Considerations for Remote Sense only PRM
This board is designed to accomodate dierent types of PRMs. Therefore, certain
circuitry on the board is not populated and there are additional considerations for using
Remote Sense only PRMs.
The Remote Sense PRM Evaluation Board does not operate in default switch S10 setting
which has all switches in the OFF position. Switch at position 1 must remain in the OFF
position. Putting switch at position 1 in the ON position could short the TM pin which
would cause damage. Switch at position 6 must remain in the OFF position as well.
Please see appropriate section for switch setting and mode of operation.
The silkscreen may not match the pin names for Remote Sense PRM. Following table
maps pin names of the Remote Sense PRM to silkscreen and standard PRM.
