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.

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.

4. SYSTEM DESIGN
Prepare the required equipment according to the procedures below.
Step 1. Determine the required number of LEDs, switches, and interlocking devices.
Step 2. Determine whether or not the VS-900DI's talk function will be used.
If this card function is not used, use the MS-900 Master Station for conversation.
Step 3. Determine the number of VS-910DI cards required based on the result of Step 1 above.
Tip
The VS-910DI Direct Select I/O Card has 32 calling station indication outputs, 32 direct select inputs,
and 32 external device control outputs.
Step 4. Determine the power capacity required, and prepare the power supply.
Be sure to provide sufficient power capacity for external parts such as LEDs, in addition to the current
consumed by each card.
5. INSTALLATION
5.1. Setting the VS-900DI Station Addresses
Settings are required for both the station address and whether or not the talk function will be used. If the talk
function is not used, use the MS-900 for conversation. Perform the following setting using switch SW6.
Note
If the SW6 setting has been changed, turn OFF the unit power, then ON again.
