The three water detection sheets are attached to this unit.

These sheets are used to judge whether water has entered inside of this unit due to submergence, etc.

Judgment method
When the water detection sheet is When the water detection sheet is

t
If the water detection sheet gets wet and becomes blurred, it does not return to the original state even after
it is dried. The water detection sheet does not react to the dampness. It reacts only to the dew drop and
water drop.

Procedure after judgment

When the water detection sheet is blurred, replace it referring to Section 3-3-1.

The item list in the test mode used for operation confirmation is described below. To enter each item,
hold down the [SET] button. The setting of each item can be switched using [+] and [_] buttons. There
are items in which the change in setting brings a violation of the law. For the item whose change is
prohibited, therefore, do not change the setting. Turn on the power again when you changed the setting
incorrectly. The change in setting may be able to be recovered.

Entering the test mode

1. Turn on the power of this unit.
2. Move a menu to VERSION.
3. Hold down the [SET] button for two seconds or more.
4. Press the [+], [_], and [+] buttons sequentially.
5. Lastly, hold down the [_] button for two seconds or more.

Exiting the test mode

1. Turn off the power of this unit.

7-1. Circuit Description

This unit consists of the following boards.

. TX-172 board
. DPR-396 board
. RM-215 board
. LED-498 board
. CN-4088 board
. CN-4078 board (for H (CE) and L (CE) destinations) or CN-4148 board (for CN, UC, G (J), and MH (J)
destinations)

7-1-1. TX-172 Board

The TX-172 board mounts the circuits below.

. Power circuit
. Audio circuit in the range of the head amplifier to the A/D converter
. PLL circuit that oscillates and controls the carrier in the bandwidth of 470 MHz to 810 MHz and 1240
MHz to 1260 MHz
. Orthogonal modulation circuit (that modulates an IQ signal using the carrier generated by the PLL
circuit)
. High-frequency amplifier circuit

Power circuit (A part of reference Nos. 600 to 699 and 700 to 799)
. IC600 and IC601 are the step-up/down DC-DC converter.
. IC600 generates +5.2 V. It is mainly used in the audio circuit and RF circuit.
. IC601 generates +3.1 V. It is mainly used in the audio circuit or RF circuit and digital circuit.
. The IC605’s peripheral circuit detects the remaining amount of a battery. When the voltage of the
battery becomes less than about 1.7 V, it forcibly turns off IC609 (separates the battery from a circuit) to
prevent the battery from liquid leakage.

Audio circuit (Reference Nos. 500 to 599)

. The head amplifier circuit consists of IC500 and IC504.
. The gain of the head amplifier is changed by switching the internal switch of IC500.
The attenuator in the input stage is turned on and off by controlling PH501 to PH503.
. The audio signal amplified using the head amplifier is converted from analog to digital using IC570.
. Up to the input block of IC570 is treated as the analog audio circuit.

PLL circuit (IC808’s peripheral circuit)

IC808 receives frequency setting data from CPU (IC402 on the DPR-396 board) and controls the oscilla-
tion frequency of a carrier, which VCO802 outputs, with the oscillation frequency of X801 as standard.

Orthogonal modulation circuit (IC802’s peripheral circuit)

IC802 modulates the I/Q signal, input from FPGA, to the carrier input from VCO802.

DWT-B30 7-1 (E)

High-frequency amplifier circuit (Reference Nos. 800 to 899)
IC814, Q801, and IC815 amplify the modulation signal and output it to the antenna connector (on the CN-
4088 board).
CPU (IC402 on a DPR-396 board) controls IC805 and IC807 and adjusts the output level of IC802 or the
gain of the amplifier circuit Q801.
When the high-frequency amplifier circuit is set to 25 mW output, switch ICs IC811 and IC812 are
switched so that the modulation signal passes through IC815.
EEPROM (IC803) memorizes destination information, CH plan data, or various adjusted values of the
amplifier circuit.

7-1-2. DPR-396 Board

System control circuit (A part of reference Nos. 400 to 499 and 500 to 599)
IC402 (CPU) performs the control of this unit system such as USB control, OLED display control, ex-
terna button recognition, FPGA configuration, and remote CPU control.

FPGA circuit (Reference Nos. 200 to 299)

IC201 (FPGA) performs digital processing such as audio LCF, audio compression processing, and digital
modulation (QPSK).
IC201 also generates the digital signal such as internal signal generator and BER measuring signals
(PN9).

I/Q DAC (Reference Nos. 300 to 399)

IC300 converts the digital signal, modulated and output using FPGA (IC201), into the analog I/Q signal.

Power circuit (A part of reference Nos. 700 to 799 and 200 to 299)
. IC724 is the regulator that generates the power supply of +3.7 V from USB power supply.
. IC721 is the step-up/down DC-DC converter that generates the power supply of +2.5 V, used in the
FPGA, from the power supply of +3.7 V generated using the battery or IC724.
. IC702 is the step-up converter that generates +13.5 V for OLED from the power supply of +3.1 V.
. IC720 is the regulator that generates the power supply of +2.8 V, used for driving of the RF circuit,
remote circuit (on the RM-215 board), or display LED, from the power supply of +3.1 V.
. IC202 is the step-down regulator that generates +1.2 V, used in FPGA, from the power supply of +3.1 V.

7-1-3. RM-215 Board (Reference Nos. 2000 to 2999)

The RM-215 board mounts CPU (IC2000) and transceiver IC (IC2001) that perform remote control opera-
tion as the function of this unit.
The bandwidth of 2.4 GHz is used for the transmit frequency.
IC2000 is CPU and IC2001 is the transceiver.
The transmission output-adjusted value and remote-control ID are memorized by the internal EEPROM
of IC2000.
