Model 700 EIA-RS232 Breakout Box Now Includes Set of Two Voltage Test Points

December 1, 2011

For Immediate Release


Electro Standards Laboratories, Cranston, RI, announces the newly re-designed Model 700 Breakout Box and Interface Analyzer. TheModel 700 is a diagnostic tool for use at the standard EIA RS-232 or CCITT V.24data interface of modems, multiplexers, terminals, and computers. It is simply inserted in series between the DTE (Data Terminal Equipment) and the DCE (Data Communications Equipment) to provide access to and monitoring of all data,timing and control signals.


This product now features a set of two voltage test points,one plus ( ) and one minus (-). This added feature enables the user tosynthesize missing control signals. This new feature combined with thetri-state (3 colors) LED's that display polarity, activity and validity of all interface signals make this product an invaluable tool for field servicetechnicians. Tri-state indicators allow for efficient monitoring of bipolar interface signals and present the user with a maximum of signal status information.


Miniature rocker switches allow the user to program a ‘make’or ‘break’ for each signal at the DCE/DTE interface. Mini-patchcords areprovided for cross-patching or loopback patching of signals at the front panel test point array.


A complete table of EIA/CCITT standard interface signal descriptions is provided inside the unit for ready reference during testing. Acovered compartment provides secure storage for mini-patchcords and an EIA ribbon cable. The Model 700 is battery-powered for complete portability, pocket-sized for convenience, and packaged in a sturdy aluminum case with metalhinge for durability in field use.
