KD485-STD-422-422

RS422/485<>RS422/485 port isolator

The KD485 is a multi-purpose interface converter designed to satisfy a wide range of industrial datacomms requirements. One common application is the connection of multi-dropped RS485 devices to an RS232 system. Most currently available converters require the RS232 device to control its RTS signal to enable/disable the RS485 driver, but some RS232 systems do not have this capability.
The KD485-ADE avoids RTS control: Another application is a multi-drop connection of non-addressable RS232/422/20mA devices, to enable to be conveniently polled from a single RS485 Master device. The KD485-ADE can act as an “addressable adapter”.
Many projects involve the interconnection of equipment which is mutually incompatible. The KD485-PROG can be programmed – in ANSI C - to convert virtually any async industrial automation protocol into any other.
