There are many RS-232 devices in industry applications. Nowadays it becomes important to link all those RS-232 devices together for automation & information. Usually those RS-232 devices are far away from the host-PC & widely distributed in the factory. So it is not a good idea to use multi-serial cards to connect all these RS-232 devices together. Our I-752N series products can be used to link multiple RS-232 devices by single RS-485 network. The RS-485 is famous for it's easy maintenance, simple cabling, stable, reliable and low cost.
Onboard 1 Kb Queue buffer
The ICPDAS RS-232/422 Converter I-7522D modules are equipped with a 1Kb queue buffer for its local RS-232 device. All input data can be stored in the queue buffer until the Host PC has time to read it. These features allow the Host PC to be linked to thousands of RS-232 devices without any loss of data.
3000 V isolation on RS-485 side
COM2 of the ICPDAS RS-232/422 Converter I-7522D modules is an isolated RS-485 port with 3000V isolation, which will protect the local RS-232 devices from transient noises coming from the RS-485 network.
Self-Tuner ASIC inside
The interned ICPDAS RS-232/422 Converter I-7522D Self-Tuner ASIC for the RS-485 port can auto detect and control the send/receive direction of the RS-485 network, meaning that there is no need for application programs to be concerned about direction control of the RS-485 network.The advanced technology which makes this possible is covered.
Can be used as Addressable RS-485 to RS-232 Converter
Most RS-232 devices don't support device addressing. The ICPDAS I-752N series 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.
Master-type Addressable RS-485 to RS-232 Converter
ICPDAS RS-232/422 Converter I-7522D products are unique. In that they are Master-type converters which use our R.O.C. Patent086674, while most other converters are Slave-type, which are helpless without a Host PC. In real industrial applications, many users are not satisfied with Slave-type converters as they cannot be adapted to individual requirement.
The powerful I-752N series analyzes the local RS-232 devices, DI and DO without the need for a Host PC. Refer to Applications 5~9 for more information in the manual.
Can be used as RS-485 to RS-232 Device Server
The Device Server is an appliance that network enables any device with a serial communication port. Our Intelligent Communication Controllers allow those devices to become connected to the RS-485 network If the user wants to use Ethernet work, he can choose I-7188EN series products.
