Communication Protocol 5.1 Data Format 5.1.1 Format There are two data types Data 1, Data 2. The duration time for each data is 610us Data 1: The duration time of High Level is 400us, The duration time of Low Level is 210us. Data 2: The duration time of High Level is 210us, The duration time of Low Level is 400us. 5.1.2 Preamble Format The preamble is 1 byte. There are 8 bits in the preamble. It is made up of 4 high levels (610us) and 4 low levels (610us) as below figure. It is transmitted from high level.

Product Operation 7.1 Receiver 7.1.1 Key Function 7.1.1.1 There is one slide switch to select C/F unit. 7.1.1.2 There is one slide switch to select ID A, B, C. 7.1.2 When Power on or reset the LCD will full display for 3 seconds, the unit start to work. 7.1.3 The unit will detect the temperature and humidity every 30s. 7.1.4 Indoor Humidity Calculation and Display 7.1.5 Indoor Temperature Display 7.1.6 The outdoor temperature and humidity will be displayed when the signal is picked up, and the High/Low temperature is displayed at the same time. 7.1.7 Display of high and low outdoor temperatures is to be a rolling 24-48 hour value as follows:
7.1.8 Trend lines (increasing decreasing steady) 7.1.9 RF433 Reception When power on the receiver, the unit will turn on the RF module to looking for the RF signal, the RF433 reception bars cycles (i.e. one bar, two bars, three bars.one bar, two bars etc.) This continues until the unit receives a valid signal or for maximum 6 minutes if no signal is captured. 7.2 Transmitter (FCC ID: RNERF100XTX) 7.2.1 Key Function 7.2.1.1 A C/F button (search button) is added inside the transmitter. 7.2.1.2 A slide switch with A, B, C position is to select A, B, C channel. The factory default setting is A. 7.2.4 The unit will detect the temperature and humidity every 16s. 7.2.5 Outdoor Humidity Calculation and display in the receiver 7.2.6 Outdoor Temperature Display in the receiver Copyright 2006 Primex of Companies - All rights reserved Page 6 of 6 This device complies with part 15of the FCC Rules and RSS-210 of IC rules.
