Control Port Window: Digital Inputs

The Digital Inputs are high or low only. They are current driven and will accept +5V or +10V 
inputs (+25VDC max), and are well suited for sensing contact closure (Figure 5.6). They 
switch at approximately +1 VDC. They can be used to control one or more objects with the 
DBC Network Bridge. The Control Port digital inputs can be used to sense logic 'high' or 
'low' signals to control many of the features of the DBC Network Bridge. 

Find the 

Digital Inputs

 section (Figure 5.5) in the 

Control Port

 window. Its features are 

described below.

1. Pin State Indicator

This shows the actual status of the hardware input as it comes into the rear panel connector.

2. Edit Buttons

Pressing one of these buttons opens the Control Port Assignment Dialog box, explained 
later.

3. Pin

This number reflects the physical pin number of the DB37 connector on the rear of the unit.

1. Control Port Object

This field displays the currently selected object or device, such as Digital Input 1 - Pin12.

2. Controls

The control buttons let you select which type of controls you want to display: Any, dB, or log-
ical.

3. Named

You can enter text here to narrow the search for controls.

4. Controls List

This field displays a list of processes that can be applied to the object. Once the desired con-
trol has been found in the Controls List, highlight it and press the Add button (5).
