Comtrol Releases RocketLinx ES7110-VB PoE Switch for Security and Automation Applications

MINNEAPOLIS, Minnesota — February 23, 2012—Comtrol Corporation, a leading manufacturer of industrial device communication products, today announced the release of the RocketLinx ES7110‐VB industrial Power over Ethernet (PoE) switch. The unmanaged RocketLinx ES7110‐VB switch enables easy drop‐in PoE device connectivity in transportation, factory and industrial settings while the “VB” Voltage Boost technology provides the unique capability to power the switch from common 12‐ and 24‐volt supplies. With the RocketLinx ES7110‐VB, devices such as IP surveillance cameras, scanners, wireless access points and point‐of‐sale systems can be easily integrated within industrial settings without the use of separate 48V power supplies that are typically needed to power PoE systems. Eight PoE injector switch ports provide full IEEE 802.3af support, enabling connection of a wide range of PoE devices. Two Gigabit Ethernet uplink ports provide high bandwidth for data transmission to the larger network.

With a rugged heat‐dissipating housing and IP31‐rated industrial design, the ES7110‐VB assures reliable data transmission with support for QoS (quality of service), which ensures high quality video traffic transmission by adjusting the data transfer priority to guarantee throughput performance. Additionally, each Ethernet port has a Port Link Alarm, which can be configured to automatically trigger on connection issues; this warns administrators of abnormal operating conditions, ensuring quick resolution to network issues.

“The addition of the voltage boost technology to the RocketLinx ES7110 switch has allowed for expanded connectivity and power options,” says Rob Iten, Director of Marketing at Comtrol, “The ES7110‐VB is an excellent solution for transportation security, industrial applications, and IT environments where the easeof‐use and reliability of ‘drop‐in’ PoE connectivity is essential.”

Along with advanced PoE and networking capabilities, the ES7110‐VB is designed for reliable deployment in harsh conditions, with advanced features including redundant power inputs, port alarms, and an IP31‐rated industrial aluminum housing. The extended operating temperature range ensures consistent operation in places such as mass transit vehicles, factories, and outdoor settings.
