Main connector:
The following interfaces are available:
Power supply and ignition input
2 x CAN-Interfaces according to ISO/DIS 11898
RS232-Interface
USB full speed
4 configurable analogue/digital inputs (optional), where input 1 work with
frequency 1-10 kHz and may also be used as frequency input, inputs 2-4
works with max signal frequency of 50Hz
3 digital outputs (option)
Audio-Out (option)
Video:
This interface is used for the analog Video-Input including protected camera power
supply as well as a digital camera control output (open drain). There is 1 video
interface available on the basic option unit and 3 video interfaces available on the full
option unit.
Ethernet:
There is an Ethernet interface (10/100 Mbit/s Base T) available on the unit. This
interface may only be used for data transfer.
Power-on/off behavior:
The OPUS A8 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.

Do not unplug clamp 30 from power supply on running unit.
Power supply interruption on clamp 30 may cause data
corruption and loss.
