DESCRIPTION

The RP C-330 is an embedded contr oller with a built in

Basic language. Several features make it suitable as a

stand alone unit:

! Built in RPBASIC-52 programm ing language

autoruns at power up. On card flash EPROM

programmer can save 8 programs to 62K, or about

500K total.

! High speed multimode counters accept quadrature or

single inputs. Programmable for up/dow n, binary,

divide-by-N, X1, X2 or X4 quadrature counting.

Interrupt on counts.

! LCD character and gr aphic display a nd keypad p orts

for operator interface.

! Two RS-232 serial ports, one of which is

configurable for RS-422/485.

! Watchdog timer resets card if a program "crashes".

! 34 digital I/O lines, 9 of which are high current

outputs. 24 of these lines can connect to an opto

rack or other TTL devices.

! Eight channel, 12 bit resolution analog to digital

converter. Configurable operational amplifiers

allow you to signal condition inputs or measure

temperature.

! 32K, 128K, or 512K RAM battery backable to save

process variables and other data when power is off.

! 32K or 512K flash EPROM to save program s and

data.

The RPC -330 uses an 80C320 CPU operating at 22.1184

Mhz. It can operate stand alone or on a network using

the RS-485 port. Its 5.025" x 6.9" size with 4 mounting

holes makes it easy to mount in a NEMA box.

Compactness is enhanced by on-board analog and digital

terminal strips.

RPBASIC-52 programming language is standard. T his

language is a version of the original Intel BASIC-52. It

was modified for the RPC -330 for control, data

acquisition applications, and on board hardware features.

Program development takes place on your PC, using

your word processor, or on the RPC-330. Programs

from your PC can be downloaded using a serial

communication program.

MANUAL ORGANIZATION

This manual provides all the infor mation r equired to

install, configure, and operate the RPC-330. Using this

manual you will be able to:

Interface the RPC-330 to your IBM compatible PC

or terminal.

Understand the operation of the RPC-330 hardware

using RPBASIC-52 programming software.

This manual assumes you are familiar with some type of

BASIC programming software. The syntax used by

RPBASIC-52 is similar to BASIC-52. If you are not

experienced with any BASIC softwar e, y ou may w ant to

refer to books and training programs available through

your local book store. The BASIC-52 Programm ing

Manual has information and examples for the original

commands. Commands unique or modified by

RPBASIC-52 are in the Software Supplement in this

manual.

The RPC -330 uses a Dallas Semiconductor DS80C320

processor. Additional information can be obtained from

Dallas Semi (214-450-0448, FAX 214-450 0470), or

your distributor.
