SETUP AND OPERATION

INTRODUCTION

The RPC -320 is ready to program as soon as you connect it to a ter minal or PC a nd apply pow er. This chapter describes what is needed to get a sign- on message and begin program ming.

Requirements for uploading and downloading programs are discu ssed. A "W here to go from here" section tells you what chapters to refer to in order to use the various capabilities of the RPC-320. Finally, a troubleshooting section helps out on the most com mon pro blems.

OPERATING PRECAUTIONS

The RPC -320 is designed to handle a wide variety of temperature ranges at low power. These characteristics requir e using CM OS com ponents. CM OS is static sensitive. T o avoid damaging these c omponents, observe the following precautions before handling the RPC-320.

1.Ground yourself before handling the RPC -320 or plugging in cables. Static electricity

can easily arc through cables and to the card. Simply touching your PC before you touch the card can greatly reduce the amount of static.

2.Do not insert or remove components when power is applied. While the ca rd is a + 5 volt only system, other voltages generated on the card which affect other com ponents.

EQUIPMENT

You will need the following equipment to begin using the RPC-320:
