6416m Rear Panel Features
All 6416m rear‑panel features and functions are described in this section.
AC Power
Pro64 modules use switching power supplies that can operate at 100‑240V
and from 50‑60Hz, meaning that they can be used with most of the world’s
AC power systems by simply changing the line cord. The 6416m is equipped
with a standard grounded IEC power inlet (with fuse), which can accept the
interchangeable IEC power cord.
Fuse
The fuse holder is spring‑loaded and has space for two fuses, one main and
one spare (optional). Press the fuse holder cover to access the fuse. When
checking or replacing a fuse, always power off the Pro64 unit and remove the
line cord from the AC power source.
Always replace the fuse with one with the same rating as that being
changed.
Backup DC Power
For applications where a backup power source is required, the 6416m is
equipped with a DC power inlet using a locking 4‑pin XLR jack. A DC power
supply capable of outputting 24VDC ±5% at 1.75 amps is required. In the
locking XLR plug, connect pin 1 to ground and pin 4 to the 24VDC source.
Nothing should be connected to pins 2 and 3.
