PDF User ManualTL-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.
