DESCRIPTION
The model 3000R-103A Dual Tone Sender is a preprogrammed CATV Cue Tone generator
designed to place DTMF (Touch-Tone*) cues on CATV program audio. The cue tones are
transmitted to provide CATV systems with unattended switching and can signal beginning and
ending of: - Daily Programming
- Program Segments
- Local Announcements or Commercials
The model 3000R-103A can provide up to eight Cue Tone codes; four ON and four OFF.
Internal Cue Tone Decoders monitor program audio and provide verification that the cues have
been properly transmitted.
Front panel pushbutton switches and indicators permit operation; rear panel terminals allow
external switches and indicators to be added if desired.
*Touch-Tone is a registered trademark of AT&T

6
INSTALLATION
Three terminal strips are provided on the rear panel of the model R103A for external
connections.
PROGRAM AUDIO CONNECTION:
Cue Tones can be inserted on the same carrier as the program audio or inserted on their own
carrier. If they are to be inserted on the program audio carrier, it is necessary to ensure that no
program audio is present while cue tones are being transmitted. Therefore, the program audio
should be routed through the normally closed contacts of the 3000R-103A’s balanced audio
relay.
A. Open the program audio line and connect the audio source across TBI, terminals 11 and 12.
B. Take the audio output from TB2, terminals 11 and 12.
NOTE: In the event of power or equipment failure the 3000R-103A will not interrupt the program
audio.
If the Cue Tones will be inserted on their own audio carrier, make the connection in step B
above.
MONITOR AUDIO CONNECTION:
Program monitor audio must be wired to TB3, terminals 11 and 12 to provide verification that the
cue tones have been properly transmitted. To accomplish this, jumper TB2 terminals 11 and 12
to TB3 terminals 11 and 12.
If program monitor audio is not available, TB3 terminals 11 and 12 may be wired directly to the
program audio source if desired. The monitor audio input is transformer coupled (600 ohms) to
the internal decoders.
REMOTE SWITCH CONNECTIONS:
Barrier strip TB1, terminals 1 through 9 provide connections for installation of remote switches to
activate cue tone codes.
Momentary pushbutton switches can be wired from any or all terminals 1 through 8, to terminal
9. Momentarily grounding any terminal 1 through 8 will cause the 3000R-103A to transmit the
code controlled by that input.

OPERATION
When the Model R103A is first plugged into a 117 VAC outlet the front panel red indicator lamps
will be “ON” for each channel that is installed.
Pressing the front panel ON switch for any active channel will cause the R103A to send its
preprogrammed Cue Tone out on TB2, terminals 11 and 12. When equipped with 3223B-2
transmission begins when switch is pushed.

ADJUSTMENTS
All adjustments are made with respect to barrier strip TB2, terminals 11 and 12.
CUE TONE LEVEL:
A screwdriver adjustment in the center of the rear panel is provided for adjustment of the Cue
Tone level into the program audio. Maximum audio level is obtained by turning this control fully
clockwise.
The Cue Tone level on the program audio should be adjusted for –12 dBm (200 MV RMS). The
Model 3171B (A4 position) has an on board level adjustment R10. By placing the rear panel level
adjustment in its center position the model 3171B R10 can be adjusted counterclockwise to
decrease the Cue Tone level to the desired level.
CUE TONE DELAY:
The delay time between a switch closure and the beginning of a Cue Tone transmission may also
be adjusted. The Model 3223B-2 (A5 position channel 1 and 2) and or (A2 position channel 3 and
4) has an on board adjustment R12. Turning R12 clockwise will lengthen delay time between a
switch closure and the beginning of a Cue Tone transmission, this factory set at a one second
delay.
CUE TONE TRANSMISSION RATE:
The Cue Tone transmission rate may be adjusted for other that the factory setting of 10 Hz (50 ms
first pulse width). The Model 3223B-2 (A5 position channel 1 and 2) and/or (A2 position channel 3
and 4) has an on board adjustment R11. Turning R11 clockwise will increase the transmission
rate; 12.5 Hz. Equals 40 ms first pulse width; 14.3 Hz. Equals 35 ms first pulse width.

