Serial Port Profiles

Adding/Editing Additional Hosts

You can define a list of hosts that the serial device will communicate to or a primary/backup host.

Configure the following parameters:

Adding/Editing a Multihost Entry

When you click the Add or Edit button, the Host Entry window appears. The hosts in the multihost

list must already be defined (see

Host Table to learn how to create a host). If you add a host that was

defined with its fully qualified domain name (FQDN), it must be resolvable by your configured DNS

server.

Configure the following parameters:

Define additional

hosts to connect to

When this option is enabled, you can define up to 49 hosts that the serial device

connected to this serial port will attempt communicate to. With this mode of

operation, the IOLAN will connect to multiple hosts simultaneously.

Default: Enabled

Add Button Click the Add button to add a host to the list of hosts that will be receiving

communication from the serial device connected to the IOLAN.

Edit Button Highlight an existing host and click the Edit button to edit a host in the list of

hosts that will be receiving communication from the serial device connected to

the IOLAN.

Delete Button Click the Delete button to delete a host to the list of hosts that will be receiving

communication from the serial device connected to the IOLAN.

Define a primary

host and backup...

When this option is enabled, you need to define a primary host that the serial

device connected to this serial port will communicate to and a backup host, in

the event that the IOLAN loses communication to the primary host. The

IOLAN will first establish a connection to the primary host. Should the

connection to the primary host be lost (or never established), the IOLAN will

establish a connection the backup host. Once connected to the backup, the

IOLAN will attempt to re-establish a connection to the Primary host, once this

is successfully done, it gracefully shuts down the backup connection.

Default: Disabled

Primary Host Specify a preconfigured host that the serial device will communicate to through

the IOLAN.

Default: None

TCP Port Specify the TCP port that the IOLAN will use to communicate to the Primary

Host.

Default: 0

Backup Host Specify a preconfigured host that the serial device will communicate to through

the IOLAN if the IOLAN cannot communicate with the

Primary Host.

Default: None

TCP Port Specify the TCP port that the IOLAN will use to communicate to the Backup

Host

Default: 10000

Host Name Specify the preconfigured host that will be in the multihost list.

Default: None
