Hydrological Services Pty Ltd
3.4 LED
Indicator
The LED Indicator serves 4 functions :
•
Low battery indicator
– when the BC1 is first plugged in, the battery voltage is
checked, and if it falls consistently below 2.8V, the LED will flash once every 2
seconds. Even with a low battery, the BC1 will connect and continue to operate for as
long as possible. (It is however advisable to change the batteries.)
•
Searching
– The BC1 is searching (or waiting) for a Bluetooth connection. During
this time the LED flashes once every 0.5 second.
•
Connected
– When a valid Bluetooth connection has been established, the LED will
turn on steady.
•
System Fault
– If the Bluetooth module has lost its initialisation, the LED will flash
twice quickly every two seconds. If this condition is ever experienced, the BC1 should
be returned to Hydrological Services for reprogramming.
3.5 Connection
Simply plug the BlueComms Communicator into the MiniLog. The red LED will start
flashing, indicating it is searching (or waiting) for a Bluetooth connection.
If physical space does not permit the BlueComms to be plugged into the MiniLog, then use a
DB9 male to DB9 female cable (1 to 1). This is the same cable that is used to provide
communications between the MiniLog and a PC.
