2.3.2Setup of Master I/O Box
Note that the DIP switch settings of the Master I/O Box differ depending on whether the
system configuration is consisted of only single Master I/O Box or of multiple Master I/O Boxes that arefollowed by Satellite I/O Boxes.
Make sure that the POWER switch of the I/O Box is set to OFF. Set the DIP switch at the rear of the unit as follows:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
ON | OFF | OFF | OFF | ON | OFF | OFF | OFF | ON | ON |
Setup for the SCSI ID (DIP switches nos. 6, 7, and 8)
This SCSI ID must be different from that of other I/O Boxes or the PC.
Since generally the SCSI ID of the PC is set to 7, set the SCSI ID of the I/O Box to a number between 0 and 6.
| 6 | 7 | 8 | |
| ID0 | OFF | OFF | OFF |
| ID1 | ON | OFF | OFF |
| ID2 | OFF | ON | OFF |
| ID3 | ON | ON | OFF |
| ID4 | OFF | OFF | ON |
| ID5 | ON | OFF | ON |
| ID6 | OFF | ON | ON |
ID7 | ON | ON | ON |
Setup termination for SCSI interface (no. 9)
Set DIP switch no.9 of the I/O Box, which is the farthest from the PC, to ON.
This setting is the same if only one I/O Box is connected.

Power setup for termination of SCSI interface (no.10)
If the SCSI board in the PC cannot supply power to the SCSI interface, set DIP switch no.10 of the I/O Box, which is the nearest to the PC, to ON. However, DIP switch no. 10 is usually set to OFF, since a general SCSI board can supply power to the SCSI interface.
