3 HARDWARE DESCRIPTION 

3.1  BOARD SETTING: JUMPERS AND CONNECTORS 

 

Figure 3-1 shows the connectors and jumpers available on 73M1903 Demo Boards.  JS1 is the 
main connector for communicating with a host processor or DSP board. The pins of this interface 
connector are configurable by 0 Ohm resistors. R26 through R47 are option-setting resistors. 
Tables 3-2 and 3-3 describe the details of the jumper settings and 0 Ohm resistor population 
options. J5 is a modular connector for phone line connection and J4 is for power connection from 
the main board or an external power supply.
