Wireless CAN Bus Bridge with USB Interface
ESD Electronics announced its CAN-CBX-AIR/3, a wireless CAN Bus bridge with USB interface. The bridge meets the requirements according to ETSI EN 300 328 V.2.0.20 (RED) standard. Like the previous CAN-CBX-AIR/2 version, the CAN-CBX-AIR/3 module works with a carrier frequency of 2,4 GHz in the ISM band. The transmission distance is up to 200 m (~ 600 ft) line-of-sight (LoS). Compared to WLAN or Bluetooth, it offers reduction of connection setup time and latency of the CAN transmission, said the company.
The bridge supports data exchange between CAN networks even at different bitrates. This can be used e.g. to get access to CAN modules installed at turning machine parts via a point-to-point connection. USB is used to configure the bridge. But beside this - CAN-CBX-AIR/3 enables a PC to communicate CAN data via USB to a remote CAN-CBX-AIR/3 for e.g. service and maintenance.
The bitrate is set by a rotary switch at the module. Other functions can be configured via the integrated USB interface and the supplied Windows software. These software can be used for CAN monitoring, too. Four LEDs show the operating status of the wireless connection and the CAN communication.
- Up to 200 m transmission range
- Linking CAN nets with different bit rates
- CAN-telegram filtering
- Configuration and diagnostics via USB interface with Windows® based configuration tool
SAE J1939 to Bluetooth Gateway With 9-Pin Deutsch Connection Cable
The jCOM.J1939.BT gateway is a high-performance, low-latency, wireless vehicle network adapter for SAE J1939 applications. It allows any host device with a Bluetooth COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network. An SAE J1939 cable, suited for a 9-pin Deutsch connection, is included with the gateway.
The gateway supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.
