set all positions of S1 and S2 to OFF. If you would like to operate at a data rate other
than those shown here, call Black Box. If your SME can support your desired data rate, technical
support personnel can help you determine how to set these switches. If standard SMEs can’t
support your data rate, Black Box might be able to give you a quote on a custom unit.
