SECTION 1 GENERAL INFORMATION
1.1 SCOPE OF MANUAL
This service manual contains alignment and ser-
vice information for the Johnson DM3422 VHF Syn-
thesized Telemetry Unit
1.2 EQUIPMENT DESCRM‘ION
1.2.1 GENERAL
The Johnson DM3422 is a synthesized data trans—
ceiver (transmitter and receiver) which operates in the
132-174 MHz VHF frequency range. Transmitter
power output is 1-5 watts, SWat l3,3V nominal, and
operation is simplex or half duplex.
Va'sions of the 3422 covered in this manual are
indicated in Section l.5. The 3422 has a frequency
stability of t 2.5 PPM (see Section 3) and is available
with or without the Loader board.
The number ofchannels that can be selected
with the DM3422 model is determined by the cus-
tomer supplied synthsiaer loading circuitry.
DL3422 model is supplied with the Loader board that
has one or two channels that can be programmed.
1.2.2 DU422 WITH LOADER BOARD
The DL3422 (Part No. 013—3240—001) includes
the 8-channel Loader board (Part No. 023-3240-330),
which performs synthesizer loading through an
RS-232 DB-9 interface. in addition, this board has
circuitry which provides electronic control of the fol-
lowing:
Transmit/Receive data conditioning and gating
Carrier Detect
Power Control
Preselecmr Tracking
Modulation Flames:
Audio/Data Filtering
Sleep/Wake-up to minimize current consumption
Diagnostics that includes:
Input Voltage Sense
Input Current Sense
Ambient Temperature Sense
RSSI lndicator (RSSI Sense)
Forward/Reverse Power Sense.
The gating circuits allow the type of data ﬁlter-
ing to be selected (standard or wide band) and also
pre-emphasis/deemphasis to be enabled or disabled.
This board is programmed using an lBM‘D PC or
compatible computer and the Johnson Data Telemetry
programming soﬁware. Programming information is
stored by an EEPROM on the Loader board. Refer to
Section 3.3 for programming information.
NOTE: The synthesizer mutt be loaded each time pow-
er is turned on. Therefore, one loader board or custom-
er supplied programming circuit is required for each
dam transceiver.
1.2.3 DM3422 SYNTHESIZER PROGRAMMING
The DM3422 requires customer supplied cir-
cuitry to load the synthesizer with channel informa-
tion. The protocol that this circuitry must follow is
described in Section 3.

SECTION 2 INSTALLATION
2.l FREE-INSTALLATION CHECKS
Field alignment should not be required before the
3422 is installed. However, it is still good practice to
check the performance to ensure that no damage
occurred during shipment. Performance tests are
located in Section 6.2.
2.2 INTERFACING WITH DATA EQUIPMENT
2.2.1 DM3422 ONLY
Connector 1201 on the data transceiver PC board
provides the interface with the data equipment. This is
a 14-pin female connector with .025" square pins on
0.1 " centers (Dupont 76308-1 14). An interface cable
diagram and pin designations are shown in Figure 2-1.
This cable is not included with the data nansceiver.
The following is a general description of the vari-
ous P101 input and output signals.
Pin 1 (Ground) - Chassis ground.
Pin 2 (+133V DC Continuous) - This voltage should
be smbilized near +13.3V DC. Variations from +10V
to +16V can change power output as much as 6 dB.
Pin 3 (Tx Enable) — This input should be +3V to 13V
DC in transmit mode only.
Pin 4 (+3-16V DC Receive Enable Line) ~ This input
should be +3-16V DC in the receive mode only,
5 0.3 V DC in Tx. input impedance 2 10k ohms.
Pin 5 (Shutdown) ~ This voltage should be +3- 16V DC
:S%.
Pin 6 (T x Data Input) - Provides a response of 3:2 dB
ﬁ'om DC to 5 kHz across the RF band (referenced to
1 kHz). It also is programmable to $0.5 dB with the di»
agnostic DAC. The modulation capability is 1.8V P-P
12 dB that produces 5 kHz deviation with a 1 kHz
tone. When this input is used, a temperature compen-
sated 2.5V DC bias is required because variations in
voltage cause the frequency to change. In addition, the
transceiver regulatory compliance must be applied for
with the customer supplied modulation limin'ng/ﬁlter
circuit and chassis.
Pin 7 (Synthesizer Lock) - Output from synthesizer
lock detect circuit. Low = unlocked, high = locked.
Pin 8 (Synthesizer Enable) - Latch enable signal. A
rising edge on this input latches the data loaded into
synthesizer IC U8] 1.
Pin 9 (Synthesizer Data) - Serial data line used for
programming synthesizer lC U8] 1.
Pin 10 (Synthesizer Clock) - Soﬁware generated seri-
al clock. Data is valid on the rising edge ofthis signal.
Pin 11 (Diagnostic Enable) - This pin enables 0911
_ and U912.
Pin 12 (R581 Output) - The Receive Signal Strength
Indicator output provides a voltage that increases in
proportion to the strength of the RF input signal.
Pin 13 (Rx Output) - The data output level is 150 mV
RMS with a modulation signal of l kHz at 60°/a of max-
imum deviation. The output is DC coupled and refer-
enced to +2.5V DC. Load impedance should be >lOk
ohms.
Pin 14 (Diagnostic) - This pin is enabled by pin 11.
When the Loader board is used it has the capability to
test the operating environment through diagnostics,
The diagnostic capabilities are in Section l.2.2

