What is a DL30
Basics
The DL30 is a hardware device that provides three basic functions to facilitate management and
monitoring of attached serial port devices. These functions are:
●Data collection, storage and forwarding
●Remote access of attached serial devices
●Monitoring of serial data alarm conditions
The DL30 has a diverse selection of communication methods available for different applications.
The following methods can be used to either access the command processor or provide a pass-
through connection to devices connected to the Input port:
●RS-232 serial
●Modem (if optional modem installed)
●Telnet (if optional Ethernet installed)
●FTP (if optional Ethernet installed)
Data may be retrieved from or through the DL30 by any of the following methods depending on
the hardware configuration:
●Serial or modem connection to command processor (using Line or Zmodem) or pass-
through
●Telnet to command processor or pass-through
●Inline Mode (data in Input port, out the Output port)
●FTP push (automatic delivery to FTP server)
●FTP get (manual retrieval from FTP server)
Alarms generated or detected within the DL30 can be delivered as “OmniAlarms” via the modem
as described later in this manual.
Parts Identification
The base DL30 comes with the following standard onboard components:
●DB9 Male RS-232 serial port (Input)
●DB9 Female RS-232 serial port (Output)

Front Panel LEDS
●Power
The Power LED will remain on steady when power is applied to the unit
●Percent Full
The DL30 has four LEDs to indicate file full status. A blinking Percent Full LED indicates
the file database has less than the amount indicated by that LED, but more than the
previous. A solid lit LED indicates the file database percentage is at or over the value for
that LED.
●Link
The Link LED flashes whenever data is transmitted on the Ethernet port.
●In
The In LED flashes whenever data is received on the Input port.
●Out
The Out LED flashes whenever data is received on the Output port.

2005 Omnitronix, Inc. 8
Back Panel
The Input port is configured to automatically detect DTE/DCE and baud rate.
Default settings for the serial ports are 19200 baud, 8-bit word length, No parity, and one stop bit
(19200 8N1). Use either the internal Setup menu or the external dip switches to adjust the
settings of either serial port.
●Ethernet
The Ethernet 10BaseT connector (if installed) is an RJ-45. Connect a network cable from
an Ethernet hub or switch to this port.
●Internal Modem
The 33K internal modem connector (if installed) is an RJ-11. Connect a POTS
(analog) phone line to this port.

Features
Data Collection and Storage
The DL30 stores data received from an RS-232 serial device. The data received on the Input
port is stored in File 1.
Polling
There are four methods available to poll the data from File 1:
●Line mode via the Output port, modem, or telnet
Line mode releases data just as it was entered with no printable character
manipulation. Line mode is not recommended as a polling method because there is no
error checking.
●Zmodem via the Output port, modem, or telnet
Data can be polled using a terminal emulator or other software that supports the
Zmodem protocol. Zmodem transfers data in blocks and uses error checking to ensure
accuracy.
●Inline mode via the Output port
The Output port can be changed from a command port to Inline port (set dip switch
SW12 ON). Inline mode links the Output port to the Input port so that data received on
the Input port is immediately released out the Output port to a PC running polling
software. In the event the communication link with the PC fails, the DL30 will then
begin buffering call records. When the link becomes available again, buffered data will
be released based on the handshaking mode configured in the Serial Port setup menu.
●FTP - either FTP push or FTP get
In a DL30 equipped with an Ethernet port, the data buffered in File 1 can be
polled via FTP in one of two ways:
1) FTP push – the DL30 can be configured in the Network Settings menu to
“push” the data in File 1 to an FTP server at specific intervals. Once the remote
host has received the data, it is automatically deleted from the DL30.
2) FTP get – the DL30 has a built-in FTP server that allows inbound connections
for the purpose of retrieving data. The user can make an FTP connection to the
DL30 and issue the “get File1” command to poll the data.
Remote access (pass-through)
The DL30 provides a user with transparent access to devices connected to either serial port via
pass-through connections. Remote access can be used to configure, maintain, or manipulate
devices that would normally have no remote access. A pass-through connection can be made
via a serial connection to the Output port, modem or telnet.
•Via serial connection to Output port or modem
From the command line enter the command “Bypass1” to connect to the Input
port, and “Bypass 2” (modem connection only) to connect to the Output port.
“Bypass” by itself will connect to the Output port by default.
•Via Telnet
Telnet to the DL30 IP address followed by port number 2101 or 2102 for either
the Input port or the Output port.
(example: telnet 192.168.100.19 2101 will connect to the Input port)
Data Alarm Monitoring
The DL30 can be configured to monitor data coming in the Input port for user-defined Data Alarm
Strings and then report the alarm via the modem using OmniAlarms (see Alarm notification
below) or via the Ethernet port using SNMP traps (not implemented yet).

