Serial Node RS-232 to RS-422/485 + Addressable - Model: IC-485AD

E-mail Print

Model: IC-485AD

- Able to assign address
- Able to transceive in different baud rates with else RS-232/422/485

This Serial Node RS-232 to RS-422/485 Converter + Addressable is an intelligent RS-485/422 to RS-232 converter it is designed for connecting RS-232 devices to RS-485/422 network and other RS-485/422 devices.

Most widely used computer systems, PLCs, and measuring equipment and industrial devices, its transmission speed, communication distance, especially the network ability is limited due to unbalanced transmission. The converter solves this problem, so you can easily build a RS-485/422 multi-drop network with your RS-232 device address assignment for each to communicate more easily.
