ELECTRICAL INPUTS
Ed can be powered from:
1.PCI or PCI-e bus (12VDC)
and / or
2.Battery Input ( 12VDC ) using supplied cable
Ed Powered from the POWER SUPPLY INPUT
Ed can be powered from both PCI/PCI-e and/or external input.
By selecting the correct PCI adaptor, Ed can be powered using 12VDC supplied by a computer. This source is sufficient for
opereation of Ed.
As an alternated source or for redundancy, Ed has an external power connector equipped with a Molex minifit jr female
connector. MCDI supplies a male connector without lock at one end and lead at the other. The lead end should be connected to
a 12VDC power source such as battery or power supply. Both inputs can be connected at same time as Ed will supervise both
and switch automatically from one to the other upon need.
External input is made for well regulated, low transient and ripple 9-12VDC current only. Supply should be 9VDC 300 Ma
minimum for regular operation. Severe damages to the unit may occur if power supply delivers more than 14VDC. As a general
rule, higher tension will create more heat inside computer and may diminish life expectancy of Ed.
Power led in located on major component surface of Ed.
Alternatively, Ed could be made to work outside PC or in a adequate box using the external power source. MCDI assumes no
reponsability for operation out of a MCDI designed box.
WARNINGS
-Removal of the power source during reception of an alarm signal may result in losing said signal.
-Removal of one power source may result in shutdown and loss of signal if second power source is not available within 5ms
and/or if tension is inferior to 8V DC.
-If 9-12VDC input is used as Ed
sole source of power, events in receiver buffer will be not be lost when power is removed and
will be transmitted to PC when power is restored.
-Ed is not equipped with a battery charger. Indication of remaining battery life are approximate and based solely on measure of
tension between positive and negative poles.
Ed can power from a 12VDC battery as the only current source. Preferably use MCDI supplied cable (Molex minifit jr to leads,
red and black wire). DO NOT INVERT POLARITY. Severe damages to the unit may occur if the battery delivers more than 14V
DC.
Indicator in Configurator will indicate which electrical input is used and approximate battery level if connected. Battery level is
based on voltage thresholds: 100% >9.5, 75% <8.5V, 50% <7.5V, 25% <6.5V, 0 <6VDC
Status may take up to 5s to display correctly.
