20 ESP Serial Hub Installer/User Guide
Destination IP
port number
[base]
Specifies the IP port number on which the remote server is listening. Valid values are 0-65535.
(If the destination IP port is on an ESP hub, 4000 and 4100 should not be used.)
If the all ports option is being used for configuration, this value specifies the destination IP
port base. Each port’s actual destination IP port number will be the base plus the port
number. For example, if 6000 is specified as the destination IP port base, the destination IP
port number for port 1 will be 6001, port 2 will be 6002 and so on.
The default value is 4001 for port 1, 4002 for port 2 and so on.
Local IP port
number [base]
Specifies the IP port number for the embedded TCP client.
If the all ports option is being used for configuration, this value specifies the local IP port base.
Each port’s actual local IP port number will be the base plus the port number. For example, if
6000 is specified as the base, the local IP port number for port 1 will be 6001, port 2 will be
6002 and so on.
This value (or its result when using the all ports option) must meet the following criteria:
• It cannot conflict with the port numbers specified for other enabled connection methods on
any port.
• Valid values are 1024-65535, except 4000 and 4100, which are reserved.
• When using the all ports option, 4000 or 4100 may be used as the base. However, you
cannot specify a base that, when added to a port number, will equal 4000 or 4100.
When using the all ports option, all ports must be valid or the entire selection will not
be accepted.
The default value is 4001 for port 1, 4002 for port 2 and so on.
Inactivity time-
out
Specifies the length of time before the TCP session is disconnected if there is no activity.
Valid values are 0-65535 seconds. A 0 value disables the inactivity time-out.
For example, a value of 60 indicates the TCP session will be disconnected if there is no
activity for a period of 60 seconds.
The default value is 0 (disabled).
Connection
mode
Specifies the criteria for establishing the TCP connection. Valid values are:
Always Connect Always attempt to establish the TCP connection.
Connect on Data The TCP connection will be established upon receiving the first data
character from the serial port.
Connect on DCD (Valid only on RS-232 ports.) The TCP connection will be established
when the DCD signal is logically high.
The default value is Always Connect
Serial
buffering
Specifies the length of time accumulated serial data should be buffered before being sent to
the remote server. Valid values are 0-65535 hundredths of a second. A 0 value indicates that
data will be sent as soon as it is available.
For example, a value of 100 indicates that once serial data is received, it will remain buffered
up to 1 second (100 hundredths of a second), at which time all data will be sent.
If the buffer becomes half full, the time is ignored and the data is sent.
The default value is 0 (send immediately).
