Most RS-232 devices don’t support device addressing, the ICP DAS I-7522D assigns a unique address to any RS-232 device installed on an RS-485 network. When the Host PC sends a command with a device address to the RS-485 network, the destination I-752N module will remove the address field, and then pass the other commands to its local RS-232 devices. The response from the local RS-232 devices will be returned to the Host PC via the I-752N module.
The ICP DAS I-7522D converter is unique as it a Master-type converter that use ICP DAS R.O.C. Patent 086674, while most other converters are a Slave-type, which cannot operate without a Host PC. In real industrial applications, users are not satisfied with Slave-type converters as they cannot be adapted to individual requirements; the ICP DAS I-7522D is an ideal solution.
