3Auto Switching - Setup and Operation
Auto mode: Set the switch controller to Remote mode from its front panel
1) Log into the web interface on both amplifiers, and change
their control mode from LOCAL to REMOTE (note: the coaxial
switching only works when both amplifiers are in REMOTE mode). The
RF-CTRL-MODE setting is shown in Figure 2. When switched to
REMOTE mode, the amplifiers’ front panel RF On/Off buttons will be
inactive.
Figure 2
2) Connect all cables/wires as shown in Figure 1, and then turn
on the exciters, amplifiers, coaxial switch and switch controller.
If any power amplifier has a proper output power that is higher than a
pre-set minimum level, then the amplifier can be determined as
VALID. If both PAs are valid, then amplifier A will be selected as the
default PA (Note: The PA connected to REMOTE 1 on the back panel
of the switch controller is recognized the amplifier A, and the PA
connected to REMOTE 2 is recognized as amplifier B).
If there is a problem with the serial port communication between the
PAs and the controller, it will show error on STATUS->
LPTV_A_UART or LPTV_B_UART on the web page as shown in
figure 3.

Figure 3
Figure 4
The Coaxial Switch Controller’s web pages are shown in figures
3 and 4. AMP_FWD_MIN is the minimum output power that is user to
determine VALID amplifier and it can be use adjusted.
AMP_CHANGE_TIMES with the default setting of 3 means the total
number of times that the switch controller will try to switch back and forth
between two amplifiers using the coaxial switch before finally stopping.

RF Switch Controller User Manual
RF-SWITCH-USR-DOC-V2.0, 1/6/2017 Page 9 of 20
3) Switching Procedure: As shown in Figure 3, if the output power of
the amplifier A (now 47W) is less than the AMP_FWD_MIN (set to be
50W), then the Controller will check for a few more times to make sure the
output power is constantly lower than the threshold. This detection period
will take about 30 seconds. Once the power level is confirmed to be lower
than the threshold, then the Controller will switch from amplifier A to
amplifier B using the coaxial switch. The Switch over process is as follows:
first the Controller will mute both amplifiers remotely, then the Controller
will use the coaxial switch to switch amplifier B to the antenna and
amplifier A to the dummy load, as you can see the real time status showing
in LPTV_USED has changed from LPTV_A to CHANGE TO B in
FIG. 5, then the Controller will unmute amplifier B. Amplifier B will be
ramped up from zero to the rated power as shown in figure 6 and
7. Amplifier A RF remains off.

(Detected LPTV_A output is less than AMP_FWD_MIN, shut down both amplifiers,
and to switch to LPTV_B)

4) Likewise, when the output power of amplifier B is less than
AMP_FWD_MIN, the same steps as in step 3 are performed, shown in FIG. 8, 9 and
10.

4Manual Switching - Setup and Operation
Manual mode: Set the switch controller to LOCAL mode from its front
panel 1)Set the switch controller to LOCAL mode from its front panel then
the controller will change from auto to manual in STATUS-> MODE in
web page as shown in Figure 11.
Figure 11
(Change to manual mode)
2) The front panel T1 button stands for amplifier A and T2 stands
for amplifier B. Once the T2 button is pressed, the controller will turn off
both power amplifiers first and then control the coaxial switch to switch
to amplifier B and then bring amplifier B back to full power, as shown in
Figures 12 and 13.

And in LOCAL (manual) mode, even when the controller detects the
output power of the to-be-selected amplifier is lower than
AMP_FWD_MIN, it will still switch to that amplifier.

5Switching Operations - Summary
Please reference the steps below to perform typical switching operations. The Switch Controller
can be configured to operate in Remote (Auto switch) mode or Local (Manual switch) mode.
1. Auto Switch Operation: When the Controller front panel switch is set to Remote (Auto
Mode) –it will monitor the on-air TX output power and if this drops below a minimum
output power threshold (amp_fwd_min), the Switch Controller will automatically switch
over to put the standby TX on-air (TX On) and the on-air TX into the load (TX Off) . To
enable AUTO switching, the Switch Controller and both PAs all need to be configured for
Remote (Auto) mode. In Auto mode, the Switcher will always command one TX on into
the antenna and the other TX off into the load.
Auto Switch Action:
a. With TXA switched on and into the antenna and TXB switched off and into the
load, the Switch Controller will switch from TXA to TXB if TXA output power
drops below the minimum threshold (amp_fwd_min) –making TXA INVALID.
The Switch Controller monitors the output power of TXA, and if the output
power remains lower than the minimum threshold for roughly 30 seconds, then
the PA status will change to INVALID. The Auto switching process involves …
i. Switch Controller mutes both TXA and TXB (turns both PAs OFF –
monitored via LPTV_A_RF = Off and LPTV_B_RF = Off)
ii. Switch Controller switches coax relay so TXB is into the antenna and
TXA is into the load. This changes the status of the TX connected to the
antenna as monitored by LPTV_USED (it will change from LPTV_A to
CHANGE_TO_B).
iii. Switch Controller then unmutes TXB (turns PA B On) while maintaining
TXA off (leaves PAA off) –so LPTV_A_RF = Off and LPTV_B_RF =
Open (On).
iv. TXB ramps up from 0W to the rated output power, as may be monitored
by LPTV_B_FWD (power meter reading for TXB output power).
v. LPTV_USED changes from CHANGE_TO_B to LPTV_B).
b. Settings:
i. Switch Controller set to Remote mode (front panel switch).
ii. Both PAs RF-CTRL-MODE set to Remote mode (disables PA front
panel RF On/Off buttons).
iii. Both PAs output power is greater than min threshold (amp_fwd_min) –
i.e. both PAs are VALID.

