3.3.4. Backup EEPROM to Flash
This backup function could recover settings from the Flash to the EEPROM if the settings in the EEPROM are lost. If
SE5001A detects that there is an EEPROM backup in the flash. It will compare the backup values in the Flash and
EEPROM. If the values do not match, it will write the backup settings in the Flash to the EEPROM. To enable this
function, follow Figure 3.21 in the Security Settings.
 Click on Backup EEPROM to back up the settings from the EEPROM to the Flash. SE5001A would then
show Have Backup.
 Click on Erase Backup to erase the settings stored in the Flash. SE5001A would then show No Backup.
3.3.5. Link Mode Configuration
SE5001A supports different Link Modes, which are TCP Server, TCP Client, and UDP (Figure 3.22). Under the three
Link Modes, TCP Server can support Virtual COM, Pair Connection, or Reverse Telnet applications. TCP Client can
support Virtual COM or Pair Connection application. If none of the application is enabled, the SE5001A will run in
RAW mode. In the upcoming sections, we will discuss how to setup different Link Modes properly.
Figure 3.22 Link Modes
3.3.6. Link Mode: Configure SE5001A as a TCP Server
SE5001A defaults in TCP Server mode, there are additional connection settings that can be configured (Figure 3.23).
By selecting the TCP Server mode, a TCP Client program should be prepared to connect to SE5001A.
 Click on the “COM1” link on the left hand side.
 Select TCP Server. TCP Server is the default link mode.
 Enter the Local Listening Port. This is the port specified in the TCP Client program connecting to the serial
device server. The default local port is 4660.
 IP Filter: Only the designated IP address will be able to access the COM port if this option is enabled. This
option is disabled by default.
 TCP Keep-Alive: Specify the interval in the “Idle Time Before Sending TCP Alive Packet” to force
SE5001A to send TCP Keep-Alive packets in the set interval to prevent disconnection from the client. Note
that this field has a multiplier of 10, so the default value 4 means to send Keep-Alive packets every 40
seconds.
 TCP Inactivity Timeout: Specify the value in “TCP Inactivity Time Before Disconnect” to force SE5001A
actively close a TCP connection after some specific inactivity time (no packets). The default value is 0,
which means the SE5001A would never actively close an established connection.
