Page 7: Installation
When mounted in an optional NEMA-4X weatherproof enclosure, the OMA-D560 can be used in damp or dusty environments or placed outdoors. If the outputs of the OMA-D560 are used to switch voltages in excess of 30 volts, the unit must be mounted in an approved electrical equipment enclosure. -
Page 8: Standard Phone Lines
The OMA-D560 will also work with North American analog cellular phones equipped with a dial-tone adapter. Contact technical support for details. Connecting a Power Source The OMA-D560 is factory configured to operate on 110 VAC 50/60 Hz OR 220 VAC 50/60 Hz. It can also operate from 12 VDC. AC Operation Plug the OMA-D560’s power cord into a properly grounded (three-wire) electrical outlet. -
Page 9: Disabling The Backup Battery
Test the battery at least once per year by removing the OMA-D560’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. - Page 10 DIP switch. Attach your 4-20 mA sensor to the input screw terminals. Keep in mind that the OMA-D560’s internal shunt resistor is referenced to common and that no other device in the loop can be referenced to ground. If it is impossible to isolate the other devices in the loop, a signal isolator may be required.

Page 11: Connecting The Outputs
Contact technical support for assistance. Connecting the Outputs The OMA-D560 has four outputs that can be controlled remotely or automatically in response to alarm conditions or input parameters. The control capabilities of these outputs are described in the “Control” section of this manual. -
Page 12: Communications
Data, voice or pager? It’s your decision! The OMA-D560 system can communicate over a standard phone line with a computer or pager. It also offers a powerful, easy-to-use voice mode for ready-access to information from your equipment anytime, from any standard telephone. -
Page 13: Modem Mode
To end a voice mode session, simply type BYE#. Modem Mode You can communicate with the OMA-D560 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 &... -

The OMA-D560 will prompt you to enter a security code. You must enter a valid security code within 30 seconds or the OMA-D560 will terminate the connection. If you don’t know the security code, try the factory default security code, “11111111”... -
Page 15: Commissioning Checklist
Configure the Inputs The OMA-D560 accepts a variety of different input types. Use the INP S command to instruct the OMA-D560 as to how to interpret and report this input data (refer to the Command Reference section). Configure the Data Logger The OMA-D560’s data logger can be configured to take periodic “snapshots”... -
Page 16: Configuring The Alarm Dialer
The OMA-D560 system continually monitors all inputs for alarm set-points that have been violated. If a set- point has been exceeded for a designated period of response time, the OMA-D560 system recognizes this as the existence of an alarm condition. -
Page 17: Operation
Operation Reports The OMA-D560 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 communication session without the need to enter a pass code. Reports can be accessed by any security level. -

None Time: 02/05/00 12:54:56 Alarm report. The OMA-D560 system will report all alarms and give you the option to acknowledge any unacknowledged alarms. Phone Directory Report To get a report of the designated dial-out phone names and numbers, type PHO R at the command prompt. -
Page 19: Alarm Handling
Alarm Handling The OMA-D560 system constantly monitors all inputs to determine if alarm set-points have been violated. If a set- point 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. -
Page 20: Output Control
Output Control The OMA-D560 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. Configuring an Output Each output has several parameters that define how and when they will activate. To check or modify these parameters, type OUT S and select an output. -
Page 21: Control Mode
“on” and “off” set-points on a designated input channel. In alarm mode, an output is controlled by the alarm status of the OMA-D560. You can mix or match control mode settings among the four output channels. -

232 port or via telephone. Configuring the Data Logger Whenever a system or log event occurs, the OMA-D560 system will write to memory a time-stamped record of parameters. To check or modify the data logging control parameters, type LOG S. -
Page 24: Clear
When the high-resolution log is disabled, only one byte per selected input is logged. Data Extraction and Analysis Data from the OMA-D560 system can be downloaded in a readable format or in a file format compatible with most spreadsheet and data analysis programs. Select the desired format with the LOG O command. -
Page 25: Compressed Ascii
Downloads much faster than uncompressed ASCII. Compressed XMODEM The most reliable way to transfer large amounts of data from the OMA-D560 system to a personal computer is with the XMODEM file transfer protocol. Many communications programs (such as Hyperterminal) support the XMODEM protocol. -

COMMAND>BYE COM (Communications Gateway) The OMA-D560 system provides a data path between its phone line modem and its local RS-232 port, allowing you to talk “through” the OMA-D560 system to an external computer or system. Help with the COM command Type COM at the command prompt and the OMA-D560 system will return a list of valid communications commands and related instructions. -
Page 28: Open Communications Gateway
For example: If you have a OMA-D560 system operating its modem at 33.6 kbps and its RS-232 at 115 kbps you must make sure that the device attached to the RS-232 port does not transmit data at a sustained rate of 115kbps. -
Page 29: Cnt (Pulse Counter)
CNT (Pulse Counter) The OMA-D560 system allows pulse counting on all eight analog inputs. It uses two commands in data mode, CNT R, to display all eight counters, and CNT O, to clear individual counters. The maximum transition rate is 100 state transitions/second (50 Hz signal = 50 counts/second) with no two transitions occurring within less than 10ms of each other. -
Page 30: Hlp
Each input has separate alarm and control set points. The control set points can be used to automatically control output devices (see OUT S). Help with the INP command Type INP at the command prompt and the OMA-D560 system will return a list of valid input commands and related instructions. OMEGA ENGINEERING, INC. -
Page 31: Input Status Report
Input Damping Input damping causes the OMA-D560 to react slowly to a rapidly changing input. For example, if temperature were being monitored and the temperature probe was moved from an ice bath to a hot water bath, a damped input would show a gradual change in temperature every 10 to 20 seconds, rather than an instantaneous change. - Page 32 7 = Output ON Setpoint 8 = Calibration 0 = Previous Menu Choose a Number>1 ENTER AN 8 CHARACTER LABEL NAME, TYPE "=HIDE=" TO REMOVE THIS ITEM FROM ALL REPORTS, OR PRESS ENTER FOR A LIST OF SPECIAL LABELS. >Outside Air OMEGA ENGINEERING, INC.
- Page 33 If the input value falls below the low alarm set point or above the high alarm set point for a defined period of time, the OMA-D560 system will recognize an alarm condition. In the case of a dry contact, if the input state equals the configured alarm state then an alarm condition is triggered.

A second menu will be given, listing all parameters associated with that input. Choose "Calibration". The OMA-D560 system will display the measured value of the input and ask you to enter the actual value. When you do, a calibration offset will be calculated and stored in the OMA-D560 system's memory. -
