Put Serial Ports on
Your LAN
Remotely access anything serial
Much of today’s high-tech equipment ships with a serial
port for programming, monitoring or diagnostics. Put those
serial ports to work for you with B&B’s Ethernet
to Serial Converters, saving you time and trips to the factory
floor.
Guide to Ethernet Serial Server operation
Serial RS-232, RS-422 and RS-485 devices are no longer 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 also allows traditional Windows PC software accessibility
to serial devices anywhere on your LAN or WAN.
Ethernet to Serial Servers feature
three operating modes:
Virtual COM Mode
In Virtual COM mode a driver is installed on the Windows®
PC. This creates a virtual connection between the PC and the
IP address of the Ethernet to Serial Server over the LAN or
WAN. The new COM port shows up in the Windows Device Manager.
Windows applications use standard Windows API calls to communicate
through this virtual connection with no changes to the software.
After connection, the LAN is transparent to the program
and serial device. Applications work just as if the serial
device is connected directly to a physical COM port on the
PC.
Direct IP Mode
Direct IP connections allow applications using TCP/IP or UDP/IP
socket programs to communicate directly with the serial ports
on the Ethernet Serial Server. In this type of application
the serial server is configured as a TCP or UDP server. The
socket program running on the PC establishes a communication
connection with the serial server’s IP address. The
data is sent directly to and from the serial port on the server.
This is the connection scheme that we recommend if you’re
writing your own application.
Paired Mode
Paired Mode is also called serial tunneling. In this mode
any two serial devices that can communicate with a serial
cable can communicate using two Ethernet Serial Servers and
a LAN. The serial servers handle the network-side communications
automatically. In this mode one serial server is configured
as a client and the other as a server and each is programmed
with the mating device’s IP address. This mode of operation
creates a serial connection between any two serial devices
with the only restriction on cable length being the size of
your LAN or WAN.
