DTL-IFB-485

Interface Board for Serial-Input Electronic Loads

Utilizing Windows™ “HyperTerminal”

to Control the DTL-IFB-485 (RS-485

Interface Board for 100 Watt Serial Input Loads)

Many users will take the WinBurn-485X, Active X software

component, and design their own installable software

program to use in controlling the DTL-IFB-485 and

DTLXA Series of Electronic Loads. An alternative

approach outlined herein, is to use a "dumb terminal" or

a "terminal emulation program" to send and receive

commands to and from the DTL-IFB-485.

If you don’t have a dumb RS232 terminal handy (who

does these days) a terminal emulation program running

on a PC, will do the same job just as well. Windows 95/

98 provide a standard terminal emulation program called

HyperTerminal (see Figure 3), which is usually located

in the Accessories folder after Windows installation.

This technical description explains how to configure

HyperTerminal to operate with the DTL-IFB-485. An

RS232 to 485 adapter (See Figure 4, DTL-RS232-485

product, or Figure 6, for schematic) can make it easy to

connect to an RS-232-standard serial communication

port (see Figure 5) of a personal computer (PC).

In the days of DOS, there were many terminal emulation

programs available (example: Bitcom). If you want to

operate under DOS, these will work just fine.
