I-7530 
RS-232 to CAN Converter |

CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent
industry devices networks and build smart automatic control
systems. The following figure shows the application architecture
for I-7530 modules. The PC can be the CAN host, monitor or HMI
to access/control the CAN device through the CAN network by
the I-7530 Converter. The programmable RS-232 device (For example:
I-8411/I-8431/I-8811/I-8831/W-8031/W-8331/W-8731 embedded controller)
can use the serial port to connect to the CAN network via the
I-7530 module. In order to use the CAN network with traditional
RS-232 devices, we provide a way to achieve this purpose. The
I-7530 is designed to unleash the power of CAN bus via RS-232
communication method. It accurately converts messages between
CAN and RS-232 networks. This module let you to communicate
with CAN devices easily from any PC or devices with RS-232 interface.
Moreover, we expand the functionalities of I-7530 for some special application. In pair connection mode, I-7530 can be used to connect PC with other RS-232 devices at the same time. The application architecture may be as follows.
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 I-7530 Watchdog is a hardware reset circuit to monitor the
I-7530¡¦s operation status. When working in harsh or noisy environment,
the I-7530 may be down by the external signal. The circuit may
let the I-7530 to work continuously and never halt.
Power and Error
indicator display
There are two indicators on the I-7530.The power indicator can
help user to check whether the I-7530 is standby or transmitting/receiving
messages. The Error indicator will be turned on when some errors
occur on the I-7530.
