Product Usage Instructions
-
Power Supply Connection
-
Connect the VEXT supply to the board’s VEXT terminal. This supply provides power to the 5V voltage regulator.
-
Connect the global input voltage from an external source to the VIN terminal.
-
Voltage Regulator Configuration
If necessary, configure the voltage regulator to generate 5V logic levels from the VEXT supply. This step is optional and depends on your specific requirements. -
VS Presence LED Configuration
Use the jumper to enable or disable the VS presence LED. This LED indicates the presence of VS supply. -
VIN Source Configuration
Use the jumper to configure the desired VIN source for input signals.
Channel Configuration
- For each channel, connect the individual VIN from an external source to the corresponding input pin terminal.
- There are two alternative sets of terminals available for VOUT. Choose the appropriate set based on your requirements.
- If desired, enable the LED option for each output channel.
Global Status Output Configuration
The STATUS Pin provides a global status output. Use the jumper to enable or
disable the STATUS Pin LED.
FAQ
-
Q: What is the purpose of the voltage regulator?
The voltage regulator is used to generate 5V logic levels for the inputs. -
Q: How do I control each input individually?
For individual control, connect the external source to the respective input terminals. -
Q: How can I enable/disable the LED option for each output channel?
Use the jumper to enable or disable the LED option for each output channel. -
Q: What does the STATUS Pin do?
The STATUS Pin provides a global status output that can be enabled or disabled using the jumper.
