Software Tools

Program

Description

The Site Master Software Tools program provides the means for transferring the measured trace, along with any applied markers and/or a limit, to the screen of an MS-DOS based personal computer (PC) running Windows 95/98/NT.

Requirements

The Site Master Software Tools program is a standard Windows program and will run on any computer that will run Windows 95/98/NT. Typically, this means having a PC with the following characteristics:

￿ Pentium microprocessor (100 MHz or better, recommended) ￿ Microsoft Windows 95/98/NT

￿ 32 MBytes of memory, minimum

￿ Approximately 15 MBytes of available hard drive space

Communication Port Setting

The Site Master Software Tools communicates with the Site Master through a standard

 

COM port on the PC. It is important that your Windows COM port settings conform to the

 

actual hardware settings. Since various add-in devices such as sound cards, modems, and

 

network cards use IRQ (Interrupts), it is possible that your computer has non-standard

 

COM port settings. Please consult your computer vendor for COM port address and IRQ in-

formation.

Changing COM Port Settings–Windows 95/98/NT

 

Step 1. Open the Windows Control Panel.

 

Step 2.

Double click on the SYSTEM icon. The System Properties window appears.

 

Step 3.

Select Device Manager. The Device List appears.

 

Step 4.

Double click on the item Ports (COM & LPT) in the device list.

 

Step 5.

Double click on the communications port you want to set. The Communications

 

 

Port Properties window appears.

 

NOTE:

If Windows doesn't show any available COM Ports, consult your computer manufacturer.
