FLAGS (LEDS)
Tx/Rx flags
Status / USB flags
They signal transmission and reception of data by the RS485/Modbus interface, no matter if it
is configured to operate in master or slave mode.
When connecting the equipment, both leds flash two times and remain extinguished until all
the initialization has been completed.
The Status flag remains ON in normal conditions. When it is logging, the same will have to
flash two times for each 3 seconds. In error cases, this led will be flashing 3 times in each 8
seconds.
In the error cases, please check if the clock of the FieldLogger has the correct date and
time. If they are wrong, probably the battery of the clock has run low and needs to be
replaced. If it is OK, try rebooting the machine by turning off its power supply and restarting it
after 10 seconds. If the led insists on the error indication, there may be something wrong with
your FieldLogger.
The USB flag remains ON only while a cable is connected in the USB device or while the
USB flash drive is plugged into the USB host interface. The following exceptions are:
Download errors via USB flash drive: flash drive with insufficient writing space,
inability to write in the flash drive (write protected) or flash drive not compatible
(sector different from 512 bytes, for example), the USB led flashes while the error
condition remains (typically, until the flash drive has been removed). Check the "USB
Interface" section in the chapter "FieldLogger Operation" for more details.
At the end of the download, if everything is correct, the USB flag remains ON until the
flash drive has been removed from the equipment.
