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.
It is also possible not to use the talk function. In this case, the function of these cards is limited to input and
output control, and the MS-900 Master Station is used for conversation.
