PM4301APDA

SETTING UP THE PM4301APDA

The PM4301APDA evaluation board can be set up for the various functionality of the SA4301A/SA9105G through jumpers. The

function of each jumper is described in Table 2. The connection of the jumpers corresponds to the markings on the evaluation

board.

Jumper

Description

J1, J2, J3

Mains Voltage Selection: These jumpers are used to select the mains voltage of the system. They are

left open when the mains voltage is 220V and should be closed when 110V mains voltage is used.

J4, J5, J6

RA Selection: These three jumpers are used to set the value of the RA input pin to select the various

pulse output dividers for the SA4301A/SA9105G and to select the enabled channel when the device is

placed in single phase calibration mode. Closing J4 sets RA to VDD, closing J5 sets RA to VSS and

closing J6 sets RA to PH/DIR. Leaving all three jumpers open sets RA to a floating condition. Only one

of these jumpers should be closed at a time.

J7, J8, J9

RB Selection: These three jumpers are used to set the value of the RB input pin to select the various

pulse output dividers. Closing J7 sets RB to VDD, closing J8 sets RB to VSS and closing J9 sets RB to

PH/DIR. Leaving all three jumpers open sets RB to a floating condition. Only one of these jumpers

should be closed at a time.

J10, J11, J12

MS Selection: These three jumpers are used to set the value of the MS input pin to select the mode of

the programmable adder. Closing J10 sets MS to VDD to enable absolute sum mode, closing J11 sets

MS to VSS to enable total sum mode and closing J12 sets MS to PH/DIR to enable import energy only

summing mode. Leaving all three jumpers open sets MS to a floating condition and single phase

calibration mode is enabled. Only one of these jumpers should be closed at a time.

J13

FMS Selection: This jumper is used to set the value of the FMS pin and can be set to “0” to set FMS to

VSS or “1” to set FMS to VDD. This jumper can be left open to set FMS to a floating condition to enable

FAST mode on the SA4301A/SA9105G.

J15, J16, J17, J18

Tamper Enable: These jumpers allow the LED tamper indicator array to be disconnected from the

SA4301A/SA9105G. If all four jumpers are closed the LED array is fully functional.

J20

LED Enable: This jumper can be used to disable the pulse output of the evaluation board. Leaving this

jumper open will disable the PULSE LED as well as the PULSE opto-isolated output (JS6).

J22, J23

Counter Enable: These jumpers can be used to disable and configure the external energy counter that

is connected to the COUNTER output (JS7). Leaving both jumpers open disconnects the counter from

the energy metering device. Closing J22 and setting J23 to “A” configures the COUNTER output to

accommodate a stepper motor counter by connecting the COUNTER terminal to MON and MOP of the

energy metering device. Closing J22 and setting J23 to “B” configures the COUNTER output to

accommodate an impulse counter by connecting the COUNTER terminal to MON of the energy

metering device and VSS.
