Responses are all transmitted using the default settings for modulation type and protocol. The

payload is also sent directly out the serial port and TCP sockets for when acknowledgement is

required via IP.

Typical Operation

The base-station TReX sends single messages, or many batched together as required.

The transmitter can send an auto incremented ticket ID, or the ticket ID can be manually

selected as part of the Acknowledge and Confirm Protocol.

Using WT Protocol allows the use of the Variable Content Macro **01 to be used to transmit

with an automatically incrementing ticket ID.

Receiving TReX units can acknowledge multiple messages if messages have been received in

a batch.

e.g. The remote TReX unit receives 3 messages all to be acknowledged (ticket IDs 345, 346

and 347). The following is transmitted.

ACK[345,346,347]

Upon reception of any message requiring confirmation, the TReX shifts from any screen

currently on, and does not allow leaving of the confirmation message screen until the message

has either been accepted or rejected. Any messages received while waiting for confirmation

will be logged and can be inspected at a later time.

Example 1:

Message payload to have delivery acknowledged is transmitted.

Message Payload:

Bob, go to Pukeko Place urgently.-[345-1]<CR>

Remote TReX responds with:

ACK[345]
