1. IN/ON LINE BOARD I/O PB-12
1-1. To mount the I/O pb-12 in the P/C unit
1) To open upper case of the P/C unit (In case using SA-3000 as a P/C unit), release the
one screw of the back side and lift the upper cas up from the CPU unit.
2) Mount the I/O PB-12 to the mother boards slot connector as shown in the following.
[Hardware Configuration]
1) Release the screw.
2) Lift up the upper case.
NOTE: There are 6 hooks at the
bottom side of upper case. Please
be careful.

2) Connection: Multi drop
3) Terminator: 100 Ω
4) We recommend that PC is a terminal set.
5) If PC is not the terminal set, FG(PC side) should not connect with cable ground.
Then to make 10 cm of cable which is non-terminal resist.

4) We recommend that PC is a terminal set.
5) If PC is not the terminal set, FG(PC side) should not connect with cable ground.
Then to make a 10 cm of non-terminal resistor and to connect it in this case.
