General Description
The DR series DC remotes are designed to provide remote control of a conventional or trunked two way radio
base station or repeater via a leased wire line or in-house twisted pair.
The DR series is available in four different housing configurations. They are: the DR10 telephone style unit with
handset, the DR20 desktop console with desk microphone, the DR30 desktop console with built in electret
condenser microphone and the DR40 desktop console with goose neck microphone.
Standard features on all DR models include front panel PTT switch, line operated transmit indicator, off-hook
monitor function(DR10), RX and TX audio compression, two watt amplified speaker with volume control, line
continuity sensor and parallel cross mute capability.
The DR10, 20, 30 and 40 may be wall mounted by ordering the -WM option. When wall mounting the DR20
please note, no provisions are made for mounting the desk microphone.

Pre-Installation Considerations
The DR series DC remotes are designed with protection against both power and telephone line surges. This
protection circuitry requires the use of a properly grounded AC outlet. If the remote is to be powered directly from
DC the wall plug-in transformer is not used
Phone lines
The DR series is designed to work with a good quality leased metallic pair (phone line) or in house twisted pair
wiring. The maximum dc loop resistance, including the termination panel, cannot be greater than 10,000 ohms.
Parallel operation
When several remote control units are connected in parallel the total system impedance will decrease to a point
where operation is degraded.
To compensate for this effect, DR series remotes provide a dip-switch selectable 600 or 5000 ohm termination
impedance.
In parallel remote installations using the same phone line, dip switch 7 should be in the OFF position (5000
ohms), in all remotes except the last one in the chain. For multi-point installations using more than one phone
line the above procedure applies to each phone line.
Up to ten DR series DC remotes may be connected in parallel. The maximum loss between any remote and
the termination panel must not exceed 20dB.
Installation
Connections
Phone line connections are made using the supplied modular line cord. Power consist of plugging the wall pack
in to the nearest properly grounded AC outlet. If the remote is to be powered directly from a DC source, disconnect
the wall plug-in transformer from TB1 and connect a well grounded 12 to 16 volt DC supply. The positive lead
should connect to TB1 pin 1. The negative lead should connect to TB1 pin 2.
Control Current Settings - Table 1 shows the eight possible control current combinations available in the DR
series remote. Switches 1, 2 and 3 of the dip switch are used to select the desired control current format. They
are accessible on the underside of the remote.
Table 1
Field Selectable Configuration Settings
The DR series remotes are designed to be as user / technician friendly as possible and provide a wide range
of field selectable options. These dip switch selectable and jumper selectable options give the DR series great
flexibility in the field.
Table 2 illustrates the field configuration settings that are dip switch selectable.

Table 2
Jumper Settings
The DR series DC remotes have 21 solder dot jumpers on the PCB. Jumpers are considered to be "in" when
solder has been applied to form a short from one side to the other. Jumpers are considered to be "out" when no
solder has been applied and the circuit is open from one side to the other. Remove the four housing screws and
open housing to access jumpers.
The following describes field selectable jumper functions.
JU19 - Off-hook monitor function. Generates monitor current when handset is off-hook.
IN = disabled, OUT = enabled.
Must be IN for DR20, DR30 and DR40.
JU20 - Parallel Transmit Indication (PTI). Energizes PTT indicator when a parallel remote keys, locks out
TX audio and disables control current generation from this
remote.
IN = disabled, OUT = enabled.
See "Setup Adjustments" for adjustment procedure.
JU16 - Cross Mute. Mutes speaker when a parallel remote keys.
IN = enabled, OUT = disabled.
Requires PTI enabled and adjusted.
JU14 - Trunking option for 2 wire system. Allows trunking status tones to be heard in earpiece while
remote is keyed.
IN = disabled, OUT = enabled.
Can not be used for DR20, DR30 or DR40 in 2 wire system.
JU17 & JU18 - High Loop Resistance. Allows use of PTI on DC loops with 6K to 10K resistance.
IN = Loop resistance is 6K to 10K.
OUT = Loop resistance is less than 6K.
Ignore if PTI not enabled.
A description of all jumper functions appears on the schematic next to the jumper.
Line Continuity Sense
This feature will tell you, via the PTT LED, if your DC loop continuity has been lost.
If the unit is keyed and there is no DC loop continuity, the PTT LED will not illuminate. When the unit is un-
keyed, the PTT LED will flash once.
There are no adjustments for this feature.
Setup Adjustments
The following adjustments assume that the termination panel has been properly installed.
Switch # ON OFF
4 Phone line polarity is reversed. Phone line polarity normal.
5 Speaker volume can be turned all the way
down. Speaker volume can not be turned all the
way down.
6 Speaker active on-hook. Speaker active all the time.
7 600 ohm termination. 5000 ohm termination.
8 DR10 DR20

