TAURUS-8T4 Transmitter Remote Control Base Module
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
progress.
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
- RF Mode of Transmission (FM or LORA Mode)
- Acknowledgment back from the Receiver
- Automatic Watchdog Transmissions
- Continuous or State Change Transmission
TAURUS Transmitters are factory Shipped with the following Settings
| RF Transmission | FM |
|---|---|
| Acknowledgment | OFF |
| Watchdog | OFF |
| Transmission Type | Continuous |
Restoring TAURUS to Factory Default
To Set the RF Transmission MODE
This sets the type of RF Transmission.
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
- 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.
- Battery life quoted is approximate based on 30 operations per day.

LoRa Mode 6| 7| 640 mS| 18K
LoRa Mode 7| 8| 1.28 Secs| ~9,000
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
Acknowledgement 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 acknowledgement 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
