Introduction
The VPort 704 series modular industrial multi-service gateways come with 3 built-in Gigabit ports, 3 10/100 Mbps fast Ethernet ports, and 4 slots for installing Ethernet, serial, or power interface modules. The 4 slots accept a versatile assortment of communications modules, including an IP video encoder (VPM-7304), serial-to-Ethernet module (VPM-7704), and other modules that adhere to the design rules for VPort 704 modules. The modular design turns the VPort 704 into an extremely versatile communications interface, and makes the VPort 704 particularly well suited for use at field sites.
The VPort 704’s -40 to 75°C wide operating temperature, metal housing, passive backplane, and fanless design make it particularly well suited for harsh industrial environments and mission-critical applications, including oil and gas, trackside, and city traffic monitoring systems.
