The details of how to access Properties/Methods/Events varies between development platforms. Details of how it works in some

of the most popular platforms is illustrated in the samples included with the RF Utilities CD or available for download from our

website at:

Properties – ActiveX Object

Properties are the various configuration variables used by the WDterm control. They are directly assignable in your application

(e.g. "WDterm.ActiveTerminal = 5") and can be set in your development environment’s object browser.

Important: Except for ActiveTerminal and Quiet, all properties require the serial port to be "closed" before they can be changed.

Use the CloseDevice method before setting properties and then call OpenDevice to re-open the serial port.

Note that your development environment may show more properties for the WDterm control than are listed here. This is normal.

You may ignore properties you see that are not listed here.

ActiveTerminal

Valid values: 0 -63

Definition: This is the terminal ID (0-63) to which method call instructions are directed.

ComDeviceName

Valid values: COM1-COM16

Definition: This is the serial port that this instance of the control will use. If you have more than one base station,

drop in another WDterm control and set its ComDeviceName for your other COM port(s).

ComBaudValue

Valid values: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200

Definition: This is the serial port speed setting and must match the base station setting.

ComParity

Valid values: None, Even, Odd.

Definition: This is a serial port setting and must match the base station setting. WDterm may allow other settings

but those listed here are the only ones compatible with current version base stations.

ComDataBits

Valid values: 7, 8

Definition: This is a serial port setting and must match the base station setting. WDterm may allow other settings but

those listed here are the only ones compatible with current version base stations.

ComStopBits

Valid values: 1, 2

Definition: This is a serial port setting and must match the base station setting. WDterm may allow other settings but

those listed here are the only ones compatible with current version base stations.

Quiet

Valid values: True, False

Definition: If Quiet is set to True then any status and error message generated by WDterm will be suppressed.

Methods – ActiveX Object

Methods are commands that you issue to the WDterm control. All of the "Inputxxx" commands cause the terminal to wait for

operator input.

Note that your development environment may show more available methods for the WDterm control than are listed here. This is

normal. You may ignore methods you see that are not listed here.

Important: When your application starts up, the serial port is "closed". You must call OpenDevice before other method calls will

work.

Except for the ReInitAll method, all methods use the ActiveTerminal property to identify the terminal to use.
