1 Product Appearance
1.1 Front Panel
LED_PWR
The green light will be on when the DC voltage of the internal power supply is within the normal
range (48 VDC ~ 52 VDC).
The green light will flash when the DC voltage of the internal power supply is out of the normal
range (48 VDC ~ 52 VDC).
The green light will be off when the external power supply is turned off, or the internal power
supply module does not work.
LED_RS485
The green light will stay on or flash when internal communication is normal.
The green light will stay constantly off when internal communication is abnormal.
LED_FWD
The blue light will be on when RF_OUT has power output.
The blue light will be off when the RF button is turned off, or the PA enters the auto-protection
mode and therefore shuts down its RF output. There are several situations which will result in
auto-protection mode, such as the input power is too high, the reflected power is too high, or the
temperature is too high.
LED_ALARM
The red light will be off if there is no alarm.
The red light will be on if there is an alarm.

1.2 Back Panel
RF IN-A/RF IN-B
Connector: N
Impedance: 50 Ω
Note: If input power from RF_IN is lower than the rated input value, the output power will be
lower than the rated output power accordingly. This is because the PA has a fixed gain. If the
input level from RF_IN is higher than the rated value, it will result in RF output distortion and
performance deterioration. If the output power is higher than the preset FWD threshold, it may
trigger the current-limiting function. The PA will enter the auto-protection mode, and there will
be reduced RF output or even no RF output.
RF_OUT
Connector: N
Impedance: 50 Ω
Note: RF_OUT must be connected with a load with proper impedance, otherwise the PA will
enter the auto-protection mode and there will be in no or reduced RF output.
RFMON (reserved)
ERS485-A
Connector: DB9-M
Note: Connected to the REMOTE (RS232) port of exciterA (with an
RS232-to-485 adapter), which is used for control and
communication between the PA and the exciterA.
ERS485-B
Connector: DB9-M
Note: Connected to REMOTE (RS232) port of exciter B (with an
RS232-to-485 adapter), which is used for control and
communication between the PA and the exciter B.

Note:
1) FWD_POW/REFL-POW/REJT-POW are respectively the forward power, reflected power and
rejected power meters of the amplifier. VSWR value is calculated accordingly based on these
power meters. If any of these meters has exceeded the pre-set thresholds which can be set in the
System Set Tap->ALARM-PARA section, then it triggers an alarm accordingly, and the amplifier

PA-U2D-C-FA User Manual
ACT-PA-U2D-USR-DOC-V2.2, 09/25/2019 Page 10 of 20
will enter into the auto-protection mode and run at reduced power levels, or even no TX output.
2) ATT stands for the internal attenuator setting. It is normal to see ATT decrease from its maximum
value (127) to its pre-set value (set in System Set Tap) slowly during a reboot. ATT is also used in
AGC mode when theAGC target value is away from the free-run level.
Important: If there is an alarm that triggers the amplifier to go into the auto-protection mode,
then the ATT’s value will increase and the amplifier will run at reduced power to protect it from
potential damage. This kind of power drop is by designed for protection purpose. So, if you notice
the output power drops, please first to check if there is an alarm in the system and if the current
ATT value (in the Status Tap) matches what is set in the System Set Tap. Don’t increase the input
of the PA (or the output of the exciter) without checking alarm(s) and ATT value/setting first.
Otherwise, once the alarm has been cleared, you may have a much higher input level than needed,
and it may damage the amplifier and may void the warranty.
3) AMP-TEMP is the internal temperature readings measured by an onboard temperature sensor. If
this value is higher than the pre-set threshold (TEMP-MAX in the System Set
tap->ALARM-PARA section), then it triggers an AMP-TEMP alarm, and the amplifier will enter
into the auto-protection mode and run at reduced power levels, or even no TX output.
4) 50V-CUR1 is the main transistor current readings. If this value is higher than the pre-set threshold
(50VCUR-MAX in the System Set tap->ALARM-PARA section), then it triggers a 50V-CUR
alarm, and the amplifier will enter into the auto-protection mode and run at reduced power levels,
or even no TX output.
5) EXCITER shows which exciter is currently selected and on air. Each PA can connect with up to
two exciters (ExciterA and/or Exciter B) as needed.
6) FREQ is the current channel frequency read from the exciter. If the internal communication
between the exciter and the PA is lost (via RS485), or the PA is not connected with an Anywave
exciter, then this parameter may not reflect the actual channel information.

