Communication Modes

ES1AWB 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 ES1AWB 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 ES1AWB. 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 ES1AWB. When
using UDP protocol the ES1AWB can be configured to broadcast data to
and receive data from multiple IP addresses.

Virtual COM Port

Virtual COM Port mode (also called COM port redirection) allows you to
map a COM port on your PC to the serial port on your ES1AWB. Using the
RealPort software (included with the ES1AWB) you create virtual COM
ports on your PC. When your application sends data to this port, RealPort
redirects the data across the network to serial device connected to the
ES1AWB serial port. The network is transparent to the user application and
the serial device connected to the ES1AWB.
