LXT970 Power Up HW Configuration
The LXT970 can be configure for power up by 9 pins 5 of them are connected to the LXT970 through
DS1 (DS1 is a 16 pin contain 8 dip switches) they are the HW configuration pins. The pins MF0 - MF4
can configure the following options:
MF0 enables the autonegotiation, if DS1(1) is OFF it enable the autonegotiation
MF1 selects DTE or Repeater, if DS1(2) is ON it enable the DTE mode.
MF2 selects symbol (5B) or Nibble (4B) if DS1(3) is ON Nibble (4B) is selected.
MF3 enables scrambler operation, if DS1(4) is ON the scrambler operation is enabled.
MF4 select the output possibility options, twisted pair or the fiber optic.

INSTALLATION INSTRUCTIONS
The MPC860TFADSDB should be plugged into the MPC8XXFADS Mother Board. This should be
done when the FADS is disconnected from any power supply. The 860TDB should be placed over
the mother board connectors in a way that the mother board connectors of the 860TDB, PM1 - PM4
match the daughter connectors of the FADS and than pressed gently into position.
The connectors are arranged in a non symmetrical form, so miss-insertion is inhibited.
