Moxa provides CN2610 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 Æ CN2610 Æ Serial Device Serial Device Æ CN2610 Æ 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
CN2610’s Ethernet port.
4. CN2610 converts the Ethernet packets
back into RS-232 serial format.
5. The commands are delivered to serial
device(s) connected to CN2610’s serial
port(s).
1. A serial device connected to CN2610 starts
transmitting serial data.
2. CN2610 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 CN2610 to access serial devices over an
Ethernet network, and since CN2610 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 CN2610, as shown in the figure.
Refer to Chapter 4 for detailed information and configuration instructions.
