Figure 2–4. Atmospheric Dump Bypass Plumbing
Several components are available for connecting external devices to iSeries
instruments.
These connection options include:
Individual terminal board PCB assemblies
●
Terminal block and cable kits (optional)
●
Individual cables (optional)
●
For detailed information on the optional connection components, refer to
the "Optional Equipment" chapter. For associated part numbers, refer to
the "Servicing" chapter.
The following terminal board PCB assemblies are available for iSeries
instruments:
I/O terminal board PCB assembly, 37 pin (standard)
●
D/O terminal board PCB assembly, 37 pin (standard)
●
25-pin terminal board PCB assembly, (included with optional I/O
●
Expansion Board)
Figure 2–5 shows the recommended method for attaching the cable to the
terminal board using the included tie-down and spacer. Table 2–1
identifies the connector pins and associated signals.
Note All of the I/O available in the instrument are not brought out on this
terminal board, if more I/O is desired, an alternative means of connection
is required.
