Functional Description
Ethernet enable any serial device using
B&B’s Vlinx Serial Server technology and put your serial ports to
work for you. Imagine the ability to communicate with every piece of equipment from any networked PC.
Eliminate site visits just to find a need to make a minor configuration change. Reduce service calls and
increase productivity by knowing what your equipment is doing before you get a trouble-report. Spend more
tim
e doing the work you’re paid to do instead of chasing down nuisance problems with remotely located
equipment.
Much of today’s high-tech equipment ships with a serial port for programming, monitoring or diagnostics.
80% of these serial ports are left unconnected, often because a person travels to the port to make the
connection or a permanent PC is not desirable. With B&B’s Vlinx Serial Servers, you can put all of those
ports to work for you.
Simply connect the Vlinx server to the equipment’s serial port, and connect the Vlinx
Ethernet port to your LAN. Your equipment is now online. It will appear as a local COM port on any
networked PC running our Virtual Serial Port software. No software customization required, just run the
appropriate software for your equipment.
The ESP90x family integrate the benefits of Ethernet communications with existing serial devices by
offering the combination of three serial interfaces, RS-232, RS-422, and RS-485. The Ethernet connection
will auto select 10BaseT or 100BaseTX.
These serial servers provide Windows host control over serial devices located virtually anywhere on a
TCP/IP or UDP/IP Ethernet connection. They even give authorized users control over the connected serial
device and the server configuration from anywhere outside the LAN.
