DTD-16 + G2 Installation and Operation Manual
OVERVIEW
Product Overview
The DTD-16 + G2 is a full-featured DTMF tone/sequence decoder that is user pro-
grammable to decode single tones or sequences up to six tones in length which can
be assigned to any one of eight SPST normally open relays, eight open collectors
and the USB/RS-232 serial ports.
The DTD’s relay and open collector outputs can be programmed to close for the
duration of tone, pulse immediately after completion of detection, wait a pro-
grammed (up to 9.99 seconds) length of time after detection, or latch/unlatch.
Programming is performed using a non-dedicated PC’s USB or RS-232 serial port
equipped with a serial terminal program like HyperTerminal, Tera Term, or PuTTY.
Features/Benefits
• Decodes all 16 DTMF tones or user-programmed tone sequences.
• 8 SPST relay outputs and 8 open collector outputs triggered by tones or tone
sequences.
• Front panel tone audio input level control with a range of -20 to +24dbu
• Adjustable tone detection time.
• Front panel relay status, power, tone activity, program mode, and activity LEDs.
• Programmed via USB or RS-232 serial connection.
• Mode configuration via front panel dip-switches.
• Relay, open collector, and tone audio connections on removable euro-block screw
terminal connectors to simplify wiring and service, mating plugs are supplied.
• Fully RFI proofed.
• Surge protected internal power supply, 9 VDC universal desktop power adapter
with IEC inlet included.
• Up to three units may be mounted on the optional RA-1 rack shelf, using four
supplied Velcro feet. Desktop and wall mounting is also possible. WEBSITE:

DTD-16 + G2 Installation and Operation Manual
INSPECTION
Inspection
Please examine your DTD-16 + G2 carefully for any damage that may have been
sustained during shipping. If any damage is present, please notify the shipper imme-
diately and retain the packaging for inspection by the shipper. The package should
contain the DTD-16 + G2, a power supply, a USB-A/B cable, and an “S9” RJ11-to-
DB9 cable. Manuals may be downloaded from our web site.
Installation/Operation
Power
Connect the 2.1mm barrel type center positive power connector into the unit and the
9 to 12 VDC power supply with domestic connector into a 120 Vac 50-60 Hz power
source.
NOTE: Never use any type of power supply other than the specified/supplied power
supply. Check the power jack on the back of the unit to determine which power sup-
ply is required.
Surge Protection
The DTD-16 + G2 has built-in resistance to voltage changes; we recommend that
you use a power surge protector or line conditioner on the incoming AC line.
Lightning strikes and/or other high voltage surges may damage your DTD-16 + G2
and connected equipment if it is not properly protected. For lightning protection
devices, check out www.polyphaser.com and www.itwlinx.com.
UPS Standby Power System
We recommend that you connect your DTD-16 + G2 to a UPS standby power sys-
tem. A UPS helps minimize the risk to the DTD-16 + G2 and provides power dur-
ing a power outage. WEBSITE:

Audio Input Gain Adjustment
The front panel “INPUT LVL” control may be used to adjust the DTMF tone detec-
tion sensitivity from –20dBu to +24dBu. This control should be adjusted for solid
DV LED indication while DTMF tone audio is present.
DTMF Tone Detection Jumper Settings
JP1 = DTMF Tone detection jumper (Guard time)
The DTD is equipped with a 4-position jumper, labeled “JP1” on its PCB. This is
used to adjust how quickly DTMF tones are detected. The settings are as follows:
Fast = 50ms ON / 50ms OFF
Medium = 100ms ON / 100ms OFF. (Default)
Slow = 150ms ON / 150ms OFF.
USB PGM Port
This type B USB port is used to connect the DTD-16 + G2 to a computer for con-
figuration via a virtual COM port. See the “Programming” section of this manual for
more information.
RS-232 Serial PGM Port (RJ-11 Jack):
This RJ-11 jack is used to connect the DTD-16 + G2 to a computer’s COM port for
configuration via RS-232 serial using the included reverse modular cable with 9-pin
“S9” female D-sub adapter. See the “Programming” section of this manual for more
information.

