DyNet Text

DyNet Text is a text-based protocol that sends commands to, and receives status responses from, the control network. It is translated to DyNet1 and DyNet2 by the EG (dependent on port settings). DyNet Text can be sent over a serial RS-485 connection or a TCP connection made by a Telnet client.

Issues to consider:
  • Presently, DyNet Text does not have an EEPROM section. This means that settings cannot be saved between sessions.

  • DyNet1 uses separate time and date messages. DyNet2 uses a combined time and date message.

  • Commands that have device codes and box numbers as arguments must either have both or neither. You cannot supply a device code without a box number.

Syntax

DyNet Text commands use a single keyword command followed by a number of arguments. Commands and arguments are not case sensitive.

Preset 1 2 5000 (Area 2 fade to preset 1 over 5 seconds)

Most commands have a brief version.

P 1 2 5000

DyNet Text over RS-485 requires an asterisk as a synchronization character. This character is optional when using Telnet.

*P 1 2 5000

Arguments are separated by any number of spaces and/or a single comma.

P 1, 2, 5000

Integer arguments can be written as decimal values or hexadecimal values preceded by "0x". Temperature values can be written with or without a decimal point and have two decimal places of precision.

P 1, 2, 0x1388 (Area 2 fade to preset 1 over 5 seconds)

Whenever a command uses an Area, Fade time, Join, or Channel Level, that value becomes the new default value for that argument type. There are two edge cases to this rule:

  • The AreaMinMax command does not set the default value for Areas.

  • The JoinLevel command sets the default Join value to its third argument.

Telnet access

Your PC can connect to the EG via Telnet, using a serial terminal program such as PuTTY (shown here) or HyperTerminal.

Set up DyNet Text communication from your PC:
  1. Connect your PC to the lighting control network via Ethernet or Wi-Fi.

  2. Open PuTTY.

  3. Enter the EG IP address.

  4. Select the Telnet connection type. (To save the session settings, enter a Saved Sessions name and click the Save button), then click the Open button.

    putty telnet config
  5. The command line window opens and displays "Telnet Connection Established…​"
    Enter DyNet Text commands. The EG acknowledges by echoing the command and "OK".

    putty preset command
  6. When the command is performed, the network sends a reply confirming the action.

    putty network messages

The command line window also shows DyNet Text messages for all network activity seen by the EG, such as light regulation commands in the example below.

Commands

There are three types of DyNet Text messages:

  • Logical messages
    DyNet Text Logical messages act on logical areas. They translate to DyNet1 and 2 logical messages.

  • Physical messages
    DyNet Text Physical messages act on devices. They translate to DyNet1 and 2 physical messages.

  • Configuration messages
    DyNet Text Configuration messages act on the DyNet Text engine. They configure settings and default values for arguments. They do not translate into DyNet1 or 2 messages.

The command tables give the long and short commands as well as the arguments they require. Required arguments are shown in bold. The following table is the argument legend for the command tables.

Network responses

In the current implementation of DyNet Text, all messages that pass through ports in the EG will be checked by the DyNet Text engine. However, not all DyNet messages are understood by the DyNet Text engine. Included messages will be printed to the Telnet console or if not included in DyNet Text, they will be ignored.
