• If the interface cable is unplugged, or you loose power on the
computer and/or the PI54 cabinet during the upload process,
you can simply abort the upload and restart it. Error
messages will provide guidance.
• When the PI54 cabinet detects that software is uploaded, it
will automatically present a relevant information page, and
the keypad will be locked. It is not possible to switch off the
PI54 cabinet during the software upload, except by
disconnecting power.
Critical process
Once all the software data have been uploaded correctly to the
scratch pad, it will automatically be transferred to the
microprocess or (Flash PROM). This is a critical process.
When the message Start erasing boot area in Flash PROM
appears the internal transfer process has started. This process
will only last a few seconds. The end of the criticial process is
identified with the message Switch power off and on again to
start the new program.
If you loose power on the PI54 cabinet during this critical
internal transfer process, you can not restart the upload. You
must then contact your Simrad dealer to have the PI54 cabinet
shipped for reprogramming.
