Several components are available for connecting external devices to
i
Series
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
“
External Device Connection Components
” on page
7-6
.
The terminal board PCB assemblies are circuit boards with a D-Sub
connector on one side and a series of screw terminals on the other side.
This assembly provide a convenient mechanism for connecting wires from
a data system to the analyzer’s I/O connectors.
The following terminal board PCB assemblies are available for
i
Series
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
Not all of the I/O available in the instrument is brought out on the
supplied terminal board. If more I/O is desired, an alternative means of
connection is required. See optional “
Terminal Block and Cable Kits
”.
