A.2.7 Write Protection (J14)
The VTM28 provides a Write Protection Jumper. If the jumper is off J14, all
programmable devices of the XVR16 are hardwired write protected. If the jumper
is on J14, all programmable devices of the XVR16 are NOT hardwired write
protected. See the note at the end of
section E.2 Non-Volatile Memory,
150 for additional information.
