2. Working mode of HAC-ADSB:(Tag)
1).The ex-factory state of HAC-ADSB is sleeping state, it does not send wireless signal,
it is low power-consumption. It is convenient for transportation and stock.
2). Press the ‘Start’ button for 3s, the tag starts and enters into working mode, it will
send ID information every 4s, and the working time is less than 1.5ms, the rest time is
sleeping. The red LED will flicker once for every data transmission. The sending
interval can be set by users. The temperature sampling period is 2mins per time.
3) During the working time or after power on, press ‘Start’ button for 3s AGAIN, the tag
will enter into setting mode. Users can change the ID, sending interval, RV1, RV2. After
finishing setting, it will exit the setting mode immediately. If there is no setting within
30s, it will exit the setting mode automatically.

4. HAC-ADM-MU can use USB port to charge. On the same time, it will transfer USB port to
a virtual serial port. You need to install the driver of USB to virtual serial port. The driver
software is: PL2303_Prolific_DriverInstaller_v130.exe.You can refer to
PL2303_Prolific_DriverInstaller_v130_releasenote.txt to know more about how to install the
USB to serial port driver.

After the installation, the device manager of PC will add a new serial port, and then you can
use ScomAssistant to receive the information send from the RFID. (please install the
Terminal.exe for ScomAssistant). Serial port: 38400bps, 8N1
III. Serial Data Protocol
Serial port output:
The serial port of HAC-ADM-MU (The receiver) outputs the information of HAC-ADSB
(the tag) with 38400bps & 8N1 data format. The protocol of information is shown as
following (Hex):
24 UID1 UID0 ID3 ID2 ID1 ID0 S V RV1 RV2 TMP1 TMP2 TS RSSI CS
24: Frame head
UID1 UID0: Category ID number
ID3 ID2 ID1 ID0:ID number of HAC-ADSB
S:Reservation
V:Voltage of battery
VCC= (BV/256)*3.45,if the battery is lower than 2.5V, it is under-voltage.
RV1: Setting word by Users, default value: 00
RV2: Setting word by Users, default value: 00
TMP1: High-byte for temperature data
TMP2: Low-byte for temperature data
Temperature = ((TMP1<<8|TMP2)-500)/10
TS: Serial number of transmitting
RSSI: The strength of transmitting signal, dBm with symbol
CS: The low byte of the previous data check sum
