DR301

DR301 is a tiny size RS232 to Ethernet converter, which can realize the bidirectional transparent transmission between RS232 and Ethernet.

• RS232 Port: Terminal Type
• Industrial-grade, DIN-Rail mounting
• Modbus RTU to Modbus TCP

Serial to Ethernet converter DR301 monitors the set port and waits
for a TCP client connection. Data from the serial device will transmit
to all successfully-connected via serial to Ethernet converter.

DR301 only communicates with the target interface of the target IP,
thus to assure the accuracy of data transmission.

DR301 can transmit the data automatically to the last time transferred
device after receiving the data, which is suitable for multi-network
devices that need to communicate with the DR301.

DR301 supports the function of transmitting the serial data to the
specified server in the form of HTTPD (GET/POST).

Support Modbus gateway

More functions

Virtual serial software

Solve the problem of PC software
as a serial port can not communicate
with networking device.

Network Heartbeat Packet

Serial server maintains the normal
connection with the server by sending
heartbeat packet regularly.

Identity Heartbeat Packet

When 301 works as TCP Client, it can send identity packet
packet to TCP server which can be identification.
Identity packet can be IMEI code, ICCID code
and user editable identity packet.

USRIOT Cloud

DR301 can realize the bidirectional transparent
transmission between the server and terminal device
through USRIOT Cloud quickly.
