1700 Series Wafer Reader Appendix D: Using the I/O Expansion Module
111
6 From the drop-down list beside the OK button, select I/O Expansion Module. The
Discrete Output dialog will be automatically reconfigured to correspond to the I/O
Expansion Module, as shown in Figure D-0-4.
NOTE When an existing .JOB file containing a WriteDiscrete function is loaded on an In-Sight 1700
reader to which the I/O Expansion Module has just been added, the Start Bit and Number of
Bits parameters in WriteDiscrete must be changed to reflect the new configuration of the I/O
lines. For example, the physical output lines 4 and 5 become lines 10 and 11 (Green and
Yellow LEDs) when the I/O Expansion Module is enabled.

7 Select OK to copy the new settings to the 1700 reader’s flash RAM.
NOTE An error message will appear if the I/O Expansion Module is not attached to the 1700 reader,
and the Discrete Output dialog will return to its default configuration. Verify that the I/O
Expansion Module is connected as described in Section 2.1.4, then repeat steps 1 – 7 as
described above.
Alternatively, the sensor can be configured to use the I/O Expansion Module by opening
the Discrete Input dialog and following steps 6 and 7, as described above.
Once the I/O Expansion Module is selected in either the Discrete Input or Discrete Output
dialogs, it is automatically enabled for both inputs and outputs, and hardware
handshaking may be used in serial communications.
Refer to the In-Sight Guide & Reference HTML Help file installed with the In-Sight PC
Host for details on using the Discrete and Serial Input/Output functions in the In-Sight
spreadsheet.
