attempts indefinitely.
5. If there is an error message or no response from the router, first check the network settings
and connection, then consult a System Administrator or Omnitronix technical support.
6. Verify the PC running AlarmManager by repeating step 3 with the IP address of that
computer. The output from this command should be similar to that of the previous ping.
1.4 - Data Alarms
Data Alarms are always associated with the serial input ports. The simplest data alarm to set up is
one that will activate when almost any string of data comes into the unit. This is useful on ports
that are specifically alarm ports. Full details on how to build alarms are available later in Chapter
5. The following are the steps to setup a Data Alarm:
1. At the command prompt, access the setup menu. Select “Alarm Definitions”, “Data Alarm 1
Settings”, and then “Setup Alarm Fields”. The following menu allows a user to define up to
16 data alarm fields to be used when scanning for alarm data. Below is an abbreviated
example of this menu:
Data-Link DL50 Data Alarm Field Definition Table
Start Length Name
A)
B)
...
O)
P)
2. Select field A. The menu in the following example will be displayed. The three options in
this menu are used to configure the starting position, length, and name of each data alarm
field:

I) Message []
J) Clear This Alarm Counter Now
8. Select Alarm Enable to toggle the value to ON.
9. Select Alarm Name and enter “Data Alarm 1”.
10. Select Actions and enter “T1” to cause this data alarm to send a trap to SNMP manager #1, as
configured in the SNMP managers menu.
11. Select Alarm Equation and enter “test_field=’test’”. This will cause an alarm to occur
any time the word “test” is received.
12. All other settings should remain at their default values for this test scenario.
13. Finally, the serial ports must be configured to monitor for data alarms. Return to the root of
the setup menu and select “Serial Settings” then “Serial Port 1 Settings”.
14. Toggle “Data Alarm Enable” to the value of 1. This causes the DL50 to monitor data
received on port 1 for alarms in data alarm family 1.
15. Press <CTRL> + C to return to the command processor.
Testing
Connect to the unit via serial connection on I/O 1 and enter the string “test” and then <ENTER>.
This should trigger the above data alarm, and an SNMP trap should be sent to trap manager #1. If
this is not the case, repeat the Network and Data Alarms settings.
Note: There will be a 30 second delay in alarming if the terminal emulator being used does not send a
LF with the CR. This may be circumvented by pressing <CTRL + J>.

2.3 - Front Panel
Figure 3: DL50 Front Panel
The front panel of the DL50 carries 3 push buttons and 22 LED indicators. This section will
explain the function of each of these indicators.
Note: The Next and Enter buttons on the front panel have no current functionality and are reserved for
future use.

Chapter 2 - What is a DL50?
Manual Rev. 1.01 Page 9
The Ethernet status is shown as three LEDs. The Link LED lights whenever an Ethernet 10BaseT
network link connection is found. The yellow TX LED lights briefly whenever an Ethernet frame
is being transmitted. The Active LED lights whenever a network connection, such as ftp, Telnet,
or a pass-through connection, is active. These LEDs can be used to see that a network cable
connection is made and when the DL50 transmits over the network.
I/O 1 has two LEDs associated with it. The left LED is a received data (RX) LED. The right LED
is a transmitted data (TX) LED. The TX LED is normally on and green when the unit is powered
up. The RX LED is off when no cable is connected to the serial port and green when a cable is
connected and no data transfer is taking place. When an RS-232 line is connected and idle, both
the TX and RX LEDs will be lit green. When data is transmitted, the TX LED quickly alternates
green and red. These LEDs can be used to verify that a cable is connected (the LED is lit) and that
data is being transmitted or received (the LEDs flicker between red and green). I/O 2 has a CTS2
LED in addition to pair of TX and RX LEDs. CTS2 lights when a clear to send signal is received
on I/O2.
The DL50 has five LEDs to indicate file full status. A solid lit LED indicates the database
percentage is at or over the value for that LED. A blinking percentage full LED indicates the
database has less than the amount indicated by that LED, but more than the previous.
The Power LED has two operational states. Normally the power LED is lit steadily, with a short
blink once every ten seconds. This ‘heartbeat’ signal indicates typical operation. The second state
occurs during the boot sequence, where it will blink once every second until the boot sequence is
complete and two beeps are heard.
2.4 - Back Panel
Serial Ports
Figure 4: Complete DL50 Back Panel
Both DB9 serial ports are DTE and male. This configuration is similar to that used on the COM
ports of an IBM-compatible PC. The following figure shows the pin configurations of these ports:

