9.2 Profile<br />
There are some configuration parameters for the Optolyzer in the profile CAN.INI in<br />
the executable directory of <strong>CANoe</strong>/<strong>DENoe</strong>.<br />
For each channel enter a section [OptolyzerX] in CAN.INI, where X stands for the<br />
channel which should be configured by this section.<br />
The selection of the COM port and the license key can comfortably be entered<br />
through the MOST Hardware Configuration dialog. However, the values will still be<br />
stored in CAN.INI because these are PC related settings which should not be moved<br />
to other PCs by using the configuration file on other PCs.<br />
[Optolyzer1]<br />
// Interface<br />
// 1=COM1, 2=COM2<br />
ComPort = 1<br />
// Licence number for operation without OptolyzerPro<br />
// (If Optolyzer Pro is installed with a licence for using<br />
// the OptoControl with the connected Optolyzer Box no entry<br />
is needed)<br />

9.3 Timestamps<br />
<strong>CANoe</strong> uses a resolution of 10 µs for the timestamps of events. The Optolyzer box<br />
generates only timestamps with a resolution of 1 ms, thus all shown timestamps related<br />
to MOST events have at maximum this resolution, even if shown in a higher<br />
resolution.<br />
All events received before the time synchronization could calculate a valid offset between<br />
CAN bus and MOST ring are suppressed. Therefore the first MOST frames<br />
shown in a trace window may have a timestamp several seconds after measurement<br />
start.<br />
9.4 Synchronized timestamp<br />
The unit of this timestamp is 10 µs, with 0 at the start of measurement.<br />
This timestamp is synchronized with the timestamps on the CAN bus by a software<br />
algorithm.<br />
Due to the algorithm, the accuracy of this timestamp might vary slightly, but the timestamps<br />
can be used for calculations across more than one bus system or across multiple<br />
MOST channels.<br />
Technical reasons let this algorithm work better with the spy mode of the Optolyzer<br />
box.<br />
In node mode time synchronization may be impaired by sending MOST frames from<br />
CAPL nodes.<br />
