PES1A and PESV1A Mini PoE (Power over Ethernet) Ethernet to RS-
232 Converters provide simple and cost-effective solutions for connecting
RS-232 devices to Ethernet networks. PES1A and PESV1A converters make
it easy to connect serial printers, copiers, building automation, retail, point of
sale, warehousing and banking equipment directly into Ethernet networks.
Both models feature Power over Ethernet (PoE) operation and the PESV1A
provides a switch selectable voltage output to power external devices.
PES1A and PESV1A converters support virtual COM port, console
management, TCP and UDP socket, serial bridge, terminal, modem
emulation and custom connections. Network addresses can be obtained
dynamically or manually. Simple Network Management Protocol (SNMP) is
supported. Configuration is accomplished through a web-based user
interface.

Communication Modes
PES1A/PESV1A Ethernet to RS-232 converters allow you to connect
serial devices over a LAN or WAN. Serial devices no longer are limited to a
physical connection to the PC COM port. They can be installed anywhere on
the LAN using TCP/IP or UDP/IP communications. This allows traditional
Windows PC software access to serial devices anywhere on the LAN/WAN
network.
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 PES1A/PESV1A 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 PES1A/PESV1A. 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 PES1A/PESV1A. When
using UDP protocol the PES1A/PESV1A can be configured to broadcast data
to and receive data from multiple IP addresses.
Virtual COM Port
Virtual COM Port mode (also called RealPort, or com port redirection)
allows you to map a COM port on your PC to the serial port on your
PES1A/PESV1A. Using the RealPort software (included with the
PES1A/PESV1A) 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 PES1A/PESV1A serial port. The
network is transparent to the user application and the serial device connected
to the PES1A/PESV1A.
