NPort 5000AI-M12 Series Web Console Configuration
5-19
ATTENTION
T
he Inactivity time should be configured to be larger than the Force transmit timeout setting
. To prevent
the unintended loss of data due to the session disconnect
ion, it is highly recommended that you set
this value
large enough so that th
e intended data transfer is completed.
Max connection
Setting Factory Default Necessity
1, 2, 3, 4, 5, 6, 7, 8
1
Required
Max connection is usually used when the user needs to receive data from different hosts simultaneously. The
factory default only allows for 1 connection at a time.
Max connection 1: The NPort only allows 1 host to open the TCP connection to the specific serial port.
Max connection 2 to 8: Allows 2 to 8 host’s TCP connection request to open this NPort 5000AI-M12 serial port,
at the same time. When multiple hosts establish a TCP connection to the specific serial port at the same time,
the NPort 5000AI-M12 will duplicate the serial data and transmit to all of the hosts. Ethernet data is sent on a
first-in-first-out basis to the serial port when data comes into the NPort 5000AI-M12 from the Ethernet
interface.
Ignore jammed IP
Setting Factory Default Necessity
No or Yes No Optional
By default, when Max connection is greater than 1, and the serial device is transmitting data, if any one of the
connected hosts is not responding, it will wait until the data has been transmitted successfully before
transmitting the second group of data to all hosts.If you select Yes for Ignore jammed IP, the host that is not
responding will be ignored, but the data will still be transmitted to the other hosts.
Allow driver control
Setting Factory Default Necessity
No or Yes No Optional
If Max connection is greater than 1, the NPort will ignore driver control commands from all connected hosts.
However, if you set Allow driver control to Yes, control commands will be accepted. Note that since the
NPort 5000AI-M12 may get configuration changes from multiple hosts, the most recent command received will
take precedence.
Packing length
Setting Factory Default Necessity
0 to 1024 0 Optional
Default = 0, The Delimiter Process will be followed, regardless of the length of the data packet. If the data
length (in bytes) matches the configured value, the data will be forced out. The data length can be configured
for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.
Delimiter 1
Setting Factory Default Necessity
00 to FF None Optional
Delimiter 2
Setting Factory Default Necessity
00 to FF None Optional
Once the NPort 5000AI-M12 receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it out the NPort 5000AI-M12’s Ethernet port.
