Chapter 2 Safety Instructions
2.1 Supply and Synchronization
When concatenating OptoLyzer MOCCA devices one of the two Sync/Power connectors is intended
to be used for the power supply and the other for cascading the OptoLyzer MOCCA device by using
the optional SYNC cable V3.
During cascading, caution has to be taken, since the first device in the chain can take the maximum
current of 3 A. Do not cascade more than eight devices in chain.
For all setups either a fuse of max. 4 A in the supply cable to the first device or the use of the current
limitation of the laboratory power supply is mandatory.
2.2 Relay
The Relay feature of the device is designed to switch other 12 V powered devices. The capability is
limited to 5 A at 16 V maximum. Always use core cable ends of appropriate length and diameter to
prevent unintended connections. Lengths and diameters depend on country-specific technical
specifications. Section 1.3, "Overview OptoLyzer MOCCA Family," on page 7 informs about which
device variant of the OptoLyzer MOCCA supports the Relay feature.
Figure 2.1 Relay Circuitry
2.3 Restrictions in Operation
The OptoLyzer MOCCA device integrates temperature sensitive components. Therefore do not cover
the device with any objects. Covering disables the passive cooling. Make sure to allow enough airflow
to the OptoLyzer MOCCA device, when the device is assembled. Do never place the running
OptoLyzer MOCCA device in a closed case or box. Do not stack any OptoLyzer MOCCA devices.

Chapter 4 Introduction
The OptoLyzer MOCCA compact FD device is an out of the box automotive bus interface, combining
most of the current automotive field buses. The device features e.g., simulation via PC or can be used
as an analyzing device for the different automotive bus systems.
Due to its PC compatible connections including USB 2.0 and 10/100 Mbit/s Ethernet, it is easily
possible to control the embedded OptoLyzer MOCCA device software from the PC including
monitoring, tracing, and logging of data exchange over the different field bus systems. The OptoLyzer
MOCCA device provides comfortable spy and stress functionalities when used within a MOST network.
The OptoLyzer MOCCA compact FD device supports the bus systems CAN, CAN FD, LIN, FlexRay
or MOST network (speed grade 150). Refer to Section 1.3, "Overview OptoLyzer MOCCA Family," on
page 7 for details.

4.3 Properties of Supported Bus Systems
The OptoLyzer MOCCA device is intended to be used as stimulation, test and analysis device for
automotive field buses with DUTs connected to them. Therefore the design is constrained to ensure
the behavior to be as passive as possible.
4.3.1 CAN
The accuracy of CAN time stamps is 500 µs (or better).
4.3.1.1 High-Speed Transceiver
High-Speed CAN bus systems according to ISO 11898-2:2015 [2] are terminated with 120 Ωat each
end. Therefore the OptoLyzer MOCCA device does not terminate the bus. Transmission speed ranges
from 33.333 kbits/s to 1 Mbits/s.
4.3.2 CAN FD
CAN FD bus systems according to ISO 11898-2, ISO 11898-2:2016 [2] and SAE J2962-2 are
terminated with 120 Ωat each end. The OptoLyzer MOCCA compact FD device can be used at the
end of the bus system (in this case plug in the optional termination resistor, Section 1.2, "Scope of
Delivery," on page 6) or somewhere between the ends (in this case don’t plug in the optional
termination resistor). The accuracy of CAN FD time stamps is 1 µs. The OptoLyzer MOCCA compact
FD device supports up to 2 Mbits/s for each CAN FD channel in parallel. It is designed to operate with
up to 64 byte payload. CAN FD requires a prescaler (data phase) of 1 or 2 for 500 kbit/s and above
in case a custom bit rate (named StartCanFdExt in ABI Framework or ConfigureExtended in the K2L
Bus Framework) is used.
4.3.3 FlexRay
The termination of a FlexRay bus depends on the bus topology. Two terminations are mandatory in
each active branch. The OptoLyzer MOCCA device can be installed in various topologies. Therefore
a termination is not implemented in the device. Thus the terminations have to be realized in a different
way. In addition, the OptoLyzer MOCCA device does not act as a bus guardian.
The OptoLyzer MOCCA device provides one FlexRay interface and is able to switch from sleep mode
to wake-up mode stimulated by the FlexRay bus. The OptoLyzer MOCCA device is capable of
transmitting up to 10 Mbit/s as per "Electrical Physical Layer Specification Version 2.0" [1]. The
accuracy of FlexRay time stamps is 500 µs (or better) for the static part of the schedule.
4.3.4 LIN
Both LIN master and LIN slave functionality are supported. The accuracy of LIN time stamps is 1 µs.
The OptoLyzer MOCCA device supports a maximum transmission speed of 20 kbit/s.
4.3.5 MOST
The OptoLyzer MOCCA compact FD designed for a MOST150 network (cPHY) has a fixed clock mode
of 48 kHz. OptoLyzer MOCCA compact FD devices have an INIC, a SpyNIC for MOST and a
StressNIC for MOST on-board. If desired, the StressNIC for MOST can be added to the ring via
software. The accuracy of INIC MOST network time stamps is 500 µs (or better) for the node and 1 µs
for the spy.

