS422 interfaces, in addition to ISDN.

    9.5 pounds (4.3 kg). Inside the RoadRunner case is a full featured 3-channel monaural audio mixer, an 18-bit A-to-D converter, a multi-algorithm codec, a slot for available plug-in digital interface device (an ISDN terminal adapter is supplied as standard), an auto-dialer, international AC and DC power supplies, and a powerful command processor.

  • Page 15: Digital Interface Module

    A digital interface module is required to use your RoadRunner with a transmission system. Only one DIF module can be installed in the RoadRunner at a time. If you are using a DIF101 or DIF102 module for RS422, X.21 or V.35 interfaces use the appropriate cables, available from MUSICAM USA.

    The RS422 interface can also echo the transmitter clock. If the terminal equipment clocks the encoder data with the echoed clock, the RoadRunner may be located up to 4000 feet (1219 meters) from the terminal equipment without concern for encoder-to-clock skew.

    RoadRunner because of its size. Instead, a smaller DB15 connector is used. In the case of the V.35 interface, the RoadRunner conforms to the electrical specification but requires an adapter cable to convert the DB15 connector to the connector specified in the V.35 specification.

    The TA101 requires country specific ROM chips for use in different countries. Please contact MUSICAM USA, CCS-Europe or your local distributor for information if you plan to take your RoadRunner to a different country.

    When connecting the RoadRunner to external mixers or recording devices, it is easiest to adjust the levels by putting the RoadRunner into loopback <Sys LB><Loopback>. Don’t forget to take the RoadRunner out of loopback when done.

    The first step is, of course, negotiating with the far-end user. Determining what algorithm, bit and sample rates you want to use, and who will make the call. The next step is configuring your RoadRunner, and the last step is connecting.

    Far-End Remote Control With an attached terminal, you can do the following: (1) you can control your RoadRunner, (2) you can control a far-end RoadRunner, and (3) you can control a far-end Prima series codec. Far-end remote control is only possible when both codecs are framed using any MPEG Layer 2 configuration (including MPEGL2, CCSN and CCSO) and when both ends are set to the MUX mode of ancillary data.

    As configured from the factory, each optical input (LL Action) is linked to a corresponding relay on the far-end codec (LL Event) through ‘Links’. Toggling the optical input will toggle the relay on the far-end RoadRunner or Prima series codec. Using Logic Language, you can easily re-define these factory defaults.
