Video (optional):
This interface is used for the analog Video-Input included protected camera power
supply.
Ethernet (optional):
There is an Ethernet interface (10/100 Mbit/s Base) available on the unit. This
interface may only used for the data transfer.
Power-on/off Behavior:
The OPUS A3 does not have a separate on/off key. As soon as the device is
supplied with the necessary voltage via terminal 30 (battery plus), terminal 31
(battery GND) and terminal 15 (ignition), it will start to boot. In order to decrease
boot time the device supports power modes with which you can put the device in a
sleep mode before it powers down.
When ignition voltage is removed, the device will switch to low-power-mode (see
C/C++ Developer Guide ). After a time frame that can be configured (default time is
60 sec) the device will move one more step down to sleep-mode. After another 60
seconds (default time) the unit will fully switch off. As soon as terminal 15 is switched
on again the unit will go back to on-mode in full operation.
Power Mode current at 13.5 V DC current at 27 V
On 430 mA 240 mA
Low-power 160 mA 90 mA
Sleep 90 mA 55 mA
Off < 3 mA < 3 mA