2005 Omnitronix, Inc. 11
Alarm Notification
Incoming data that matches the Data Alarm Strings can trigger two types of actions; an
OmniAlarm delivered via the modem, or an SNMP trap delivered via the network (not
implemented yet). The modem number to be called, or the IP address of the SNMP Manager to
which the trap is sent, are configured in the Alarms Settings menu.
OmniAlarms
OmniAlarms are a receipt-verified alert system delivered via modem.
When an OmniAlarm is initiated, the box dials the callout number specified by the action. Once
connected, it sends a header and waits for a specific response. If the DL30 receives a specific
response to the header, it delivers alarms in CRC mode; otherwise, alarms are delivered in non-
CRC mode. In CRC mode, each OmniAlarm is transmitted with some extra control characters
and a CRC, and the remote host is required to acknowledge each alarm in a certain format.
After all OmniAlarms have been delivered, the box waits for 20 seconds for any type of keystroke.
If a keystroke is detected, the box will present a login menu.
OmniAlarm Protocol
Initial header
Upon dialing into the receiver, the DL30 will send a message similar to the following:
Data-Link DL30
Server Room B
Omnitronix Alarm Notice ver. 1.00
(CR/LF)(ENQ)
•The first line of the output is the DL30 answer string.
•The second line is the DL30 unit ID.
•The third line indicates the version of OmniAlarm.
•The final line is the (ENQ) control code.
Non-CRC Mode
After sending the initial header, the DL30 pauses for 10 seconds to wait for an ACK from the
receiver. Non-CRC mode requires the Require OmniAlarm ACKs is setting to be turned off. If
the DL30 sees no response or the receiver replies with:
(ACK)00(ACK)
then non-CRC mode is assumed and the sender will transmit the alarms. The control characters
(SOH), (SOT), and (ETX) are not transmitted in non-CRC mode.
CRC Mode
CRC mode exists to ensure that event notifications are delivered intact. OmniAlarms delivered in
CRC mode have extra control characters and a 16-bit CRC included in each alarm to allow for
error detection by the receiver. Additionally, CRC mode causes the DL30 to store and later retry
each alarm until a proper acknowledgement is received from the receiver.
If Require OmniAlarm ACKs is enabled, the DL30 will require a positive CRC mode response or it
will disconnect and retry the call. To enable CRC, the receiver must respond with the following
after the header is received:
(ACK)01(ACK)

2005 Omnitronix, Inc. 12
Once CRC mode is enabled, each alarm must be acknowledged by a message in the following
format:
(ACK)XX(ACK)
XX represents the alarm ID to acknowledge. The ID can be found in the first line of each record
sent by the DL30.
Alarm Transmission
After successfully initiating a session, alarms are delivered in the following format:
(SOH)ID=XX(SOT)
Date=06/01/04
Time=10:30:02
TargetPort=
TargetName=
AlarmType=Data Alarm
AlarmName=Test Alarm
Threshold=0
Severity=Critical
Text1=text record line
Text2=text record line
(ETX)XX
(CR/LF)
(CR/LF)
•The alarm ID indicates the index number of each alarm delivered during a call. This
number restarts at 1 for each new call.
•The severity line represents the Class value defined for this alarm.
•Up to twelve lines of Textnmay be sent.
•XX represents the 16-bit CRC if CRC mode is enabled. If not, this line will contain two
spaces.
If additional alarms are queued to be sent in the same transmission, the above output is
repeated, incrementing the ID with each alarm. When non-CRC alarm transmission is selected,
alarms are sent with a 5 second delay between each. When all alarms and been transmitted,
then DL30 sends the following:
(EOT)
(CR/LF)
(CR/LF)
At this point, the DL30 waits 20 seconds for the receiver to send any input, and then hangs up. If
any commands are received, a command prompt is established and the connection will remain
active.
