One major US broadcast television network used Comtrol’s RocketPort SMPTE products during recent large-scale studio upgrades to connect to various production system components. The RocketPort cards provided the needed expansion of serial ports in the news studio to connect the following devices to the control system:
- Video Server – computer that stores and queues programs for playback
- Master Control Video Switcher – system that allows interchange between all video sources
- Back-up Automation Control Switcher – standby system that is always up and ready to take over in the case of a failure
- Graphic Insert Card – device that allows on-screen graphics to be shown
- Parental Rating Injector – device that inserts the rating of a TV program
- Commercial Ad Switcher – system that allows ads to be played
- Automation Control Switcher – system that automates the broadcast and commercial process
Comtrol’s RocketPort SMPTE 8-Port uPCI controller card and the RocketPort 8-Port interface (or rack mount interface) were deployed in 28 studio locations across the US over the span of a year. The RocketPort SMPTE products are designed specifically for the broadcast industry, are available in 2-port and 8-port densities, and support RS-422 serial communications at speeds up to 921 Kbps.

Laser scanners are very well suited for providing additional levels of security in areas that are deemed critical such as, chemical facilities, food processing facilities, water treatment facilities, nuclear power plants, and power substations.
Scanners can be deployed in areas where complete protection against unauthorized access or entry is required.
Laser scanners are also commonly used in other security, transportation and industrial applications such as:
- Intrusion detection
- Perimeter/Façade Security
- Theft deterrence/retail
- Access control
- Camera tracking/profiling
- Vehicle classification
- Open-road tolling
- Container port automation
- Vehicle separation in toll booths
Laser scanners function according to the principle of the pulse time-of-flight measurement. An invisible laser beam pulse is emitted in a fan shape with a high angular velocity as a measurement probe. If this hits an object, it is reflected and this is registered in the laser scanner’s receiver. The time take for the pulse to be sent and received again (light time-of-flight) is directly proportional to the distance between scanner and object. The exact position of the object is calculated from the sequence of pulses received. Violations of the monitoring areas are reported immediately through an output signal switching device.

UL294 is the standard of safety for Access Control System units that all access control systems must meet. UL294B is a newer standard, specifically for the use of Power over Ethernet (PoE) components used within access control systems where PoE is the primary power source.
Government and state regulations are moving toward required UL294 compliance. Comtrol’s RocketLinx ACS7106 is the first UL294B certified switch enabling confidence in deployment and integration within access control systems.
The ACS7106 switch features four 10/100BASE-TX PoE Plus ports for providing power and data to remote PDs (Powered Devices) such as access card readers and IP surveillance cameras, and two 10/100/1000BASE-TX uplink ports that assure maximum throughput for high bandwidth applications.
The official site for the UL Standards states that:
1.1 These requirements apply to the construction, performance, and operation of systems intended to regulate or control:
a) Entry into a protected area or a restricted area or
b) Access to or the use of a device(s) by electrical, electronic or mechanical means.
Comtrol’s DeviceMaster RTS family of serial device servers enables browser-based remote port/device monitoring and configuration and provides an application software platform for local processing. It is designed for device networking versatility and offers software-selectable ports (RS-232/422/485) as well as the ability to host local embedded programs that are commonly used for intermediate serial data processing, protocol conversion, and other data-based applications.
Ranging from 1-port models that provide single-device networking to 32-port models that offer high-density connections for specialized applications, the DeviceMaster RTS product is a network-attached solid-state embedded device server network serial port that delivers exceptional price, performance and reliability.

Comtrol Releases ES7206-XT Gigabit Extended Temperature PoE Switch
MINNEAPOLIS, Minnesota — February 4, 2014—Comtrol Corporation, a leading manufacturer of industrial device connectivity products, announced the release of the RocketLinx ES7206-XT Power over Ethernet switch. Comtrol’s unmanaged ES7206-XT contains four Gigabit IEEE 802.3af/at PoE ports, one Gigabit copper uplink port, and one Gigabit SFP uplink port supporting multi-mode or single-mode fiber connections. Featuring Voltage Boost technology, the ES7206-XT enables direct 12-36 VDC input supporting vehicle, building, and factory power systems while delivering reliable power to PoE devices.
“Comtrol’s new Gigabit PoE Plus Ethernet switch is designed for outdoor PoE applications with its extended operating temperature range. Its ruggedized features make the RocketLinx ES7206-XT an ideal solution for IP surveillance, transportation, mining, and other demanding PoE applications,” says Bradford Beale, President of Comtrol, “Additionally, the Voltage Boost feature and ‘plug-n-play’ installation make it easy for security and traffic integrators to deploy.”
As an unmanaged switch, the ES7206-XT is designed for quick, convenient setup while advanced capabilities and NEMA TS2 certification for traffic applications enable the switch to provide reliable PoE connectivity under extreme conditions. The Gigabit copper and fiber uplink ports allow connectivity for the connected high power, high bandwidth PoE devices such as access points and HD pan/tilt/zoom cameras. Redundant power inputs, polarity and over-current protection, and a configurable alarm relay round out the safety features that make the Comtrol RocketLinx ES7206-XT the optimal solution for your next PoE application.

The intelligence for monitoring all functions that take place within each substation is housed in a small building. One system integrator has been incorporating Comtrol’s RocketPort card within its substation management software for five years.
The RocketPort card is installed into the rack mount rugged computer, where the ports are
connected to relays, RTUs and other intelligent electrical devices (IEDs) for data collection and control. Each device within a substation sends information serially to the RocketPort, which the substation computer then communicates to the central station by Ethernet across the WAN (Wide Area Network).
Comtrol’s RocketPort card provides a reliable bridge between all the functions happening at the substation to the central station. This allows for closer monitoring, and to ensuring that everything is working properly and providing power to the appropriate end-users.
