NPort S8000 Series Basic Settings and Device Server Configuration
5-10
Data will be sent first-in-first-out when data enters the NPort S8000 from the Ethernet interface.
ATTENTION
When Max connection is
set to 2 to 8, this means that the NPort use a “multi connection application” (i.e., 2
to
8
hosts are allowed access to the port at the same time). When using a multi connection application, the
NPort
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’s
console setting, data communication may not work properly.
Ignore jammed IP
Setting Factory Default Necessity
Enable or Disable Disable Optional
Previously, if “max connection” was greater than 1, the serial device was transmitting data, and a connected
host was not responding, the NPort would wait until the data was transmitted successfully before transmitting
the second group of data to all hosts. Currently, if you select Enable 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
Enable or Disable Disable 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
S8000 may get configuration changes from multiple hosts, the most recent command received will take
precedence.
Connection goes down
Setting Factory Default Necessity
Always High or Always
Low
Always High Optional
You can configure what happens to the RTS and DTR signals when the Ethernet connection goes down. For
some applications, serial devices need to know the Ethernet link status through RTS or DTR signals sent
through the serial port. Use always low if you want the RTS and DTR signal to change their state to low when
the Ethernet connection goes down. Use always high if you do not want the Ethernet connection status to
affect the RTS or DTR signals.
Data Packing
Packet 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
When Delimiter 1 is enabled, the serial port will clear the buffer and send the data to the Ethernet port when
a specific character, entered in hex format, is received. A second delimiter character may be enabled and
