Figure 4.16 68 pin type 16-bit SCSI interface connector
b.Power supply connector
Figure 4.17 shows the shape and the terminal arrangement of the output connector of DC power supply.
Figure 4.17 Power supply connector (68 pin type 16-bit SCSI)
(3)SG terminal
The IDD is not provided with an SG terminal (fasten tab) for DC grounding. Therefore, when connecting SG and FG in the system, use the +5 VDC RETURN (ground) inside the power supply connector as the SG on the power supply side.
(4)Connector for external operator panel
•Connector for
CN1 provides connector for the external operator panel other than the SCSI bus as shown in Figure 4.18. Also, a connector for the external operator panel are provided on the IDD as shown in Figure 4.19. This allows connection of an external LED on the front panel, and an SCSI ID setting switch. For the recommended circuit of the external operator panel, see Subsection 4.3.4.
