A “home” for your OMA-D570

Your new OMA-D570 should be located in a convenient location close to the conditions being monitored - in a warehouse, basement, utility closet or other work area, mounted on a wall, or mounted inside an equipment cabinet.

When mounted in an optional NEMA-4X weatherproof enclosure, the OMA-D570 can be used in damp or dusty environments or placed outdoors.

If the outputs of the OMA-D570 are used to switch voltages in excess of 30 volts, the unit must be mounted in an approved electrical equipment enclosure.

Connecting a Phone Line

The OMA-D570 is designed to work on most public phone systems found throughout the world. It will also work on most office PBX phone systems. With optional equipment, it will also work on cellular phone systems and with low-orbiting satellites.

www.omega.com

n Standard Phone Lines

For your convenience, the OMA-D570 has a dual phone jack. Plug a telephone line into one of the OMAD570’s phone jacks. You can attach a standard telephone into the other jack. It is recommended that you use this standard telephone to check the phone line for dial tone and the ability to make incoming and outgoing phone calls.

n Cellular Phones

The OMA-D570 will also work with North American analog cellular phones equipped with a dial-tone adapter. Support for GSM and PCS cellular phones is planned for the future. Contact technical support for details.

n Low-Orbiting Satellites

The OMA-D570 works with an optional satellite transceiver capable of providing cost-effective communication from virtually any location on Earth. Contact technical support for details.

Connecting a Power Source

The OMA-D570 is factory configured to operate on 110 VAC 50/60 Hz OR 220 VAC 50/60 Hz. It can also operate from 12 VDC.

n AC Operation

Plug the OMA-D570’s power cord into a properly grounded (three-wire) electrical outlet. The power required by the OMA-D570 is 20 watts plus the wattage of the load (if any) attached to the “AC Switched Output” connector.

n DC Operation

Connect the positive lead of a 9 to 15 VDC source to the “DC IN” terminal and connect the negative lead to the “Common” terminal.

IMPORTANT: When using DC power, the OMA-D570’s AC power cord MUST be disconnected AND its backup battery MUST be disabled by removing the jumper from between the “BATT OUT” and “DC IN” terminals.

n Solar Operation

The OMA-D570 can be powered by a properly sized solar panel. Contact technical support for details.

Backup Battery

The OMA-D570 system has an internal rechargeable battery that maintains full operation in the event of a power outage. This battery must be enabled when the unit is put into service and disabled when taken out of service. All information programmed into the OMA-D570 system will be retained whether or not the battery is connected to the system.

NOTE: An auxiliary DC power output on the OMA-D570 system can be used to power external sensors and accessories. It provides 12 volts DC (nominal) at up to 200 mA. This power is taken from the OMA-D570 system’s backup battery and will provide uninterruptible power, even during a power outage.

Omega Engineering, Inc.

n Enabling the Backup Battery

Attach the shorting clip (included with the unit) between the “BATT OUT” and “DC IN” terminals. If the shorting clip is lost, a short length of wire can be used. Once enabled, the battery will require up to 24 hours to fully charge.

n Disabling the Backup Battery

To disable the backup battery, remove the shorting clip from between the “BATT OUT” and “DC IN” terminals.

n Testing the Backup Battery

When operating from AC power, the power light on the front panel of the OMA-D570 system is green. When operating from battery, the power light is red.

Test the battery at least once per year by removing the OMA-D570’s AC power source for 10 to 15 minutes and verifying that the power light changes to red and that the unit responds to an incoming phone call.

Attaching the Inputs

The OMA-D570 system supports eight universal inputs that can accept a variety of input types. Input expansion modules are available to increase the monitoring capability of the OMA-D570 to 32 inputs (see Input Expansion Modules).

Inputs 1 through 4 are factory pre-configured to accept 4-20 mA signals while inputs 5 through 8 are factory preconfigured to accept dry-contact signals. It is easy to re-configure an input to accept 4-20 mA, 0-5 VDC, thermistor, logic-level, dry-contact or other signal types in any combination.

n DIP Switch Settings

Removing the input connector reveals two banks of DIP switches as illustrated in the figure below. Each bank has eight switches labeled 1 through 8 corresponding to inputs 1 through 8. The upper bank controls 200-ohm shunt resistors (required for current monitoring applications) while the bottom bank controls pull-up resistors (required for temperature monitoring and dry-contact applications.

