ELECTRICAL

CPU

64180, 9.216 Mhz clock

Memory

CAMBASIC II, 32K ROM

Program ming and data is 128K RAM standard, 512K

Optional.

Program is 32K EPROM (U3)

Memory speeds are 80 ns or faster

Digital I/O

The SBS-2300 has 48 digital I/O lines. 24 are from J2,

which is a general purpose port. The other 24 are from

J3. J3 has 8 high current outputs, which may be

jumpered for inputs. The keypad port, J5, uses 8 of the

24 lines. All ports use an 82C55 for interfacing.

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

the eight high current lines at J3.

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 J3

8 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

10 lines accept a 16 position matrix keypad. Scanning

and debounce performed in CAMBASIC II.

Serial ports

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

CTS lines. COM 1 has only these lines. COM2 also has

an RTS line. Baud rates fr om 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:120ns or faster.

Watchdog timer, reset
