Back-To-Back Operation:
The W681XXXDK evaluation systems can be connected back to back using the 20x2
header (J11) .The cable should be maximum 2-3 inches in length. It makes all necessary
electrical connections, allowing a full “analog-to-analog, “handset-to-handset” path to be
established.
For back- to-back operation the jumper setting are set to ON position as follows for
(W681XXXDK #1 Master board) unit. J1 (2.048 MHz), J2B, J5 (side tone), J9B, J6,
J10A, J7A (for input).J12B, J13, J15B, J14, J16A, J19A and J20. The W681XXXDK #1
acts as the system master, providing BCLK and FSYNC to W681XXXDK #2. The
jumper setting for board #2 is as follows. J1 (2.048 MHz), J2B, J5, J9B, J6, J10A J12B,
J13, J15B and J16A.
The following DIP-switches are set as for back-to-back -mode
Note: Do not connect the power supply to the second board. It will be bussed to the
second board through the 2x20 cable. Make sure the cable is connected as shown
