I-7565-H1/H2

Description

The following is the application structure for these two USB/CAN modules. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by the I-7565-H1/H2 Converter. These modules let users to communicate with CAN devices easily from PC with USB interface.
(1) I-7565-H1: High Performance intelligent USB to 1- port CAN bus Converter.
(2) I-7565-H2: High Performance intelligent USB to 2- port CAN bus Converter.

Application of I-7565-H1/H2

I-7565-H1 Application

2500Vrms isolation on CAN side
The CAN port of I-7565-H1/H2 is isolated with 2500Vrms. This isolation can protect the local devices from the damage signal coming from CAN network.

Watchdog inside
The I-7565-H1/H2 Watchdog is a hardware reset circuit to monitor the operation status of I-7565-H1/H2. When working in a harsh or noisy environment, the I-7565-H1/H2 may be down by the external signal. The circuit may let the I-7565-H1/H2 work continuously and never halt.

Power / Communication / Error indicator display
There are three indicators on the I-7565-H1/H2.The power indicator can help user to check whether the I-7565-H1/H2 is standby. The communication indicator is used to show whether the I-7565-H1/H2 is transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7565-H1/H2.

In order to apply the I-7565-H1/H2 to CAN network with NI LabVIEW software, we provide a LabVIEW 8.x library and demo for the purpose. It is very useful to develop the CAN-relative application in NI LabVIEW environment by using I-7565-H1/H2. It is easy to use and can help user to rapidly reduce their program development cycle. If users want to develop a LabVIEW industrial application with CAN network, the LabVIEW library and demo of I-7565-H1/H2 is very helpful.
