Description
Use these signals to specify one of eight
possible targets. The MDXII
microprocessor uses this information to
keep track of the kilowatt usage for all
eight targets.
Note: An open input defaults to high (15
V); a shorted input is a low (0 V ±
0.5 V).

Use these signals to set the method of
output regulation (see page 5-1). An
open input defaults high to 15 V; a low
input is 0 V ± 0.5 V.
No method of output regulation is
selected if both P REG.D (pin 6) and
I REG.D (pin 5) are low. If you switch
the MDXII unit from local or host mode
to analog mode with this invalid
specification, the message "Invalid
Regulation Mode" displays on the
output display screen, and output power
will not come on. Simply specify a valid
method of regulation from the User port
and clear the message by pressing the
STOP switch or toggling pin 14 (RMT
OFF.D).
