Figure 11. I/O Extender Connections for Guarded Analog Output Calibration.
Within each pair of jumper posts, make sure that you connect
the resistors to the jumper posts nearest the front of the I/O
extender. Do not make any connections to the jumper posts
nearest the I/O chassis backplane — these connect to the
actual field wiring attached to the I/O slot terminals on the I.O
chassis.
Calibration Steps
1. Remove the module to be calibrated from the I/O chassis.
2. Install the I/O extender module into the slot from which
the module was removed.
3. Remove the jumpers (if installed) labeled CH1 through
CH16 from the I/O extender module.