Omega Engineering, Inc.

Communications

This section describes the procedure for establishing communication with the OMA-D570 system. It includes details on how to use the RS-232 port for local or satellite communication, a phone line for data, voice, pager and fax communication, and how to put data into the web.

Using a Phone Line

Data, voice, pager or fax? It’s your decision!

The OMA-D570 system can communicate over a standard phone line with a computer, pager, or facsimile machine. It also offers a powerful, easy-to-use voice mode for ready-access to information from your equipment anytime, from any standard telephone.

The data mode will allow you to review inputs, set up and reconfigure any OMA-D570 system from a remote location, retrieve stored information, and perform diagnostics from your PC.

The voice mode offers the convenience of inquiry into condition status from any standard telephone, and provides a high-quality, clear, consistent voice without the need for set up, programming, or recording.

The OMA-D570 can also be programmed to call a facsimile machine at predetermined times and deliver a concise status report.

IMPORTANT

n Voice Mode

Information intended exclusively for voice-mode users is

highlighted in this guide by a telephone icon and use of this

different type face

' The OMA-D570 will respond to your call by generating a "bong" sound, followed by a few

seconds of silence. If you press the # key on your touch-tone phone during the time of silence, the system will immediately switch to voice mode. Otherwise, the system will begin to generate a carrier tone − indicating that the system is attempting to communicate with a data terminal. The tone will eventually stop after a few seconds and the OMA-D570 will again switch to voice mode and speak in a synthesized voice:

“Hello, this is telephone number five, five, five, one, two, one, two. Enter security code.”

Enter your eight-digit security code on the touch-tone keypad (initially set at the factory to “1, 1, 1, 1, 1, 1, 1, 1). You do not have to press # after the eight digits are entered. The OMA-D570 system will respond “OK.”

www.omega.com

The voice mode of the OMA-D570 system utilizes a built-in voice enunciator that responds to commands entered from any standard push-button tone-dialing telephone. You enter command codes from the telephone keypad and response messages are spoken in English.

Voice Mode commands consist of a three-letter code followed by either the # or * key. The following commands are available in the Voice Mode:

ALM# = Alarm acknowledge BYE# = Terminate on-line session INP# = Input report OUT# = Output report TIM# = System time report VOX# = Custom Voice Phrase Report

For example, typing INP# initiates an INPut report:

I N P

GHI4MNO6PQR

To end a voice mode session, simply type BYE#.

n Modem Mode

You can communicate with the OMA-D570 system using a PC with a modem and any popular communications program having terminal emulation capability. One such communications program is “Hyperterminal”, a program that is included free with the Microsoft Windows 95, 98, 2000 & NT operating systems.

Since HyperTerminal is used throughout this manual to illustrate data mode operation, detailed instructions on its use are included in this section.

Defining a HyperTerminal Connection

To use HyperTerminal, you must first define a few parameters including the phone number of the OMA-D570. To start HyperTerminal, click Start, and then click Programs, Accessories and Hyperterminal. Look for an icon labeled HyperTerminal or Hypertrm.exe and click on it.

In the Connect Description box, type a name for the connection, choose an icon, then click OK. In the Connect To box, enter the country/region, area code and phone number of the unit to be called and

choose your computer's modem from the Connect Using list (Note: if your modem is not listed in the Connect Using list, it may not be installed properly). Click OK.

Click the Dialing Properties button to view information about the location of your computer. You may not have to make any changes to this box, but make sure the information is correct. If your modem is attached to an office phone system, you may need to enter a code (such as “9”) to access an outside line. Verify that the Number to be dialed in the lower left corner of the box appears exactly as it would if you were to dial the OMA-D570 from your telephone. It must not include any extraneous numbers. Click OK.

In the Connect box, click Cancel. It is now time to save your settings and exit the program. On the HyperTerminal menu bar, select File, Save and then File, Exit.

Omega Engineering, Inc.

Establishing Communication

Once you’ve defined a connection to your OMA-D570, establishing communications with it is as simple as clicking on an icon.

