Overview
Watchdog timer added for safety
The watchdog timer resets the system if the program stops unexpect-
edly. The watchdog is enabled, disabled and strobed under software
control. The time-out is 1.6 seconds (typical).
Real time calendar/clock with battery-backup
The real time clock is fully AT compatible and uses the standard DOS
calls. An optional off-card battery powers the real time clock when the
5 volt supply is removed. A connector is provided for the external bat-
tery. The real time clock also provides the user with 128 bytes of user-
defined CMOS-RAM.
I/O connectors
With the exception of the mouse, keyboard, and IDE, all I/O connectors
can be latched to prevent connector movement during shock or high
vibration.
Keypad and LCD display support for low-cost operator
interface
For embedded applications, the parallel printer port or the EZ I/O port
can interface with a 16-key matrix keypad and a 2- or 4-line LCD dis-
play. The PC-510 is supplied with software that provides keypad scan-
ning and display operation. Supplied display and keypad drivers in C
support these devices.
Hardware reset
A hardware reset can be done by any of the following methods:
n
Issuing the RESET software command (using the watchdog
function)
n
Depressing the reset switch
n
Cycling power
n
Configuring the opto channel for RESET.
A hardware reset ensures complete reset of the system and all attached
peripherals. An expired watchdog timer cycle also causes a hardware
reset to occur.
5 Volt operation lowers system cost
The PC-510 operates from a single 5V ±5% supply. Located across the
power supply, the 6.2V, 5W zener diode protects against reverse voltage
and limits over voltage. The power supply generates the RS-232 volt-
ages on-board the PC-510. The locking power connector is a standard
PC power header connector.