SECTION 3 PROGRAMMING
3.1 INTRODUCTION
DM3422 - The information in Section 3.2
describes synthesizer progrunming protocol. This
information can be used as a basis for designing the
synthesizer programming hardware and soﬁware
required.
3.2 DM3422 SYNTHESIZER DATA PROTOCOL
Programming of the dividers and the charge
pumps are performed on a 3-Iine bus; SYNTH
ENABLE, SYNTH DATA, AND SYNTH CLK. On
initial power up four 24-bit words are required to load
the 3422 Data Transceiver. After the initial load, one
32-bit word can be used to change channels.
The SA7025 Synthesizer 1C uses four address
words; D, C, B and A (see Figure 3-4). The 24- and
32-bit words contain one or four address bits, depend-
ing on the address hits, the data is latched into regis-
ters. When the A-word is loaded, the data of these
temporary registers is loaded together with the A-
word into the work registers.
3.2.1 D~WORD
Refer to Figure 3-1.
TCXO Reference Frequency is 14.85 MHz.

The 3422 has frequency resolution of 5 kHz.
6.25 kHz or 7.5 kHz When programming 6.25 kHz
frequency resolution use FMOD=8. When program-
ming 5 kHz or 7.5 kHz frequency resolution use
FMOD=5.
Example:
(FCM) + FMOD = 25 kHz + 5 = 5 kHz
(FCM) + FMOD = 50 kHz + 8 = 6.25 kHz
(FCM) + FMOD = 37.5 kHz s- 5 = 7.5 kHz

3.2.3 B~WORD
The B-Word is 24-bits long (see Figure 3-2). It
contains the Address. Charge Pump setting factor
(CN), Binary Acceleration factors (CK. CL), and
Prescaler Type (PR).
The Charge Pump Current setting (CN) could be
changed on a channel-by-channel basis for ultimate
rejection of the Fraction N spurious responses close
into the carrier ﬁ-equency. The 3422 synthesizer has
an adjust (R823) for the fractional compensation cur-
rent. The factory preset value will allow CN to be set
to the following ranges:

e bead EP532 and C531 decouples RF.
The forward/reverse power voltages from
SSlA/B are also applied to U913IU912 for outputs
1 1201.
The low-pass ﬁlter consists of L55 l-L554,
$52, C553, C555 and C856. The ﬁlter attenuates
urious frequencies occurring above the transmit fre-
ency band. The transmit signal is then fed through
! antenna switch to antennajack 1501.
,.4 ANTENNA SWITCH (cam, cassz)
The antenna switching circuit switches the
enna to the receiver in the receive mode and the
nsmitter in the transmit mode. In the transmit
dc, +9V is applied to L555 and current ﬂows
ough diode CR561, L561, diode CR562, and
61. When a diode is forward biased, it presenm a
I impedance to the RF signal: conversely, when it is
erse biased (or not conducting), it presents a high
aedance (small capacitance). Therefore, when
561 is forward biased, the transmit signal has a
f~impedance path to the antenna through coupling
wacitor C562.
L561 and C564 form a discrete quarter-wave
:. When CRS61 is forward biased, this quaner-
16 line is effectively AC grounded on one end by

