In the External Index (default) position (left), this jumper selects a
user-supplied external INDEX pulse to transfer the counter's value to
output holding registers 1 and 2, or to reload the preset value into the
counter.
In the Internal Period position (right), this jumper selects the internal
sampling time, configured by setup word WY21.04 through .06, to transfer
the counter's value into output holding registers 1 and 2, or to reload the
preset into the counter. The internal sampling time can only be changed in
program mode, as explained in Section 5.7.
