2.4.7 External Power Connector
Due to the significant power consumption of the PC CPU (up to 2A @ 5VDC), the module has been
designed to accept external power. A three-position terminal strip is located on the bottom of the module
and may be used to connect an external 5VDC power supply.
Note: For optimum performance,
Horner APG recommends using an external power supply (rated at 3A or more @ 5VDC, low
ripple) with the PC CPU.
The module overlay is labeled to indicate the proper polarity of the connection.
Before external power can be provided at these terminals, a jumper must be removed within the PC CPU
Module Assembly (note Figure 2.5 below).
Equipment damage will result if power is provided to the External Power
Connector without the removal of this jumper.
