NPort 5000AI-M12 Series Web Console Configuration
5-14
ATTENTION
When “
Max connection” is set greater than 1, this means that the NPort 5000AI-M12 will be using a “multi
connection application” (i.e.,
Up to 8 hosts are allowed access to the port at the same time). When using a
multi connection application,
the NPort 5000AI-M12 will use the serial communication parameters set in
the
console.
All of the hosts connected to that port must use the same serial settings. If
one of the hosts opens
the COM
port with parameters that are different from the NPort 5000AI-M12’s console setting, data
communication may not work properly.
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 under 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, 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 (hex) None Optional
Delimiter 2
Setting
Factory Default
Necessity
00 to FF (hex) 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 to the NPort 5000AI-M12’s Ethernet port.
ATTENTION
Delimiter 2
is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer.
If the size of the serial
data received is greater than 1 KB, the NPort
5000AI-M12
will automatically pack the data and send it to the
Ethernet port.
However, to use the deli
miter function, you must at least enable Delimiter 1. If Delimiter 1 is
left blank and Delimiter 2 is enabled, the delimiter function will not work properly.
