Operating and installation instructions
RF-KIT Power Amplifier RF2K-S
3.2 Control elements and connections
1 Power switch On/Off (1) (main switch)
This rocker switch switches the device on / off .
2 Touch screen - GUI
This Touch screen controls the device in all operating states.
Also you receive context-related information about the operating
status of the device.
3 ANT 3
50 Ω antenna socket SO-239 (PL-259)
4 ANT 4
50 Ω antenna socket SO-239 (PL-259)
5 ANT 2
50 Ω antenna socket SO-239 (PL-259)
6 ANT 1
50 Ω antenna socket SO-239 (PL-259)
When device is switched off , ANT 1 (6) is looped through.
7 PTT
RCA connector for transmit/receive switching
At the center contact (+) of the connector PTT (7) +5 V are
present.
8 Power On Extern
RCA connector for remote control: The device can be switched on re-
motely by ap 12V DC (at least 10 V, max 15 V!) to the center
contact. The power switch On/Off (1) must be switched off (“0“).
When DC voltage drops, the PA switches off .
9 Power jack
A plug for this power socket is included and can be wired to the user
supplied power cord capable of 16 Amps, that meets their countries
power plug requirement.
10 Fuse - automatic circuit breaker 16 A
If this automatic circuit breaker triggers several times in succession,
this usually has a valid reason!
WARNING!
Do not open the device by yourself, contact the manu-
facturer!
