2. Select one of the following for the Pull-up resistor setting:

 Disabled

Suitable, for example, for a high temperature alarm that exceeds the maximum voltage threshold. When the pull-up resistor is disabled, the port state is low and to be triggered it must be pulled high by the externally connected sensor.

 Enabled – Detection of an open circuit as High, or a short to ground as Low.

This is suitable for example, for a pushbutton switch (connecting one terminal of the switch to ground, and the other to the input) or for an alarm closing a circuit that activates a series of actions. When the pull-up resistor is enabled, the port state is high, and to be triggered it must be pulled low by the externally connected sensor.

Protocol 3000

Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or Ethernet ports.

Understanding Protocol 3000

Protocol 3000 commands are a sequence of ASCII letters, structured according to the following.

• Command format:

• Feedback format:

• Command parameters – Multiple parameters must be separated by a comma (,). In

addition, multiple parameters can be grouped as a single parameter using brackets ([ and ]).

• Command chain separator character – Multiple commands can be chained in the same string. Each command is delimited by a pipe character (|).

• Parameters attributes – Parameters may contain multiple attributes. Attributes are indicated with pointy brackets (<…>) and must be separated by a period (.).

The command framing varies according to how you interface with SWT3-41-U-T. The following figure displays how the # command is framed using terminal communication software (such as Hercules):
