I-7540D-WF CAN to Wi-Fi Converter User’s Manual (Ver. 2.0, Jan/2012) ------------- 5
1. Introduction
The I-7540D-WF supports the wireless transmission of CAN data
between various CAN networks or a CAN network and a WLAN network
according to the 802.11b/g standard. It is highly suitable for connecting
mobile (e.g., vehicles or machines) or stationary CAN networks and is
often used for short ranges up to 100 m.(TCP data protocols are available.)
Using an appropriately configured router, CAN data can be transmitted
over the Internet. There are two operating modes in the I-7540D-WF: the
access point mode and the ad-hoc mode. In the access point mode, the
data connection takes place over one or several WLAN access points that
are often part of the company's internal IT infrastructure. In the ad-hoc
mode, a direct connection is established between a single I-7540D-WF
device and a PC or laptop (with an integrated WLAN interface), or with a
second I-7540D-WF device. In this way, the I-7540D-WF can be used as a
CAN diagnosis interface. The wireless connection that is established
between two I-7540D-WF 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 machinery.