. the other end presents a high impedance to the

4.415 TRANSMITTER KEY-UP CONTROL
Q121, 0122 and Q123 act as switches which turn
on with the RX_EN line. When the line goes low
0121 is tumed off, which turns Q122 on, turning
Q123 on. This applies 13.6V to U] l 1 before the
TX_EN line goes high.
U1 1 IAIB provide the key~up and key-down con-
ditioning circuit C116 and R1 17 provide a ramp-up
and ramp—down of the 9V transmit supply during key-
up and keydown which reduces load pull of the VCO
during key-up. The conditioning provides a stable
5.5V output by balancing the 5.5V reference with the
55V regulated supply,
The output on U1 l 18, pin 7 is applied to com-
parator U1 1 ID, pin 12, the non-inverting input. The
output ofUI 1 ID, pin 14 is applied to the b ase ofcur-
rent source 0124. The output on124 is on the emit-
ter and is applied back to the inverting input ofcom-
parator U1 1 ID, pin 13. A decrease or increase on
U1 1 ID, pin 13 causes a correction by U] 1 ID to stabi-
lize the 9V transmit output. R125/R126 establish the
reference voltage on U1 1 1D, pin 13. C123 provides
RF bypass, C 124 provides RF decoupling and C125
stabilizes the output. The 9V transmit voltage is then
distributed to the circuits,

SECTION 5 SERVICING
5.1 GENERAL
5.l.l PERIODIC CHECKS
This transceiver should be put on a regular main-
tenance schedule and an accurate performance record
maintained. Important checks are receiver sensitivity
and transmitter frequency, modulation, and power out-
put. A procedure for these and other tests is located in
Section 6. It is recommended that transceiver perfor-
mance be checked annually even though periodic
checks are not required by the FCC. During the ﬁrst
year, make an additional check or two to ensure no
TCXO frequency driﬁing has occurred.
5.1.2 SURFACE-MOUNTED COWONENI'S
A large number of the components used on the
transceiver board are the surface-mounted type. Since
these components are relatively small in size and are
soldered directly to the PC board, care must be used
when they are replaced to prevent damage to the com-
ponent or PC board. Surface-mounted components
should not be reused because they may be damaged by
the unsolden'ng process.
5.1.3 SCHEMATIC DIAGRAMS AND CONDO-
NENT LAYOUTS
Schematic diagrams and component layouts of
the PC boards used in this transceiver are located in
Section 8. A component locator guide is also pro-
vided to aid in component location.
5.1.4 REPLACEMENT PARTS LIST
A replacement parts list with all the parts used in
this transceiver is locamd in Section 7. Parts are listed
alphanumerically according to designator. For infor-
mation on ordering pars, refer to Section 1.8.
51.5 TCXO MODULE NOT SERVICEABLE
The 12.5 PPM TCXO module is not ﬁeld ser-
viceable. Part changes require a factory recalibration
to ensure that the oscillator stays within its 12.5 PPM
tolerance.
5.2 SYNTHESIZER SERVICING
5.2.1 INTRODUCTION
When there is a synthesizer malfunction. the
VCO is not locked on frequency. When an unlocked
VCO is detected by the lock detector circuit, U8] 1.
pin 18 goes low (OV).
NOTE: The user-supplied circuitry mus! disable the
transmitter and receiver when an out-of-Iack condi-
tion is indicated.
When the VCO is unlocked. the fl and fv inputs
to the phase detector are usually not in phase (see Sec-
tion 4.1.2). The phase detector in Usll then causes
the VCO control voltage to go to the high or low end
of its operating range. This in turn causes the VCO to
oscillate at the high or low end of its frequency range.
As shown in Figure 44, a loop is formed by
VCO 0872, ampliﬁer 0871, and the RF IN ofUBl 1.
Therefore, if any of these components begin to mal-
function, improper signals appear throughout the loop.
However, correct operation of the counmrs can still
be veriﬁed by measuring the input and output frequen-
cies to check the divide number.
Proceed as follows to check the synthesizer l/O
signals to determine if it is operating properly.
5.2.2 REFERENCE OSCILLATOR
Check the signal at U811, pin 8. It should be
[4.85 MHz at a level of approximately 0.5V P—P. If
the TCXO module is defective, it is not serviceable
and must be replaced with a new module as described
in Section 5.1.5.
5.2.3 VCO
Output Level
The output level of 0882 can be measured with
an RF voltmeter or some other type of high impedance
meter. The minimum level after a power splitter at
R851 should be -3 dBm.

