DTMF Decoder - 637

637-DAS.png

The Model 637 Dual Tone Decoder is a microprocessor controlled DTMF® decoder. The 637 is capable of accepting a sequence of from one to four DTMF signals, and responds by actuating its integral DPDT output relay. The relay action may be momentary, latching or toggling. Programming the code sequence is accomplished by digital rotary switches along the front edge of th PC board. Please refer to the instruction manual for the 3185E for specific switch and control settings.

A/V Switch - 627A

627A-DAS.jpg

The Model 627A Stereo Audio/Video Switch module provides 2x1 (AB) balanced stereo audio follow video switching. The 2x1 switch will respond to a contact closure or a transistor switch to ground or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device. The 627A can be controlled by Digital Alert Systems program timers, remote controls or CATV Cue Tone receivers.

Stereo A/V and IF/RF Relay Panel - R165A

The Model R165A Audio/Video Relay Panel provides four, independent 2 x 1 (A/B) balanced stereo audio follow video relay switches. The switches are controlled by Digital Alert Systems’ program timers, remote controls or CATV Cue Tone® receivers via contact closures or logic inputs. Each video relay will also function as a high quality IF/RF 2 X 1 (A/B) switch, with frequency response to 950 MHz. Auxiliary relays 1 & 2 available for GPI or SAP switching.

Audio/Video Switch - R197AV

Local/Network Controlled Independent 4-channel Stereo Audio or Stereo-Audio-Follow-Video/RF Switching System.

MultiPort RF Routing System - R232

The R232 starts off with a multiple-input – multiple-output switching matrix featuring dual independent A & B outputs that can select any of the 32 inputs. Since the R232 uses two matrixes, the outputs are non-blocking, so each output is completely independent of the other and can share the same input or any other input. This makes the R232 truly unique for test monitoring as different instruments or monitors can be configured on each output and then look at the same or any other input. Never before has it been this easy to monitor one port and compare it with another port using the same or different test heads. Speed up testing and perform more thorough examination in much less time and with much less equipment. Adding to the suite of R232 features is the 20db of gain from input to output, which is able to pull signals up to valid testing levels without introducing performance errors over the operating band, and to minimize noise it shunts unused inputs and outputs directly in to 75Ω The future of Hybrid Fiber Coax plants requires using even greater bandwidth on the coax side. Services like DOCSIS 3.1 and many others requires ever increasing bandwidth and the R232 is up to the task, operating up to 2GHz – well beyond even the most current standards. Port selection is accomplished via a 10/100 Ethernet control port using a simple browser interface or the exclusive CrossPoint Control Protocol (MXCP™) making interfacing with automation and test equipment substantially easier over less sophisticated or manual controls. The R232 features the unique side-attached Pocket Power Supply™ to create the densest, most compact 1RU chassis design without resorting to external power blocks and boasts top-notch performance from 5MHz to over 2GHz with 20db of gain making it perfect for large-scale test port management.
