Description
Working mode
USR-M100 gateway supports 5 different operation Modes which are TCP Server, TCP Client, and
UDP,HTTP client and websocket. The operation Mode describes the role of the device and the
connection between the device and other remote devices in the network which would like to
communicate with serial device on M100’s COM port.
Maximum socket no.(TCP
server only)
This option specifies the maximum number of remote devices/clients (with maximum of 16 clients) that
can be connected to the serial device on this COM port.
Local port
This option specifies the port number that the TCP/UDP server should listen to. It is also used by the
remote TCP/UDP client to connect to the TCP/UDP server. The default local port is 23. You can enter
different port numbers in this option.
Remoter server addr.
Please specify the IP address of the TCP/UDP server program on the remote host in this field. This should
match the IP settings of the TCP/UDP server program.
Remote port
Please specify the port number of the TCP/UDP server program on the remote host in this field. Once
again, this should match the IP setting of the TCP/UDP server program.
Timeout
reconnection(TCP/UDP
client)
The default is disable. If you want to keep connection continually, you can disable it. Data idle Time is the
time period for which the device waits for data. If the USR-M100 gateway does not receive data during
established idle time(timeout), the USR-M100 gateway will disconnect temporarily. When the data comes
in, it will reconnect automatically. Users do not need to reconnect.
Modbus polling
This option is selected when multiple modbus maters from Ethernet are polling the same serial port.
Each serial port supports up to 16 simultaneous TCP connections allowing hosts to simultaneously
transmit/receive data to/from the same serial port, USR-M100 gateway processes the data in the order
