USING THE SA9607P IC

The EEPROM on the SA9607AP module may be programmed in circuit with the use of a PC and a IIC interface module. The

interface module is available from SAMES and includes a IIC interface, a 7 way connector cable as well as all the components

needed to convert the module to a trim pot less meter. Figure 2 show how to connect the metering module, interface module as well

as the PC.

To use the PM9607AP module with a SA9607P integrated

circuit the following components need to be changed:

n Insert the EEPROM from socket U3.

n Replace termination resistors R16 and R7 with 3.6W

resistor.*

n Remove Channel 2 trim-pot P1.*

n Remove P2 trim-pot. Short-circuit the trim-pot footprint.*

n Replace resistor R17 with a 24K resistor.*

n Remove jumpers J5, J6 and J7.

n Resistor R22 must be fitted if EEPROM will be

programmed in circuit.

* Component change is only require if the module should not

contain any trim-pots.
