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) Lift up the upper case.

1) Release the screw.

NOTE: There are 6 hooks at the bottom side of upper case. Please be careful.

2) Mount the I/O PB-12 to the mother boards slot connector as shown in the following.

Ensure that the red dot line mark is No.1 pin.

2) The standard setting for SW1(INT1), SW2(INT2) and SW3(PORT) are as follows:

SW1: Standard setting is IRQ10. SW2: Standard setting is IRQ11. SW3: Standard setting is 1E0H.

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.

1) BPS speed: 1,200bps, 2,400bps, 4,800bps, 9,600bps, 19,200bps

2) Connection: T branch

3) Terminator: Open

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.

6) Dip switch
