PES1A and PESV1A Mini PoE (Power over Ethernet) Ethernet to RS232 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.
Introduction
• 10/100 Mbps auto-detecting operation
• IEEE 802.3af (Power over Ethernet) compatible
• Web Configuration and Management user interface
• Email event notification
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.
Figure 1. PES1A Mini POE Ethernet to RS-232 Converter
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.

Paired Mode (also called Serial Tunneling or Serial Bridge mode) allows
serial devices connected to two PES1A/PESV1A converters to communicate
across a network. The two PES1A/PESV1A converters automatically
connect to each other.
In Paired Mode the heartbeat featu re ensures reliable communications by
restoring the connection if communications are temporarily lost at either end
due to loss of power or Ethernet connection.
Other Communications Modes
PES1A/PESV1A Converters also feature the following communications
profiles:
Terminal Mode allows you to connect a PC running terminal software to the
PES1A/PESV1A serial port and communicate with the PES1A/PESV1A via
a command line interface.
Modem Emulation Mode allows you to configure the serial port to operate
as if it is a modem. For legacy applications where a serial device is set up to
communicate through a modem, the serial device can now be connected to
the PES1A/PESV1A and communication occurs over the network. The
PES1A/PESV1A emu lates modem respons es to and from the serial device.
In Console Management Mode the PE S1A/PESV1A can be co nfigured for
connection to the management port typically found on network devices such
as routers, switches and servers. This allows remote management of the
network device. Communication can be accomplished using telnet to a
specific port in the converter.
Custom Mode allows you to custom configure the PES1A/PESV1A serial
port and is used if your application does not fit into any other predefined
modes.

Link Integrity LED (Yellow)
When the yellow LED located on the Ethernet jack is illuminated it indicates
that a connection (link integrity) has been established between the converter
and a node on the network.

The Ethernet Port connector is a standard RJ-45 receptacle that allows the
serial server to be connected to an Ethernet network. It also carries Power
over Ethernet (PoE) based on t he IEEE 802.3af standard.
On the PES1A/ PESV1A two indicator LEDs are built into the RJ-45
connector.
Serial Port Connector
The Serial Port Connector is a DB-9 male connector (configured as a DTE)
supporting RS-232 serial communications including TD, RD, TRS, CTS,
DTR, DCD, DSR and GND signal lines. Use a standard serial cable if
connecting to a DCE; use a null modem (crossover) cable if connecting to a
DTE.
Refer to Appendices D, E and F for connection pin-outs.
Power Connector
Power is supplied to the PES1A/PESV1A by PoE (Power over Ethernet) via
the RJ-45 Ethernet receptacle. Power over Ethernet may be delivered via unused pairs in the CAT-5 cable, or via a simplexed power technique. Both
options are supported by the PES1A and PESV1A. PoE power consumption
for the PES1A and PESV1A are rated Class 3.
Refer to Appendix E for Ethernet connection pin-outs and additional information
on PoE.
Connecting the Hardware
Typically, the PES1A/PESV1A is connected to a network via a hub, switch
or router using standard CAT-5 cable. Power must be supplied to the
converter via the CAT-5 cable using Power over Ethernet. Configuration is
accomplished over the network, or via a direct connection (see below) using
the Web Configuration and Management Interface
Power over Ethernet (PoE)
Power is supplied to your PES1A/PESV1A from PoE power source
equipment (PSE), which must be installed within 100 meters of the
converter. PSEs may be endspan or midspan devices. Endspan PSE devices
may be switches or hubs with integrated PoE capability. Midspan PSE
devices are dedicated, inline devices that are installed between your network
switch and the PES1A/PESV1A.

Output Power Connector (PESV1A only)
The output power connector (on the PESV1A only) is a two position
removable termin al block that provides a DC pow er supply voltage output
(derived from the PoE input power) in three selectable ranges: 5 VDC, 9
VDC and 12 VDC. Maximum output power is 4 watts.

Your PES1A/PESV1A converter typi cally is configured over the network
connection using standard browser software. It also could be connected
directly to a PC network adapter. To do so an Ethernet crossover cable is
required. Also, a midspan power source is required to provide power to the
PES1A/PESV1A.
