Electrical Specifications
This section describes the electrical specifications of the MVS-8100D including power
requirements and signal descriptions. Refer to Figure 10 on page 26 for the location of
the ports and LEDs described in this section.
Power Requirements
Power to the board is provided through the PCI bus for +5 VDC.
Table 13 shows the +5 VDC draw from the MVS-8100D and from each attached CDC
series cameras. The voltage requirements in this table have a tolerance of ±5%.
Fuses
There are no user-replaceable fuses on the MVS-8100D.
Each camera input channel is protected by a PolySwitch resettable fuse at 750 mA per
channel. Each parallel I/O line is individually protected by a PolySwitch fuse at 200 mA
per line.
If an over voltage or over current condition occurs on a camera input channel or on any
parallel I/O line, the PolySwitch fuse trips, opening the circuit. You need only remove the
device, correct the overcurrent condition, wait a few minutes for the PolySwitch circuitry
to cool down, then plug your device back in. The fuse resets itself.
Standards Compliance
The MVS-8100D meets the following worldwide standards for safety, electromagnetic
compatibility, and electrostatic sensitivity.
