LED Color Description
Network Green Steady for connection to 100 Mbit/s network. Flashes for network activity.
Amber Steady for connection to 10 Mbit/s network. Flashes for network activity.
Unlit No connection.
Status Green Shows steady green for normal operation. Note: The Status LED can be configured to be unlit dur-
ing normal operation, or to flash only when the camera is accessed. See the online help files for
more information. Go to Setup > System Options > LED settings
Amber Steady during startup, reset to factory default or when restoring settings.
Red Slow flash for failed upgrade.
Power Green Normal operation.
Amber Flashes green/amber during firmware upgrade.
Description
On the external device output terminals (A and B), there is no distinction between
positive and negative (+ and -). The terminals use a photocoupler and are electri-
cally isolated from the other internal circuitry.
The maximum load should not exceed 100mA and the maximum voltage should be
not more than 50V DC. Note: Connecting AC to the output will damage the unit.
Photocoupled Input 1. Electrically isolated from the chassis and connectors, this
input can be supplied from an external DC voltage or the DC Power Input/Output
on pins 9 (DC+) and 10 (GND).
Photocoupled Input 2. As above.
A half-duplex RS-485 interface for controlling auxiliary equipment.
This can drive the photocoupler inputs or other equipment. The output voltage level
is 3.0 V. A maximum current of 100mA can be sourced from the DC output.
