Settings for RealCOM Mode
When Mode is set to RealCOM on the Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, Max connection, and Delimiter 1 and 2.
TCP Alive Check Time
Default
7 min
Options
0 to 99 min
Description
This field specifies how long the module will wait for a response to “keep alive”
packets before closing the TCP connection. The module checks connection
status by sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no response to the
“keep alive” packets.
1 to 99: If the remote host does not respond to the packet within the specified
time, the module will force the existing TCP connection to close.
Max Connection
Default
1
Options
1 to 4
Description
This field specifies the maximum number of connections that will be accepted
by the serial port.
1: Only one specific host can access this serial port, and the Real COM driver
on that host will have full control over the port.
2 to 4: This serial port will allow the specified number of connections to be
opened simultaneously. With simultaneous connections, the Real COM driver
will only provide a pure data tunnel with no control ability. The serial
communication will be determined by the module rather than by your
application program. Application software that is based on the Real COM driver
will receive a driver response of “success” when using any of the Win32 API
functions. The module will send data only to the Real COM driver on the host.
Data received from hosts will be sent to the attached serial device on a
first-in-first-out basis.
