General Features
The new line interface FT634a is completely constructed in SMD-technology. The connections are
pin-compatible with the former version, but instead of male connectors there are female connectors.
The line interface is used to remotely operate a two-way radio by a 2- or 4-wire connection. It is
possible to bridge very long distances depending on the cable attenuation.
Features
- 2- or 4-wire connection (selectable by jumper)
- Impedance 600 Ohm or Zr (selectabel by jumper) (Zr only for 2-wire)
- Connector radio device --> AF-in/output and PTT-out
- Serial interface RS232 to adjust and program
- All levels adjustable with RS232
- All AF-in/outputs galvanically separated (transformer)
Version FT634a TRC
In version FT634aTRC the pilot-tone encoder is replaced by a TRC encoder. Hence, no pilot-tones
can be decoded but only TRC tones.
The following parts of the TRC protocol are supported:
- Guard Tones with the frequencies 2100Hz, 2175Hz und 2325Hz
- a following Function Tone with frequencies from 650Hz to 2050Hz and the following functions:
- PTT/ channel 1 - 8
- repeater on / off (optional)
Ex factory, the FT634a TRC is programmed with common standard values. Only the desired Guard
Tone frequency must be programmed in register 040, digit 1.
The FT634a TRC is available in two different housings:
- black flange aluminum housing
- 19 inch plug-in unit
Channel Remote Switching
Channel remote switching is achieved via the transmission of different Function Tones.

Transmitter control
The transmitter control is activated as soon as the AC-line receives and decodes the pilot tone. Then
the PTT-output is switched by a potential-free relay. The PTT-output can also be controlled by DC- or
AF-decoding (register 053/1).
Functions of the LEDs
The green LED is on when the TRC sequence is decoded by the AC-line or a DC potential is applied
or AF is decoded depending on the configuration. The green LED blinks when there is a decoding
but the switching of the transmitter relay is suppressed.
The
yellow LED is on when the pilot tone was activated or DC applied to the line or the AF connected
to the line. The yellow LED blinks when the activation of one of the afore-mentioned functions is
suppressed.
Examples
LED green transmitter relay on
because
- Pilot tone was decoded or
- DC was decoded or
- AF was decoded
(blinking see description)
LED yellow
- Pilot tone turned on or
- DC applied and
- AF connected to the line

Jumper
Different configurations can be adjusted with the internal jumpers . For example you can choose
between 2- or 4-wire connections. The functions of the different jumpers are printed directly onto the
circuit board.
Jumper setting normal, 2D, Zr, AC (ex factory)
2D = 2 wire
4D = 4 wire
Zr = complex impedance
600 = real impedance 600 Ohm
AC = remote control by AC voltage

Please read the operating instructions carefully before installation and setup.
The relevant regulations must be complied to when working with 230V line voltage, two-wirelines, four-wire-lines and ISDN-lines. It is also very important to comply to the regulations
and safety instructions of working with radio installations.
Please comply to the following safety rules:
- All components may only be mounted and maintained when power is off.
- The modules may only be activated if they are built in a housing and are
scoop-proof.
- Devices which are operated with external voltage - especially mains voltage may only be opened when they have been disconnected from the voltage source
or mains.
- All connecting cables of the electronic devices must be checked for damage
regularly and must be exchanged if damaged.
- Absolutely comply to the regular inspections required by law
according to VDE 0701 and 0702 for line-operated devices.
- Tools must not be used near or directly at concealed or visible power lines
and conductor paths and also not at and in devices using external voltage –
especially mains voltage - as long as the power supply voltage has not been
turned off and all capacitors have been discharged. Electrolytic capacitors
can be still charged for a long time after turning off.
- When using components, modules, devices or circuits and equipment the
threshold values of voltage, current and power consumption specified in the
technical data must absolutely be complied to. Exceeding these threshold
values (even if only briefly) can lead to significant damage.
- The devices, components or circuits described in this manual are only
adapted for the specified usage. If you are not sure about the purpose of the
product, please ask your specialized dealer.
- The installation and setup have to be carried out by professional personnel.
