I-7530 applicationIn pair connection mode, I-7530 can be used to connect PC with other RS-232 devices at the same time. I-7530 can also enable programmable RS-232 devices such as PC's, I-8411/I-8431/I-8811/I-8831 embedded controllers to be the master of a CAN network.

3000V isolation on CAN side
The CAN port of I-7530 is an isolated with 3000V isolation. This isolation can protect the local RS-232 devices from the damage signal coming from CAN network. 

Watchdog inside
The watchdog is a hardware reset circuit to monitor the operation status. When working in harsh or noisy environment, the I-7530/I-7530-FT may shut down by the external signal. The circuit may let the I-7530/I-7530-FT to work continuously and never halt.

Power and Error indicator display
There are two indicators on the I-7530/I-7530-FT.The power indicator can help user to check whether the I-7530/I-7530-FT is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7530/I-7530-FT.

Virtual CAN

There are various communication interfaces among the CAN devices like PCI CAN board, Ethernet series and RS-232 series CAN module. According to different purpose of users’ projects, the users maybe need to choice different CAN products. Because of this situation, the programmer should develop different communication program to handle different CAN device. For example, the user should develop “Socket Client” to communicate with I-7540. When using I-7530, the users need “UART” technique to communicate with it. Nowadays, ICP DAS develop the Virtual CAN technique. The Virtual CAN driver is the excellent tool for users. It transforms whole CAN devices into Virtual CAN port. And then it generates Virtual CAN port like “VxCAN 1” or “VxCAN 2”. The users could send and receive CAN message by appointing the Virtual CAN port number. The users don't need to care about what kind of CAN device which is used.
