Boot sequence
A PC Microcontroller can be configured to boot from the on-card solid-
state disk, an external floppy disk, or hard disk.
Serial ports protected against ESD
The COM1 and COM2 serial ports are 16C550 compatible. The 16 byte
FIFO buffers minimize processor overhead in high speed serial commu-
nications. Baud rates are programmable from 150 to 115 KB baud.
Both ports have an RS-232 interface with the RS-232 voltages gener-
ated on-card. The serial ports meet the new IEC1000, level 3, ESD
protection specification with ±8 KV of ESD protection. Backdrive pro-
tection is also included.
CAMBASIC supports the serial ports with interrupt driven, 2 KB input
and output buffers which operate in the background. This ensures that
data is not lost while critical control loops are being executed.
Note The network interface module is not compatible with the 6010 model.
Convenient I/O termination with the breakout board (BOB)
Except for the serial and industrial I/O lines, all other I/O is terminated
with a 34-pin IDC connector, also called the AUX I/O. The AUX I/O
port eliminates cable clutter and the possibility of cables being plugged
into the wrong sockets during maintenance. The breakout board termi-
nates each function at the appropriate connector. These functions
include the keyboard, speaker, printer, floppy drive, battery, and opto-
isolated interrupts.
Speaker and keyboard
The PC Microcontroller accepts a PS-2 style AT keyboard and provides
speaker output through the breakout board (BOB).
Parallel port is multifunctional
The multifunctional parallel port can be used as a printer port or gen-
eral purpose I/O. The parallel port can also interface with a floppy disk
drive, drive alphanumeric displays and matrix keypads, or drive high
current AC and DC loads using an opto rack and opto modules.
The multifunctional parallel port applications include:
n
LPT1 for PC compatible printers
n
17 general purpose digital I/O lines
n
4 x 4 matrix keypad
n
4 line alphanumeric display