RF Switch Controller User Manual
RF-SWITCH-USR-DOC-V2.0, 1/6/2017 Page 17 of 20
c. Notes:
i. Coaxial switching only works (in Auto or Manual modes) when both
amplifiers are in Remote mode. Setting PA to Local mode makes the PA
front panel TX On/Off button active for local manual control.
ii. If both amplifiers output power levels are below amp_fwd_min, and the
system is in Auto mode, then the Switch Controller will switch back and
forth between the two amplifiers until it hits the limit set by
amp_change_times.
iii. If both PAs are VALID, then amplifierA is selected as the default PA
into the antenna. The PA connected to REMOTE 1 on the back panel of
the switch controller is recognized as amplifierA, and the PA connected
to REMOTE 2 is recognized as amplifier B.
iv. If there is a problem with the serial port communication between the PAs
and the controller, it will show error on STATUS-> LPTV_A_UART or
LPTV_B_UART instead of Link_OK. Please note –the PA-to-
Switch_Controller connections must be made with the cables supplied
byAnywave.
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 PAweb 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 TXAon-air, turn TXB
PA Off via the TXB PAweb 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 TXAand 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

RF Switch Controller User Manual
RF-SWITCH-USR-DOC-V2.0, 1/6/2017 Page 18 of 20
the PA web interface) so that they do not communicate with the Switch
Controller and local on/off operation is restored to the PA front panel buttons.
3. Manual Switch (Local) –Switch Controller in Local (Manual Mode): This is the
normal Local (Manual) operating condition of the Switch Controller –with Switch
Controller in Local mode and the PAs in Remote mode. TXA is switched on and into the
antenna and TXB switched off and into the load. The user may manually (via the buttons
located on the front of the Switch Controller control which TX is on-air and which TX is
into the load.
Manual Switch Action: The Switch Controller has two front panel buttons, labeled
T1 and T2. When PAA is in Local mode, PA On/Off is controlled by the PA front panel
button. When PAA is in Remote mode, the PAOn/Off is controlled by the Switch
Controller T1 button. The same goes for PA B and the Switch Controller T2 button.
Local (Manual) switching between the two TXs is accomplished via the T1 and T2
buttons located on the front panel of the Switch Controller. Some rules apply. The Switch
Controller will only allow one PA to be turned on at a time (both TXs cannot be on at the
same time). For example, if both T1 and T2 are off (unlit), and T1 is pressed on (and lit
up) then TXA is ON and TXB will not turn on, even if the T2 button is then pressed (lit
up). If the user wishes to manually switch to put TXB on-air, then both T1 and T2 must
first be turned off (unlit), then the desired TX button may be selected –i.e. the user may
press the T2 button to switch TXB on and into the antenna.
a. The Manual switching process involves (switching from TXAto TXB) …
i. Both T1 and T2 buttons must be unlit (un-pressed) in order to switch to
the standby TXB
ii. Switch Controller T2 button is pressed (becomes lit)
iii. Switch Controller mutes both TXA and TXB (turns both PAs OFF –
monitored as LPTV_A_RF = Off and LPTV_B_RF = Off)
iv. Switch Controller switches coax relay so TXB is into the antenna and
TXA is into the load.
v. Switch Controller then unmutes TXB (turns PA B On) while maintaining
TXA off (leaves PAA off) –so LPTV_A_RF = Off and LPTV_B_RF =
Open (On).
vi. TXB ramps up from 0W to the rated output power of TXB, as may be
monitored by LPTV_B_FWD (power meter reading for TXB output
power).
b. Settings:
i. Switch Controller set to Local mode.

RF Switch Controller User Manual
RF-SWITCH-USR-DOC-V2.0, 1/6/2017 Page 19 of 20
ii. Both PAs RF-CTRL-MODE set to Remote mode (disables PA front
panel RF On/Off button).
iii. Both PAs output power is greater than min threshold (amp_fwd_min) –
i.e. both PAs are VALID.
c. Notes:
i. In Manual (Local) Mode, the Switch Controller does not monitor the PA
output power for a period of roughly 30 seconds to establish VALID or
INVALID –it simply switches instantly upon user command.
4. Both TXA and TXB Off at the same time: The Switch Controller will not allow both
PAs to be off (or on) at the same time. If this is desired for test purposes, then it can be
accomplished by an onsite engineer by disabling the PA-to-Switch Controller
communications and simply using the PA front panel On/Off buttons for individual PA
control. Simply follow the steps below.
a. Local (onsite): To turn both TXs off (or on) at the same time …
i. Put both PAs into Local mode by selecting Local on the PA web
interface (this transfers PA on/off control back to the PA front panel
button)
ii. Onsite engineer may then control individual PAOn/Off via the PA front
panel button.
b. Remote (via web interface): To turn both TXs off at the same time …
i. Because the Switch Controller always puts one PAon and into the
antenna and the other TX off and into the load, the only way to turn both
TXs off at the same time remotely is to turn the RF Off on both Exciters.
The Switch Controller will still command one of the two PAs on, but
without drive from the exciter, there will be no output power from either
PA. Be sure to remotely network to both PAs, both Exciters, and the
Switch Controller to have full remote control of the system.
