TReX User Manual v15.30 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. The ‘D’ red LED remains lit if no IP configuration has been enabled.
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 Har ware Connection or Input Han ling 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).

All input and output states. Each IO highlighted state changes if the IO level is HIGH or
LOW. There is a small line above each input or output if HIGH, and a line below if LOW. All
ADCs (analog inputs) and DACs (analog outputs) show a bar graph as a proportion of full
scale and display a raw count from 0-1023. When scaling has been applied to an analog
output, the DAC value shown is the unscaled value.
In the middle, shown in larger text is “01”. The number“01” in this case is the telemetry UNIT
ID. When TELEMETRY->MODE is configured to MASTER a small down arrow may be
visible if the TELEMETRY->REMOTES have been configured to be more than 0. Pressing
the down arrow (when configured as a MASTER) allows the UNIT ID to be cycled to view the
IO of each remote slave in the system allowing a possible system of up to 88 digital IO, 22
ADCs and 22 DACs to be viewed.
Next to the UNIT ID is the smaller number “123”. Each TReX resets this number to the LINK
FAIL TIME each time a message is decoded. This “link count” reduces, and if reaches 0, the
link fail output can be operated.
MASTER TReX units allow the “link count” to be viewed for all remote TReX SLAVE units.

IO (2):
System voltage, current and internal operating temperature. RF is the temperature read directly
next to the RF power stage and will be higher than than the DIG board temperature while the
TReX is transmitting (not applicable for receiver only TReX units). Temperatures of the RF
power stage may reach 100 degrees Celsius under normal long term operation. These
temperatures are not the ambient temperature. The case of the TReX will NOT reach these
temperatures.
As with the previous IO screen, systems voltages and temperatures of all SLAVE TReX units
(up to 9 SLAVE units) can be viewed by pressing the down button if the TReX is configured to
be a MASTER.
IO (3):
This is the ALERT summary screen. This screen shows which alerting function is enabled and
active. There are many alerting functions possible such as link fail, RF fault, over temperature
and others. The screen shows through the bell icon in the top bar how many alerts have been
triggered since last cleared. The 3 digit count shows the total number of alerts raised for each
alert type. The large tick icon indicates that a particular alert is enabled. The bell icon for each
alert shows if there are new alerts that have been raised. See Alert Han ling for details on
alert configuration.
