Communication Modes
ESR901WB Wireless Serial Servers allow you to connect serial devices
over a wireless network. The connection can be configured in several modes.
Direct IP
Direct IP Mode allows applications using TCP/IP or UDP/IP socket
programs to communicate with the asynchronous serial ports on the serial
server. In this mode the ESR901WB is configured as a TCP or UDP server.
The socket program running on the PC establishes a communication
connection. The data is sent directly to and from the serial port on the server.
• TCP Server Mode allows network devices to initiate a TCP connection
to the serial device connected to the serial port on the ESR901WB. This
is also referred to as reverse telnet.
• UDP Server Mode allows network devices to initiate a UDP connection
to the serial device attached to the serial port of the ESR901WB. When
using UDP protocol the ESR901WB can be configured to broadcast data
to and receive data from multiple IP addresses.
