  • Remote-Controlled Dual Motor Remotely-Operated Boat

    Q-Boat 1800RP - Teledyne Marine Oceanscience

    ​The Oceanscience Q-Boat® 1800RP is designed to offer a reliable, high specification remotely-controlled platform for the deployment of popular acoustic Doppler current profilers from any of the major instrument manufacturers. Made of high-impact UV resistant ABS, the Q-Boat 1800RP features twin high power outdrives to give a 5 m/s (16 fps) top speed with the security of two engines. The flexible propulsion system allows the Q-Boat 1800RP to be equally effective at very low velocities (30 cm/s), providing a total solution to river discharge measurement. Ready for GPS and Oceanscience Hydrolink radio modems, the Q-Boat 1800RP is available with an optional extended range remote control system that allows control at over 750m distance.

  • Analog or Digital Communications Switching Systems with D Type Connectors

    RS Series - Cytec Corp.

    The RS Series computer controlled switching systems are designed to switch multi-wire groups of signal up to 25 wires. These systems are typically used for signals such as parallel TTL, RS232, RS422, WAN or modems, but can also be used for any group of analog or digital signals having a bandpass up to 30 MHz or a data rate up to 20 Mbps. A modular design concept is used that provides configuration flexibility by allowing display modules, different control modules and switch modules to be combined into a single chassis.LED displays and switch point status feedback are available on most systems. Computer control via IEEE488 (GPIB) and RS232 is standard, while TCP/IP Ethernet LAN, USB and manual controls are optionally available.

  • PCI-104 8-Port, 4-port, And 2-port Multi-Protocol RS-232, RS-422, RS-485 Serial Communication Boards

    104i-COM-8SM Family - Acces I/O Products, Inc.

    The 104i-COM-8SM (PCI-104) family of multi-port, multi-protocol (RS-232, RS-422, RS-485), serial communication boards deliver up to eight high-speed serial communication ports for use in a wide variety of applications. The boards were developed for use by system integrators and manufacturers in the design of industrial and commercial systems. Based on the XR17D158, the boards have eight enhanced 16550 UARTs, each with a set of modem signals (CTS, RTS, RI, DTR, DSR, CD) in RS-232 mode. Each UART has both a 64 byte transmit and a 64 byte receive FIFO. Ports are accessed via two 40-pin IDC type right angle header connectors. 2 and 4-port versions are available, as well as RS-232 only models.

  • Differential Pressure Level Transmitter

    HR3051-LT - HighReach Measuring & Controlling System Co.,Ltd

    t The diaphragm of at The Differential pressure Level Transmitter IS Used to Prevent at The Medium in at The Pipeline from Directly Entering at The pressure the Sensor the Component of at The Differential pressure Transmitter. It uses A filling Fluid SUCH AS Silicone Oil to The TRANSMIT pressure the BETWEEN at The Transmitter and at The Transmitter. At The HR3051-LT differential pressure level transmitter measures the level, density, pressure, and flow of liquids, gases, or vapors and converts them into 4-20mADC HART current signal outputs. The RP2001 can also communicate with the RST375 handheld terminal or the RSM100 Modem For parameter setting, process monitoring, and more.The measuring range of the HR3051-LT differential pressure level transmitter (when not moved) is 0-1kPa~2MPa, and the rated pressure of the liquid level flange is: 1.6/4MPa, 6.4MPa, 10MPa, 150psi, 300psi or 600psi.

  • Broadband Diagnostics

    TruVizion - ZCorum

    TruVizion gives you a comprehensive view into the health of your cable or DSL network, including up to 90 days of historical data.PreEqualization Analyzer lets you quickly find upstream impairments like reverse splitters, loose or corroded connectors and bad wiring. Plus, you can be proactive and actually fix those problems before they affect service for your subscribers.RF Inspector is an inexpensive app that can do what a meter can do, except it can do it on a tablet from wherever you happen to have Internet access. That means in the office, at home, or in the field.Upstream Analyzer shows you the RF signals for all ports and modems on your Cisco CMTS without any additional equipment, cabling or connectors, and yes, you can see ingress under the carrier with one click.

  • Proactive Downstream Spectrum Analysis

    SpectraVizion - ZCorum

    SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.
