Introduction
1.1
Functional Description
The USB2-F-7001 and USB2-F-7101 are USB to CANbus adapters which incorporate the FTDI FT245R
USB to FIFO interface IC device. The USB2-F-7101adds optical isolation for the CAN interface. These
adapters provide a fast, simple way to CANbus devices to a host PC with a USB port. Throughout this
manual, both adapters will be identified as USB2-F-7x01 where common features are identified.
Each USB2-F-7x01 contains a small internal electronic circuit board mounted inside of a plastic case
capable of withstanding industrial temperature ranges. The FT245R datasheet, DS_FT245R, is available
at http://www.ftdichip.com. The integrated electronics include a Microchip PIC with the ECAN controller.
LEDs give a visual indication of the CANbus status.
The USB2-F-7x01 does not require a power supply. It is powered from the USB connection. The USB2-F-
7001 requires 150mA (450mA for the USB2-F-7101) and must be connected directly to a USB Host port,
or a self-powered USB hub (i.e. with an external power supply). Bus-powered USB hubs are not
supported since they cannot provide the required current.

Flexible mounting allows the USB2-F-7x01 to be used in a variety of applications, from a portable adapter
to accompany a laptop to permanent installations in industrial and commercial locations.
The enclosure incorporates a standard USB-B device connector for connection to an upstream host or hub
port. CANbus signals are available on an industry-standard DE-9P connector conforming to the CAN-in-
Automation (CiA) DS102-2 pin-out. The maximum CANbus data rate is 1Mbps.
The USB2-F-7x01 adapter requires USB device drivers, available free from http://www.easysync-ltd.com,
which are used to make the USB2-F-7x01 appear as a Virtual COM port (VCP). Communications in VCP
mode are accomplished with ASCII commands to the CAN controller. ASCII commands are listed in
Section
4.1.
Another USB device driver included with the download, the D2XX driver, can also be used with
application software to directly access the FT245R, and used in conjunction with a CAN command
Application Programming Interface (API) through the use of DLLs. The high-level API is listed in the
USB2-F-7x01 API Guide.
