RS-232 terminal/monitor. Build this powerful serial-bus analyzer (SBA) which works like an expensive unit, but costs little more than a quality break-out box. Can also double as a portable, battery-operated keyboard/terminal. Est. cost: $75 (kit).

Universal RS-232 connector is essentially a dedicated break-out board that makes the signals easily accessible and reconfigureable.

Cable tester. Build a low-cost multipath continuity tester that uses electronic switches to move the "probe" from wire-to-wire. Est. cost: $40 (kit).
ELECTRONICS NOW Jul 1995 (v.66#7) pg. 69

Serial cable tester uses eight LED pairs (and switches) to test the continuity of the eight most important lines of an RS-232 cable.

POPULAR ELECTRONICS [2] Mar 1994 (v.11#3) pg. 28

Cable-tester and wire-tracing system. A transmitter circuit generates four distinct audio tones that are received at the output using a receiver circuit. Used to trace and correctly connect multi-wire cables.
POPULAR ELECTRONICS [2] Apr 1996 (v.13#4) pg. 65

RS-232 probe circuits use a 3-volt window comparator to test the active input and output lines.
POPULAR ELECTRONICS [2] Feb 1997 (v.14#2) pg. 76

DTMF wire tracer. A tone generator placed at one end of a wire bundle, and a tone decoder at the other end, allows up to 16 conductors to be easily identified in only a matter of seconds.
