Introduction

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

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.