Receive Line Input Adjustment
The receive line input, R92, adjusts the audio level to the input of the compression amplifier circuitry. This
allows the threshold of compression be adjusted from -20 dBm to +10 dBm.
While applying an RF signal modulated with a 1000 Hz tone at 60% system deviation to base station receiver,
adjust the termination panel line output control for 0 dBm to the phone line. Adjust each remote as follows:
a. Connect a scope or analog AC volt meter to ground and pin 14 of U8.
b. With R92 fully counter clockwise, adjust in a clockwise direction until the AC voltage level on scope or meter
just stops increasing. This point is the threshold of compression.
c. Remove the RF Signal from the base station.
Transmit Line Out Adjustment
This level is preset at the factory for 0 dBm out to the phone line and should not require readjustment at
installation. If needed, the procedure is as follows:
1. With the handset off-hook (if applicable) depress the PTT switch and adjust the mod out pot (R63), while
speaking in a normal voice, until 0 dBm is measured across the phone line at the termination panel.
Microphone Sensitivity
R64 controls the microphone audio level into the transmit compression circuit and therefore acts as a sensitivity
control. This potentiometer has been factory set to provide adequate compression for normal voice audio with
a relatively quiet background noise level.
PTI (Parallel Transmit Indication) Adjustment
If you do not need the PTT indicator to be line operated and you are not using the cross mute feature you may
skip the following procedure.
Before making the following adjustments, please verify that: The chosen control current format matches the
requirements of the termination panel being used at the radio base station or repeater site. See Table 1 for dip
switch settings.
The remote must be connected to the termination panel via your in house wiring or leased wire line.
1) Remove the four housing screws that secure the top half of the housing. Set the unsecured top
half of the housing to the right of the remote. Do not unplug the ribbon cable from the bottom unit.
2) With the remote powered up, depress and hold the PTT switch. The red PTI LED (DS5) on the base
board, PCB in lower half of housing, should illuminate. If it is illuminated go to step 3. If it is not illuminated adjust
R176 counter-clockwise until the PTI LED illuminates.
3) Release the PTT switch. The PTI LED (DS5) should no longer be illuminated. If it is still illuminated,
proceed to step 4. If it is not illuminated, verify once more that the PTI LED comes on when the PTT switch is
depressed and goes out when it is released. If this is true then proceed to step 6.
4) Since the PTI LED (DS5) is still on you must adjust R176 clockwise until it just goes out. If you reach
the end of adjustment of R176, it clicks as you turn it, and the PTI LED (DS5) is still on, proceed to step 5. If PTI
LED (DS5) goes out, verify once more that the PTI LED comes on when the PTT switch is depressed and goes
out when it is released. If this is true then proceed to step 6.
5) Power down the remote. Install solder dot jumpers JU17 and JU18. Return to step 2.
6) Remove solder dot jumper JU20. Adjustment complete.
Circuit Analysis
Receive Audio Path
Receive audio from the phone line enters through transformer T3. The control for Receive line input, R92,
adjusts the signal level passed to the compression amplifier formed by U8. The compression amplifier operates
by sampling the output of U8-C through R107 and C57 and then rectifying it with D21 and D20. The rectified dc
voltage, which varies as the receive audio level varies, controls the impedance of Q4. The varying impedance
of Q4 controls the signal level input to U8-A. C40 and R77 control the compressor attack and decay time. U8-
D and it's associated circuitry form a high pass audio filter which reduces 60 Hz components by as much as 40
dB.
The compressor output is passed on through the front panel volume control to speaker drivers U3 and U4. The
compressor output is also fed through R94 to the earpiece amplifier circuitry.
Transmit Audio Path
Mic level audio is fed to preamp U7-A or U7-D, depending on which mic is used. Preamplified transmit audio
6
is routed through audio gate U10-A or U10-C, depending on which mic is used, to the mic level adjustment R64.
R64 sets the signal level passed to the compression amplifier formed by U2. The compression amplifier operates
by sampling the output of U2-A through R33 and C27 and then rectifying it with D5 and D6. The rectified dc voltage,
which varies as the transmit audio level varies, controls the impedance of Q3. The varying impedance of Q3
controls the signal level input to U2-C. C30 and R35 control the compressor attack and decay time. U2-B and it's
associated circuitry form a high pass audio filter which reduces 60 Hz components by as much as 40 dB.
The compressor output is gated through U6-C and fed to the phone line driver circuit of U5-A and U5-C. U5-
A and U5-C form a push-pull amplifier to drive transformer T3.
Control Current Generation
Activation of the PTT, Monitor or Hook-Switch off-hook will cause U12 pin 10, labeled High Voltage Start, to go
low. This pulls pin 4 of U1 to .77Vdc causing it to output a »15Vdc square wave at » 50kHz on pins 9 and 10. This
output is pulse width modulated by U1 to provide the appropriate voltage at HIGH VOLTAGE+ and HIGH
VOLTAGE-. U7-B is configured to limit high voltage output to 190Vdc. The voltage at HIGH VOLTAGE+ and
HIGH VOLTAGE- is continuously adjusted by U1 to maintain a constant current level which is regulated by U7-
C. The current level is determined by the control format chosen via dip switches 1, 2 and 3 (See table 1) and the
control function, PTT or Monitor, selected at the time.
