Reading Data from the Parallel
Port - The diagram below shows 5 switches connected to the
5 input lines of the parallel port. An external 5 volt power supply is used to provide high logic levels to the
input pins when the switches are open. Three 1. 5 volt batteries in series can be used to obtain 4. 5 volts which
is close enough. The 330 ohm resistors. . . . [Bill Bowden, designer]

Relay interface add-on board
for PC - . . .
Remote Relay Controller - I reprogrammed the PIC inside the LDG DTS-6R remote antenna switch to control a 8-relay PCB
I got from eBay. I built a relay driver that talks to the remote controller via two-wire rs-232 serial interface.
It has a programmable default status so the required relay states appear at power-up. . . . [Roberto Barrios

Reset Card Eases µP Troubleshooting - 10/26/95 EDN Design Idea The circuit in Fig 1a generates repetitive system resets to 68XXX
processors. These resets allow you to troubleshoot power-up problems using a scope instead of a logic analyzer or
storage scope. This reset card, which you can bu. . . [by Michael A Martone, Teleos Communications, Eatontown,

Reset ICs create sequenced or long resets - 11/20/97 EDN Design Idea Reset-generator ICs offer an inexpensive way to generate
reliable reset signals for µC and µP applications. Certain applications, such as multiple-processor systems,
require multiple resets. . . . [by Doug Anderson, Electronic Technology Corp, Ames, IA]
Resistor implements half-duplex RS-232 with echo - 11/24/99 EDN Design Idea A previous Design Idea (" SingleµC pin makes half-duplex
RS-232 , " EDN , Aug 5, 1999, pg 118) presented a way to implement half-duplex RS-232 communications without
echo. Sometimes, an echo is desirable in aµC application. You can obtain the echo by using. . . [by Matt