Omnitronix DL50 User’s Manual
Page 10
Figure 5: DL50 DB9 Pin Out
The two most important connections are the Receive Data line on pin 2 and the Signal Ground on
pin 5. When receiving serial data, these are the only two connections that the DL50 needs.
However, if either pass-through access to any connected serial devices or serial command line
access is required, then the transmitted data signal line on pin 3 must be connected as well.
Additionally, some equipment may require an RS-232 high signal on one or more of its signal
lines in order to transmit or accept data. Consult the manual for any connected equipment as
needed.
The DCE DB9 female cable end which mates with the serial port connectors of the DL50 will
often have a pair of screw-down cable locks. These cable locks should be used to assure a solid
connection of the cable with the DL50 serial port connectors.
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 Dipswitches to adjust these
settings.
Ethernet
The Ethernet 10BaseT connector is a standard RJ-45. This standard connector will connect the
DL50 to an Ethernet hub or switch.
Internal Modem
If a dialup modem is installed, an RJ-11 (typical U.S. phone) connector is used. A POTS (analog)
dialup phone line is inserted into this connector. Depending on the model of modem installed, one
or two RJ-11 connectors may be present on the back panel. In the latter case, one will be labeled
‘phone’ and the other ‘line’. Connect the dialup phone line to the connector labeled ‘line’.
The modem installed within this unit is FCC certified. For further information, consult Appendix
B, or the serial number label on the bottom of the DL50.
Dipswitches
The back of the DL50 is equipped with two banks of eight Dipswitches:

Chapter 2 - What is a DL50?
Manual Rev. 1.01 Page 11
Figure 6: Dipswitch Orientation
Please refer to the following for the functionality of each switch:
• Switches A1 through A3 and B1 through B3 configure baud rate for I/O1 and I/O 2,
respectively (see table below)
• Switches A4 through A6 and B4 through B6 configure word length, parity, and stop bits for
I/O1 and I/O 2, respectively (see table below)
• Switch A7 is reserved and is to remain off at all times
• Switch A8 is reserved for future use
• Switches B7 and B8 determine the operating mode of I/O 2 (see table below for details)
The following table outlines the functionality of Dipswitches B1 through B6 in switching the baud
rate and port settings of I/O 2.
Baud Rate SW1 SW2 SW3 Word, Parity, Stop SW4 SW5 SW6

2.5 - Functionality Overview
The DL50 is designed to perform several functions key to the Data-Link family while offering
greater value to users who do not need the full range of functionality offered by the Data-Link
DL880 or DL100. The features of the DL50 are covered in the following subtopics.

Omnitronix DL50 User’s Manual
Page 12
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.

Chapter 2 - What is a DL50?
Manual Rev. 1.01 Page 13
2.6 - Security
Callback Security
Omnitronix cares deeply about the security of the data within and devices connected to our
products. To that end, there are several key security features available on the DL50:
Callback security allows an administrator to strictly limit the phone numbers allowed access to the
unit. This is accomplished via an exclusive set of outbound phone numbers that have access.
When a user attempts to connect to the unit via modem, they must enter a password. If the
password is valid, the unit disconnects the call and then calls a phone number predefined for that
password. The computer at the callback number is then issued the same password prompt. This
method of callback security puts the system administrator in charge of which modems are allowed
access to the device.
No Network Proxy
The DL50 does not perform any sort of network proxy action. At no time is a user connected via
any means able to directly interact with other devices on the same network. The only outbound
network access the DL50 allows is PING and FTP push.
Password Protection
The DL50 has two different access levels available: user and administrator. The unit allows for up
to two different user-level passwords. Each of these passwords allows only a limited set of
commands and no access to the setup menu. All user-level passwords can be associated with a
security callback number, if desired. There is only one system administrator password. This
password allows for unfettered access to all of the features of the unit, so this password should be
kept very secure.
Access to any of the following features can be controlled by a password:
• Serial, Telnet, or modem command mode
• Command mode system administrator
• Pass-through port access
• Internal FTP server
Using the USER or SUPER commands allow a person already logged on to the device to switch
between user and system administrator privileges. The USER command switches to user level
with no prompt, while SUPER requires the sys admin password.
Further security is gained by character blocking on password inputs. Asterisks are placed on the
screen in place of each character typed. In order for this security feature to work properly, both
the DL50 and the terminal used to access it need to be configured for full duplex (no local echo).

