ESL Breakout Boxes / Interface Analyzers are Made in the USA.

The Model 900 EIA/TIA RS-530 Interface Analyzer is a diagnostic tool designed for use at the standard EIA/TIA RS-530 data 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.

The Model 900 is of optimum design. It utilizes red and green light emitting diodes to clearly display polarity, activity, and validity of all interface signals. Miniature slide switches allow the user to program a 'make' or 'break' for each signal at the DCE/DTE interface. Mini-patchcords are provided for cross-patching or loopback patching of signals at the front panel test point array.

A complete table of EIA/TIA RS-530/530-A standard interface signal descriptions is provided inside the unit for ready reference during testing. A covered compartment provides secure storage for mini-patchcords and an EIA/TIA ribbon cable. The Model 900 is battery powered for complete portability, pocket sized for convenience, and packaged in a sturdy aluminum case with metal hinge for durability in field use.
