2.Two main and one slave 485 server gateway isolator (ATM)

a.Functional features: Implement a responsive 485 server function between two hosts and one slave, supporting the MODBUS RTU protocol.

b.Serial port characteristics: Supports baud rates of 1200, 2400, 4800, 9600, 19200, 38400, and 57600bps; Support parity check; 1 or 2 stop bits, etc.

c.The waiting time parameter for the slave is optional.

d.The host delay sending time is optional.

e.Master and slave port hardware: RS485.

f.Modify parameters through the serial debugging assistant.

g.Application: Industrial fieldbus uses two 485 hosts to simultaneously read 485 slave network devices, suitable for communication between MODBUS RTU devices. Supporting multiple devices in series and cascading applications, it can serve as a relay device for long-distance transmission of 485 communication.

3.485 to analog gateway isolator

a.Functional features: Data is provided by the 485 port, and the gateway converts the data into a linear 4-20mA analog output. Supports MODBUS RTU protocol.

b.Serial port characteristics: Supports baud rates of 1200, 2400, 4800, 9600, 19200, 38400, and 57600bps.

c.The accuracy of analog current output is 0.1%.

d.Support data types: 2-byte integer or 4-byte floating-point number, with adjustable data size direction.

e.There is a dedicated configuration tool software to modify parameters.

f.Host port hardware: RS485. The slave hardware outputs analog signals of 4-20mA.

g.Application : The gateway device receives 485 data in MODBUS RTU protocol format, parses the data, and linearly converts it into analog 4-20mA current output, which is sent to the DCS device.
