OP-SB88 FlexRay Communications Expansion Kit
Outline
The OP-SB88 is an expansion kit that allows monitoring of FlexRay communications on up to two channels in real time.
The kit incorporates a monitor function that does not require complicated parameter settings, and a simulation function with which the OP-SB88 works as a FlexRay communications node to transmit and receive data, thus powerfully supporting the initial development.
The filter function and high-capacity memory greatly shorten the analysis time of trouble.
Furthermore, it incorporates a simultaneous measurement function for external signals, which makes it possible to investigate the relationship between the operation of peripheral devices and communications data.
Features
10Mbps, 5Mbps, 2.5Mbps Communication Speed
Supports 10Mbps, 5Mbps, 2.5Mbps which are the standard speed of FlexRay communication.Easy Monitoring
It enables to measure FlexRay data only by choosing a communication speed without setting about 50 parameters particular to FlexRay.Dual Controller
Two FlexRay controllers equipped with OP-SB88 act for the leading cold start node and following cold start node that are necessary for FlexRay communications. It enables to evaluate the module of the non-cold start node that does not perform cold start.FlexRay Transceiver, TJA1080
It has TJA1080 from NXP Semiconductors which is the world's first FlexRay transceiver.Monitor Function

The filtering of the reception frame can be set for frame ID, each indicator bit, and cycle counter in the frame header.
Simultaneous Measurement of External Signal
It measures/records signal voltage of target device connected to the external terminal of analyzer in analog and digital value when receiving a frame.< analog value display >
< digital value display >
Display Specific Data on Pointed Line
It displays the arbitrary data (Frame header, Payload) of specific frame in the pointed line and helps to analyze the larger amount of FlexRay data.< Specific Data on Pointed Line Setting >
< Display Specific Data on Pointed Line >
Event Counter Display
< event counter display >
It displays the number of the frame reception of every channel, the number of matched data triggers, the number of the outbreak of each error. The appearance of the specific frame can be calculated by combining with the trigger function.
Trigger Function
It can set the data trigger for Payload data, frame ID, each indicator bit, and cycle counter in a frame. It also has the error trigger for communication error, and the external trigger for external input condition.< list of trigger setting >

Simulation Funcition
Automatic Frame Transmission
Frame transmission of passive frame for media access with time trigger transmits frame data registered beforehand.< list of automatic frame transmission >
< payload setting display >
(Example 1)
Transmit frames when cycle counter is odd by specifying the cycle counter function.(Example 2)
Transmit the arbitrary Payload for each cycle counter (0 to 63) by using the pattern table.(Example 3)
Change the part of Payload by using the sweep function.< pattern table>
< sweep setting >
Event Transmission of Frame
Frame transmission function is made assuming the transmission of active frames for media access in event driven mode.It can switch the transmission of frames (in the case of active frames) and Payload data by key operation. It transmits at most 16 Payload data for every frame.

File Saving
A CF card (option) can store measured results and settings.It enables to save the simulation settings including over 50 parameters particular to FlexRay. It contributes to improvement of the fieldwork in the demanded of quick correspondence.
Print Function
It can print all measured results and the simulation settings.In addition, it is possible to load them as the plain text format in a CF card to use in a PC.
