Features
– Tiny size and low price make these units a good resource to keep in your tool kit.

– Large, colorful LEDs are easy to see.
– Standard RS-232 DB9 interface means you don’t need any jumpers, switches, or special cables.

It’s easy to test RS-232 signals on DB9 ports, such as those on printers, PCs, or notebook computers.
Just attach PockeTester to any RS-232 DB9 interface. A quick look at the LEDs tells you the status of each line: mark, space, or no signal.
PockeTester monitors the seven most important async data and control lines: TD, RD, DTR, DSR, RTS, CTS, DCD. All nine pins are wired straight through for accurate testing.
Check system status instantly from anywhere in the room. The large red and green LEDs have a high color intensity and a wide viewing angle, making them easy to read. The Black background of the molded case provides a good contrast to the LEDs for even better visibility. In fact, you can even infer data bias from the intensity of the color.
