TReX User Manual v2.14 Firmware
Operation
Once a 13.8V source has been connected to the power connector the TReX start-up status is
displayed on the LCD.
When the TReX is operating normally, the two green status LEDs flash briefly once every
second.
When decoding messages, the “A” green LED is held on for approximately one second.
The “C” red LED is held on for the duration of a transmission, while processing TCP data,
Modbus protocol commands and decoding received messages. Both the “C” and ‘D’ red LEDs
light while starting.
On start-up under normal operation there is a message sent out the serial port. The message
indicates the firmware revision, serial number other software related information.
After finishing the start-up procedure and loading of configuration settings the TReX enters its
receive and decode mode of operation. The TReX now waits for commands to be entered
serially for processing or inputs to be triggered. These may be either protocol messages to be
processed or commands related to the configuration of the device. Serial messages may arrive
on any serial port, or may also arrive through a TCP connection.
When messages are received and decoded, they are immediately sent out the serial port in the
format of the configured protocol in use.
Messages are transmitted as per the input configuration when inputs change state. Please refer
to Input Output Hardware Connection or Input Handling sections on this manual for
further information.
The TReX outputs are driven high or low, or for a particular period of time depending on
configuration. The outputs are controlled via the WTE Output Control Protocol message
received and decoded. Each output can be configured to operate under various error states
(Refer to Outputs).
