  • Page 4: General Description

    1. GENERAL DESCRIPTION The VS-900DI Direct Select Control Card and VS-910DI Direct Select I/O Card are interface cards that connect to the VS-900 Exchange to enable calling-station indication output, direct select input, and external equipment control output functions. Because these interface cards also have a talk function, by mounting these cards in a control console in combination with a microphone or other devices, the system can be used as a substitute for the MS-900 Master Station.

  • Page 5: Basic Operation

    2.2. Basic Operation The VS-900DI Direct Select Control Card transmits, instead of the MS-900 Master Station, dial signals corresponding to key inputs. Based on information provided by the VS-900 Exchange, the VS-900DI also outputs signals for the calling station indication and external equipment control to the VS-910DI Direct Select I/O Card, which in turn controls LEDs, switches and external equipment.
