DW-CP16 Compressor™ User Manual
Digital Watchdog® 15 www.digital-watchdog.com
Connecting Digital Input / Output Devices
Depending on your surveillance needs, you may connect digital input / output devices to your
encoder.
Digital Input (DI) devices can be used to notify the encoder of an activity in the camera on the
encoder site. DI can be triggers of events. For example, you can connect a “panic button” to the
encoder; as such when the panic button is pressed, the alarm signal will be sent through the
encoder. Other common DI device applications are emergency button, smoke detector, passive
infrared sensor, etc.
Digital Output (DO) devices are external devices that are activated by the encoder upon an
event within the encoder (e.g. video connection is lost, etc.) or triggered by motion in the
camera site among others. For example, you can connect an “alarm horn” to the encoder; as
such when an event occurs on the camera side (e.g. detected intruder), the alarm horn will
sound. Other common DO device applications are motion-triggered lights, electric fence,
magnetic door locks, etc.
The digital input and output pins of the Compressor are configurable. Either a digital input or
digital output device can be connected to a particular DIO pin. Once connected, the pin must
be defined through the Web Configurator. The Compressor supports 16 DIO ports.
Four (4) DIO ports share the same terminal block with four (4) audio input ports. See samples
below:
1. Loosen the screw of the pin and insert the wire through the pin slot.

2. To connect digital input / output devices (DI/DO), map the pins to one of the pin
combinations below:
Device Pin Label Mapping Instructions
Digital Output (DO) DIO (port number) Connect the wires of the output
device to a DIO and DIO 12V.

Digital Input (DI) DIO (port number) Connect the wires of the input
device to DI and DIO GND.
DIO GND
NOTE: For every digital output device, a wire must also be mapped to the 12V pin. For
every digital input device, a wire must also be mapped to the GND pin. The GND and 12V
pins may be mapped with more than one device.
3. Tighten the screws to secure the wires within the pin slot.
4. Connect the terminal block to the corresponding DIO connector of the encoder.
5. Configure the DIO ports in the Compressor’s Web Configurator.

2. Connect the wires of the audio input device to AI and AI GND.
NOTE: The AI GND pin may be mapped with more than one audio device.
3. Tighten the screws to secure the wires within the pin slot.
Connecting an Audio Output Device
The encoder has one audio output port. The audio output (AO) port shares the same terminal
block with RS-422 / RS-485 Port 1.
NOTE: To ensure optimum performance, use active or powered speakers for audio out.
To connect an audio output device, do the following:
1. Loosen the screw of the pin and insert the wire through the pin slot.
2. Connect the wires of the audio output device to AO and AO-GND.
3. Tighten the screws to secure the wires within the pin slot.
4. Connect the speaker to a power source.
Connecting a Serial Device
The encoder can be connected to a camera with Pan-Tilt (PT) functions using the serial port
connector, allowing the encoder to control the camera’s pan and tilt using the RS-485 or RS-
4522 ports. There are two (2) serial communication ports available on the encoder.
1. Loosen the screw of the pin and insert the wire through the pin slot.
2. Map the wires from the PT device to the encoder using the supplied terminal block
according to one of the tables below.

Accessing the Encoder
Configure the IP Addresses
In order to communicate with the encoder from your PC, both the encoder and the PC have to
be in the same network segment. In most cases, it means that they both should have very similar
IP addresses, where only the last number of the IP address is different from each other. There
are 2 different approaches to IP Address management in Local Area Networks – by DHCP Server
or Manually.
Using DHCP server to assign IP addresses:
If you have connected the computer and the encoder into a network that has a DHCP server
running, you do not need to configure the IP addresses. In such case, the encoder will
immediately be ready for the access from the PC. The encoder will be assigned all its network
settings automatically to follow the current network’s settings.
The quickest way to discover the encoders in the network is to use the UPnP function supported
by the Compressor. Press the “Network” icon on your PC, and all the encoders on the local area
network will be discovered by Windows.
Double-click on the encoder model to launch the Compressor’s web viewer automatically.
DW-CP16
DW-CP16 Compressor™ User Manual
Digital Watchdog® 22 www.digital-watchdog.com
You may also discover and access your Compressor by using the IP Utility tool. The IP Utility is a
light software tool that can discover the encoders, show their basic information such as IP and
MAC addresses, serial numbers, firmware versions, etc., and allows quick configuration of
multiple devices simultaneously.
The IP Utility can be downloaded for free from http://www.digital-watchdog.com
With just one click, you can launch the IP Utility:
You can locate the encoder model in the list. Click on the IP address to automatically launch the
Compressor’s web viewer.
Compressor’s Default IP Address:
If there is no DHCP server in the given network, you may have to assign the IP addresses to the
encoder manually.
When the encoder is plugged into network and it does not detect any DHCP services, it will
automatically assign itself a default IP address:
DW-CP16 Compressor™ User Manual
Digital Watchdog® 23 www.digital-watchdog.com
192.168.0.100
The default port number would be 80. In order to access that encoder, the IP address of the PC
has to be configured to match the network segment of the encoder.
Manually adjust the IP address of the PC:
1 2 3
4
DW-CP16 Compressor™ User Manual
Digital Watchdog® 24 www.digital-watchdog.com
DW-CP16 Compressor™ User Manual
Digital Watchdog® 25 www.digital-watchdog.com
Manually adjust the IP addresses of multiple encoders:
If there are more than 1 encoder in the same local area network and there is no DHCP server, all
of the encoders would then have the initial IP address of 192.168.0.100. The easiest way to assign
encoders the IP addresses is by using the IP Utility:
With the procedure shown above, all the encoders will have unique IP addresses, starting from
192.168.0.101. In case there are 20 encoders selected, the last one of the encoders would have
the IP 192.168.0.120.
Press the “Refresh” button of the IP Utility to see the list of encoders with their new IP addresses.
Please note that it is also possible to change the IP addresses manually by using the Web browser,
plugging in one encoder at a time, and changing its IP address using the Web browser.
