Installing the Station Wires and Power Wires
1. Disconnect the primary power source to the existing satellite controller.
2. Unlock the satellite cabinet front cover and the RDR unit door to access the station terminals.
3 For exterior installation, install 1/2" (13mm) flexible water-proof conduit between the satellite cabinet and the RDR
unit. See
Figure 3. Separate conduit must be installed for the 24 V a.c. power wire and station wires.
4. Using 14–16 AWG (2.5–1.5mm
2)
) stranded copper wire, route individual station and valve common wires from the
satellite terminal strip into the RDR unit. Label and identify each wire for connection to the RDR output board
terminals.
5. Secure each station wire and the valve common wire to its associated RDR station terminal; i.e., satellite station 1
connected to RDR unit station 1, etc. Refer to
Figure 4 for the satellite terminal configuration and Figure 5 for the RDR
unit terminal configuration.
6. Route 24 V a.c. power and common wires from the terminal block and secure both wires to the RDR transformer
terminals. See
Figure 5.
Note: The RDR unit requires a 24 V a.c. power supply. If installing on a controller other than the VT 4000, locate a
24 V a.c. power source from within the controller or from an outside source to connect the RDR transformer.
CAUTION: Up to three valve solenoids can be connected to each station, not to exceed 0.75A maximum
output per station. During operation, a maximum of five solenoids can be operated simultaneously, not to

Installing the Earth Ground
1. Route the green ground wire from the RDR unit transformer
terminal block to the cabinet rear plate. Secure the ground wire
ring terminal to the rear plate using the provided self-tapping
sheet metal screw. See
Figure 6.
2. Remove the lock nut from the lower right corner of the rear
plate. Install the provided star washer, copper ground lug and
lock nut. Tighten securely. See
Figure 6.
3. Connect the copper ground lug to an earth grounding device
using 6 AWG (10mm
2
) bare copper wire. Avoid bends in the
ground wire of less than 8" (20cm) radius.
Important: Make sure the satellite is properly connected to an
earth ground device such as a 5/8" x 8' (16mm x 2.5m) copper clad
rod driven into the earth at a distance from the satellite from 8' to 12’
(2.5–3.7m). The top of the ground rod should be buried 12" (30.5cm)
below grade level. Using an earth ground resistance testing device, a
reading of 0 ohms is optimum, up to 10 ohms is good and 11–30
ohms is acceptable in most cases. If the resistance exceeds the
acceptable limit, an additional ground rod can be installed at a
distance equal twice the length of first rod; i.e., 16' (4.9m). Connect the ground rods using 6 AWG (10mm
2
) bare copper
wire and test again. If the ground resistance remains high, contact your local Toro distributor for further assistance and
recommendations.
Selecting the Decoder Radio Frequency
The narrow-band frequency decoder module stores four userselectable radio frequencies. The frequencies are programmed at
the factory or by the distributor prior to delivery of the RDR unit.
A set of jumper pins, located on the RDR frequency decoder module
enables the frequency to be selected by placing the jumper on the
appropriate channel pin set. See
Figure 7.
The pre-programmed frequencies are as follows:
Channel #1 = 462.2125 MHz
Channel #2 = 462.4375 MHz
Channel #3 = 467.2125 MHz
Channel #4 = 467.4375 MHz
Note: There will be cases where the four pre-programmed
frequencies are not suitable for use in the area. The frequency
programming kit (P/N 102-1208) can be used to program any
available user-defined frequency.
Important: The base station transmitter, hand-held radio and the
RDR frequency decoder module must be set to the same frequency
to enable communication.
Assigning the Satellite Address Number
Each satellite requires a three-digit address number to enable
communication with the central controller and/or a hand-held radio.
The address numbers range from 1 (001) through 255 and is set by
the DIP switches located on the frequency decoder module
assembly. See
Figure 8.
In the down position, the switch is Off (open) and represents a value
of 0 (zero). In the On position, the closed and represents the
following address number:
Sw 1 = 1 Sw 2 = 2 Sw 3 = 4 Sw 4 = 8
Sw 5 = 16 Sw 6 = 32 Sw 7 = 64 Sw 8 = 128
To set the satellite address number, first locate the desired satellite
address in
Table 1 on page 4. Next, position each switch On or Off
as indicated on the chart.
Example: To set satellite address number 50 (050), start with all eight DIP switches in the Off (open) position, then set
switch numbers 2, 5 and 6 to the On position (
2 [2] + 16 [5] + 32 [6] = 50. See Figure 8.

