Send Serial Heartbeat should only be enabled if the Lane Controller is able to respond to hearbeat messages. LC

Retry Timeout

Navigate to the General page, and review the Switchover panel:

Toggle Switchover on serial LC link down and/or Switchover on Ethernet LC link down, as required.

Note: When setting the LC Retry Timeout, consider the baud rate used to communicate with the LC and the

processing speed of the LC to avoid false failure reports.

If Switchover on Serial Link Down is enabled, from the LC Serial panel on the Lane Controller page, enter a

time, in milliseconds, in the LC Retry Timeout field. If an LC does not respond within this time, the Reader will

consider serial communications to the LC to be down and will trigger a switchover if the SPM redundancy mode

switch is in AUTO.

If Switchover on Ethernet LC Link Down is enabled, enter a time, in milliseconds, in the LC Ethernet TCP-Socket

Timeout text box. If an LC does not respond within this time, the Reader will consider Ethernet communications to

the LC to be down and could trigger a switchover if the SPM redundancy mode switch is in AUTO.
