I-7540D-WF CR: Bộ chuyển đổi CAN sang Ethernet/Wi-Fi


• IEEE 802.11b/g compliant
• Wireless data transmission via WLAN
• Two different operation modes: infrastructure and ad-hoc
• point to point or point to multi-points connection via wireless LAN
• Supports WEP, WPA and WPA2 encryption for wireless LAN
• CAN 2.0A/2.0B compliant
• Connect CAN networks via a WLAN bridge
• Communication efficiency: one-way is up to 700 fps (client->server, server->client),two-way 350 fps (client<=>server)
• Wireless transmission distance: up to 100 meters


The I-7540D-WF supports the wireless transmission of CAN data between a CAN network and a WLAN network according to the 802.11b/g standard. It provides CAN to WLAN converter functionality together with wireless transparent transmission on the CAN network. The I-7540D-WF is highly suitable for connecting mobile (e.g., vehicles or machines) or stationary CAN networks and is often used in short ranges up to 100 m. Using an appropriately configured router, CAN data can be determined to pass or filter from the CAN networks to the Ethernet. The wireless connection that is established between two I-7540DWF units can be used instead of a cable, and enables the connection of CAN networks that would otherwise be difficult to link such as rotational machineries.
