Model 244EC Configuration Interface

Screen Conventions

The Models 244EH and 244ER Configuration Software follows the Microsoft Windows screen conventions with the following exception: Configuration parameters change color to indicate fields where information has changed. Before placing a new transmitter into service, or before returning a transmitter to service after changing configuration information, verify that the values in the fields that have been changed reflect the correct configuration parameters for your application. For example, if you change the Sensor Type field to PT100– Alpha 392, the Number of Wires, Units, 4 mA Point, and 20 mA Point fields all change to reflect the default PT100–Alpha 392 sensor values. Verify all information before placing the transmitter into service.

The Model 244EC Configuration Interface is a portable, self-contained link between your PC and a Model 244. The Model 244EC connects to a PC serial port with a standard 9-pin interconnecting plug and connects to a transmitter with two MINIGRABBER™ clips.

The Model 244EC will also operate using a wall power adapter or a single replaceable 9-volt battery.

Setting Up the Model 244EC Configuration Interface

All necessary power is provided through the configuration leads from the Model 244EC to the transmitter. The sensor does not need to be disconnected in order to configure the transmitter.

To set up the Model 244EC Configuration Interface and prepare it for use, refer to Figure 2-10 on page 2-12and follow the procedure described below.

1.Install the 9-volt battery in the Model 244EC. Be sure the power switch remains in the “OFF” position.

2.Attach the ribbon cable from the Model 244EC to the serial port of your PC using the 9-pin interconnecting plug. If your PC has a 25-pin serial port, you will need a 25-pin to 9-pin adapter to accommodate the connection.

NOTE

It is not necessary to power down your PC before you attach the Model 244EC. However, if you are using a desktop model, you may wish to power down to reduce the risk of electric shock or computer damage.

3.Attach the configuration leads to the Model 244EC using the banana jacks provided. Be sure to observe proper polarity—attach the red lead to the positive (+) jack on the Model 244EC and the black lead to the negative (–) jack.

4.Attach the configuration leads to the configuration terminals (labeled “PROG”) on the transmitter using the MINIGRABBER clips provided. Be sure to observe proper polarity—attach the red lead to the positive (+) terminal on the transmitter and the black lead to the negative (–) terminal.
