Getting Started with DTrol

Requirements, network setup, and app setup for your NAD processor or receiver.

Requirements

An active WiFi connection is required, and your controlled device(s) must be reachable on the same network.

There are two ways your controlled device can be reachable on your network:

if your processor/receiver has an Ethernet port, you can use that to connect your proc/receiver; or
by using a device that bridges your network to the RS-232 port on the back of your proc/receiver — like a Global Caché iTach.

DTrol refers to this connection — of either type — as a "Server".

Supported processors and receivers

DTrol is designed to work on the following NAD processors and receivers:

NAD T175
NAD T175 HD
NAD T765
NAD T775
NAD T785
NAD T187
NAD T777
NAD M15
NAD M15 HD
NAD T755 (may generate a warning because it only has two zones)

Network Setup

A static IP address for your iTach or your proc/receiver is required to use DTrol — a static IP address can be configured on your iTach, processor, or receiver, and/or via your router. This is critical: if the IP address of your controlled device changes, you will have to delete your Zones and set up the Server again (or get the device back to its original IP address). Enforcing the use of a static IP address keeps DTrol fast and stable.

Ethernet — use the static IP address of the proc/receiver and port 23.
Global Caché iTach — use the static IP address of the device, and generally you will use port 4999.

For a Global Caché iTach, your serial settings must be set as follows:

Baud Rate: 115200 bps
Flow Control: None
Stop Bits: 1
Parity: None
Data Bits: 8

Setting a static IP address: it is your network to configure — you can configure a static IP within your router. Or, on many home networks, homeowners will just take the last three digits of a typical DHCP-assigned IP address on the network, add ~50 to the number, and set that as the IP address on the device itself (turn off DHCP). For example, if such a homeowner was seeing addresses internal to their home network that look like 10.0.1.8 or 192.168.0.112, they would then turn off DHCP on the device and give it a static address of 10.0.1.60 or 192.168.0.160.

Application Setup

Once your processor or receiver is connected to your network, touch the '+' button in DTrol to add your proc/receiver(s) as a DTrol Server. You will need to know your static IP address and port. DTrol will search for and scan your proc/receiver to set up your Zones and Sources. After adding your device as a Server, you can make changes to Zone names, Source names, and other details in DTrol via Settings. Changes to names are reflected only in DTrol, not on your proc/receiver.

Settings

You can make changes to names and other details via the Settings within the app.

Your Data

DTrol does not collect, use, save, or have access to any personal information. Everything you enter — such as Server IP addresses — is stored locally on your device. See our Privacy Policy for details.
