After having requested to enter stand-by mode, it takes up to 0.5 seconds for the receiver
to actually enter low-power state. This time is required to unmount the SD memory card
(if applicable) and to stop all software activities.
Waking up from stand-by mode is done in one of the following ways:
1.
by sending one or more characters to the first serial port (COM1) at a baud rate
lower than 4800baud;
2.
by shortly driving pin#8 (nPOWER_TOGGLE) low.
Note that if the receiver has been set in stand-by mode by the command
“
exePowerMode, ScheduledSleep
”, it will wake up automatically after a prescribed
amount of time.

SD Memory Card Usage
The receiver can interface to an external SD memory card through the SD-card pins of the
80-pin connector. The recommended circuit to a 9-pin SD memory card socket is shown
below.
The receiver is compatible with SD cards of up to 32GB. The file system is FAT32.
When powering off the receiver while logging on SD card is ongoing, it can be that the last
seconds of data are lost. To avoid data losses, it is recommended to first unmount the SD
card using the “
exeManageDisk, DSK1, Unmount
” command.
All log files are stored in the directory /ssn/SSRC7 on the card.
