Page 28: Radio Link Encryption
Radio Links The TReX can be configured to use industry leading AES 256-bit, block chained encryption for all used radio data links. This means messaging between WTE TReX radios cannot be intercepted without sharing of a key between devices. A unique, non repeating timestamp is transmitted with every packet, ensuring that same content messages are not repeated, and also allows for protection against replay attacks.
Page 29: Dmr Messaging
All protocols implemented support direct DMR messaging. In order for a protocol to transmit directly to a DMR radio the DMR_DB database should be configured with group IDs, together with colour code, radio type and DMR radio frequency.

Page 30: Programmable Logic Controller
TReX User Manual v15.30 Firmware Programmable Logic Controller An optional feature of the TReX-460 is a telemetry-optimised PLC. This allows automated control of outputs and transmissions based on configurable inputs, serial input, received messages, counters, comparators and timers. This PLC utility uses a ladder logic programming similar to other commercially available PLC devices.
Page 31: Two-Way Paging
Accepting the job can be performed with a simple keypress that will send receipt to the dispatch system that the vehicle is on-route. See WTE Ack and Confirm Protocol for usage details. With a single keypress, key messages can be responded to. Details of the responder are returned and logged.

Page 142: Protocols
WT Protocol The WT Protocol is the default protocol used by WTE products. It allows for a variety of over the air transport methods (such as POCSAG and DMR paging) to be used and a variety of baud rates.
Page 143 = 4800 4 Level GFSK NOTE: Although the protocol supports the following modulation types and channel spacings, the supplied WTE product may only support a subset of these modulation rates (determined by regional restrictions). <SPACE> is a single space character.
Page 144: Serial Only Output
All messages received come out via the serial port as configured in by the *RX_PROTO setting: If *RX_PROTO=WTE then the output will look like: WT1234567A10<SPACE>TEST<CR> The exact same format allows units to be connected together, or protocols to be converted from one type to another.
Page 145: Level Modulations
4 Level Modulations All WTE 4L modulations, regardless of the used channel spacing, transmit data using the WTE_EN transport method. 4L modulations also do not include forward error correction information as all 2L modulation supported do. This gives much faster possible transmission speeds.

The intended behaviour is that the TReX will turn on the cooling fan for 10 minutes whenever it’s onboard temperature sensor passes 90°C.
Page 188 TReX User Manual v15.30 Firmware This PLC program takes advantage of the Alert Output functionality of the TReX-460 to provide an intelligent response to alert events. This is achieved by using the configured alert output (Output 8) as an input to the PLC program.

TReX User Manual v15.30 Firmware Simple Multi Unit Alarm System In this example, one TReX-460 is configured as a SCADA Master Device and two TReX- 460s are configured as SCADA Slave Devices. The Master Device has two LED indicators connected to Output 1 and Output 2, while both slave devices have smoke sensors connected to Input 6.

The WTE PLC Configuration Tool is a desktop application designed to enable fast development of TReX PLC programs. This tool is available free of charge. The WTE PLC Configuration tool gives the ability to not only construct TReX PLC programs, but to also run and debug these programs in a simulated TReX environment.

Page 241: Secure Nationwide Paging
Secure Nationwide Paging In order to transmit secure messages across an existing nationwide paging service (to be decoded by a TReX-460) the message must be encrypted by another TReX, and the encrypted message then provided to a nationwide paging service provider.
Page 242 TReX User Manual v15.30 Firmware The message will be decrypted, and displayed on the RX screen. If the selected output protocol is WTE, then the decoded message will also be returned out the serial port. This method allows secure activation of TReX outputs or reception of sensitive information for processing or retransmission.
