A.1.11 Write Protection (J2000)
The VTM26 provides a Write Protection Jumper. If the jumper is off J2000, all
programmable devices of the XVR16 are hardwired write protected. If the jumper
is on J2000, 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.
A.1.12 LED
The rear status LED signals provide the board status at the VTM26. The signal
already implemented the serial resistors on the XVR16.
A.2 VTM28 Transition Module
This section describes the VTM28 Transition Module. This transition module
would be used with the XVR16 in the special case that the XVR16 ordering
configuration has H = 0 and G = 1 or 4, in order to provide support for PMC I/O
through two MEZZIO connectors for all of the XVR16 PMC I/O sites. If other
signals are needed rather than PMC I/O, then it is recommended to purchase a
VTM26 transition module or contact Sales for custom ordering options. Please
refer to
for the location of available interfaces.
