Functional Overview​

The product provides the following capabilities.

MicroPeckerX InstaGW (MicroPeckerX main unit)​

No.	Function	Description
1	CAN/CAN FD communication (2 channels)	Provides two-channel CAN and CAN FD communication.
2	Stand-alone operation	Operates without a PC by supplying power from a mobile battery or similar source.
3	Immediate gateway operation	When the configured channel, ID, and DLC frame is received, instantly retransmits a frame with the same ID on the other channel using the predefined protocol for that channel.
4	Normal gateway operation	When a frame that matches the configured channel, protocol, ID, and DLC is received, transmits a frame with the specified protocol and DLC on the opposite channel. The transmission timing can be offset.
5	Periodic transmission	Periodically transmits frames with the specified channel, protocol, ID, DLC, and data. Alive counters and checksums can be inserted into the payload.
6	ID filtering	Forwards only frames that match the specified IDs from one channel to the other channel.

Configuration software (PC software for MicroPeckerX InstaGW)​

No.	Function	Description
1	Gateway setting file import	Reads the Excel-format gateway setting file that defines gateway and periodic transmission parameters for MicroPeckerX.
2	Gateway setting write	Writes the imported settings from the gateway setting file to the MicroPeckerX unit.
3	Gateway setting readback	Reads the configuration currently stored on the MicroPeckerX unit.

System Configuration Diagrams​

Illustrations of the system configuration.

Configuring the gateway from a PC​

Use a Windows PC to write the contents of the gateway setting file to the MicroPeckerX.

Using the gateway features​

Gateway communication is performed between the CAN buses (Bus A, Bus B, etc.) based on the contents of the setting file.

Connecting the Equipment​

Configuring the gateway from a PC​

Connect MicroPeckerX to the USB port of the PC using the supplied USB cable.

Only the USB port on the left side can be used. Do not remove the cap on the right side.

Using the gateway features​

Connect each channel to the target CAN bus using the included CAN 2-channel D-sub cable. MicroPeckerX operates stand-alone during gateway operation, but the main unit still requires power from the USB port.

D-sub Pin Assignments​

D-sub pin assignments are as follows.

Terminology​

Definitions of terms used in this guide are shown below.

Term	Description
CAN	Abbreviation for Controller Area Network, a communications protocol developed for in-vehicle networks and standardized as ISO 11898.
CAN FD	Abbreviation for CAN with Flexible Data-rate. An extension of CAN that enables faster transmission and larger payloads. Standardized as ISO 11898-1:2015.
MicroPeckerX	Collective name for the hardware system equipped with in-vehicle communication interfaces. It is used together with applications for data acquisition, analysis, and more.
Arbitration	The identifier (ID) field at the start of a CAN frame. When multiple nodes request to transmit simultaneously, the ID determines the priority and controls bus access.
Payload	The data field within a CAN frame. This is where the raw signal values are stored. Up to 8 bytes (CAN) or 64 bytes (CAN FD) can be transmitted.
Ch	Abbreviation for Channel. Refers to a physical or logical communication path on the CAN bus. MicroPeckerX supports multiple channels (for example, Ch1-1, Ch1-2) that operate independently.
GW	Abbreviation for Gateway. A device or software that relays data between networks using different communication protocols.
Gateway setting file	Excel (xlsx) file that defines the configuration for operating MicroPeckerX as a gateway device.
