NPort IA5150/5250 Series User's Manual
ATTENTION
When Max connection is set to 2, 3, or 4, this means that NPort IA5150/5250 will be using a
"multi connection application" (i.e., 2, 3, or 4 hosts are allowed access to the port at the same
time). When using a multi connection application, NPort IA5150/5250 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 NPort IA5150/5250's console setting, data communication may not work properly.
Ignore jammed IP
Setting
No or Yes
Previously, when Max connections > 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. Currently, 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
Yes or No
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 NPort IA may get configuration changes from multiple hosts, the most
recent command received will take precedence.
Packing length
Setting
0 to 1024
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
00 to FF (hex)
Delimiter 2
Setting
00 to FF (hex)
Once the NPort IA5150/5250 receives both delimiters through its serial port, it immediately packs
all data currently in its buffer and sends it to the NPort IA5150/5250's Ethernet port.
