BOARD SETUP 3.1 Power Supplies: 1) Verify that all power supplies are off before making connections. 2) Connect a +3.3 V DC power supply to the VD+/VA+ (J6) binding post and place jumper J8 in the ADJUST position. This connection may be omitted by setting J8 to the REG posi- tion. VD+/VA+ will be derived from the on- board +3.3V regulator. 3) Connect a +3.3 V to +5.0 V DC power supply to the VL+ (J5) binding post and place jumper J7 in the ADJUST position. This connection may be omitted by setting J7 to the +5 V posi- tion. VL+ will be derived from the +5 V bind- ing post. 4) Connect a +5.0 V DC power supply to the +5 V (J3) binding post. 5) Connect the common ground of the power sup- plies to the GND (J4) binding post. 6) Apply power to the board. D9 should illumi- nate indicating power is applied to VD+/VA+. 3.2 Hardware Mode Settings: 1) Place switch S1-H/S in the OPEN position. 2) Place switches S3-INPUT, S3-8416_PCM, S3- NVSEL, S3-RXSEL1, S3-RXSEL0, S3- TXSEL1, S3-TXSEL0, S1-M/S, S1-SFMT1, S1-SFMT0, S4-8406_PCM, S4-TCBLD, S4- CEN to the appropriate positions. 3) Press and release the RESET switch S3. The board should now be setup for use in Hardware Mode. 3.3 Software Mode Settings: 1) Place switch S1-H/S in the CLOSED position. 2) Place switches S1-M/S, S3-INPUT, S3- 8416_PCM, and S4-8406_PCM to the appro- priate positions. All other switch setting do not effect Software Mode operation. 3) Press and release the RESET switch S2. The board should now be setup for use in Software mode. 4) Connect a DB-25 parallel port cable from the PC’s parallel port to J1 on the CDB8416. 3.3.1 Installing the Software: 1) Create a directory called CDB8416 anywhere on your system. 2) Copy CDB8416.exe from the included CD into this directory. 3) Run port95nt.exe from the CD. After running the program the system will need to be restart- ed. 4) If desired, create a shortcut to CDB8416.exe on your desktop. You should now be able to run CDB8416.exe. 5) Double-click on CDB8416.exe or its shortcut. 6) Click on the button on the lower right labeled “Advanced”. 7) Select the LPT port you are using to connect to the CDB8416. 8) Shut down the application, reset the board, and then restart the application. 3.3.2 Verifying Board Operation: 1) In the “CS8416 AES Receiver Controls” win- dow, select the check box “Enable Internal Clocks” (enables the RUN bit in the Clock Control register). 2) In the “CS8406 AES Transmitter Controls” window, select the check box “Enable Clocks” (enables the RUN bit in the Clock Control reg- ister). 3) In the “CS8416 AES Receiver Controls” win- dow, select the check box “Generate SCLK/LRCK”. Make sure that switch S1-M/S is in the OPEN position. |
