Mitsubishi's FX-485ADP communication adapter is an integral component for enhancing communication in industrial automation systems. This adapter is designed specifically with an RS-422/485 interface, facilitating robust communication in half-duplex mode. Its protocol is structured to manage exclusive communication effectively between connected devices.

This adapter’s synchronization method is based on start-stop synchronous principles, allowing distinct transmission protocols. Users can select baud rates from a wide range: 300, 600, 1200, 2400, 4800, 9600, and 19200 bps, thereby tailoring communication to match application needs. The device supports a configurable station number, allowing adjustments from 0 to 15 for a maximum of 16 stations.

Data transmission utilizes a flexible format, which includes a start bit, a choice between 7 or 8 data bits, an optional parity bit, and either one or two stop bits. Robust error detection techniques, encompassing both parity checks and sum checks, help maintain data integrity. Additionally, timeout settings can be modified from 10 to 2,550 milliseconds to accommodate various operational requirements.

The FX-485ADP supports maximum cable lengths of 500 meters for RS-485 and RS-422 interfaces, while RS-232C can extend up to 15 meters, providing flexibility in installation layouts. It requires a power supply of 24V DC ±10%, drawing a maximum of 50 mA externally, and features an option for 5V DC with a draw of 30 mA from a PC.

For added safety, the adapter incorporates a transformer for power isolation and utilizes a photo-coupler for signal isolation, ensuring reliable operation. The device withstands vibrations in the range of 10 to 55 Hz with a maximum displacement of 0.5 mm, maintaining performance under considerable conditions, rated up to 2G for 2 hours in three axes.

This adapter functions effectively in ambient temperatures from 0 to 55°C and can be safely stored in conditions ranging from -20 to 70°C. With a humidity tolerance of 35 to 85% RH (non-condensing), the FX-485ADP is well-suited for the diverse environments found in industrial operations.
