    Description

    The product comes with multiple Part Numbers, specifically 779892-01, 779892-02, and 779892-03, designed to cater to diverse needs and applications. It features a 4-Port, RS485/RS422 interface, providing versatile connectivity options for various devices.

    With a Maximum Baud Rate of 3.6864 Mbps, it ensures high-speed data transmission, making it suitable for applications that require rapid data exchange. Additionally, the product is equipped with Data Line ESD Protection of ±15 kV, offering robust protection against electrostatic discharges that could potentially harm connected devices.

    The device supports a Maximum Cable Length of 1.2 km (4,000 ft.), enabling extended reach for distant connections without compromising signal integrity. It has a low Power Consumption (Active Mode) of only 0.5 Watts (max), making it an energy-efficient choice for continuous operation. Furthermore, in Standby/Sleep Mode, it consumes a mere 50 µWatts (max), further emphasizing its energy efficiency.

    For applications that require multiple connections, the Power Consumption (4-port module) is 3.5 Watts (max), drawing power from an +8 to +28 VDC external power supply. This ensures that even with all ports in use, the device maintains efficient power usage. The module also features Port-to-Earth Ground Isolation of 60 VDC continuous and can withstand isolation up to 1000 Vrms, providing additional safety and stability in electrical terms.

    The Connector Type includes a Four-position, female pigtail; DB-9 male front panel connector, offering flexibility in connectivity options. Despite its robust features, the device maintains a lightweight profile at only 5.4 oz., making it easy to handle and install.
