Data Collection, Storage, and Polling
Depending on the configuration of the DL50, a unit may store data received from an RS-232 serial
device on one or both ports. The data received on each port can be stored and handled
independently from any other port. The unit can also generate and store alarm records based on
data alarm monitoring. These records are stored in the Alarms file, which can be polled just like
any of the serial port data files.
There are several methods available to poll these files. Serial transfer through the command port
allows an administrator to connect to the DL50 and poll the records from each file via Xmodem,
CBB, line, or compressed line modes. Line mode releases the data just as it was entered with no
printable character manipulation. Compressed line mode uses a white space compression
algorithm to speed up data transfer.
The same methods used in serial command mode transfer can be used via both modem and Telnet
command modes. Refer to Chapter 6, Command Reference, for more information on manual data
release commands.
Records stored within the DL50 can also be polled by means of FTP. The records can be
delivered automatically via FTP push. FTP push is accomplished by the DL50 opening a
predefined FTP connection at a specific interval and uploading all selected files.
Remote Access
The DL50 provides an administrator with transparent access to devices connected to the serial
ports of the unit via pass-through connections. These can be accessed via the command processor
or through Telnet ports. This sort of access can be used to configure, maintain, or manipulate
devices that would normally have no remote access.
Alarm Monitoring
The DL50 has the capability to monitor incoming data for user-defined strings and then report the
alarm via several avenues. Both of the ports on the unit can be monitored by one of two different
data alarm families. Each of these families may contain up to 16 individual alarm monitors. Each
monitor contains independent actions, counters, and other unique settings.
The DL50 has the ability to trigger an alarm at scheduled days and times, 80% memory full, and
after user-specified periods when no-data is received. Each of these alarms can use the same
notification methods as the data alarms.
Data alarms triggered within the DL50 are logged via the alarms file mentioned in the previous
section. This file can be obtained in the same fashion as any other data file within the unit.
Alarm Notification
The DL50 is equipped to use several different methods to notify an administrator of alarms
detected within the unit. The unit can send SNMP traps to enterprise management software or
Omnitronix Alarm Manager (available at
http://www.omnitronix.com
or via Omnitronix technical
support). It can use the internal modem to perform either a numeric page or command processor
callout.
