NPort 6000 Series Configuring Serial Port Operation Modes
7-5
• Del 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
• Del 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.
Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the NPort
6000 will allow before packing the serial data in its internal buffer for network transmission.
Reverse Real COM Mode
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response
to “keep alive” packets before closing the TCP connection. The NPort 6000 checks the connection status by
sending periodic “keep alive” packets. If the remote host does not respond to the packet within the time
specified in this field, the NPort 6000 will force the existing TCP connection to close. For socket and device
control modes, the NPort 6000 will listen for another TCP connection from another host after closing the
connection. If TCP alive check time is set to 0, the TCP connection will remain open and will not send any “keep
alive” packets.
Ignore jammed IP (default=Disable): This option determines how the Nport will proceed if multiple hosts
are connected and one or more of the hosts stops responding as the port is transmitting data. If you select
disable, the port will wait until the data has been transmitted successfully to all hosts before transmitting the
next group of data. If you select Enable, the port will ignore the host that stopped responding and continue data
transmission to the other hosts.
Allow driver control (default=Disable): This option determines how the port will proceed if driver control
commands are received from multiple hosts that are connected to the port. If disable is selected, driver control
commands will be ignored. If Enable is selected, control commands will be accepted, with the most recent
command received taking precedence.
Secure (default=Disable): If you select Enable, data sent through the Ethernet will be encrypted with SSL.
