ORDER CHANGE MASTER is used to switch out the MASTER unit of a network. It swaps the
roles of MASTER and SLAVE between the issuing SLAVE and the current MASTER. For further
information, see Paragraph 3.8.1.5.
3.4.5 Logging on to a Network
The TAP will always act as a MASTER. Therefore it will start a network at power-up and will
always succeed in the network logon. The TAP should be powered up before any TPTs are turned
on.
3.4.6 Status Indications
The TAP status and operation are indicated visually with a two-color LED on the side of the TAP
unit. Press and hold the LED button to view the status LED. See Table 3.4.6-1 for an explanation of
the status LED indications. If a TPT is logged on to the TAP, some indications also appear as sounds
and SynVoice messages in the TPT connected headset.
Note
The LED on the TAP is NOT NVG compatible.
3.4.6.1 Power-On BIT Failure
If any errors are encountered during the power-on BIT testing, the LED indicates MALFUNCTION.
