Table 6 below lists the description of J_SENSE1 and J_SENSE2 jumpers [5], as well as their positions and the

position of pin 1.

In order to convert the IS current into a voltage, J_SENSE2 [3] needs to be closed. In case of using a different

sense resistor, either replace RIS or use an external resistor. Therefore, remove J_SENSE2 [3] and close JSENSE

[1] to enable a direct path from the IS pin of the device to the banana connector. All jumpers are open by

default.

Description

J_SENSE1 [1]

It connects the IS pin of the device directly to the banana connector of the MB and

disables the on-board filter of the IS

J_SENSE1 [2]

It connects the IS pin of the device after the on-board filter to the banana connector of

the MB

J_SENSE2 [3]

It connects the IS pin of the device to the 1.2 kΩ sense resistor RIS and to the μIO

connectors