PA-U2D-C-FA User Manual
ACT-PA-U2D-USR-DOC-V2.2, 09/25/2019 Page 11 of 20
Note:
1) FWD-ADJ/REF-ADJ/REJT-ADJ: These are used to calibrate the forward power, reflected power
and rejected power meters. Calibration values may vary by channels. Every amplifier is calibrated
at the channel specified by order in the factory before shipment. If you would like to run the
amplifier at a different channel (within the allowed range of the amplifier) or to calibrate the
readings again for any reason, please contact the manufacturer for technical support. Otherwise,
inaccurate readings caused by the wrong calibration may cause false alarms (if readings are higher
than the actual power level), or lose the ability to protect the amplifier (if readings are lower than
the actual power level) and may cause damage to the amplifier and void the warranty.
2) ATT: This is to set the value of the internal attenuator in the amplifier. The higher the value, the
more it attenuates the input level and therefore the output level. If the default “0” stands for no
attenuation at all, “4” stands for 1dB in attenuation, “8” stands for 2dB in attenuation, and so on.
We recommend keeping the value as default (0). Usually, the ATT value in the Status should
match the ATT setting in System Set Tap when the amplifier is running normally. If not, it is
possible that the amplifier has triggered some alarm and entered the auto-protection mode.
3) RF-RESTART: if an amplifier is in the auto-protection mode, you can set RF-RESTART to ON to
clear all the alarm(s) and restart the amplifier. After RF-RESTART, please check again to see if the
alarm is gone and ATT is back to pre-set value. Sometimes you may need to clear more than once
to bring the amplifier back.
Important: To be safe, before you run RF-RESTART to clear the alarm, please first lower the

PA-U2D-C-FA User Manual
ACT-PA-U2D-USR-DOC-V2.2, 09/25/2019 Page 12 of 20
exciter’s output 10dB down than its original settings, or set the exciter’s output to -20dBm, or set
the ATT to 60, to avoid over-drive the amplifier after it recovers from the auto-protection mode.
Once alarms are cleared, you can slowly increase the exciter’s drive or lower the ATT value to
bring the amplifier back to the original level.
4) RF-SWITCH: It is to turn the TX of the amplifier ON or OFF.
5) AGC: This is the switch to turn ON/OFF AGC function and FWD-STARDARD is to set the target
AGC value.
6) GRID-VOLT: It is highly NOT recommended to change any setting in GRID-VOLT without the
permission of the manufacturer. Unauthorized changes in GRID-VLOT may cause damage to the
amplifier and void the warranty.
7) ALARM-PARA: This section is to set the threshold for all alarms including forward power alarm,
reflected power alarm, rejected power alarm, VSWR alarm, high current alarm, and
high-temperature alarm. We recommend keeping those settings unchanged because they are
pre-set and optimized for the application before leaving the factory. If they are changed without
the permission of the manufacturer, it may leave the amplifier in insufficient protection and may
cause damage to the amplifier and void the warranty.
8) PARA-RESET: This is to restore all parameters back to default/uncalibrated settings. Every
amplifier’s parameters have been calibrated and optimized for its application. Please do not run
PARA-RESET unless it is suggested by the manufacturer.
9) REMOTE-UPDATE: This is to upgrade the firmware of the amplifier. Please only upgrade the
amplifier with the permission or guidance from the manufacturer. Turning the amplifier into
upgrade mode will make it stop working immediately, and it loses its web pages access too. If the
amplifier is turned into the upgrade mode by mistake, the only way to bring it back is to power
cycle the amplifier.
Note:
1) This section is to set the network configuration of the amplifiers. It allows users to set the IP, mask,
and gateway of the amplifier.
2) If a user cannot recall the IP and therefore cannot log in remotely after making a change, he can
either reset the IP back to default (192.168.1.210) from its front panel RESET button by pressing
it for 8 seconds or longer, or he can check the IP from the front panel touch screen. Please note:
both recover methods have to be done locally.

Block Diagram: Press the “Exc A/B” graphic to navigate to the Dual Exciters Switching screen
(shown below). This screen shows which exciter is currently on-air (highlighted in GREEN) and
allows the user to manually change the on-air exciter.
3.2.2. A/B Exciter Icon Screen
Dual Exciters - Switching Screen: Pressing the “Exc A/B” icon will bring you to the Dual Exciters
Switching Screen, a shown below.
Manual Exciter Switchover: As shown above, Exciter A’s status is in “GREEN”, indicating that Exciter A
is the current on-air exciter, while Exciter B is standby. Pressing the “Exciter A” or “Exciter B” button on
this screen will cause a manual switchover between exciters if the PA is “linked” to both exciters. (Note: In
a dual exciter configuration, both exciters are on at the same time, producing an RF output signal a the
same time, and the PA is considered “linked” with an exciter when the PA detects an RF output present
from the exciter as monitored).
Auto Exciter Switchover: In a Dual Drive configuration, the PA is set to automatically switch to the
standby exciter in the event a problem occurs with the on-air exciter. The PA will not automatically switch
back to the original Exciter as long as the standby Exciter is operating properly. However, the PA will

PA-U2D-C-FA User Manual
ACT-PA-U2D-USR-DOC-V2.2, 09/25/2019 Page 15 of 20
automatically switch back to the original Exciter in the event of a problem with the on-air (standby) exciter.
So the PA will continue to automatically switch to the standby exciter in the event of a problem with the
on-air exciter.
If neither of the exciters can be linked successfully (i.e. the PA does not detect a valid RF output present
from either exciter), a window will pop up, indicating “No Exciter Linked”, as shown below.
If the manual switching is successful, a window will pop up indicating “Change succeed!”, as shown
below.
If the manual switching is not successful, a window will pop up indicating “Change failed!”, as shown
below.
