Hydrological Services Pty Ltd Introduction The Hydrological Services BlueComms BC1 has been designed using surface mount technology to provide a small, robust, Bluetooth interface for retrieving data from the MiniLog data logger in the field using a PDA. The unit is powered by 2 x AA alkaline batteries.
Hydrological Services Pty Ltd Product Overview Overview The Hydrological Services BlueComms Communicator is a Bluetooth to RS232 interface with several unique features. • DB9 Male connector for direct connection to the HS MiniLog. • Self powered by 2 x AA alkaline batteries.
• Pins 7 and 8 are linked together inside the ML1. 2. When the BC1 is directly connected to an ML1, sufficient power is extracted on pin 4 to power the ML1 – which prevents power drain from the internal ML1 lithium battery while communications is in progress.
MiniLog must also be setup for communications at 9600 baud. Batteries The BlueComms BC1 operates on 2 x AA alkaline batteries. To change the batteries : • Remove the screw securing the battery cover. • Slide open the battery cover.
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.
Hydrological Services Pty Ltd Operation Connection to a PDA Once the BlueComms Communicator is plugged into the MiniLog, the operator must connect to it from their PDA via a Bluetooth wireless connection. The following procedure is indicative only, and depends upon the PDA being used.
