DESCRIPTION

The RP C-330 is a n embed ded contr oller with a built in
Basic language. Several featur es make it suitable as a
stand alone un it:

Built in RPBASIC-52 programm ing language
autoruns at power up. On card flash EPROM
program mer can save 8 progr ams to 62K, or about
500K total.

High speed multimode counters accept quadrature or
single inputs. Program mable for up/dow n, binary,
divide-by-N, X1, X2 or X4 quadr ature counting.
Interrupt on cou nts.

LCD charac ter and gr aphic display a nd keypad p orts
for operator interface.

Two R S-232 ser ial ports, one of whic h is
configurable for RS-422/485.

W a tc h do g ti m er r e se ts ca r d i f a p ro g ra m " cr a sh e s" .

34 digital I/O lines, 9 of which are high curre nt
outputs. 24 of these lines c an connec t to an opto
rack or o ther TT L 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 EPRO M 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.

RPBA SIC-52 p rogr amm ing language is standard . T his
language is a version of the original Intel BASIC-52. It
was m odified for the RPC -330 for c ontrol, data
acquisition applications, and on board har dware fea tures.

Program development takes place on your PC, using
y o ur w o r d p r o ce s so r , o r on th e RP C - 3 30 . P r o gr a m s

from your PC can be downloaded using a serial

MANUAL ORGANIZATION

This m anual pro vides all the infor mation r equired to
install, c onfigure , an d opera te the RP C-330. Using this
manual you will be able to:

Interface the RPC-330 to your IBM compatible PC
or ter minal.

Understand the operation of the RPC-330 hardware
using RPBASIC-52 programming software.

This manual assumes you are fam iliar with some type of
BASIC progr amming software. The syntax used by
RPBASIC-52 is similar to BASIC-52. If you are not
experie nced with a ny BASIC softwar e, y ou may w ant to
refer to books and training program s available through
your local book store. The BASIC-52 Programm ing
Manual has information and examples for the original
commands. Comm ands unique or modified by
RPBA SIC-52 a re in the Sof tware Supplem ent in this
manua l.

The RPC -330 uses a Dallas Semiconductor DS80C320
processor. Additional information can be obtained from
Dallas Semi (214-450-0448, F AX 214-450 0470), or
your distributor.
