Table 10: Raw TCP Client Connection Method Configurable Items (Continued)
Item
Description
Specifies the length of time before the TCP session is disconnected if there is
no activity. Valid values are 0-65535 seconds.
Inactivity time-
For example, a value of 60 indicates the TCP session will be disconnected if
out
there is no activity for a period of 60 seconds.
A 0 value disables the inactivity time-out. The default value is 0 (disabled).
Specifies the criteria for establishing the TCP connection. Valid values are:
Connection
Autostart
mode
Connect on Data
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.
For example, a value of 100 indicates that once serial data is received, the
Serial
ESP-2 hub will buffer the data until 1 second (100 hundredths of a second) has
buffering
elapsed, at which time all data will be sent.
A 0 value indicates that data will be sent as soon as it is available.
The default value is 0 (send immediately). If the buffer becomes half full, the
time is ignored and the data is sent.
Enables or disables buffering of received serial data while waiting for a TCP
connection to be established. The default value is disabled.
Idle TCP
When enabled, the most recent 20K bytes of data are held in an internal buffer.
buffering
Once the connection is established, the buffered serial data is sent to the
remote endpoint of the TCP connection.

3.5 Configuration Utility

The configuration utility connection method may be used on either of the ESP-2 serial
ports. Using the internal configuration utility, you may specify attributes of the ESP-2
hub and its serial ports. This includes enabling serial port connection methods and
specifying their configurable items, plus configuring serial port attributes. The menu-
based interface also allows you to configure network parameters, download and
install FLASH images, reboot, reinitialize and monitor ESP-2 hub status.
See Configuration Utility on page 24 for more information.
Table 11 describes this method's configurable items for each serial port.
