Camera Port Termination Jumpers
JP1, JP2, JP4, and JP5 are 2-pin headers used to select 75 Ohm or high impedance
termination of the video inputs. An uncovered jumper provides a high-impedance input.
To terminate a video input port with a 75-ohm resistor, install the jumper in the position
listed in Table 14.
The 8100 ships with all four video input termination jumpers installed.
Output Power Indicator LEDs
Eight LEDs on the top edge of the 8100 show the status of the resettable fuses for the
camera ports and for each camera’s associated light module port. All eight LEDs are
normally illuminated when power is on. When an LED is off, it indicates an overcurrent
fault on the associated device port. The ports are protected by PolySwitch resettable
fuses, so removing the overcurrent condition should re-illuminate the LED.
Note
Overcurrent conditions should be corrected immediately.
