RS-485 Connectivity (CNV-100)

Ensure connectivity of RS-485 devices! The CNV-100 enables interoperability of RS485 2-wire and 4-wire multi-point data communication networks. The CNV-100 connects 2-wire devices to 4-wire systems or 4-wire devices to 2-wire systems. LEDs flash to confirm data transmit/receive at both 2-wire and 4-wire sides.

The CNV-100 RS-485 (EIA-485) interfaces conform to the Modbus standard for RS-485 serial data communications. In general, it can be used with any protocol that adheres to the RS-485 standard operating at baud rates of 9600, 19.2k or 38.4k bps.

Reliable operation. The RS-485 2-Wire to 4-Wire Converter uses proven technology. Thousands of devices have been in operation since its introduction in 2003.

The RS-485 2-Wire to 4-Wire Converter operates automatically for any supported baud rates. No setup required. No DIP switches to set!
