# Test Preferences – Parallel ports

(Applicable to BurnInTest Pro version only)

Parallel port

The communications port that will be used by the parallel port test, e.g. LPT1, LPT2 or LPT3 (only ports currently installed will be displayed). See the parallel port test for more details.

Only a single parallel port may be tested at one time.

Test type

It is possible t select either a “Detect and loopback test” or a “Detect only” test. The, detect and loopback test, requires the use of parallel port loop back plug. The, detect only, test does not require a loopback plug. When possible use the loopback test as it is a more though test.
