RF solutions TAURUS-8T1 Rugged Long Range Radio Transmitter

Operation

Press any of the switches to operate. The Transmitter will auto sleep between operations to save power. RF Transmit GREEN LED operates when Taurus is transmitting an RF signal. RF Acknowledge (if configured): GREEN LED will Flash at high speed to indicate that an acknowledgment has successfully been received back form the receiver. RED LED will Flash at high speed to indicate that an acknowledgment has not been received back form the receiver. Low Battery: If battery requires recharging Low Battery LED illuminates for 3 seconds after each operation. Recharging the Battery Recharge with either USB Cable or QI Wireless Charger

When Charging the Battery RED LED gives a slow Flash indicates charging is in prograess. When fully charged the GREEN LED is illuminated
Note:
If the Battery becomes very depleted it can take a few minutes before there is adequate charge to start the RED LED to flash!

Configuring Modes of Operation
To configure the modes of operation, unscrew the six enclosure fixing screws to access the internal circuit board. The SET switch is used to configure the operating modes.

The Following Modes can be configured using the SET Switch

1.  RF Mode of Transmission (FM or LORA Mode)
2.  Acknowledgment back from the Receiver
3.  Automatic Watchdog Transmissions
4.  Continuous or State Change Transmission

TAURUS Transmitters are factory Shipped with the following Settings

Restoring TAURUS to Factory Default

To Set the RF Transmission MODE
Possible options are FM, or LORA Modes 0 – 7. FM or LORA mode 0 provides the quickest response; from Transmitter SW pressed to Receiver Relay output. LORA mode 7 provides the longest operating range but with the longest time delay of from button press to receiver relay actuation.

Notes

1.  Range is dependant on many factors including the mode of transmission. Range can be reduced by 75% in built up areas with poor antenna, and environmental conditions.
2.  Battery life quoted is approximate based on 30 operations per day.
3.  918MHz devices do not have FSK mode.

To Set Continuous or State Change RF Transmissions

When a switch button is operated, TAURUS will transmit a “Button Down” RF Transmission. When a switch button is released, TAURUS will transmit a “Button Up” RF Transmission.

Continuous Transmit
TAURUS repeat transmits “button Down” in short bursts for as long as switch button is pressed. If the Acknowledgment is ON the receiver will reply after each RF transmission burst. This is ideally suited to momentary operation where the receiver output needs to be active as long as the user presses down a TAURUS Button.

State Change Transmit
TAURUS transmits an RF transmission only when the switch button is pressed or released (i.e. a state change). On each of these “state changes” TAURUS transmits up to 4 transmissions, or, “RF packets” (which can be seen by the GREEN LED flashing up to 4 times, If the Acknowledgment is ON the receiver will reply immediately. After receiving an Acknowledgment the TAURUS will cease sending any remaining of the 4 transmissions.

To Set Acknowledgement Request

Acknowledg ement Feature provides the user with LED indication that the receiver has successfully received the transmitters signal. When activated the TAURUS Transmitter includes an acknowledgement request within each radio transmission.
The response from the receiver is indicated on the transmitter via the RED / GREEN LEDs.

RF Acknowledgment from Receiver
Warning! When Acknowledgement is ON, TAURUS requests an RF signal back from the receiver. Whilst in theory if an RF signal can be transmitted one way then it can be returned, in practice occasionally the received acknowl-edgement many not penetrate as well as the Taurus transmitted signal.

To Set Watchdog Transmissions

If enabled, TAURUS automatically transmits a background “watchdog” RF Signal approx. every ~45 secs, RF Solutions Receivers with a Watchdog feature will hold a Relay contact “ENERGISED” as long as Watchdog is regularly received confirming the transmitter is in range and the system is operating correctly.When using Watchdog it may be useful to incorporate a Power Switch to avoid premature battery discharge., A power switch can be incorporated if this is required please contact our Sales Dept.
