Tiny Server - The device that converts RS485 and RS232 to the ethernet LAN has been developed. The device
was built with the Lantronix XPort embedded ethernet server and the industrial standard differential RS485
transceiver, 75176 and the single-end RS232 driver, MAX232. The XPort module provides 10/100 ethernet port
and the +3V logic UART. The 75176 and MAX232 are +5V TTL logic. . . [Wichit Sirichote, designer]
Trace voltage-current curves on your PC - 11-Oct-01 EDN Design Idea Some years ago, one of the fundamental electronic instruments
was the laboratory curve tracer. A CRT display would sweep out terminal behavior (current versus voltage]
from which you could derive mathematical models. Classic present. . . [by Clayton Grantham, National

Track multisite temperatures on your PC - 04/18/02 EDN Design Idea The low-cost circuit in Figure 1 allows you to track four
remote temperatures with thermistor sensors through the parallel port on your PC. This four-zone thermometer
instrument has a temperature range of –40 to +90°C and a resolution of better than ±1°C. You can calibrate
its accuracy to within 1°C over a 0 to 50°C span and within 3°C over a –40 to +90°C span. Thermistors are
low-cost , passive, rugged components, making them a good choice for temperature sensing. The
signal-conditioning hardware in Figure 1 performs a simple voltage division to partially linearize the
thermistors. . . . [by Clayton Grantham]

Transfer data frames over asynchronous RS-232C lines - 01/15/98 EDN Design Idea The asynchronous RS-232C interface is a simple, low-cost option
for interconnecting processor-based systems. In many applications, you need to transfer variable-size
messages. However, the character-oriented RS-232C protocolThis F. . . [by SK Shenoy, Naval Physical and

TSR Logs Assembler & Compiler Errors in File - 04/27/95 EDN Design Idea If you use a PC to develop software for embedded systems, you
probably still use good, old MS-DOs for mOst of your processing, because mOst compilers, assemblers, and
linkers don't run under MS Windows. If you're developing a sizable program, you probably use automated
procedures such as batch files or "make" files to build and rebuild your target program. When you use batch
files or make files, capturing the PC's screen output in a disk file is more convenient than sitting around,
watching everything endlessly scroll by on the screen. . . . [by John S Santic, Computer Consultant,
