NPort 6000 Series Configuring Serial Port Operation Modes
7-6
ATTENTION
If an NPort 6000 serial port is in Reverse Real COM mode and configured for SSL encryption, make sure the
Reverse Real COM driver is configured the same way. This is done through the NPort Windows Driver
Manager, which is installed with the driver. Please refer to Chapter 10, Software Installation and
Configuration, for more information.
Destination address 1 through 2 (default=None): Specifying an IP address allows the NPort 6000 to
connect actively to the remote host. At least one destination must be provided.
TCP port (default=60950): This is the TCP port number assignment for the Remote Host/Server. It is the
port number that the serial port of NPort 6000 uses to establish the connections with a Remote Host/Server. To
avoid conflicts with well known TCP ports, the default is set to 60950.
ATTENTION
Up to 2 connections can be established between the NPort 6000 hosts. Make sure that port 60950 is not
blocked by the firewall before using this port.
ATTENTION
The destination ip address parameter can be the IP address, domain name, or the name defined in the host
table.
Designated local port 1 through 2 (default=7010 through 7320): Use these fields to specify the
designated local ports.
Connection goes down (default=always high): 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.
Packet length (default=0): The Packet length setting 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 control 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.
• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Del 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
