If you accidentally insert a crimp terminal pin into the wrong socket, youll need to use the supplied pin extractor tool (W/S#850069) to remove terminal pin, and correct your mis- take without having to sacrifice a connector. Place extractor tip (red side) over terminal pin to be removed (figure 5), and press it down- wards motion until tip rests upon Housing. Then pull out the terminal pin from Housing. It should never be necessary to discard a con- nector due to a wiring error.

Installing the audio card - Care must be taken when plugging in the expansion cards 40 pin ribbon connector. Be sure to match the connector sockets to the motherboard header pins. Failure to do so will damage the expansion card, ribbon cable, and/or motherboard. Configuring the software - The ADR-32 software has been pre-configured to automatically recognize a newly installed audio I/O card. You may run the X-Point application to edit the pre-configured I/O names to match your new sources or destinations. Please see the “X-Point Software Setup Guide” for details. !

A Signal Defini- tions form in the supplied X-Point software allows the user to set attributes for the input channels including signal name, type, circuit #, etc. These signal attributes are pre-configured at the factory for stereo operation. Note: While it is possible to split the 8 stereo AES inputs into 16 mono channels, there are still only 8 physical wires, each containing the 2-channel AES formatted data. A dedicated sample rate converter for each input re-clocks the incoming audio data and phase locks it to the systems master sample rate clock. Source sample rates from 16 kHz to 96 kHz are supported. AES Input Interface The balanced digital audio inputs on the SRC-8 card are transformer coupled. AES receivers strip off the received sample rate clock and audio data for further processing by sample rate converters. The balanced interface operates at a nominal peak-to-peak input voltage of +5V with an input impedance of 110 and conforms to the AES-3 1992 electrical specification. Note that Channel Status data is not forwarded. While unbalanced SPDIF formatted input signals may be connected to the HI and LO inputs of an AES input channel (leave the shield floating), it is recommended that a BALUN or other external matching device be inserted to convert the SPDIF impedance to 110 and signal level to at least 1V p-p. page 2 7ADR-32 / Dec 2002 H A R D W A R E Internal Programming Options SPDIF 75 Termination SW1 - SW8 - These slide switches activate 75 termination for SPDIF sources. Default is OFF (110). Slide the corresponding switch 1-8 ON when connecting an SPDIF source. Hook-Ups All user wiring to the SRC-8 card takes place at the female DB-25 I/O connector on the cage rear.
