2.5 Installation
Flange-mounted wind direction sensors threaded flange firmly fixed to the lower portion of
the tube flange, the chassis Ø65mm, open Ø6mm four mounting
holes are circumferentially Ø47.1mm using only bolts to securely in the bracket On the whole set
of instruments, to maintain the best level, to ensure the accuracy of wind direction data, flange
connection easy to use, able to withstand greater pressure.
Attention to the installation, the direction of the aviation plug must be consistent with
the north direction, so as to avoid measurement errors.
2.6 Considerations
1. Never disassemble, but can not touch the sensor core, so as to avoid damage to the
product.
2. The device as far away from the interference power, in order to avoid inaccuracies in
the measurement, such as inverter, motor, installation, disassembly must disconnect the power
transmitter into the water cut-off can lead to irreversible changes in the transmitter.
3. Prevention of chemicals, oil, dust and other directly against the sensor, not the
condensation, long-term use in extreme temperatures to prevent thermal shock.

3. Configure the software installation
and use
3.1 Software Selection
Open the data package, select "Debug Software" --- "485 parameter configuration
software" to find Open it.
3.2 parameter settings
①, select the correct COM port ( "My Computer - Properties - Device Manager - Port"
inside view COM port), a figure below lists several different names drive 485 converter.
②, just take a single piece of equipment and power-up, click on the software testing baud
rate, the software will test the current baud rate and device address, the default baud rate
is 4800bit / s, the default address is0x01.
③, the address needs to be modified according to the use and the baud rate, and can query
the current state devices.
④, if the test is unsuccessful, recheck the wiring and equipment 485 driver installation.

4.2 Frame format definition data
Using M odbus - RTU communication protocol, in the following format:
Initial structure ≥ 4 byte time
address code = 1 byte
function code = 1 byte
Data area = N bytes
Error checking = 16-bit CRC
End structure ≥ 4 byte time
Address code: for the address of the transmitter, the communication network is the only
(factory default 0x01).
Function Code: The host command functions such directions, the transmitter has used only
the function code 0x03 (read data register).
Data area: data area is the specific communication data, note data of 16bits endian!
CRC code: two-byte checksum.

11
5.1 device can not connect to a PLC or PC
possible reason:
1) computer has multiple COM ports, port selection is not correct.
2) device address error, or there is a duplicate device address (factory default all 1).
3) The baud rate, parity, data bits, stop bits error.
4) The master polling interval and response wait time is too short, it is required more
than 200ms provided.
5) 485 has turned off, or A, B line reversed.
6) the number of devices or the wiring too long, to be near the power supply,
plus booster 485, while increasing 120 Ω termination resistor.
7) USB drive switch 485 is not installed or damaged.
8) equipment damage.
