NPort 5100 Series Web Console Configuration

5-13

Max connection is usually used when the user needs to receive data from different hosts simultaneously. The

factory default only allows 1 connection at a time.

Max. connection 1:

NPort only allows 1 host to open the TCP connection to the specific serial port.

Max connection 2 to 4:

Allows 2 to 4 host’s TCP connection request to open this NPort 5100 serial port, at the same time. When

multiple hosts establish a TCP connection to the specific serial port at the same time, NPort 5100 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 NPort 5100 from the Ethernet interface.

Ignore jammed IP

Setting Factory Default Necessity

No or Yes No Optional

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 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

5100 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 5100 receives both delimiters through its serial port, it immediately packs all data currently in

its buffer and sends it out the NPort 5100’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

5100 will automatically pack the data and send it to the Ethernet.

However, to use the delimiter 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.
