INTRODUCTION

SETUP AND OPERATION SECTION 2

The RPC-220 is ready as soon as you connect it to a PC

and apply power. This section describes what is needed

to get a sign on m essage. A demonstration program will

also be downloaded.

"Development System Setup" describes hooking up using

components from our development system.

OPERATING PRECAUTIONS

The RPC-220 is designed to handle a wide temperature

ranges at low power. These characteristics require using

CM OS com ponents. CM OS is static sensitive. T o avoid

damaging these components, observe the following

precautions:

1. Ground yourself before handling the RPC -220 or

plugging in cables. Static electricity can easily arc

through cables and to the card. Simply touching

your PC befor e you touch the card can greatly

reduce the amount of static.

2. Do not insert or remove cables or components when

power is applied.

EQUIPMENT

You will need the following equipment to begin using the

RPC-220. If you ordered the development system, the

' !' items are supplied.

!RPC-220 embedded controller

!VTC -9F ser ial cable

!Power supply, 6 to 15 VDC @ 300 m a or

+ 5, 300 ma

PC with a serial port and communications program

(such as Microsoft Windows Terminal or Procomm)

Refer to SECT ION 4, "SERIA L PORT PIN O UT" , for

wiring information to make your own serial cable.

The application disk is necessary to run the

demonstration program. This disk is included in the

development system.

DEVELOPMENT SYSTEM SETUP

A development system has most of the software and

hardware needed to get your card operating. All you

really need is a PC with a serial port and a serial

communications program. A development system

includes terminal boar ds with cables to easily access

analog and digital I/O.

You can install the C compiler at any time.

You may want to put in the stand-offs to the board. This

keeps the board from touching metal or other surfaces

where the battery could discharge.

Refer to Figure 2-1 on the next page. Connect the

power cable assembly (P/ N 1725) to "Pow er In" on the

board. The RED wire goes to P1 terminal marked "V".

Black goes to P1 terminal marked "G".

You may plug the pow er supply into a 120 VA C wall

outlet or power strip. Power may be applied or removed

from the RPC-220 board by plugging the 3.5mm

connector from the power supply to the pow er cable

assembly.

Continue with "First Time Operation" below. Since the

power supply is set up, skip step 1.

Application Programs

To use the application and demonstration programs, you

must put them to your hard drive first. They can be any

place you want. Make up a subdirectory and run 'RPC-

200.BAT' to extract the files. This program expands

files in the current DOS directory and creates additional

subdirectories.

DEVELOPING UNDER WINDOWS

You can write, compile, and debug under Microsoft

Windows 95 or NT. An easy way is to create a folder

and put your editor (Word, Wordpad, Note pad, or

other), terminal program, and MS-DOS icon in it. Open

the editor and terminal progr ams and use the task bar to

switch between the two.

The Windows ' Terminal' program configuration file,

mon220.trm, is supplied on the applications disk. You

may need to change the COM port.

MS-DOS properties are changed to invoke the compiler.

(Properties are selected by first right clicking on the MS-

DOS icon). ' Cmd l

ine:' box is changed to:

C:\mc\CC51 \rpc220\subdir\fname.c -p -i

' subdir' is the directory you are writing your program

in. ' fname.c' is the file you are compiling. Additional

command line options, such as ' -p -i', are at the end.

The ' W

orking:' directory is nearly the same:

c:\rpc220\subdir