Start HyperTerminal by clicking Start, Programs, Accessories and Hyperterminal. Look for the OMA-D570 connection that you've created and click on it.

When HyperTerminal starts, you will see the connection information in the Connect box. Click Dial. You may hear dialing tones or pulses followed by a “ring” sound, followed by modem tones.

When the OMA-D570 answers, it will prompt you to enter a security code. You must enter a valid security code within 30 seconds or the OMA-D570 will terminate the connection. If you don’t know the security code, try the factory default security code, “11111111” (eight ones) followed by Enter.

Once you have gained access, you can enter commands and the OMA-D570 will respond. If you press Enter at the command prompt, you’ll get a complete listing of commands. The most common commands are INP R (input status report), ALM R (alarm report) and SEC R (security report).

If HyperTerminal fails to connect, re-check your settings (especially Dialing Properties settings) and try again. Once a connection is established, the Connect box will close and the main HyperTerminal screen will become active.

In the following sections of this manual are step-by-step procedures that will help you prepare the OMA-D570 system to work for you - describing how to designate individuals you want to receive alarm messages, set low and high alarm set-points, etc.

The commands to access the system are simple three-letter codes (e.g. INP = input, ALM = alarm, PHO = telephone), generally followed by a fourth letter (e.g. R = report, S = set). The system will automatically insert a blank space between the third and fourth characters.

If an incorrect command is entered, you will receive an “Invalid Command” message. You may enter a command whenever the “COMMAND>” prompt is displayed.

n Fax Mode

The OMA-D570 system can send alarm reports directly to a fax machine. Input status reports can also be sent to a fax machine on a scheduled basis.

Internet Access

An optional internet service is available that will generate detailed daily reports based on information collected by your OMA-D570 and post those reports to a website. Contact customer service for additional information.

Using the RS-232 Port

Attach a “straight-through” serial cable from your PC’s serial port to the RS-232 port on the side panel of the OMA-D570 system (next to the phone connector).

Follow the procedure outlined in “Modem Mode” (above) to define a HyperTerminal connection, substituting the appropriate COM port for the modem in the Connect Using list then click Configure and enter the following settings:

Commissioning Checklist

The commissioning process tailors the OMA-D570 system to your unique remote monitoring application. This section outlines the minimal commissioning tasks required for many applications. Complete details relating to the commands mentioned in this section are discussed in further detail in the COMMAND REFERENCE section later in this manual.

IMPORTANT: The OMA-D570 remote monitoring system has many time and money-saving capabilities that can only be realized after having a thorough working knowledge of all of the commands described in the COMMAND

REFERENCE section in this manual.

R Identify the System

The OMA-D570 has several programmable fields to help identify it in both voice and data modes. These fields include “site name” and “code number” (for data mode identification) and “unit phone number” (for voice mode identification).

The information that you enter in these fields will not affect the operation of the unit but will help you manage information from your remote sites.

Use the SEC S command to enter system identification information.

R Configure the Inputs

The OMA-D570 accepts a variety of different input types. Use the INP S command to instruct the OMA-D570 as to how to interpret and report this input data.

R Configure the Data Logger

The OMA-D570’s data logger can be configured to take periodic “snapshots” of designated inputs and/or record system events and alarm conditions.

Use the INP S command to designate the inputs to be recorded and the LOG S command to set logging parameters.

www.omega.com

R Configuring the Alarm Dialer

The OMA-D570 system continually monitors all inputs for alarm set-points that have been violated. If a setpoint has been exceeded for a designated period of response time, the OMA-D570 system recognizes this as the existence of an alarm condition.

It will send the message to up to eight designated telephone numbers anywhere on or off site and at any time. If the calls are unanswered, the OMA-D570 system will wait a pre-set length of time and perform the complete dial-out sequence again.

The alarm dial-out sequence will continue − even if the alarm condition has cleared − until the alarm has been externally acknowledged.

To fully configure the alarm dialer, use the INP S command to set the alarm set-points and the PHO O command to program the dialing directory.

Omega Engineering, Inc.

