The following article will guide through connecting and setting up the VS-2480 and a DIF-AT or DIF-AT24.

Setup

1. Turn off all devices.
2. Connect R-BUS 1 or R-BUS 2 connector on the back panel of the VS-2480 to RMDB-2 connector on the back of the DIF-AT using an R-BUS cable.
   Note: You must use a R-BUS or RMBD2 proprietary cable only. Connecting with other cables, such as SCSI connection cables, may cause damage and are not compatible.
3. - If audio will be sent from the VS-2480 to the ADAT Lightpipe device, connect a TOSLINK optical cable from the ADAT OUT of the DIF-AT to the ADAT IN of the external device.
   - If audio will be sent from the external ADAT Lightpipe device to the VS-2480, connect a TOSLINK optical cable from the ADAT OUT of the external device to the ADAT IN of the DIF-AT.
   - If you'll be passing audio in both directions, two TOSLINK optical cables will be needed. Connect the ADAT OUT of the external device to the ADAT IN of the DIF-AT and then connect ADAT IN  of the external device to ADAT OUT of the DIF-AT.
4. Turn on the VS-2480.
5. After the VS-2480 project has completely loaded up, turn on the external ADAT device.
6. On the VS-2480, Press UTILITY.
7. CURSOR to PROJECT and then press ENTER.
8. Use the TIME/VALUE dial to highlight R-BUS 1 or R-BUS 2 in the MASTER CLOCK section--depending on which R-BUS connector is actually connected to the DIF-AT.
9. Press the ENTER button to change the Master Clock from "Internal" to the R-BUS 1 or R-BUS 2. "R-BUS 1 In Lock" or "R-BUS 2 in Lock" will be displayed.

Sending Audio from the VS-2480 to the External ADAT Device

IMPORTANT NOTE: The external ADAT device MUST be setup at the same sample rate as that of the currently loaded VS-2480 project. You can see the sample rate of the VS-2480 project in the PROJECT list (by pressing project). Check the documentation of the external ADAT device for the proper setup procedures.

1. Press the EZ ROUTING button.
2. Press F3 (OUTPUT) to select the output page.
3. Use the CURSOR buttons and TIME/VALUE dial to make the following settings--depending on whether the DIF-AT is connected to R-BUS 1 or R-BUS 2.
   
4. Press the TR 1-16 button or the TR-17-24 button above the red MASTER fader.
   
5. Press the CH EDIT button of the track that you would like to send to R-BUS out to.
   
6. CURSOR to the DIR section on the screen, select the direct out of your choice and then press ENTER to select the direct out that the track will be going to.
7. Repeat these steps for any remaining tracks.
8. Setup your external ADAT device to receive the ADAT signals being input into it. Check the documentation of the external ADAT device for the proper setup procedures.

Sending Audio from the External ADAT Device to the VS-2480

IMPORTANT NOTE: The currently loaded VS-2480 project MUST be setup at the same sample rate of the external ADAT device. You can see the sample rate of the VS-2480 project in the PROJECT list (by pressing project). If the sample rate of the VS-2480 needs to be changed, a new VS-2480 project will need to be create

1. Press the EZ ROUTING button.
2. Press F1 (VIEW) to select the input page.
3. Use the CURSOR buttons and TIME/VALUE dial to connect R-BUS 1's eight inputs or R-BUS 2's eight inputs into INPUT MIXER 17-24.--depending on whether the DIF-AT is connected to R-BUS 1 or R-BUS 2.
   Note: R-BUS 1's eight inputs are already connected by default.
   
4. Press [IN 17-24] next to the MASTER FADER.
   
5. Raise faders 17 through 24.
   
   
   
6. Setup your external ADAT device to send audio to it's ADAT optical output. Check the documentation of the external ADAT device for the proper setup procedures.
