1. 1. About the OMR Analog Input Modules

The OMR provides a series of analog input modules which can sense the ana log signal or to control the remote devices. The basic features of each module are shown here.

• OMR-6011/D : multi-functions high gain analog input module

• OMR-6012/D : multi-functions analog input module

• OMR-6013 : 3 channels RTD input module

• OMR-6014D:Analog (Transmitter) input module with LED display

• OMR-6017 : 8 channels analog input module

• OMR-6018 : 8 channels thermocouple input module

V The models with an extended D have the same command set and specification as without D, except the D version has a 5

1/2 LED Display.

1. 2. Overview of OMR-6011/D

What is OMR-6011/D ?

OMR-6011/D is a multi-functions analog input module with cold junction compensation (CJC). The maximum input voltage range of analog input channel is ±2.5V. The high gain feature allows very small full range of ±15mV. To measure temperature by directly connect the thermal couple is possible because of using the CJC inside and the high gain feature.

The voltage range of the ADC can be set according to different types of thermal couple. The ADC can be calibrated by programming without handy adjustment. This feature insure the best performance under different environment.

The module provides the analog signal monitor or the alarm function. The high and low bound of the alarm limit can be se t by programming. The alarm status can be sent to digital output channels if this function is ON. The supervisor of a factory can ‘see’ or ‘hear’ the alarm if the digital output channel control a real alarm device. The two digital output channels can be set for general purpose use if the alarm is disabled.

Introduction 1-1

For example, connecting relay devices to DO channels, the OMR-6011/D can be used to control the high power devices. The module provides another one digital input channel. This can be used for general purpose such as monitor digital

signal, or be used as input of the event counter.

2. Initialization & Installation

2. 1. Software Installation

1. If you have already installed “OMR Administration” then skip other steps.

2. Backup your software diskette.

3. Insert “OMR Administration” disc into CD-ROM:

4. Change drive to the path of CD-ROM. For example, your drive of CD-ROM is F:, then change the drive to F:

5. Find the setup of OMR Administration and run it.

6. Please follow the steps of setup program then you can successful to install the nudism Administration.

2. 2. Initializing a Brand New Module

Objective of Initializing a Brand New OMR

All OMR modules, except OMR -6520 and OMR -6510, in a RS-485 network must have an unique address ID. Every brand new OMR has a factory default setting as following:

• Address ID is 01.

• Baud rate is 9600 bps

• Check-sum disable

• Host Watchdog timer is disable

Therefore, to configure the brand new OMR before using is necessary to avoid conflicting address. The baud rate may also be changed according to user‘s requirements.

The initialization procedures of a brand new OMR are shown in the following sections. The procedures are applicable for initializing OMR-6011/D, OMR-6012/D, OMR-6013, OMR-6014D, OMR-6017, and OMR-6018.

Initialization & Installation 2-1

Default State

The OMR modules must be set at Default State when you want to change the default settings, including the ID address, baud rate, check-sum status etc. All OMR modules have an special pin labeled as DEFAULT*. The module will be in Default State if the Default*1 pin is shorted to ground when power ON. Under this state, the default configuration is set as following:

• Address ID is 00.

• Baud rate is 9600 bps.

• Check-sum disable.

• Watchdog timer is disable.

Therefore, the configuration of the host and the module can be easily set identically and initializing a module will be possible no matter what configuration is set under operating state.

Initialization Equipments

• Host computer with an RS-232 port.

• An installed RS-485 module (OMR-6520) with 9600 baud rate.

• The brand new OMR module

• Power supply (+10 VDC to +30 VDC) for OMR modules

• Administration utility software

Note1: Never Connect the DRFAULT* pin to Vs or power source just left it open or wired to GND.

Initialization Procedure

Local Power Supply

New OMR

OMR-6520

1. Power off the host computer and the installed OMR-6520. Be sure of the baud rate of the OMR-6520 is 9600 bps.

2. Connect a brand new OMR module with the RS-485. Set the module in Default State by shorting the DEFAULT* pin. Refer to Figure 2.1 for detailed wiring.

3. Power on the host computer.

4. Power on the power supply for OMR modules.

5. Use the OMR Administration utility to configure the address ID, Baud rate and check-sum status of the module.

2. 3. Install a New OMR to a Existing Network

Equipments for Install a New Module

• A existing OMR network

• New OMR modules.

• Power supply (+10 to +30 VDC).

Installing Procedures

1. Configure the new OMR module according to the initialization procedures in section 2.2.

2. The baud rate and check-sum status of the new module must be identity with the existing RS-485 network. The address ID must not be conflict with other OMR modules on the network.

3. Power off the OMR power supply of the existing RS-485 network.

4. Power off the host computer.

5. Wire the power lines for the new OMR with the existing network. Be careful about the signal polarity as wiring.

6. Wire the RS-485 data lines for the new OMR with the existing network. Be careful about the signal polarity as wiring.

7. Wire to the input or output devices. Refer to section 2.4 for illustrations.

8. Power on the host computer.

9. Power on the OMR local power supply.

10. Use the OMR administration utility to check entire network.
