Connecting your HX-20 to other devices

You can connect your HX-20 to a number of other devices-for example, to a cassette recorder, a printer, and a bar code reader, to name but a few. In this chapter you’ll learn how to connect the HX-20 to such peripherals.

Connecting your HX-20 to a cassette recorder

You can connect your HX-20 to any portable cassette recorder. However, it’s best to avoid the cheapest cassette recorders, because on these units the tape speed can fluctuate dramatically. Such fluctuations in tape speed can make it impossible for you to recover programs and data you have stored on your cassettes. To ensure a consistent tape speed, you should use fresh batteries if your cassette recorder is powered only by batteries, as the tape speed on these units will change as the batteries drain down. Even better, use an AC-powered cassette recorder, or get an AC adapter for your battery -powered unit.

One very desirable feature is a digital tape counter, which makes it easy to advance or rewind a cassette to the exact location of any previously-saved program or data file. Without a digital tape counter, you may only be able to save one program or data file on a cassette.

Tone and volume controls are also useful. A REM jack is essential for all but the simplest applications. A good quality micro- cassette recorder will serve as well as a unit that uses full-size cassettes.

Once you have a cassette recorder, you will need a cable to connect it to the HX-20. This cable, available from your Epson dealer as part #702, looks like this:
