2. Manual Switch (Remote) – Switch Controller in Remote (AUTO Mode): How does a

user manually switch the standby TX on-air remotely? The Switch Controller must be in

Remote (Auto) mode. Please see below for the proper steps to follow, step a or b,

depending on which TX is on-air. Step c highlights an alternative when TXB is on-air.

a. If TXA is on and into the antenna, and you wish to switch TXB on-air, turn TXA

PA Off via the TXA PA web interface. This will cause the Switch Controller to

switch to TXB.

b. If TXB is on and into the antenna, and you wish to switch TXA on-air, turn TXB

PA Off via the TXB PA web interface. This will cause the Switch Controller to

switch to TXA.

c. Also, If TXB is on and into the antenna, and you wish to switch TXA on-air, you

could alternatively turn TXA PA On via TXA PA web interface. This will cause

the Switch Controller to turn both TXs On for roughly 30 seconds before

switching to TXA and turning TXB off into the load. Note: Because TXA has

higher priority, this will not work the other way. If TXA is on-air and would wish

to switch to TXB, turning TXB On will not cause a switch to TXB, the Switch

Controller will turn both TXs on for roughly 30 seconds but will keep TXA

switched on-air and will turn TXB back off and into the load. Note: The Switch

Controller insures that one TX is on and one TX is off (after its 30 second period

of power monitoring). If you desire to turn both TXs Off at the same time, or

both TXs On at the same time, you will need to set both PAs to Local mode (via

LPTV_B_UART instead of Link_OK. Please note – the PA-to-

Switch_Controller connections must be made with the cables supplied

by Anywave.
