3.3 Jumper Settings
The jumper positions B1 to B6 are located on the front side of the PB-SIO4. They are
set at the factory as required and should not be changed.
Note!
Jumpers B1 through B6 are zero-Ohm resisters.
Before operating the PB-SIO4 ensure that the jumper settings are
set correctly according to the application. No external VCC may be
applied to the non-optocoupler version, and, correspondingly,
external VCC must be applied to optocoupler versions.
