2.1 INSTALLATION

2.1.1 Installing the Remote Kit (KRK-14H, KRK-15B)

The KRK-14H and KRK-15B remote kit is used to remotely oper-

ate the NX-5700/5800 series transceiver.

The KRK-14H is connected to the NX-5700/5800 or KCH-19 op-

eration panel with the KCT-71 remote control cable.

The KRK-15B is connected to the NX-5700/5800 RF Deck with

the KCT-71.

Note:

The KRK-14H has the common firmware of the NX-5700/

5800.

When turning the transceiver power ON in the state from which

the firmware version of the NX-5700/5800 RF Deck and KRK-

14H is different, the firmware programming mode will start up

automatically, and “FIRMWARE PROG” is displayed on the

LCD.

2.2 CIRCUIT DESCRIPTION

2.2.1 KRK-14H

2.2.1.1 Overview

KRK-14H is an optional unit designed to separate the Mobile transceiver and Basic type panel (KCH-19) by remote control cable (KCT-

71). KRK-14H communicates with Mobile transceiver in a serial bus and controls Basic type panel. This unit consists of a power supply

circuit, audio circuit, and control circuit.

2.2.1.2 Power supply circuit

SB (Switched +B Power) is supplied from Mobile transceiver via CN1. IC1, IC2, A1, and IC4 are step down switching regulator. IC1

regulates 5.3V (53DC) from SB. 53DC is the power source of D-class audio amplifier, CAN transceiver, and regulator (IC6). IC6 reg-

ulates 5.0V (50D). 50D is supplied to level shift circuits and a part of audio circuits. IC2 regulates 3.9V (39DC) from SB. 39DC is the

power source of regulators (A1, IC3, IC4, and IC5). A1 regulates 1.2V (12D), IC4 regulates 1.8V (18D), IC3 regulates 3.3V (33A), and

IC5 regulates 3.3V (33D).

12D is supplied to MPU core. 18D is supplied to MPU, Mobile DDR, Codec DSP core, In MPU memory interface work with 1.8V power

supply (18D). The I/O section of the NOR flash memory works with a 1.8V power supply. It must be supplied after 33D is powered up.

Therefore, the 1.8V power supply of flash memory is supplied through switch IC (IC7) which is controlled by 33D. 33A is the power

source of audio circuits. Those are operational amplifiers and the analogue section in Codec IC. 33D is the power source of I/O section

of MPU, Codec, and CAN transceiver. The power source of flash memory is 33D, too. During the SB supplies, all regulators work.

2.2.1.3 Audio circuit

2.2.1.3.1 RX Audio

KRK-14H has two RX Audio input channels, AFIA+/- and AFIB+/-. And the MPU selects the one of the two channels, and input it to

codec IC (IC17). (The channel to use is notified by serial communication from RF Deck.)

The codec IC adjusts RX Audio signal amplitude equal to the value of selected volume step, and output it. That output signal is con-

verted to balanced signal by operational amplifier (IC19). And converted signal goes to Class-D audio amplifier (IC25). The audio am-

plifier is controlled to shutdown or power-up, by MPU.

2.2.1.3.2 TX Audio

KRK-14H has two microphone input channels. One is connected to Basic type panel (KCH-19), other is connected to external interface

connector (CN2). Two microphone signals are selected by analog multiplexer IC (IC20), and inputted to microphone amplifier. The

microphone amplifier consists of operational amplifier and AGC. And its output is connected to Codec IC. The total gain of amplifiers

in Codec IC is set to 0dB. The output signal of codec IC is converted to balanced signal by operational amplifier (IC13). The converted

signals are switched by analog switch IC (IC11, IC12), and output to either MICA+/- or MICB+/-. The output channel is notified from

RF Deck by serial communication.

2.2.1.4 Control circuit

The control circuit consists of MPU (IC16) and its peripheral circuits. IC16 mainly performs the followings;

(1) Serial communication between RF deck and KRK-14H

(2) Controlling the audio circuits including codec IC

(3) Controlling the display

2.2.1.4.1 MPU

The MPU is 32bit RISC processor, equipped with peripheral functions. The maximum operating clock of MPU is 288MHz, and power

source are 3.3V/ 1.8V/ 1.2V DC. The MPU controls the flash memory, Mobile DDR, the audio circuits, the Key detection IC which is

on Basic type panel, external I/O circuit, and the display (LCD).