ERVICING
inntmllaliage
Check the DC voltage at C815 with a channel
ear the center of the hand. If the VCO is locked on
equency, this should be a steady DC voltage near
V. if it is not locked on frequency, it should be near
|e lower or upper end of its range (UV or 5.5V).
mnﬂnqmcx
Check the VCO frequency at R851. [f the VCO
locked on frequency, it should be stable on the
unsmit channel frequency. If the VCO is not locked
1 frequency, the VCO control voltage is probably
:ar 0V or 5.5V.

1.1 SCOPE OF MANUAL
1.1 .l INTRODUCTION
This manual contains setup and service information for the Johnson Data Telemetry (JD‘D DL-3286
Telemetry Modem. For servicing information on the MOO-series telemetry radios which may be used with this
modern, refer to the speciﬁc transceiver service manual.
1.2 MODEM DESCRIPTION
1.2.1 GENERAL
The function of a modem is to convert digital data to an analog signal which can be used to modulate an
RF carrier. The modem also converts the received signal back into its original digital data. This allow digital
data to be transferred using a wireless RF link.
1.2.2 Dlr3412, DL-3422 or Dix-34”
When the DT 3236 modem is paired with a DL-3412, DL—3422 or Die—3492, the radio modem covers the
full UHF band at 25 kHz, 12.5 kHz and 625 kHz channel steps and the full VHF band at 30 kI'IL 15 kHz and
7.5 kHz channel steps. This modern uses a 4-1.evel Root-Raised Cosine FSK modulation scheme. It operates in
a half-duplex conﬁguration and has the capability to be set up in a repeater mode.The DL-3286 modem is
capable of packetized and non-packetized damThe DL3286 supports Flow Control (F BC), DCE/DTE (Fl-2C).
DCE/D’l'E (No FEC), Data only (PEG), and Dnta~only (no FCE) protocols.
The 3286 is capable of sending and receiving data at two diﬂ'erent speeds. This can be used selectively to
change to the lower speed (if necessary). The half-channel modern has a high speed of 9600 bps and a low
speed of4800 bps.
Front panel LEDs provide visual indicadon for transmit, receive and power. Set-up software uses a
Windows® Program and includes network diagnostics capable of showing the number of packets sent, number
of packets received, data reception quality and CRC packet errors. Programming set-up provides a unique
programming 11) that allows diagnostics to be reported both locally and "over-the-air" ﬁ'um any location.
Built-in radio diagnostics are capable of reporting speciﬁc unit programming, loop back testing and radio
performance statistics (Le. RSSI, temperature, supply voltage, current, internal supply voltages, and transmitter
power).

19200 full—channel 4—leve1 FSK Modem.
4.2 RTU INTERFACE
“a
4.2.1 INTERFACE DESCRIPTION
The RTU Interface is an 115232 connection. The data format will be 8 data bits, 1 start bit, I stop bit and no
parity. The baud rate is programmable (19200 / 96001 4800 band) with the 3286 Setup Soﬁware (a Windows®
based program.) While in the setup mode, the modem uses 9600 baud.
The Modern and the RTU uses either a Flow Control protocol or an RTS/CT S Handshaking protocol.
4.2.2 FLOW CONTROL PROTOCOL
When the Flow Control protocol is used, the modem will send packetized data containing Forward Error
Correction (FEC) information. With this protocol, the Modem can be programmed to expect an ACK or NACK
for each packet sent, or the modem can packetrze the data and send as is. The CTS output of the Modem signals
(assemd), the Modern‘s receive buﬂ‘er IS NOT full. When the CTS is low (unasserted), the Modem’s receive
buffer IS fullt This is the default protocol since it sends dam in packets and utilizes Forward Error Correction.
This protocol can be used by users sending small packem (less than xx characters) who do not want to deal
with the RTS and CTS signals. the following ﬁgures show the Flow Control protocol. Figure 4.1.1 shows the
CTS signal controlling the ﬂow of data ﬁ'om the RTU. Figure 4.1.2 shows how a small packet (less than xx
characters) would not even use the CTS signal, since there were not enough characters to ﬁll the receive buffer.

