1. Introduction
I-7565-H1 and I-7565-H2 are the high speed intelligent USB to CAN
converters with one and two CAN channels separately. They provide
faster CAN bus communication performance than I-7565. Both I-7565-H1
and I-7565-H2 support CAN2.0A/2.0B protocol and different baud rates
from 5 Kbps to 1 Mbps. The important feature of I-7565-H1/H2 is to
support the user-defined baud rate function no matter what the baud rate
is. When connecting I-7565-H1/H2 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-7565-H1/H2. 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 these two USB/CAN
modules :
(1) I-7565-H1: High Speed intelligent USB to 1- port CAN bus Converter.
(2) I-7565-H2: High Speed intelligent USB to 2- port CAN bus Converter.

2.4 Terminator Resistor Settings
According to the ISO 11898 specifications, the CAN Bus network
must be terminated by two terminal resistors (120
Ω) for proper operation,
as shown in the below figure.
Figure 2-6: Terminal Resistor
Therefore, the I-7565-H1/H2 module supplies a jumper for users to
active the terminal resistor or not. If users want to use this terminal resistor,
please open the I-7565-H1/H2 cover and use the
JP3 for I-7565-H1 / JP3,
JP4 for I-7565-H2 to activate the 120Ω terminal resistor built in the module,
as the Figure 2-7. Note that the default setting is active.

2.5 Init / Normal Dip-switch
On the back of the I-7565-H1/H2 module, there is a dip-switch used
firmware operation or firmware updating of the module. The following
for
steps show how to use this dip-switch.
2.5.1 Firmware Update Mode
Please set the dip-switch to the “Init” (Initial) position like Figure 2-9.
Then the I-7565-H1/H2 will work in the “
Firmware Update Mode” after the
power of the module has been turned on again. In this mode, users can
update the firmware of the I-7565-H1/H2 module via USB and the module
will become a “USB Mass Storage Device” and also shows a folder like
Figure 2-10 automatically.

Users just need to execute “Firmware_Update_Tool.exe” and follow
I-7565-H1/H2 High Speed USB/CAN Converter User’s Manual (Ver 1.1, Nov/2009) ------------- 11
the below steps to complete the firmware updating process.
[1] Choose “USB” interface and “USB Disk”.
[2] Click “Browser” button to choose firmware file. (like I7565H1_v1.01.fw)
[3] Click “Firmware Update” button to start firmware updating process.
The result will show in “Firmware Update” field.

http://ftp.icpdas.com/pub/cd/fieldbus_cd/can/converter/i-7565h1h2/software/tool
2.5.2 Firmware Operation Mode
In operation mode, users need to set the dip-switch to the “Normal”
position like Figure 2-12 and turn the power off then on again so that the I7565-H1/H2 can run in the operation mode. In this mode, users can send /
receive CAN messages via PC USB port.

2.6 LED Indication
There are three LEDs provided to indicate to users what situation the
I-7565-H1/H2 is in. The following is the illustration of these three LEDs
and the position of these three LEDs shows as Figure 2-12.
(1) PWR LED :
It is used to help users to check whether the I-7565-H1/H2 is standby.
If the module is working in “firmware operation” mode, the PWR LED is
always turned on. However, when the module is working in the “firmware
updating” mode, the PWR LED will flash approximately once per second.
(2) RUN LED :
It is used to show whether the I-7565-H1/H2 is transmitting/receiving
CAN messages. The RUN LED will flash whenever a CAN message is
sending or receiving. In I-7565-H2, the RUN LED is shared by CAN1 port
and CAN2 port.
(3) ERR LED :
It is used for demonstrating an error that has occurred. The ERR LED
is normally turned off when the module works in a good condition. When
the Bus-Off error happened, the ERR LED will always turn on until the
Bus-Off condition disappeared. If the CAN/USB buffer built in I-7565H1/H2 overflows or CAN message can’t be sent out successfully, then the
ERR LED will flash continuously. In I-7565-H2, the ERR LED is shared by
CAN1 port and CAN2 port.

2.7 Cable Selection
The CAN bus is a balanced (differential) 2-wire interface running over
either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or
Ribbon cable. The CAN-L and CAN-H Wire start on one end of the total
CAN network that a terminator of 120 Ohm is connected between CAN-L
and CAN-H. The cable is connected from CAN node to CAN node,
normally without or with short T connections. On the other end of the cable
again a 120
lines. How to decide a cable type, cable length, and terminator depends
on the baud rate in the CAN bus network, please refer to the following
table 3.
Ω(Ohm) terminator resistor is connected between the CAN

Note: The AWG means a standard method used to measure wire. The
numbering system works backwards from what people would think, the
thicker (heavier) the wire, the lower the number. For example: a 24AWG
wire is thicker/heavier than a 26AWG wire.
