Service interface:
On OPUS B2/B2 Plus there is a service interface available. This interface serves
Topcon internal service use only.
Please do not remove the protection cap of service interface!
OPUS B2/B2 Plus may only be used with factory closed protection cap otherwise
Topcon Electronics GmbH is no liable for any damage or misfunction.
Power-on/off behavior:
OPUS B2/B2 Plus can be switch on/off by the power supply directly.
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.
