RS-232 BreakOut Box with "RS-232 Made Easy" Book

This portable, pocket-size BreakOut Box provides access to all 25 conductors of the RS-232/V.24 interface between the DTE and DCE equipment. LEDs monitor the status of ten primary signals: TD(2), RD(3), RTS(4), CTS(5), DSR(6), CD(8), TC(15), RC(17), DTR(20), ETC(24), and two additional LEDs for spares.

Twenty-four miniature switches allow all interface conductors (except frame ground on pin 1) to be individually interrupted for isolated testing and observation of terminal and modem signals. Small jumper cables are provided to allow cross connection of signal lines.

The 232BOB1 comes with a 28-page instruction manual which helps you understand RS-232. The manual explains serial data and helps you interconnect two serial devices. This model also includes a copy of the book "RS-232 Made Easy" which goes into greater detail.
