Windows Real COM (NT Real COM)
Moxa provides CN2510 COM port drivers for all Windows operating systems. The COM port driver serves a dual
purpose
—
(1) convert serial data into Ethernet packets, (2) convert Ethernet packets into serial data
—
as
outlined in the following table:
PC
CN2510

PC
1.
The PC generates RS-232 serial COM commands.
2.
The COM port driver converts the commands
into Ethernet packets.
3.
The packets are sent over the network to CN2510’s
Ethernet port.
4.
CN2510 converts the Ethernet packets back into
RS-232 serial format.
5.
The commands are delivered to serial device(s)
connected to CN2510’s serial port(s).
1.
A serial device connected to CN2510 starts
transmitting serial data.
2.
CN2510 converts the data into one or more
Ethernet packets.
3.
The packets are sent over the network to the PC
host’s Ethernet port.
4.
The COM port driver converts the Ethernet
packets back into RS-232 serial format.
5.
The serial data is processed by the program that
controls the serial device.
You can enhance your applications greatly by using CN2510 to access serial devices over an Ethernet network,
and since CN2510 and the COM driver handle all protocol conversion tasks, you won’t need to modify the
software currently in use. In fact, multiple PCs can access the serial ports of one CN2510, as shown in the
figure.
