The engine is a multifunction controller and has been designed from the ground up with expansion and connectivity in mind.
Out of the box its default mode of operation is set to stand alone access control.
Once connected with UPAS, its configuration, settings and mode of operation can be changed, enabling the engine to perform many more tasks.
Stand Alone (Quick install, upgrade when ready)
Networked (OLED display & Comms Module)
Stand alone engines can easily be upgraded, simply by adding a in situ network upgrade.
A network upgrade consists of an upgrade key, an OLED display and a communications module.
When ordering a networked engine, or network upgrade, just select the required comms module.
WiFi (ESP8266) (ESP32 + Bluetooth)
Ethernet (W5500)
GSM (SIM800L)
LoRa (SX1278)
Many more modules in the pipeline.
The carriage is a sideways expansion board, upto seven can be chained together, in any order and any combination.
The engine has what we call IO train and analog train header connectors on its left hand side, these connectors are duplicated on each carriage.
Daisy chain carriages expand engine capabilites.
PLC Carriage (4 inputs & 4 relay outputs)
Video Switch (4 inputs & 4 video inputs, 1 video output)
Audio Switch (4 inputs & 4 audio inputs, 1 audio output)
Analogue Switch (4 inputs & 4 analog inputs)
Many more carriages in the pipeline.
