CN2600 Series Serial Port Operation Modes
ared to TCP communication, UDP is faster and more
efficient. In UDP mode, you can unicast or multi
unicast data
from a serial device to one or multiple host computers and the
serial device can receive data from one or multiple host
computers. These traits make UDP mode especially suited for
message display applications.
Redundant COM
The Redundant COM operation mode can be used to set up a redundant LAN between the serial devices
connected to the CN2600’s serial ports and the host computer. The redundant structure involves using the
CN2600’s two LAN ports to set up two independent LANs that connect the CN2600 to the host computer. If
either of the two LANs fails, the other LAN will continue transmitting packets between the serial devices and the
host, with the packets passing through the CN2600. In fact, one of the biggest advantages of the CN2600’s
Redundant COM mode is that the “switching time” is zero.
ATTENTION
If either LAN gets disconnected, it will take at le
ast 1 minute for the LAN to recover after reconnecting.
If both LANs get disconnected, you will need to re
-open your application software’s COM port for data to
