Figure￿2-12￿IEEE￿1394￿troubleshooting￿process￿￿

To￿determine￿if￿the￿computer’s￿IEEE￿1394￿system￿is￿functioning￿properly,￿perform￿the￿

following￿procedures.￿Figure￿2-14￿outlines￿the￿process.￿Start￿with￿Procedure￿1￿and￿continue￿

with￿the￿other￿procedures￿as￿instructed.￿

Procedure￿1:￿ IEEE￿1394￿device￿check￿

Procedure￿2:￿ Diagnostic￿check￿

Procedure￿3:￿ Connection￿and￿replacement￿check￿

Procedure￿1￿ IEEE￿1394￿device￿check￿

Connect￿an￿IEEE￿1394￿device￿to￿the￿computer’s￿IEEE￿1394￿port,￿then￿boot￿the￿computer￿for￿ Windows￿Vista.￿The￿computer￿should￿automatically￿detect￿the￿1394￿device.￿Check￿whether￿ the￿device￿can￿transmit￿data￿to￿the￿computer.￿

If￿the￿device￿is￿able￿to￿communicate￿with￿the￿computer,￿the￿problem￿may￿be￿intermittent￿or￿ connections￿may￿be￿faulty.￿Go￿to￿Procedure￿2.￿￿

If￿communication￿is￿impaired,￿there￿may￿be￿a￿faulty￿connection.￿Go￿to￿Procedure￿3.￿

Procedure￿2￿ Diagnostic￿check￿

Run￿the￿Diagnostic￿Program,￿which￿will￿automatically￿execute￿the￿IEEE￿1394￿Device￿check.￿￿ Refer￿to￿Chapter￿3.￿Tests￿and￿Diagnostics￿for￿more￿information￿PLS￿use￿windows￿ application.￿

If￿an￿error￿is￿located,￿go￿to￿Procedure￿3.￿￿If￿an￿error￿does￿not￿occur,￿the￿1394￿port￿is￿ functioning￿properly.￿

Procedure￿3￿ Connection￿and￿replacement￿check￿

The￿transmission￿cable￿may￿be￿damaged￿or￿the￿connections￿may￿be￿loose.￿Perform￿Check￿1:￿

Check￿1￿ Make￿sure￿the￿transmission￿cable￿is￿firmly￿plugged￿into￿both￿the￿IEEE￿1394- compatible￿device￿and￿the￿IEEE￿1394￿port￿of￿the￿computer.￿If￿the￿cable￿is￿ connected￿correctly,￿go￿to￿Check￿2.￿

Check￿2￿ Make￿sure￿the￿IEEE￿1394￿port￿is￿firmly￿secured￿to￿the￿system￿board￿of￿the￿ computer.￿If￿the￿malfunction￿persists,￿go￿to￿Check￿3.￿

Check￿3￿ The￿transmission￿cable￿may￿be￿damaged.￿Replace￿with￿a￿good￿cable.￿If￿the￿ malfunction￿persists,￿go￿to￿Check￿4￿
