140 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Advanced Tab Field Descriptions
Configure the following parameters:
Authenticate User Enables/disables login/password authentication for users connecting from the
network.
Default: Disabled
Enable TCP
Keepalive
Enables a per-connection TCP keepalive feature. After the configured number
of seconds, the connection will send a gratuitous ACK to the network peer,
thus either ensuring the connection stays active OR causing a dropped
connection condition to be recognized.
This parameter needs to be used in conjunction with
Monitor Connection
Status Interval
parameter found in the Serial, Advanced, Advanced Settings
tab. The interval specifies the inactivity period before "testing" the connection.
Default: Disabled
Enable Message of
the Day (MOTD)
Enables/disables the display of the message of the day.
Default: Disabled
Enable Data
Logging
When enabled, serial data will be buffered if the TCP connection is lost. When
the TCP connection is re-established, the buffered serial data will be sent to its
destination (this option is not available when
Monitor DSR, Monitor DCD, or
Multihost is enabled).
The data buffer is 4K for desktop models and 32K for rack mount and medical
unit models. If the data buffer is filled, incoming serial data will overwrite the
oldest data.
Default: Disabled
Idle Timeout Use this timer to close a connection because of inactivity. When the Idle
Timeout expires, the IOLAN will end the connection.
Range: 0-4294967 seconds (about 49 days)
Default:
0 seconds so the port will never timeout
Session Timeout Use this timer to forcibly close the session/connection when the Session
Timeout
expires.
Default:
0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