K2L USER MANUAL
When analyzing data e.g., when interpreting an acknowledged code, it is important to know how the
chips (INIC, SpyNIC for MOST, StressNIC for MOST) are arranged inside the OptoLyzer MOCCA
compact.
Figure 4.2 Order of MOST Network ICs
4.3.5.1 MOST150
Data exchange between the OptoLyzer MOCCA compact FD and the embedded OS81110 INIC is
realized by I2C. Right now control messages are supported.
4.3.5.2 SpyNIC for MOST
The OptoLyzer MOCCA compact FD has an appropriate SpyNIC for MOST on-board. The SpyNIC is
spying control, packet, and allocation messages. The accuracy of SpyNIC time stamps is 1 µs. In the
MOST150 network four synchronous/isochronous channels can be spied all the time.
4.3.5.3 StressNIC for MOST
The OptoLyzer MOCCA compact FD has an appropriate StressNIC for MOST on-board. The StressNIC
is supporting dedicated use cases for simulating some common network error situations (e.g., activity,
lock stress, buffer full simulation, etc.). By default the StressNIC for MOST is electrically bypassed but
can be enabled by appropriate software (e.g., ATS) (see Figure 4.2 on page 15).
4.3.6 Ethernet
Auto MDIX is supported, therefore the LAN interface can connect via straight and crossed patch
cables. The physical layer 100Base-TX is supported. Thereby the MAC address of the Ethernet
controller has a unique address. The accuracy of Ethernet time stamps is 500 µs (or better).
4.3.7 Sleep Mode
The OptoLyzer MOCCA device is able to scan the four CAN buses (1, 3, 4, 5 but not CAN FD) in
sleep mode and if stimulated to switch from sleep mode into wake-up mode. In addition, the OptoLyzer
MOCCA device can be woken-up via FlexRay, LIN or ECL. For controlling the sleep mode software
has to be developed by the customer on a PC.

INTERFACE SYMBOL DESCRIPTION
Analog Audio OUT The OptoLyzer MOCCA compact FD device provides an analog audio
out interface (a stereo headphone output). It has a 3.5 mm jack plug.
Output Power: Po, Max, Rms = 1.4 mW (at R = 16 Ω, Vout = 150 mVRMS)
The bandwidth (16 bit mono/stereo or 24 bit stereo) specified for this
interface is also used for the S/PDIF OUT and vice versa. Rx and Tx
transmission must cover the same bit number per channel. Refer to the
S/PDIF description inclusive examples in Table 5.3 on page 20.
ECL ECL can be used to start a diagnosis process over the MOST network
according to different ECL implementations. For the pin out refer to
Section 6.9, "Trigger/ECL," on page 26.
