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 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).

Main Screens
The TReX top icon bar provides information about the display screen and operating
status. .The far right text indicates the selected main screen. This is either “IO” (inputs and
outputs), “TX” (transmit) or “RX” (receive).
The far left icon indicates system voltage as a proportion of the configured high and low
battery levels (MENU->INPUTS->BATT HIGH/LOW V).
The “X” icon is visible when no messages have been received for 2 minutes and on start-up.
The time in the middle is the current RTC time (MENU->SYSTEM->TIME).
The “S” letter indicates that the master or slave SCADA telemetry modes are in operation.
The “M” letter, when present indicates that a Modbus telemetry request packet has been
processed within the last 2 seconds.
The “Incoming” down arrow indicates that the TReX is receiving (absent when
RX is DISABLED). The “Outgoing” up arrow indicates that the TReX is
transmitting (if a transmitter enabled TReX).
The Icon “T” below indicates the TReX has been configured for telemetry stand-
alone “Back-to-Back Mirror Mode”.
The back to back arrows indicate the unit is operating in “Serial Link”
Telemetry mode.

TReX User Manual v2.14 Firmware
IO Screens
Screens that relate to inputs and outputs.
IO (1):
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 SCADA_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 SCADA_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.
SCADA_MASTER TReX units allow the “link count” to be viewed for all remote TReX
SCADA_SLAVE units.

TReX User Manual v2.14 Firmware
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 SCADA_SLAVE
TReX units (up to 10 SLAVE units) can be viewed by pressing the down button if the TReX is
configured to be a SCADA_MASTER.
