Serial and Parallel Loopback Plugs
High Quality, Fully-Molded Serial and Parallel Loopback Plugs
Loopback plugs are the quickest, most effective way to test that a PC's serial (RS232) and parallel ports are working correctly. These adapters plug into the serial and parallel ports of a computer, allowing the looping of the data and signal path by joining the transmit and receive pins together. These loopback plugs are designed to work in conjunction with BurnInTest Professional allowing the quick diagnostic and troubleshooting of problems affecting serial and parallel ports.
The Serial Loopback Plug is a 9 pin female plug (DE-9) and the Parallel Loopback Plug is a 25 pin male plug (DB-25).
In addition to testing the receive and transmit functions, the following RS232 signal pins are also tested by the Serial Loopback plug: Clear To Send (CTS); Request To Send (RTS); Data Set Ready (DSR); and Data Terminal Ready (DTR).
