AWK-1121/1127 Web Console Configuration
3-22
Mode
Along with Application, this field specifies the serial port’s operation mode, or how it will interact with network
devices. Depending on how Application is configured, different options are available for Mode. Depending on
how Mode is configured, additional settings will be available for configuration.
Setting Description Factory Default
RealCOM
This serial port will operate in RealCOM mode.
(depends on
Application)
RFC2217 This serial port will operate in RFC2217 mode.
TCP Server This serial port will operate in TCP Server mode.
TCP Client This serial port will operate in TCP Client mode.
UDP This serial port will operate in UDP mode.
RealCOM Mode
RealCOM
mode is designed to work with AWK
drivers that are installed on a network host. COM
drivers are provided for Windows systems, and TTY
drivers are provided for Linux and UNIX systems.
The driver establishes a transparent connection to
the attached serial device by mapping a local serial
por
t to the AWK-1127 serial port. RealCOM mode
supports up to four simultaneous connections, so
multiple hosts can collect data from the attached
device at the same time.
ATTENTION
Real
COM drivers are installed and configured through OnCell Windows Driver Manager.
RealCOM mode allows you to continue using your serial communications software to access devices that are
now attached to your AWK-1127. On the host, the AWK RealCOM driver automatically intercepts data sent to
the COM port, packs it into a TCP/IP packet, and redirects it to the network. At the other end of the connection,
the AWK-1127 accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the
appropriate device.
ATTENTION
In RealCOM mode, two
hosts can have simultaneous access control over the AWK-1127 serial port.
