1. From the Windows START button select

PROGRAMS, then ACCESSORIES, then

HYPERTERMINAL. A window called HyperTerminal

will open up. Look for the ICON with Hypertrm.exe

beneath. Double click on it to start HyperTerminal.

2. HyperTerminal will first open up a window called

Connection Description (see Figure 7). HyperTerminal

is a full featured terminal emulation program that can

work with dial up connections and modems, and is

designed to store all this connection-specific data. We

don’t need a lot of these features, for what we want to

do which is to create a dumb terminal connecting

directly to one of the COM ports, but we have to go

along with HyperTerminal’s requirements to get there.

In the Connection Description window, enter a name

that you like for the configuration that you are about to

set up e.g. “9600 Dumb” and also choose an icon that

you like the look of. Click the O.K. tab.

If you are using a RS232-485 converter on one of the

computer internal COM ports then enter the

appropriate COM port. Most desktop computers

provide 2 internal COM ports, COM1 & COM2

(laptops may have only one) that are brought out on

the rear as 25 or 9-pin connectors . If you are using a

plug-in RS-485 card or an RS-232 serial port

expansion card, these ports will probably end up

being set to COM3 and/or COM4, whatever Window’s

device manager has permitted as satisfactory for

installation without resource conflict. Enter the

appropriate COM port and click the O.K. tab.

4. The next window that opens up is titled Comx

Properties. The first box is Bits per Second. Select

the speed (9600, 2400, 1200 or 300) to correspond

with the speed selected on the 2 position baud rate

dipswitch on the DTL-IFB-485 (usually 9600 is the

best choice). Set Data Bits to 8, Parity to None, Stop

Bits to 1 and Flow Control to None.

3. A window titled Phone Number will now open up.

Well, we don’t have a phone number for a dumb

terminal, so go down to the Connect Using: box and

select Direct to ComX where X can be 1,2,3 or 4 (see

Figure 6).

Figure 6. Direct to Com Port Screen

The Advanced button controls FIFO buffer settings for

the COM port UART, the speeds that we are using are

so slow that these settings are fairly irrelevant, choosing

default will work fine.

After selecting O.K. you will finally reach the terminal

window (see Figure 8), but there are still more

configuration details to set.