Audio Input Connection:
The audio input is connected at pins '6' and '5' (circuit common). The 3185E is factory set at 10
k input impedance; unbalanced. This audio input may be changed by the customer to have a
600 termination instead of 10 kΩ, and also to be balanced instead of unbalanced. Consult the
CUSTOMER OPTION section for more explanation.
‘Set’ Input Connection:
The ‘Set’ input is connected at pin 'D', and when pulsed to circuit common will energize the
output relay. The output relay will remain energized until the proper 'OFF' code is received or
the ‘Reset’ input is pulsed to ground. This input is level sensitive and requires a minimum pulse
width of 20 msec. to circuit common to activate or de-activate the output relay. The ‘Set’ input
has precedence over all functions except ‘Reset’.
If the 3185E's ‘Set’ input is pulsed to circuit common while decoding a code sequence it will
clear previous valid digit(s) decoded after the ‘Set’ input returns to a ‘high’ state.
‘Reset’ Input Connection:
Momentarily connecting pin 'E' to circuit common will cause the 3185E to reset. This input is
level sensitive and requires a minimum pulse of 20 msec. to circuit common to reset the card.
The ‘Reset’ input dominates over all other functions.
NOTE: The 3185E will ignore all commands or code sequences until the ‘Reset’ input is
removed from circuit common.
Relay Output Connections:
The 3185E provides a dual Form C relay output. The output relay will energize whenever the
preprogrammed 'ON' code sequence is received or the ‘Set’ input is momentarily connected to
circuit common. If the output relay is set to ‘momentary’, the output relay will activate
approximately 40ms after the last valid digit is received and stay on as long as the last valid
digit is present. If the output relay is set to ‘latching’, the output relay will remain energized until
the programmed ‘OFF’ code sequence is received or the ‘Reset’ input is momentarily connected
to circuit common.

Power Supply Input:
The power supply input is connected to pins '8' (+12 VDC) and '3' (circuit common). The 3185E
requires a power supply capable of providing 50mA minimum, and regulation of the +12 volt,
±10 %.

FIGURE 3 Jumper Locations
Input Impedance:
Input impedance may be either 10 kΩor 600 Ω. The J2 jumper determines the input impedance
of the 3185E. Install a jumper at position J2 to terminate the audio input in 600 Ω. Consult
FIGURE 3 for the J2 jumper location.
Input Balanced/Unbalanced:
The input may be selected to be balanced or unbalanced. The J1 jumper determines whether
the input is balanced or unbalanced. Removing the short from J1 will make the input balanced.
Consult FIGURE 3 for the J1 jumper location.

10
5 Minute Restoral:
The 3185E may be selected to restore the output status for a power interruption of less than
five minutes. The 3185E is factory set to enable this restoral. The J7 jumper is open. To disable
the five minute restoral install a jumper on J7. Consult FIGURE 3 for J7 location.
Momentary Output for ON & OFF:
This setting provides a momentary output relay activation for both the ON sequence and the
OFF sequence. Momentary duration is 1 second. To enable this feature, install both J3 and J4.
Output Relay:
The output relay on the 3185E may be set in three different modes of operation; latching,
momentary or alternate action (toggling). The 3185E is factory set to latching.
Being set at latching means the output relay will energize when the pre-programmed 'ON' code
is received or the ‘Set’ input is momentarily connected to circuit common. The output relay will
remain energized until the preprogrammed 'OFF' code is received or the ‘Reset’ input is
momentarily connected to circuit common.
When the output relay is programmed to operate in the momentary mode, it will energize for the
duration that the last valid digit is present. In the momentary mode the 3185E will not respond
to its pre-programmed 'OFF' code.
Alternate action programs the relay for latching (toggling) relay output. In this mode the output
relay energizes and de-energizes with the same pre-programmed 'ON' code sequence.
10 Second Pulse:
If both ‘Set’ and ‘Reset’ are low and the relay mode is ‘momentary’, then when a valid ‘ON’
sequence of digits is received, the relay is turned on for 10 seconds then ‘OFF’ – even if the last
tone is still present. The decoder will ignore all tones and ‘Set’ and ‘Reset’ activities during the
10-second period. Applies only to firmware version 80154-1.10 and later.
The programming of jumpers for the output relay is shown below. Consult FIGURE 3 page 7 for
