These are the only options available until the TPT is part of a TruLink network.
2.7.3.1 Starting a Network
When not located near the MASTER TAP or DPT, a group of TPTs can set up a standalone network.
The operator most likely to remain in the workgroup should start-up their TPT first, and set it to
MASTER. Only one TPT should be set to MASTER for a given channel. ALL other TPTs on a
given channel should be set to SLAVE (default setting).
An operator can only switch a TPT between SLAVE and MASTER before the unit logs on to a
network. If a unit is logged on to a network, the operator must cycle power to access the proper
change menu.
If the PTT button is not pressed within a few seconds of making a change, the new setting is aborted
and no changes are made.
To change to MASTER: Press the menu (M) button until “Slave” is announced. Press the toggle
button (*) until “Master” is announced then immediately press the enter button (PTT) to accept the
change.
If the TPT unit is set to MASTER, it will logon to the network (which is itself) automatically after a
few seconds or after the operator presses the enter button (PTT). The operator will hear a voice
announcement “Logon OK”.
2.7.3.2 Logging On to a Network
When logging on to an existing network, a TPT unit must be set to SLAVE.
A SLAVE will only announce, “Logon OK”, if it finds and logs on to a MASTER on the same
channel.
To logon to an existing network: turn ON the TPT, set it to SLAVE (if needed), set it to the proper
channel, and wait for it to automatically logon to the network. The operator will hear a voice
announcement “Logon OK”.
Note

To change a TPT to a SLAVE: Press the menu
(M) button until “Master” is announced. Press
the toggle button (*) until “Slave” is announced
then immediately press the enter button (PTT) to
accept the change.
If no network is available a “NEG RESPONSE” tone is heard, followed by a “NO SERVICE” tone
which is repeated until the next logon try.
