It is recommended strongly that the DIGIMAX

functions may confuse the user into thinking the box is mal-functioning.

by entering a "1" into parameters #32 through #35 (see pages 21 and 22), but these require
special programming to take advantage of this feature. However, two of the inputs can be
reprogrammed and used without special programming:

When switching from SLAVE to MASTER, the DIGIMAX
at which it is currently running. When switching from MASTER to SLAVE, the DIGIMAX
look to parameter #37 for its setpoint. The default of parameter #37 is 0.0000! If you do not
enter a setpoint in parameter #37 before tryimg to switch from MASTER to SLAVE, the
motor will stop!
When a "3" is entered in parameter #33, the REVERSE input function is disconnected
and TB2 terminal 8 toggles the DIGIMAX
The number in parameter #37 is used for the slave inverse SETPOINT.
ANALOG OUTPUT -- The analog output at TB1 terminals 13(+) and 12(-) will put out
a voltage between 0 and 10VDC from one of four sources (see parameter #28 on page 21).
This output can be scaled for each source with parameters #29 and #30. This analog signal
may be used for anything capable of being driven by 10 milliamps.
ANALOG INPUT -- The analog input may be used to convey an analog voltage to the
comm link, or it may even be used as a dancer by setting the Trim Enable parameter #26.
RATIO RANGING -- You may use parameter #38 to set a minimum ratio. Maximum
ratio is set in parameter #31.
