Installation and wiring
Do not connect the transmitter to a voltage above 24 VDC place.
Refer to the product appearance and dimension drawings for installation equipment in Figure 1.
Install the transmitter in a position where it needs to be detected, and should be kept away from the heating element or the source of steam to prevent direct sunlight. 
When wiring the circuit, connect the wires to the terminals to ensure that the wiring is correct and firm.

Interface description:
From right to left, numbered as 1-7 in sequence, defined as follows:
1、+12V； 2、GND； 3、RS485A； 4、RS485B；5、I1/V1；6、I2/V2；7、TCP/IP
Communication Agreement Section:
use MODBUS The agreement RTU Way, in RTU In mode, use RTU In mode, message sending must start at least 3.5 character pause intervals.When the first domain (Address Domain ) Received, each device decodes to determine whether it is sent to its own.After the last character transmission, a pause of at least 3.5 characters time calibrates the end of the message.A new message can be stopped here and started.The entire message frame must be transmitted as a continuous stream.If there is a pause of more than 3.5 characters before the message frame is completed, the receiving device refreshes the incomplete message and assumes that the next byte is the address field of a new message.
1 、 Hardware adoption RS485 ， Master-slave half-duplex communication, host call slave address, slave reply mode communication.
2 、 Data frame format: 1 start bit, 8 data bits, 1 stop bit, no check bit.
3 、 Baud rate: 9600 bps。
4 、 Message frames include: address field, function code field, data field, CRC16 Detection domain.
5 、 This device supports hexadecimal 03 H 、06H Function code (That is, decimal 03 and 06 function codes ) 。Of which 03 H Used to read the device stack, 06 H Used to modify the device stack.

Notes on using:
(1) RS485 Communication cables need to be shielded twisted pair cables, and if necessary, 2 250 ΩTerminal matching resistor.
(2) The use environment should be free of conductive dust, corrosion-free metals and gases that destroy insulation, and avoid direct light and rain.
(3) More than 90% for a long time RH Working in a high humidity environment will cause drift.
(4) Avoid placing components in salt spray, acidic or oxidized gases (Sulfur dioxide, hydrochloric acid, etc. ) In the environment.
