Using Setup Mode for Configuration
Trigger Setup
A trigger event can occur when the unit receives two bytes of a specified sequence
on the serial port, or because of a specified combination of conditions on the
configurable pins.
If the serial sequence is set to 00,00, the trigger is disabled. At the Serial Sequence
prompt, enter the ASCII Hex value. Example: A two byte sequence of 12 would be
0x31, 0x32.
If the configurable pins are all set to X (Don’t Care), then they are disabled. If both
the serial sequence and the configurable pins are disabled, the trigger is disabled.
Note: You can set the configurable pins to A = Active, I = Inactive, or X =
Don’t Care. Active can mean Active Low or Active High. To change the
configurable pins’ settings, you must use DeviceInstaller or send setup
records to Port 77FE.
Message The subject line of the e-mail.
Priority L is for normal priority; H is for high priority.
Min. notification
interval The minimum time allowed between individual triggers. If
a trigger event occurs faster than the minimum interval,
the unit ignores the trigger.
Re-notification interval If a single trigger event stays asserted, then the unit
sends an e-mail message at this time interval.
Each trigger is independent of the others. Each condition within an individual trigger
must be met before the unit will send the e-mail.
Expert Settings
Note: You can change these settings via Telnet or serial connections only,
not on the Web-Manager.
Caution: Only an expert should change these parameters. You must
definitely know the consequences the changes might have.
TCP Keepalive time in s
(1s – 65s; 0s=disable) (45)
ARP Cache timeout in s
(1s – 600s) (600)
TCP Keepalive time in seconds
This option allows you to change how many seconds the unit will wait during a silent
connection before attempting to see if the currently connected network device is still
on the network. If the unit then gets no response, it drops that connection.
ARP Cache timeout in seconds
Whenever the unit communicates with another device on the network, it adds an
entry into its ARP table. The ARP Cache timeout option allows you to define how
many seconds (1-600) the unit will wait before timing out this table.
