BOARD FLOORPLAN
Figure 1
shows the board layout for the DS2149DK. The DS2149 PLCC socket is in the center of the board. The
line-side bantam connectors for the Tx and Rx differential pairs and transformers are at the bottom of the board,
while the system connector and configuration jumpers are at the top. The LEDs for INT, INLOOP, and RCL/QPD
are in the center of the board, right above the DS2149 socket. The power-supply connectors and power indicator
LED are in the upper left corner of the board, while the DB9 serial connector is the upper left. A T1 oscillator sits to
the left of the DS2149 socket below a switch for changing the voltage to the DS2149 socket from 5V to 3.3V.
Please refer to the general locations on the board when this document references specific items on the DS2149DK.
