Switches



624B
Video Sensor

Monroe Electronics’ Model 624B Video Sensor provides automatic 2x1 balanced stereo-audio-follow-video switching, controlled by Video sync pulses.

The 624B detection circuit monitors the loss of composite sync pulses on the primary video input. It automatically switches to the secondary video input upon loss of sync pulses. It remains in this state until the primary video returns, prompting the 624B to switch back to the primary video input.

This state of the art configuration allows accurate, clean, dependable switching in unattended locations.

625A
RF/IF Sensor

Monroe Electronics’ Model 625A RF/IF Sensor provides automatic 2x1 RF/IF switching controlled by the loss of video modulated RF carrier.

The 625A’s sense input circuit monitors horizontal sync pulses on the video modulated RF carrier and automatically switches to the secondary input upon a decrease or loss. The relay remains in this with the secondary input connected to the output, until the sync pulses on the video modulated RF carrier return. This causes the primary input to switch back to the output connection.

The 625A’s sensing input requires an external bandpass filter and pad for multiple channel feed conditions.

627A
A/V Switch

Monroe Electronics’ 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 Monroe Electronics program timers, remote controls or CATV Cue Tone receivers.

628
Encoder Sensor

Monroe Electronics’ Model 628 Encoder Sensor automatically switches in an alternate program feed whenever you stop
scrambling!

The 628’s Sensor input samples scrambled baseband video for sync suppression, such as from a Jerrold MVP-II Encoder.

When the sensor circuit detects sync suppression it causes the 628’s secondary input to be connected to the common output. It will remain in this state until sync suppression stops, which causes the 628’s primary input to be connected to the common output.

R164
Stereo A/V Switch

Monroe Model R164 Stereo Audio/Video Switch module provides 2x1 (AB) balanced stereo audio follow video or  IF/RF switching.

The 2x1 switch will respond to a contact closure, 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 R-164 can be controlled by Monroe Electronics’ program timers, remote controls or CATV Cue Tone receivers.

R165A
Stereo A/V and IF/RF Relay Panel

Monroe Electronics’ Model R-165A Audio/Video Relay Panel provides four, independent 2 x 1 (A/B) balanced stereo audio follow video relay switches. The switches are controlled by Monroe Electronics’ 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.

R184
16x1 Matrix | Relay Panel

The Model R-184 16x1 Relay Panel, is designed to allow remote switching of signals, via PC based software. Signals may be any RF type, from 5 to 1000 MHz. The R184’s switching allows the user to route various remote signals to a single location, for use in testing or status monitoring.

Control is via an RS485 connection. This may be from a computer, or via an ethernet connection through a suitable adaptor. PC control software included.

R192
Multi Channel Backup Switch

Each of the R192’s ten (10) individual detection circuits monitor the loss of composite sync pulses on the primary video input. They will automatically switch to the secondary video input upon loss of sync pulses. It will remain in this state until the primary video returns, causing the section to switch back to the primary video input.

When a switch section loses primary video and switches to the secondary, the red led panel indicator, for that sensor on the front of the R192, lights up.

R232 MultiPort RF Routing System R232
MultiPort RF Routing System

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 Monroe 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.
