The ST-1 as a PTL Remote
Your PTL Remote is normally set to pair to the Master PTL on startup, or see ‘Switching ON and PAIRING the Remote’.
Status screen
The top line shows date and time, if this count is active your device is paired.
The second line shows how many units are connected. i.e. 2 Unit(s).
The third line shows the Mode the PTL is operating, i.e. SHUTTLE MODE.
The fourth line shows the remaining time for the phase.
THE MAIN SCREEN
The Main screen will display the lights for the Master on the left and the Slave on the right.
If in Gating mode only one PTL will be visible.
The battery level is shown above each light.
An Alarm will indicate if the battery reaches a ‘too low’ level and recharging is required.
Tap the Red lamp to change to Red if the light is on Green.
When BOTH lights are Red, you can tap either Green to change that light to Green.
Switching ON and PAIRING the Remote
A Start-up page and sequence is displayed when the ST-1 is turned ON, this is done by pressing and holding the lower-right side button.
After the Startup sequence, press the button to start the Local Connect App.

SHUTTLE MODE
A demand for Green or Red signal on the Master or Slave is entered on the Remote Control unit. For Shuttle Control, on startup, both the Master and Slave will rest on Red until a demand for Green is entered.
To enter a demand for either Red or Green, tap the STOP or GO buttons on the Remote Control. The DEMAND indicator is activated indicating a demand for either the Master or Slave.
You can directly select the GREEN for the opposite light: the lights will sequence through to the ALL RED sequence and then to the selected GREEN.
LIGHT CHANGE SEQUENCE EXAMPLE
Master Green Both Red Slave Green
REAR BEACON LAMP
The Beacon Lamps mounted behind the Traffic Lights flash on each unit when the Red Lights are ON. This is useful for the operator to know the Lamp is on RED phase when behind the actual lights. It also acts as a Caution indicator for Vehicles.
PLANT CROSSING (OR COPY MODE)
Plant-Crossing scenario is used to enable both directions of traffic flow along a roadway to be simultaneously stopped, e.g. to allow road construction vehicles (or pedestrians in a controlled environment) to cross.
On start-up, the Master is Red and the Slave copies this and is also RED.
The operator can enter a demand for Red signal using either STOP buttons on the Remote. Both the Master and Slave units will then cycle to Yellow and the Red signal phase.
To change back to Green signal, tap either the Master: GO or Slave: GO buttons.
Plant Crossing Control example:
- Both the Master and Slave are on Green.
- Tap either the Master: STOP or Slave: STOP buttons
- To resume traffic flow, tap either GO button.
To change the settings, tap the 
button at the bottom of the screen then tap on the Settings Menu button:
- Logging Enabled – enables logging to diagnose issues
- Auto Connect – will automatically connect with the last connected device
- Startup Tab – on startup; the app will jump to this tab directly and will start scanning.
- Clear Auto–Connect Serial Nos – will clear the list of last connected device serial numbers
- Clear Cache – will clear any locally cached data
