NPort 6000 Series User’s Manual Configuring Serial Port Operation Modes
7-14
Option Description
Startup/None (default) A TCP connection will be established on startup, and will remain active
indefinitely.
Any Character/None A TCP connection will be established when any character is received
from the serial interface, and will remain active indefinitely.
Any Character/
Inactivity Time
A TCP connection will be established when any character is received
from the serial interface, and will be disconnected when Inactivity time
is reached.
DSR On/DSR Off A TCP connection will be established when a DSR “On” signal is
received, and will be disconnected when a DSR “Off” signal is
received.
DSR On/None A TCP connection will be established when a DSR “On” signal is
received, and will remain active indefinitely.
DCD On/DCD Off A TCP connection will be established when a DCD “On” signal is
received, and will be disconnected when a DCD “Off” signal is
received.
DCD On/None A TCP connection will be established when a DCD “On” signal is
received, and will remain active indefinitely.
Packet length (default=0): This field refers to the maximum amount of data that is allowed to
accumulate in the serial port buffer before sending. At the default of 0 for packet length, no
maximum amount is specified and data in the buffer will be sent as specified by the delimiter
settings or when the buffer is full. When a packet length between 1 and 1024 bytes is specified,
data in the buffer will be sent as soon it reaches the specified length.
Delimiter 1 and Delimiter 2 (default=None): 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 specified in the Delimiter 2
field, so that both characters act as the delimiter to indicate when data should be sent.
ATTENTION
In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled
in conjunction with Delimiter 1 and never on its own; otherwise there may be data errors. Even
when a delimiter is enabled, the NPort 6000 will still pack and send the data when the amount of
data exceeds 1 KB.
Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is
handled when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If
Delimiters 1 and 2 are both enabled, both characters must be received for the delimiter process to
take place.
y Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
y Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following
the delimiter.
y Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received
following the delimiter.
y Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.
Force transmit (default=0 ms): This parameter defines how large a gap in serial communication
the NPort 6000 will allow before packing the serial data in its internal buffer for network
transmission.
