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.
