UMAX141200. Wi-Fi to CAN Converter. Version 1
Page: 32-44
In this configuration, the converter is directly connected to the monitoring device through the
Wi-Fi wireless link. The Wi-Fi to CAN converter acts as an AP and the IP device – as a STA.
The same configuration is used for the initial converter setup, see Configuration section.
The CAN monitoring device should use an Axiomatic proprietary communication protocol to
convert CAN messages into IP datagrams. This protocol is the same as being used in the
Axiomatic Ethernet to CAN converter, p/n AX140900.
Axiomatic provides CAN-ENET Software Support Package (SSP), p/n AX140910, for
interfacing with the converter and performing all necessary data conversions. The SSP is
downloadable from
www.axiomatic.com
, log-in section. Due to differences in the
Health Status
coding between Ethernet to CAN and Wi-Fi to CAN converters, SSP version 2.0.0 or higher
should be used.
All Axiomatic PC software tools supporting the Ethernet to CAN converter also support Wi-Fi to
CAN converter by default; the user can select
Ethernet to CAN Converter
in configuration
Options
to communicate with the Wi-Fi to CAN Converter.
The Axiomatic
Electronic Assistant
®
(EA) can communicate with both: Ethernet to CAN and Wi-
Fi to CAN Axiomatic converters starting from version 5.11.82.0, and the
CAN Assistant –
Scope
and
CAN Assistant – Visual
support the converters starting from version 3.0.0.
6.3 Wireless CAN Station
In this configuration, a converter in STA mode is connected to a third-party AP and then all
communication with the converter goes through this AP, see Figure 28.

Figure 28. Wireless CAN Station
There can be several converters connected to one AP. The AP can be connected to IP devices
through a LAN or over the cloud.
This configuration is the most versatile. It practically has no limits on the number of converters
and IP monitoring devices and the distance between the devices and the converters.