Getting Connected
3.1 - Power Up Sequence
On startup, the DL50 goes through a boot up process and exhibits the following functionality:
• Internal buzzer beeps once
• The power LED flashes once each second for about 15 seconds
• Modem Active LED lights for 5 seconds if a modem is installed
• Ethernet Active LED lights for 5 seconds if an Ethernet interface is installed
• Internal buzzer beeps twice
• Power LED will begin to blink once every 10 seconds as a ‘heartbeat’ for the DL50
3.2 - Methods of Connecting
Connecting Via Serial Port
Connect to I/O 2 with the 6’ Female DB9 to Female DB9 null modem cable. Ensure that
Dipswitches B7 and B8 are off in order to enable command mode. By default, serial port
command processor access is not password protected. Once connected, the command line is
available in system administrator mode. The following table contains the default passwords for
the DL50.
Mode Password
User 1 SMDR
User 2 USER2
I/O 1 Real-Time Socket ACCESS1
I/O 2 Real-Time Socket ACCESS2
Alarms file Real-Time Socket ACCESSA
System administrator SUPER
Connecting Via Modem
Upon first dialing into the DL50, a user is presented with the unit answer string. By default, this
string is “Data-Link”. This string can be changed to indicate the specific application of this
device.
The previous table contains the default passwords configured on the DL50. It is recommended
that a system administrator change these passwords and keep them recorded in a secure location
thereafter.

Omnitronix DL50 User’s Manual
Page 16
Note: When a specific password is defined as blank or null, access via the specific method that password
protects is disabled.
After entering an appropriate password, the DL50 will present an acknowledgement and the user
will be connected to the appropriate command processor. Once connected to the Command
Processor, the user has the same capabilities as if connected via serial port.
Connecting Via Telnet
Before using the DL50 via Ethernet for the first time, it is necessary to assign an IP address via
serial or modem connection. For typical command mode actions, TCP port 23 will be used.
Following is a table of the other TCP ports allowed on the DL50 and their functions.
PORT Function
21 Internal FTP server, reserved for future use.
23 Telnet to local command port.
2001 Telnet to local command port.
210nThe ncorresponds to the serial port number to connect a pass-through
connection to. For example, port 2101 connects to I/O1.
220n The ncorresponds the serial port number with which to perform a real-time
socket connection. For example, 2202 connects to FILE2.
2205 Telnet to alarms file real-time socket.
Because the same connection processes are used with both Telnet and modem connections, it is
possible to follow the same steps outlined above in the Connecting via Modem section when
connecting with Telnet.
3.3 - The Status Screen
The DL50 status screen is this unit’s one-stop informational source. Most of the information that
a user would need to know about the unit is available through this display. This section outlines
this data and highlights why it is useful.

The status screen in the DL50 is dynamically created according to the configuration of each
particular unit. Because of this, the above example may not be identical to another.
Unit ID is the identifier assigned to each DL50 by the end user.
Date and Time are displayed for user informational purposes.
Memory indicates the amount of data-ready memory installed on the DL50.
% Full indicates the percent of the memory installed that is currently occupied by serial port data
and alarm records.
Modem and Network both indicate whether or not that hardware is installed in the DL50. This
status is marked by a YES or NONE.
If a network interface is installed, the IP Add and MAC Add display the appropriate address
values. The MAC address is displayed for informational purposes and cannot be changed.
Unit Serial # is the factory-assigned, unique serial number for each individual unit.
% Full Alarm / No Data Alarm indicates the current ON/OFF status of the 80% full alarm and
no data alarms 1 and 2, respectively.
Release Mode indicates the current command processor data release method. This can be line,
CBB, or Xmodem.
Duplex controls the echo settings for the command processor. Full duplex causes the DL50 to
echo all characters sent to the remote device. Half duplex turns off character echo.
