Universal rigid line bracket
RLA001-02: The universal bracket for 3-1/8", 4-1/16", and 6-1/8" rigid transmission line hangers provides an interface to adapt lightweight rigid hangers and vertical spring hangers to round horizontal tower members from 3/4" to 3" in diameter. This provides an off-the-shelf solution eliminating the need to have custom brackets fabricated prior to commencing installation.
Intraplex HD Link: This 950MHz STL was designed from the ground for today's data communications. Built around an integrated IP gateway, HD Link supports multiple channels of Intraplex-quality audio along with IP transport for HD Radio, and can take advantage of any available IP return path for TCP support with plug-and-play operation. The integrated IP channel for HD Radio program transport provides an ideal link from Importer-to-Exporter or Exporter-to-Exciter for both audio and data carriage, with a separate low-priority Ethernet port included for other LAN and control traffic. Advanced coding and error correction mechanisms provide resistance to bit errors that can cause glitches in HD Radio performance. Intraplex HD Link also offers powerful, reliable RF performance, high-quality multichannel audio performance, plus convenient set-up and reliable operation including full metering, monitoring, and command and control capabilities.
Model 730: Building on the Model 713, this TCP/IP-capable encoder is filled with new features. A front-panel knob allows virtually every setting to be viewed and modified from the front panel. This includes settings such as PI, PTY, DPS, IP, IP-Port numbers, AFs, time/date and RS-232 baud rate. The Model 730 also has built in dynamic DNS client service. This allows a static IP-name while being behind a dynamic IP address. Improvements in RAW command with FIFO buffer incorporate flexible free-format group redundancy. It supports DHCP and manual IP, either configurable from the knob/LCD. MAC address is visible from front panel LCD as well. It includes automatic RDS Group 4, clock time/date packets. When connected to the Internet, the internal clock is automatically updated. Easy time zone selection plus Daylight Saving Time scheduler can change the clock for up to 10 years. The Model 730 also includes scheduler capabilities to allow a planned scrolling PS message independent of an automation system. Allows events to be saved as either a one-time event (date/time, then expires) or a recurring event (M, T, W, Th, F/time, never repeats). Up to 99 events can be scheduled this way.
RF Scout XLT: The Dielectric RF Scout XLT monitors RF transmission system VSWR and forward power and is designed to aid in detecting VSWR problems as they develop. The system displays the values and can hold up to a year's worth of data and alarm events. In addition, the system can also be configured to monitor transmission line pressure and temperature. User settable options include warning and alarm levels, enable/disable interlock trip for each monitoring function and a VSWR alarm strike-out number. The unit's status is available via a 3" touch panel and through an Ethernet interface.
Active stereo matrix switcher
SS 4.4: The SS 4.4 provides matrix audio switching of four stereo inputs to four stereo outputs. Matrix switching allows any or all inputs to be assigned to any or all outputs. The SS 4.4 may be controlled via front panel switches, contact closures and/or the multi-drop RS-232 serial port. Additional features include stereo silence sensor with relay, front-panel stereo LED VU meters, stereo headphone jack with level control, powered monitor level control all with output selection switching, 16 GPIs, four GPO- open collectors and four SPST relays. Installation is simplified with pluggable Euroblock screw terminals. The SS 4.4 is supplied in a 1RU chassis.
