POWER
The SSX expansion board can be powered by an external power supply or it can be
powered by the host controller via the SMART-Net
™
port. Connecting an external 12 VDC
power supply to the SSX expansion board will aid in maximizing the overall allowable
cable length.
SS models with I/O, backlight, or CO

require more current. An SSX is recommended for
applications where more than four SSs are installed on the same SMART-Net
™
network or
where the total combined cable length of a SMART-Net
™
network exceeds 50 meters (150
feet).
