User & Technical Manual
TX20000U-KLC
JP4/7 In LOW PWR Corresponds to the REDUCED POWER button of the con-
trol unit
JP4/8 In AUDIO ALARM
EXC. 1
Audio alarm of exciter 1. This input, when active, indicates
an alarm on exciter 1. If the TX20000U-KLC is in automa-
tic changeover modality, if the exciter 1 is on air and if this
signal remains active for a time lag equivalent to the time
setted in the Settings menu at line Exc. Wait time, the chan-
geover procedure between the exciters will be started.
JP4/9 In AUDIO ALARM
EXC. 2
Same as AUDIO ALARM EXC. 1 for exciter 2.
JP4/10 / GND Grounding contact.
JP8/1 In ALARM RE-
SET
Corresponds to the ALARM RESET button on the control
unit
JP8/2 In RESRV. 1 Reserve 1 input. When this input is active, the failure is re-
gistered by the software in the Alarms menu. For example it
can be connected to a switch that indicates that the door of
the station is open or to a sensor of a power reserve of an
electric generator. In this way, by consulting the menus of
the unit, it is possible to trace the moment at which (time and
date) the failure occurred.
JP8/3 In RESRV. 2 Same as JP8/2
JP8/4 In RESRV. 3 Same as JP8/2
JP8/5 In RESRV. 4 Same as JP8/2
JP8/6 In EXCITER
CHANGEO-
VER CMD
This command launches the changeover procedure betwe-
en the exciters. It has the same function as when you press
the OK button when selecting line On air exciter in the menu
Exciters. In order to launch the changeover between the
exciters through this command, the manual changeover
modality should be formerly selected through the correspon-
dent button on the control unit or through the JP8/7 jumper,
having however the unit in “Remote” modality.
JP8/7 In EXCITER
CHANGEO-
VER
Corresponds to ther EXCITER CHANGEOVER button of
the control unit
JP8/8 / GND Ground
JP16/1 Out +12V dc Power source. A maximum of 100 mA can be absorbed
between this jumper and JP16/2. This power source can
be used if the user wants to enter the comands following a
positive logic (high voltage - active comand)
JP16/2 Out +12V dc Same as JP16/1
JP16/3 / GND Ground
JP16/4 / GND Ground
JP22/1 I/O TX/RX + Bus RS 485. Please note that this serial port is operational
only when the unit is in “Remote” modality.