4. Enter a time delay value of 0.00 to 9.99 seconds as a three-digit value (000-999).
Do not enter the ".", it will be entered automatically. This is the time that will
elapse after a command is received and before the output is activated. Default
time delay before activation is 0.00 seconds. A “- “(dash) will be displayed after

DTD-16 + G2 Installation and Operation Manual
PROGRAMMING
Output Modes
Momentary
If you have selected the momentary function for this output channel, you can pro-
gram two codes up to 5 digits for the first code and 6 digits for the second code that
can be used to activate that output. If your code is shorter than 5 digits enter a “/” at
the end of the first data string. This will cause a new line to be displayed. Enter the
second code you want to momentarily trigger. If the string is less than 6 digits press
the “Enter” key. The codes for that output will now be saved and you can go on to
programming another output. The momentary output closure duration is 1 second.
Momentary Programming Example: To program output 1 for momentary for code
123 and 321 with a time delay of 4.25 seconds before activation:
01
0
425
123/ 321(CR)
Latch
For the Latch function, the first code will be used to latch the output on, and the sec-
ond code to turn latch it off. Program the “ON” code, from 1 to 6 digits. If it is short-
er than 5 digits, terminate with the “/” character. A new line will be displayed. Now
enter the code you want to use to turn OFF that output. It must be from 1 to 6 digits
long. If it is short- er than 6 digits terminate with the “Enter” key. You cannot enter
the same code to latch an output on and turn it off.
Latch Programming Example:
To program output 2 for 456 latch on, 654 latch off with no time delay:
02
1
0.00
456/654(CR)
Exclusive Latch
For the Exclusive Latch function, the first tone/code will be used to latch the output
on, and the second tone/code to turn it OFF, if desired. You do not need to enter an
OFF code. In Exclusive latch mode, when any exclusive latch output is selected, all
other exclusive latch outputs will be reset. Enter the “ON” code, from 1 to 5 digits.
If it is shorter than 6 digits terminate with the “/” character. A new line will be dis-
played. Now enter the code you want to use to turn off that output. It must be from
1 to 6 digits long. If it is shorter than 5 digits terminate with the “Enter” key. You
cannot enter the same code to latch an output on and turn it OFF.
Exclusive Latch Programming Example:
To program output 2 for 789 x-latch on with time delay of .10 second:
02
2
010
789(CR)

DTD-16 + G2 Installation and Operation Manual
PROGRAMMING
Dip-switch Settings
By default, all four dip-switches are in the up/off position which sets the DTD to its
normal operating mode and programming. The following alternate operating modes
are available via the front panel configuration dip-switches:
DIP-1
If DIP-1 is turned ON; all momentary outputs will become key-follow outputs. This
means that the selected output will turn ON when the last digit of the momentary
code is decoded and stay on for as long as that digit is being decoded. This is useful
for remote pan-tilt camera control.
DIP-2
When DIP-2 is ON, the “#” character will be translated to a CR/LF (0Dh 0Ah) on the
ASCII RS-232 output. This allows you to use the “#” as an “Enter” key and is useful
for using DTMF to remotely control equipment that requires a CR/LF termination.
DIP-3
When DIP-3 is ON, codes programmed into odd channels, 1,3,5,7, etc., will operate
relay one. Even channels, 2,4,6,7, etc., will operate relay 2. Relays 1 and 2 can be
programmed to with any mode; momentary, latching, or exclusive latching.
DIP-4
When DIP-4 is ON, Relays will be engaged on the trailing edge of the DTMF sig-
nal in both momentary and latching modes.
Restoring to factory defaults:
The default program values may be reloaded at any time by removing power from
the DTD-16 + G2, holding down the PGM button and plugging in the power and
then releasing the PGM button after a few seconds. The PGM LED will blink once
after the defaults are loaded.)
