1. Introduction
I-7565M-HS is a high speed USB to CAN converter with two CAN channels. It
improves the transformation speed of other I-7565 series, and allows receiving max.
15000 standard 2.0A CAN frames per second. I-7565M-HS support CAN2.0A/2.0B
protocol and different baud rates from 10 kbps to 1000 kbps. The important feature of
I-7565M-HS is to support the user-defined baud rate function no matter what the baud
rate is. When connecting I-7565M-HS to PC, PC will load the relevant device driver
automatically (hot plug & play). Therefore, users can make data collection and
processing of CAN Bus network easier and quicker by applying I-7565M-HS. The
application fields can be CAN Bus monitoring, building automation, remote data
acquisition, environment control and monitoring, laboratory equipment & research,
factory automation, etc.
The following is the application structure for the USB to CAN module. The PC can
be the CAN host, monitor or HMI to access/control the CAN devices through the CAN
network by the I-7565M-HS Converter. The module let users to communicate with CAN
devices easily from PC with USB interface.

2.3. Pin Assignment
The pin assignments of 8-pin terminal block connector of I-7565M-HS is shown in
the following tables.
Table 2-1 Pin Assignment
Pin No Name Description
1 CAN_GND CAN ground of CAN1 port
2
CAN_L
CAN_Low bus line of CAN1 port.
3 F.G. Frame Ground.
4 CAN_H CAN_High bus line of CAN1 port.
5 CAN_GND CAN ground of CAN2 port
6 CAN_L CAN_Low bus line of CAN2 port.
7 F.G. Frame Ground.
8 CAN_H CAN_High bus line of CAN2 port.
Electronic circuits are always influenced by different levels of Electro-Static
Discharge (ESD), which become worse in a continental climate area. F.G. provides a
path for conducting the ESD to the earth ground. Therefore, connecting the F.G
correctly can enhance the capability of the ESD protection and improve the module’s
reliability.
Wiring of F.G. is not necessary; users can modify the configuration of wiring
according to real applications.

2.5. Terminal Resistor Setup
In order to minimize the reflection effects on the CAN Bus line, the CAN Bus line
has to be terminated at both ends by two terminal resistors as in the following figure.
According to the ISO 11898-2 spec, each terminal resistor is 120Ω (or between
108Ω~132Ω). The bus topology and the positions of these terminal resistors are shown
as following figure.
Figure 2.4 CAN Bus network topology
Each I-7565M-HS includes one build-in 120Ω terminal resistor for CAN1/CAN2
ports, users can decide if it is enabled or not. The DIP switch for terminal resistor is
under the top side.
Figure 2-5 Location of Terminal Resistor DIP Switch of I-7565M-HS
The following DIP switch statuses present the condition if the terminal resistor is
active (default) or inactive.
