TECHNICAL INFORMATION

Page 22 RPC-150

ELECTRICAL

CPU

64180, 9.216 Mhz clock

Memory

CAMBASIC, 32K ROM

Programming and data is 32K RAM

Program is 32K EPROM (U3)

Memory speeds are 80 ns or faster

Digital I/O

The RPC -150 has 47 digital I/O lines. 23 are from J2.

The other 24 are from J3. J2 has 7 high current outputs,

which may be jumpered fo r inputs. The keyp ad port,

J5, uses 8 of the 23 lines on J2. All ports use an 82C55

for interfacing.

The specifications below are for all digital I/O except for

the eight high current lines at J2.

Drive current 2.5 ma maximum per line,

sink or source. TTL

compatible.

Output low voltage 0.45V max at 2.5 mA, 1V

max at 15 mA for opto rack.

Output high volts 2.4V minimum, sink or source

at rated current.

All digital input lines are TTL compatible.

High cu rrent ou tput at J2

7 of the 24 lines can drive up to 500 ma at 50V. Refer

to CHAPTER 6, D IGITAL AND OPTO PORTS for

limitations.

Keypad input

8 lines accept a 16 position matrix keypad. Scanning

and debounce performed in CAMBASIC.

Serial ports

Two RS-232D serial ports. All have RxD and TxD

lines. COM1 has only these lines. COM2 also has CTS

and RTS line. Baud rates from 600 to 38. 4K, 7 or 8 data

bits, parity even, odd, or none, 1 or 2 stop bits.

EPROM and programmer

Accepts 29C256 or equivalent EPROM.

Size:32K

Speed:200ns or faster.

Power requireme nts

+ 5VDC ±5% at 100 ma.

RS-232 voltages generated on card.

Current consumption does not include any opto-modules

or other accessories.
