connector on the rear panel provides the interface for these inputs and
outputs.
The 25-pin terminal board assembly is included with the optional I/O
expansion board. Refer to "Terminal Board PCB Assemblies" on page 2-5
for information on attaching the cable to the connector board. For
associated part numbers, refer to "External Device Connection
Components" on page 7-5.
The optional terminal block and cable kits provide a convenient way to
connect devices to the instrument. These kits break out the signals on the
