5.3 TM E NGINEERING (TM ET O NLY )
‘TM Engineering’ is accessed by clicking on the ‘Eng’ button on the TM Status panel. The settings
accessed in the following pages are stored in the TM, some being sent to the NI for configuration
purposes as part of the Solar supervisory system, others are sent for information purposes only.
The ‘TM Engineering’ window also has an ‘Eng’ button that must be selected (IN) before a change
can be made, whereupon the ‘Apply’ button will become active. Changes in settings will not
become active until the ‘Apply’ button is selected. The ‘TM Engineering’ window is closed by
selecting the ‘Close’ button or by using the close icon 

 in the top right hand corner. Any changes
made but not applied will be lost when the window is closed.
Also visible on the ‘TM Engineering’ window is an ‘Ack Alarms’ button, which will be unavailable
(greyed out). See Section 12 – Alarms for full details of this function.
5.3.1 Sync Timing
The purpose of ‘Sync Timing’ is to facilitate setting the size of the Solar packet buffers that are
crucial to the correct operation of a Solar simulcast radio network. Due to the detailed nature of
the subject, the information is presented in full detail in Section 7 – Solar (Sync) Timing of this
manual. The user is well advised to study this section carefully prior to system optimisation.
At the initial commissioning stage “nominal” values will be used to get the system operating.