4.2.3 RTS/CTS HANDSHAKING PROTOCOL
When the RTS/CTS Hmdshnking protocol is used, the modem will send raw data containing NO Forward
Error Correction information. with this protocol, the Modem CAN NOT be programmed to expect an ACK or
NACK for each packet sent. This is the protocol used by the JDT 3282 and 3276 Modems. Figure 4-3 shows the
RTSICTS Handshaking protocol, where the RTS signal resembles a PTT signal.

4.3.4 MISCELLANEOUS
The 3286 Modem is capable of sending and receiving data at two different speeds. This could be used to
automatically change to the lower speed (ifneeessary.) The half-channel modem has a high speed of 9600 bps and
a low speed of 4800 bps.
Some programmable parameters are:
0 Number of re-tries (for modern setup to receive an ACK for each packet)
0 Ability to change baud rates amoruatically (for modern setup to receive an ACK for each packet)
o A unique identiﬁcation number (65,000 numbers)
0 Mode to allow communication between two modems (with use of Unique ID)

CIRCUIT DESCRIPTIO
5.1 GENERAL
5.1.1 INTRODUCTION
The modem board (Part number 023-3286-001) is a plug-in circuit board. The three main ﬁlnctions of the
modern board include loading the synthesizer, providing the baseband modulating signal for the transmitter, and
demodulating receive audio signals The modem board lS programmed by a personal computer and software and
connects to the radio through a l4-pin connector, J 100. Programming clmnnels and other operating parameters
are provided through a DB-9 connector, A block diagram of the modem is shown at the end of Section 5.
5.1.2 TRANSMIT DATA
Transmit data ﬁ'orn the RS-232 port is level-shifted to TTL levels by U216. The MX919B modem, U210,
takes the digital data stream and modulates the analog baseband signal using a 4 Level root Raised Cosine FSK
modulation scheme Which is ﬁltered by U502 then applied to MOD_1N (pin 6) of J 100.
The MX9I9B modem 1C is a custom MX-COM 4 Level FSK packet data modem operating from 4800 to
19.2 kbps. The modem 1C adds forward error correcn'on (PEG) and data correction (CRC) informatiomAﬁer
adding symbol and flame synchronization codewords, the data packet is converted into ﬁltered 4-level analog
signals for modulating the radio. Potentiometer R508 sets the transmit deviation
5.1.3 RECEIVE DATA
Received signals are ﬁltered by band-pass ﬁlter U402-3 and the gain is adjusted with R410 to set the
comct analog levels for the modern IC. The detected audio is fed to the input of the modem 1C and also to a
symbol synchronization band-pass ﬁlter U402-1. From U402-l, the audio passes through a peak detector and
ampliﬁer U402-4 before moving to the processor which searches for a symbol sync pattern. Once the symbol

CIRCUIT DESCRIPTION
5.1 .5 POWER SUPPLIES
11604 provides 55V for the receiver 5.5REG and analog modem circuitry, while U602 provides SV for the
CPU and other digital logic.
5.1.6 MISCELLANEOUS FUNCTIONS
An error condition (when the logic voltage regulator goes out of regulation) resets the processor. U606 is a
temperature sensor used by the ﬁrmware to compensate for variations in RSSI.
The RF module's RSSI_OUT (J 100 pin 12) is read by an analog input on the CPU, which implements a
squelch threshold in soﬂware. Various internal voltages (F_B+, analog VCC, RXSV, TXSV, SWB+) are read and
the diagnostics can be displayed using the available soﬁware.
Switch 8102 puts the CPU in programming mode in which the CPU accepts new boot code from the
soﬁware.