Performing a Control Circuit Self Test
A self-test feature is provided to check the functionality of various
key satellite control circuits.
The test is initiated by positioning the TEST/RESET switch, located
on the frequency decoder module, to the
TEST position as shown
in
Figure 9. Testing will begin immediately. The test will repeat
continuously until the
TEST/RESET switch is positioned to the
NORMAL position.
Note: The RESET position resets the frequency decoder
microprocessor to factory defaults. To take affect, the satellite must
be powered up with the switch in the
RESET position. The switch
should be placed in the
NORMAL position after 15 seconds of
operation.
Remote Relay Function and Connection
The RDR unit frequency decoder module is equipped with a singlepole, double-throw 5.0 amp relay. The relay is intended for use in
irrigation installations which have two different irrigation systems.
Upon transmitted command from the base station or a hand-held
radio, the relay can be energized. This will stop all OSMAC RDR
functions and turn power on to the alternate irrigation system.
Another command can be sent to the RDR to turn off the relay, deenergizing the alternate system and returning control to the
OSMAC RDR. Additionally, a command is provided to disable this
feature so it cannot be accidentally activated and a different
command to enable the feature. See the
Command Code list for
specifics. See
Figure 10 for the terminal locations.
Fuse Replacement
CAUTION: For continued protection against risk of fire,
replace the fuse with the same type and rating only.
The RDR unit transformer assembly and the terminal output boards are equipped with fuses to protect the unit from
damage due to power surges and excessive current draw from the station terminals. Before replacing the fuse, check for
the probable cause, such as a shorted or improperly connected station or common wire, then replace the fuse as follows:
1. Disconnect the primary power source to the satellite.
2. Unlock the RDR unit to access the transformer assembly
and/or terminal output boards.
3. Carefully remove the blown fuse from its retaining clip.
4. Install a replacement fuse to the retaining clip. Use a 2 amp
slow-blow fuse for the transformer assembly and a 4 amp
slow-blow fuse for the terminal output boards.
5. Reconnect power to the RDR unit.
6. Test for proper operation
7. Lock the RDR unit.
Satellite Operations Using a Hand-Held Radio
Satellite operations can be initiated using a hand-held radio with DTMF keypad. The operation command codes are listed
in
Table 2 below and page 6.
Important: The base station transmitter/hand-held radio and the RDR frequency decoder module must be set to the
same frequency to enable communication.
Note: All operation commands must begin with the following keypad sequence:
*
9 followed by the three-digit satellite
address number. The command code is then entered, followed by additional digits which represent selected stations
and/or run time values. The
# key is pressed at the end of the command sequence. All station numbers from 1–9 must be
entered with a preceding
0; i.e., station 1 is entered as 01.
Example: Confirm communication to the satellite by issuing a manual station start command as follows: Press
*
9,
the three-digit satellite address code, command code
7521 01 (station 1) and #. Check for sprinkler operation. To step

Guía del usuario
Instalación de los cables de la estación y de los cables de alimentación eléctrica
1. Desconecte la alimentación eléctrica primaria al controlador de satélites actual.
2. Destrabe la tapa frontal del armario del satélite y la puerta de la unidad RDR para obtener acceso a los terminales de la estación.
3 Para la instalación en el exterior del satélite, instale un conducto flexible impermeable de 13 mm de diámetro interno entre el
armario del satélite y la unidad RDR. Vea la
Figura 3. Deben instalarse conductos separados para el cable de 24 V C.A. y para
los cables de la estación.
4. Usando cable de cobre multifilar de 2,5 a 1,5 mm
2
de espesor, dirija y conecte el cable de la estación individual y el cable común
de válvulas desde la regleta de terminales del satélite hacia la unidad RDR. Rotule e identifique cada cable para facilitar su
conexión a los terminales del tablero de salida.
5. Asegure cada cable de estación y el cable común de válvulas a su terminal correspondiente en la estación RDR; por ejemplo, la
estación 1 de satélite ha de estar conectada a la estación 1 de la unidad RDR, etc. Consulte la
Figura 4 para ver la configuración
de los terminales del satélite y la
Figura 5 para la configuración de los terminales de la unidad RDR.
6. Dirija el cable de alimentación eléctrica de 24 V C.A. y el cables común desde el bloque de terminales y asegure ambos cables a
los terminales del transformador de la unidad RDR. Vea la
Figura 5.
Nota: la unidad RDR necesita una alimentación eléctrica de 24 V C.A. Si se instala en un programador que no sea el VT 4000,
localice una fuente eléctrica de 24 V C.A. desde el programador o desde una fuente externa para la conexión del transformador
de la unidad RDR.
PRECAUCION: hasta 3 solenoides de válvula pueden conectarse a cada estación, sin exceder de una salida máxima
de corriente 0,75 A por estación. Durante la operación, hasta cinco solenoides como máximo pueden operarse
simultáneamente, sin exceder de un consumo máximo de corriente de 1,25 A.
