70. To use the I/O ports of the MegaDome
®
,
locate the “J7” connector.
NOTE: There are
two connectors that look identical, be sure to
use the one adjacent to the capacitor labeled
“1000 jFK.8L9” shown in
Image 33.1
and
NOT the one adjacent to the hole in the back
of the camera as shown in
Image 33.2
.
71. Run the I/O cable through the hole in the
bottom of the camera and plug it into the “J7”
connector as shown in
image 33
.
NOTE: The
connection is a little stiff so be sure to apply
enough pressure to connect it; using a flat
head screw driver to push it in is
recommended.

NOTE: Both the input and the output are electrically
isolated from the rest of the camera’s
electrical circuitry via general-purpose photo
couplers. The input is additionally protected
with a serial 250 Ohm resistor, and a
debouncing circuit. Duration of any input
signal should be at least 5 ms to comply with
the requirements of the debouncing circuit.
