Breakpoint Output Terminal Block
For breakpoint output wiring, the UMI-Flex4 has a 6-position terminal
block. This terminal block also provides access to the four breakpoint
outputs as well as the isolated voltage input. See Figure 41 for more
information on breakpoint output and isolated voltage input wiring.

The opto-couplers on the FlexMotion board can be powered either from an
external source or from the FlexMotion board itself. If you want to use an
external source for the isolated voltage, you must configure the FlexMotion
board for this setting prior to connecting the external source.
Caution Failure to configure the board properly for an external power source may damage
your UMI and FlexMotion board.
Power Input Terminal Block
The UMI-Flex4 has a 4-position terminal block for wiring power to the
unit. Refer to Figure 33 to help you locate the power input terminal block
on your UMI-Flex4 accessory. Figure 42 shows the 4-position terminal
block pinout.

Note To properly operate your UMI-Flex4 accessory, you must supply a +5 V source to
the power input terminal block.
Note The +5 V power is redistributed to other terminal blocks as an output power source.
