RF/Video Switchers

General Description

The TL-EMS series RF switchers are fast and reliable tools for RF/video signal switching applications. They are designed as versatile reception, monitoring, signal distribution and signal testing applications in TV/FM/RF systems. They are controlled by a push button wireless remote control. Custom Switcher configurations and computer GUI control (via RS-232) are optional. The TL-EMS Series operating bandwidth is DC or 5 to 1000 MHz. Some models are suitable for RF only, whereas others have both RF and composite video switching capabilities.

TL-Rx-315 and Remote Control for TL-EMS Series

The TL-EMS series is controlled by push button wireless RF remote control, which consists of a general purpose radio frequency (RF) receiver (TL-Rx-315) and a compatible handheld 315 MHz RF transmitter.

The TL-EMS RF Switcher is connected to the RF receiver via serial control cable. The TL-Rx-315 receives control signals sent by the remote control, and then transfers them through the control cable to the Switcher. Multiple remote controls can be used in the same control zone provided each transmission is separated by a 2-second time gap.

  • The indoor wireless remote control range is up to 100 feet, through usual indoor building obstructions
  • Increase control distance up to 300 feet by optimizing receiver location using extended control cable
  • Unobstructed control range is up to 1000 feet

Note: RF signals do not pass through metal obstructions. Avoid placing the TL-Rx-315 near metal obstructions.

Switcher Models

TL-EMS-1x2 and TL-EMS-2x1 (DC to 1000 MHz bandwidth)

TL-EMS-2x1

The TL-EMS-1x2 allows users to direct one input signal to one of two outputs. This RF switcher is controlled by push button RF wireless remote with control range up to 100 feet through usual indoor building obstructions. Example: Basic signal control application – user can direct input signal to a desired branch of a two-way RF system, from a remote location.

TL-EMS-2x1 allows users to select between two input signals and transfer one signal to the output. This switcher is controlled by push button RF wireless remote with control range up to 100 feet, through usual indoor building obstructions. Example: Residential user can select between two broadband signals, e.g., two multi-channel antennas, from the TV room.

TL-EMS-2x4 (5-1000 MHz bandwidth)


TL-EMS-2x4

PDF Data Sheet

TL-EMS-2x4 is designed for signal distribution applications. It provides two (2) inputs and four (4) outputs. It allows a user to add four outlets to distribution system with two selectable inputs. Each output can select the desired input independent of the other three outputs. Each output will have either input 1 or 2 present. Example application: User can distribute full cable service to four outlets and also switch to local user’s content (e.g., security camera channels, HDTV antenna signal) on a second input. This RF switch is controlled by push button wireless remote.

Up to four TL-EMS-2x4s can be joined to one receiver to provide up to 16 outlets with two selectable inputs.
