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 />

Licence=89AB0123CDEF4567<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 />
