RUT204 CAN Bus Gateway

The information in this page is updated in accordance with firmware version RUTE_R_00.07.23.2.

Summary

The CAN Bus Gateway a CAN (Controller Area Network) Bus Gateway is a communication device used to connect and manage data exchange between multiple CAN networks or between CAN and other communication protocols. It acts as a bridge, router, or filter to ensure that messages move efficiently and securely across different segments of a system. This manual page provides an overview of the CAN Bus gateway page in RUT204 devices.

Status

---

Shows the current operational state of the CAN Bus Gateway.

CAN Device Configuration

---

This section allows you to configure the physical CAN device.

Field	Value	Description
Enable	off | on; default: off	Enable service.
Bit rate	integer [256..10000000]; default: 50000	Data transmission speed (bit/s).

Configuration Settings

---

You can configure network related parameters of the service connection in the Configuration settings section.

Field	Value	Description
Mode	Server | Client | Client + server; default: Server	Possible modes: Server - launches service in server mode and listens on the selected port. Client - launches service in client mode, which connects to one or several servers with the selected addresses and ports. Client + server - launches service in server and client(s) mode simultaneously.
Protocol	TCP | UDP; default: TCP	Select which protocol to use for data transmission.
Client / Client + server: Destination address	IP | Port; default: empty	Specify server address and port for client to connect to (e.g., first field for address second for port. 16 destination addresses are allowed if connect on data is not enabled).
Server: UDP: Predefined addresses	IP | Port; default: empty	Set predefined IP and port for UDP connection.
Listening port	[1..65535]; default: empty	Specify port number for server to listen.

Field	Value	Description
Use TLS/SSL	off | on; default: off	Enable TLS/SSL for secure connection.
TLS version	Support all | TLS 1.2 | TLS 1.3; default: TLS 1.2	Minimum TLS version allowed to be used.
TLS type	Certificate based | Pre-Shared-Key based; default: Certificate based	Select the type of TLS encryption.
Require certificate	off | on; default: on	Demand certificate and key from peer and verify them against certificate authority.
Certificate files from device	off | on; default: off	Choose this option if you want to select certificate files from device. Certificate files can be generated here.
Certificate file	.crt file; default: none	Upload certificate file.
Key file	.key file; default: none	Upload key file.
CA file	.ca file; default: none	Upload CA file.
Pre-Shared-Key	string; default: none	The pre-shared-key in hex format with no leading “0x”.
Identify	string; default: none	Specify the identity.

Field	Value	Description
Raw mode	off | on; default: on	Enable to transmit all data transparently.
Inactivity timeout	integer [0..36000]; default: 300	Specifies period of time in seconds, where server connection must be inactive, to disconnect client. To disable timeout input 0.
Max clients	integer [1..32]; default: 4	Specify (1-32) how many clients are allowed to connect simultaneously.
TCP echo	on | off; default: off	Enable software TCP echo.
Close connections	on | off; default: off	Close TCP connections everytime data is sent or received (might result in CAN bus data loss).
Keep alive	on | off; default: off	Enable keep alive.
Keep alive time	integer [0..32000]; default: 30	Duration until the first probe will be sent.
Keep alive interval	integer [0..32000]; default: 15	The interval between subsequent keepalive probes.
Keep alive probes	integer [0..32000]; default: 3	The number of unacknowledged probes needed to consider the connection lost.