Operation

Reports

The OMA-D570 generates a variety of concise text reports. Each report is updated just prior to generation and is time-stamped. An auto-report feature, when enabled, produces an input report at the beginning of each communications session without the need to enter a pass code. Reports can be accessed by any security level.

n Input Report

Alarm Handling

The OMA-D570 system constantly monitors all inputs to determine if alarm set-points have been violated. If a setpoint has been violated for a specified amount of response time, an alarm condition exists.

This alarm condition will continue until the input has returned to normal and has been externally acknowledged. When an alarm occurs and the response time has expired, the OMA-D570 system will begin its dial-out sequence.

The OMA-D570 system can deliver an alarm in voice, fax or data mode. The OMA-D570 system will dial each number in succession. If the alarm is not acknowledged, the OMA-D570

system will wait a specified alarm dial-out interval and then start another dial-out sequence with the same alarm message.

Alarms can be acknowledged in either data or voice mode. There are two classes of alarms Active acknowledged alarms: The input continues to violate an alarm set-point but an operator has acknowledged

the condition. The OMA-D570 system continues to recognize the alarm condition but will not attempt to make an outgoing phone call.

Unacknowledged alarms: Any alarms, which have not been acknowledged. An unacknowledged alarm initiates an alarm dial-out sequence.

n Alarm Dial-Out Reminder

An optional feature of the OMA-D570 system will enable the dial-out sequence even after an alarm has been acknowledged.

When an alarm occurs, the OMA-D570 system will dial out to all phone numbers in its phone number list once or until it is acknowledged. It will then wait the dial-out interval, as specified in the ALM S menu.

If the re-dial after acknowledgment (in ALM S) is enabled, the OMA-D570 system will dial out again if there are any unacknowledged or acknowledged alarms present.

If disabled, it will re-dial only if there are unacknowledged alarms. When re-dialing, the system will dial every number in the phone number list or until it is acknowledged.

n Responding to an Alarm Message - Voice Mode

' The OMA-D570 system will call the preprogrammed numbers when an alarm condition is

recognized. When the phone is answered, the OMA-D570 system will repeat the alarm message up to six times:

“Hello, this is telephone number one two three four five six seven. Alert condition exists.”

Recipients of such calls should press and hold any keypad button for one to two seconds. The OMA-D570 system will respond with the following message:

“OK. Enter security code.”

When a correct security code has been entered, the OMA-D570 System will acknowledge it, saying, “Yes.” You can now enter INP R to learn the cause of the input alarm condition and enter ALM# to acknowledge receipt of the alarm message.

The alarm can be acknowledged in either data or voice mode.

' To acknowledge an alarm and prevent the OMA-D570 system from dialing out again until

new alarm conditions exist, type ALM#.

n Responding to an Alarm Message - Data Mode (local)

For local response, an indicator on the front panel of the OMA-D570 system will flash if there are any unacknowledged alarms. An ALARM CANCEL switch enables alarms to be canceled from the front panel.

The indicator will remain on continuously if there are acknowledged alarms.

Control

The OMA-D570 includes a straightforward output controller that enables you to activate or reset equipment remotely on demand or automatically in response to input set-points or alarm conditions.

Output Control Modes

The output controller has several modes of operation that can be grouped into three categories: Manual, Automatic and Alarm. In manual mode, an output is controlled by commands issued by the user. In automatic mode, an output is controlled by “on” and “off” set-points on a designated input channel. In alarm mode, an output is controlled by the alarm status of the OMA-D570. You can mix or match control mode settings among the four output channels.

The output control mode settings can be found in the OUT S menu.

AVAILABLE CHOICES

----------------1 = Manual 2 = Automatic 3 = Automatic Day 4 = Automatic Night 5 = Close on Present Alarms 6 = Open on Present Alarms 7 = Close on Unacknowledged Alarms

n Manual

Manual control permits an operator to remotely control the on/off state of the four output relays. Use the OUT O command and select the channel you want to control then use the spacebar to manually toggle

the output “on” or “off”.

' The on/off state of the output is controlled by the operator with the On1# and On0#

commands. Entering On1# turns output “n” ON and On0# turns output “n” OFF, where “n” is the desired output number (1-4).

EXAMPLE: To turn output three OFF, press “0”, “3”, “0”, “#” on the phone keypad. To turn output three ON, press “0”, “3”, “1”, “#” on the phone keypad.
