Test all 9 IO on standard RS232 port with LED indication and loopback test. The RS232 Interface tester can be connected across any serial port (at a SUB-D9 interface) to visually monitor the outputs on LED and set any input signals through switches. The interface tester is installed at an existing serial connection and offers easy testing as well as a loop-back connection test. It has a header for RS232 interface, providing easy access to all interface pins, allowing you to perform tests (e.g. with a multimeter test set, oscilloscope, etc.) during runtime.