2.2.1.4.2 Memory Circuit

Memory circuit consists of the MPU and the Mobile DDR (IC23), the flash memory (IC29). The flash memory has capacity of 256Mbit

that contains the program for the MPU and stores the data. That program can be easily updated from external devices. The Mobile

DDR has capacity of 512Mbit. The MPU copies the program from the flash memory to the Mobile DDR. The MPU uses the Mobile

DDR as a work area.

2.2.1.4.3 LCD control interface

The MPU controls LCD which is in Basic type panel (KCH-19) through the panel interface connector (CN37). LCD is controlled by

parallel bus with 16bit data width.

2.2.1.4.4 Key detection

The MPU can detect the keys of Basic type panel (KCH-19). In the Basic type panel, the keys are connected to I/O expander IC which

has key matrix function. When the key was pushed, I/O expander IC scans which key is pushed. Then an interrupt occurs for a MPU

from an I/O expander IC. The MPU reads the registers of I/O expander IC after an interrupt occurs, and checks which key is pushed.

2.2.1.4.5 External I/O

KRK-14H has external interface connector (CN2). That interface has two output and two input terminals. The output terminal is open

collector type. The input terminal has level shift circuit, it permits input the 5V signal.

2.2.2 KRK-15B

2.2.2.1 Overview

KRK-15B is an optional unit designed to separate the Mobile transceiver and Basic type panel (KCH-19) by remote control cable (KCT-

71). KRK-15B communicates with Mobile transceiver in a serial bus and controls Basic type panel. This unit consists of a power supply

circuit, audio circuit, and control circuit.

2.2.2.2 Power supply circuit

54M (5.4V DC Power) is supplied from Mobile transceiver via CN1. 54M is power source of IC2 (CAN Transceiver) and IC3 (33D, 3.3V

regulator). 33A (3.3V DC Power) is power source of Audio circuits.

33M (3.3V DC Power) is supplied from Mobile transceiver via CN1. 33M is power source of IC7 (I/O Expander).

SB (Switched +B Power) is supplied from Mobile transceiver via CN2. SB is power source of Control head interface kit (KRK-14H).

3.1 Precautions for Disassembly

3.1.1 Remove the top cover from the shield cover (KRK-14H only)

(1) There are three shield covers on the interface unit, the top covers can be removed.

(2) Use tweezers to slightly lift the edge of the top cover. <1>

(3) As you do step 2 above, vary the position you hold the top

cover as you lift it, and remove the top cover <2>.

Note:

Once the top cover is removed, it cannot be used again.

Note:

Push evenly on the top cover and be careful that you do

not bend it as you install it on the shield cover.

5.2 Replacing Interface Unit

Interface Unit Information

* The KRK-15B doesn’t have a service interface unit. Please order normal interface unit (XC3-0090-20) listed in parts list.

Method of confirming "Orginal Interface Unit" and "Service Interface Unit"

Supplied Accessories of "Service Interface Unit"

"Service Interface Unit" Data

The following data is written on the service unit.

After Changing the PCB

After changing the printed circuit board, update Firmware following the instructions.

(1) Connection procedure

Connect the transceiver to the personal computer using the interface cable (KPG-46A/46U).

Note:

You can only program firmware from the 8-pin microphone connector on the NX-5700/5800 or KCH-19 front panel.

Using the 25-pin logic interface (D-SUB 25-pin) on the NX-5700/5800 rear panel will not work.

(2) Programming

a) Start up the KENWOOD Firmware loader (KFL).

b) Set the firmware to the KENWOOD Firmware loader (KFL).

c) Turn the transceiver power ON.

d) Check the connection between the transceiver and the personal computer.

e) Press write button in the window.

When the transceiver starts to receive data, the [LOADING] display on the LCD.

The Firmware is written to DECK (NX-5700/5800) and KRK-14H at the same time.

f) If writing ends successfully, the checksum is calculated and a result is displayed.
