DBI-TX2 User Manual Issue US1 Page 4/11 1. Description 1.1. General • The DBI-TX2 is a wire less transmitter monitoring free hot air balloon envelope top radiation temperature. It transmits data to the DBI-002 flight instrument where temperature is displayed. • The unit consists of a sturdy aluminum tube enclosure attached by a velcro strap to the basket overhead frame. • The unit is power supplied with a replaceable long life lithium battery. Battery replacement interval is typically four years. • Power on/off is controlled automatic by the difference of device (ambient) and radiation (envelope fabric) temperatures. No operator action is required. • Each unit has a unique serial code that is matched with the receiver DBI-002. DBI-002 data reception is qualified by serial code and comprehensive transmission error detection. • Short duty cycle and low RF power data transmission enables interference free operation and multiple units to operate in close proximity. • Conforms to FCC part 15.249 • FCC approval identification: TDJGC132926

DBI-TX2 User Manual Issue US1 Page 8/11 3. Installation 3.1. Safety Always consult corresponding envelope flight manual for safe attachment. 3.2. Attachment The DBI-TX2 attaches on one overhead frame rod. The IR lens aperture shall point straight up to the top centre of the envelope on a free line of sight.
DBI-TX2 User Manual Issue US1 Page 9/11 4. Operation 4.1. DBI-TX2 identification code Transmitter identification code is marked on the box placard. 4.2. DBITX2 identification code programming Program the DBI-TX2 identification code to the DBI-002 flight instrument by using the DBI-002 PC application software. Refer to “DBI-002 User Manual”. 4.3. Power On / Off The power on / off is automatic: • The DBI-TX2 will start transmission when a temperature difference between the ambient and the radiation temperature is greater than 10 °F. • The DBI-TX2 will stop transmit after 5 minutes when a temperature difference between the ambient and the radiation temperature is greater than 10 °F. • For permanent power off, remove internal battery coin cell. See “5.2 Battery replacement”.
DBI-TX2 User Manual Issue US1 Page 10/11 5. Maintenance 5.1. Battery (Lithium cell) replacement • During normal operation, the internal battery will last for typical 2 years. Recommended replace interval is 1 years. • Replace battery if DBI-TX2 does not operate properly. Unmount the battery cap by pulling it from the tube. Replace the coin cell: • Replace type is “CR2450”. • Positive terminal facing up. • Inspect for clean battery holder metal surface. Clean with soft cloth if dirty. Mount the battery cap by pushing it into the tube.
