The power jumper shunt must be installed correctly to select how the SSX expansion
board will be powered.
TO SET A POWER JUMP-SHUNT FOR AN EXTERNAL POWER SUPPLY
END OF LINE (EOL) TERMINATION
The SMART-Net
™
may be used to extend the EIA-485 network from the host controller to
connected SSs, thereby providing operator workstation access to the network using an X-
Port-2
™
converter. If the EIA-485 network is extended and the SSX is the physical extremity
of the network, the End-of-Line (EOL) termination jumpers (JP2 & JP3) of the SSX should
be installed, and the EOL jumpers/switches on the host controller should not be set.
If the SSX expansion board is not located at the physical extremity of the network, the EOL
jumpers (JP2 & JP3) should be removed.
Whenever an SSX is installed consider using an external power supply to reduce voltage
drop and maximize the overall allowable cable length.
1 Set the power jumper shunt as shown in 22.
