Product Description

The jCOM.CAN.BTS is a CAN Bus and OBD-II scanner device with Bluetooth connection. It scans user-defined CAN message frames and transmits them per Bluetooth to a PC or Android phone or tablet (A BLE - Bluetooth Low Energy - version is in planning to support communication with iOS devices as well). The hardware is based on a generic design that allows a multitude of applications with the support of optional electronic components and corresponding firmware.

The input power (7 VDC to 36 VDC to suit a great range of applications, including vehicles) and the CAN Bus / OBD-II connections are provided per DSUB-9 connector according to CiA recommendations. An additional RS232 port is used for setting up the scanner, e.g. CAN Bus baud rate, message ID length, and up to 100 message filters. The CAN Bus message frame is translated into an ASCCI string for easy readability and processing.

Serial Interfaces

Details of the RS232 and CAN ports are described here. 

RS232

The RS232 interface is used for the device setup and on-site firmware upload, using an RS232 to USB cable. We are working in enhancements of the firmware functionality and we will post updates of the firmware on this product page.

RTS and CTS are not connected. CTS is always held in the ready state. 

CAN Port

The CAN port has an on-board 120Ω (0.5W) termination resistor. This termination resistor can be connected or disconnected via an on-board slide switch.

CAN Bus Termination Resistor

The jCOM.CAN.BTS device comes per default with a 120 Ohm termination resistor activated. To deactivate the resistor, open the enclosure and locate the DIP switch as indicated in the following image.

Device Setup

An additional RS232 port is used for setting up the scanner, e.g. CAN Bus baud rate, message ID length, and up to 100 message filters. A terminal program under Windows or Linux can be used for the setup as demonstrated in the following image:

As an example, the CAN Bus baud rate is set by hitting 'b' and then choosing the desired bitrate:

All parameters can be saved permanently onto the onboard SD card.

The CAN Bus message frame is translated into an ASCCI string for easy readability and processing. The following shows another terminal program connected to the Bluetooth COM port:
