Sockets + Pin Assignment
The Interface Audio, USB, RS232, RS485 is used for the remote control of Kenwood NEXEDGE-
radios. The radios are controlled using a Funktronic Major 4a/5a control panel, that has to be
equipped with the software option Kenwood NEXEDGE. Hereby, the instructions to control the radio
are transmitted via the serial data interface (RS232), the NF is transmitted in an analog way from the
Major to the radio.

RS485 is a differential 2-wire (+GND) data interface for 2 or more participants. The maximum length
is about 1000m. Both ends of the bus need to be terminated with 120 Ohm, branches should be
short and should not include a terminating resistor.
The RS485 is already equipped with the suitable terminating resistors. For few and short connection
lines, these can remain in place. In other cases or if connection problems are encountered the surplus
resistors need to be removed (R14-R16). Another possibility to improve the connection is to reduce
the rate of the data transfer.
Ex factory, the RS485 is part of the "Line" connector and, thus, transferred in the same cable as the
AF lines. Hence, only one cable is necessary to connect 2 interfaces. Depending on the used cables,
the cable length and the number of interfaces, coupling of the data telegrams with the AF lines might
occur. In this case, the RS485 sockets can be connected using a separate cable. To disconnect the
RS485 lines of "Line" socket, open JP1 and JP2.
RS485 Interface
The LEDs at the socket "Radio/Major" (green on the right and yellow on the left) display the
different statusses of operation:
- left LED shortly flashes once per second: interface is trying to establish a connection to the Major
or the radio
- right LED is on: connection to the Major established
- left LED is on: connection to the radio established
If a connection is eestablished, the LEDs are flashing for a short time on receiving a telegram. The
left LED flashes for telegrams from the radio, the right LED flashes for telegrams from the Major.
LEDs
The interface has 2 AF inputs and outputs. The input and output at the socket "Radio/Major" is
single-ended (one pin is GND), while the input and output of the socket "Line" is potential-free.
Amplification is possible in both directions from -20dB to +10dB and can be adjusted using the
service interface.

The service interface is used to program the EEPROM registers and to adjust the potentiometer.
To use the RS232 interface for service purposes, it has to be activated at power-on of the device.
Activation is no longer possible after the interface is connected to the Major or to the radio.
When the terminal program is connected to the interface, the telegram "gk00" can be seen, which
is sent every second. Now, one hast to blindly type the activation sequence to activate the service
interface:
1.) press together button "Ctrl" + button "B"
2.) text input: "monitor" (caps lock must be deactivated - only small letters allowed)
3.) press together button "Ctrl" + button "C"
If the activation was successful, the start text of the monitor is displayed. Sending of the "gk00"
telegrams is suspended for 10 seconds after the last character that the interface receives from the
terminal program. After this, the telegram reappears, but can be simply ignored and has no influence
on the input from the terminal.
Monitor Instructions
In order to excercise a monitor instruction, type the respective characters, confirmed with Enter/
Return.
Rxxx.......................... read register xxx
Pxxx yyyyyyyy........... program register xxx with yyyyyyyy
A............................... adjust potentiometer
Q............................... software reset
X............................... quit monitor
Before connecting the interface to a Major or a radio again (e.g. to check adjusted potentiometer
values), you need to quit the service monitor using the "X" instruction. This way, the monitor can
be reactivated simply by pressing Enter/Return again. If the monitor is no longer needed and the
interface is intended for normal operation, the monitor must be left using the software reset "Q".
Alternatively the interface can be switched off and on again.
!!! The radio should not be operating while the service monitor is not completely deactivated. This
may result in malfunctions that can only be fixed by restarting the whole radio system !!!
EEPROM Registers
Register 000 Digit 1: Baud rate of the RS485 interface, set ex factory to: E (230400)

Baud 96000 115200 128000 134400 161280 201600 230400 249600
Higher bau rates result in reduced reaction times, lower baud rates allow for transmissions over
longer distances. The baud rate has to be programmed equally for all interfaces that are connected
to the RS485 bus.

Please read the operating instructions carefully before installation and setup.
The relevant regulations must be complied to when working with 230V line voltage, two-wire-
lines, 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.
