General Description
These breakout boards feature two DB9 connectors (one male, one female) wired 1:1 and all pins brought out to screw terminals for easy connection. Having two connectors allows the board to be easily inserted "in-line" with an existing connection, allowing signals to pass through while being monitored, or to work with "daisy-chained" equipment. Each pin is also brought to solder pads (4 per pin) at 0.1" spacing, allowing easy addition of standard pin headers. Please note that the breakout boards are manufactured with a connection between each connector pin and the corresponding terminal block position; no soldering of any type is necessary. The solder pads simply provide an area for making optional connections to additional headers or other components.
These break out boards are perfect for experimentation and prototype work, as well as for use in the educational laboratory. They are well-suited for work with RS-232 serial ports, I/O cards, and any other device that uses a DB-9 connector. It can be helpful in making MODBUS connections. A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".
