Using your Dream Player MC
PRICOM Design
Page 10
The following example shows how to connect switches (or relays) directly to the
Dream Player MC without utilizing the ground isolation features of the opto-isolators.
The convenience 5VDC power supply from the Dream Player is jumped to the opto-
isolator POS terminal to supply the shared LED Anodes. Each Trigger Input can then
be individually connected to the convenience GND pin through any suitable switching
device such as a push-button or relay.

Note: The actual function of each Trigger Input is determined by the settings in the CONFIG
File. More detailed application information is located in Section-4 of this manual.
In the next example we will use an external power supply to enable the opto-isolators
to completely isolate the Dream Player Ground from the controlling device.
Notice that the POS terminal is used, but not the 5V or G terminals. Opto-isolator
power is supplied from the external 4-24VDC Power Supply.
