Reset Button
A reset button is located between the clock battery and the first P-SCM slot on the main circuit board
(partly hidden under the D-cell battery case).
Should it become necessary to reset the SymphoniePRO logger, carefully place the NRG screwdriver
(provided) or other long, thin tool in the upper corner just to the left of the “Channel 20” P-SCM slot,
and slide down to press the button. Hold until it beeps.
When the reset button is pushed, the logger will beep and reset the logger’s microprocessor, record a
reset event, and resume sampling data for the current file.
Resetting the logger may cause the data from the current statistical interval to be lost (depending on
how long since data was last written to memory).
The logger logs a reset event into the event log and
continues adding data to the same file that was in progress before the reset.
Collected data already written to memory and all logger configuration settings will be retained.
Note that a reset can also be initiated by the built-in watchdog in response to an ESD (electrostatic discharge)
event. When an iPack is connected to a logger with no D-cells, this will also initiate a reset. The iPack provides
auxiliary power to the logger and therefore powers it up in the absence of D-cells.
SD Card Slot
The SD card is inserted vertically in the SD card slot with the beveled front corner down. Care should be taken
when inserting and removing the SD card – do not force the SD into the slot. Qualified, industrial-rated SD cards
(512 MB or 2 GB) are available from NRG Systems.
Caution
Problems with SD cards not supplied by NRG Systems are not covered by warranty.
Wiring Panel Options (16-Channel & 26-Channel)
SymphoniePRO supports two different wiring panels: A 16-channel version and a 26-channel version. The table
below shows which logger channels are available for each wiring panel, and the SymphoniePRO software has a
drop-down selector for choosing a wiring panel which makes configuration easy.
