an ASCII printer. However, because the data is transmitted through a serial port, a device

known as a Serial to Parallel converter is necessary in order to make a direct connection

between the printer and the T35-GFX.

Alternately, the ASCII graph may be captured using a PC, and then sent to the PC printer

like any other document. These features are discussed in more detail later in this manual.

COMP MAN and COMP AUTO

COMP MAN and COMP AUTO are intended for PC interface for TurboLabel use. We’ll

talk about TurboLabel a bit more in due time.

REAL TIME

REAL TIME stands for real time data output.

Real time data output will give more data with a higher resolution (smaller measurement

time interval) than the stored data feature mentioned above; it is measured and output

once per second, as opposed to stored data that is collected once every 5 seconds. For

another thing, real time data is output as it occurs, and so there is no storage size

limitation on real time data. The T35-GFX data output will continue for as long as the

charge or discharge lasts.

How you use this data is up to you; you could import it into a Microsoft™ Excel™

spreadsheet and do fancy analysis on it; you might also print a very nice color graph. You

might even write a program to use this data, and a number of our customers have done

exactly this.

The Serial Port

The comm link to the outside world is a

standard RS-232 format (also known as

EIA232) using a DB-9 connector with

female pins.

Hardware Configuration Details

The connector is intended for interface to an IBM-compatible PC serial port and is wired

for use with a standard PC serial cable; if you are in the US, you can get this cable at any

Radio Shack® as of the time of this writing. As USB is becoming more and more popular
