One last thing - does anyone have an idea of what the
"SW" and "OP" jacks
at the bottom of the front panel are,
Here is a quotes from a GP-10 brochure:
"The OP termination is the system's mode control bus.
For centralized integrator mode operation, the SW
switch control is patched to the OP bus."
My take on this is that if you are not controlling
the operation mode from a digital computer or other
external device, then you need to jumper OP to SW
for each integrator in order to control the mode
from the front panel buttons.
IC = Initial
Condition mode
HD = Hold mode
OP = Operate mode
RO = Repetitive Operation mode
and how to use the multipliers? I
can't quite seem to get them to 'multiply'...
Here is a quotes from a MICROPATCH brochure:
"Two multiplier networks may be arranged as
multipliers, dividers, squarers, or square root
extractors of input variables. Two attenuator-switch
networks are needed to electronically program a
multiplier or divider. One output is patched to the
"X" terminal; the other is patched to the "Y" terminal.
When the network is patched as an input to an
operational amplifier that has a resistor as the
feedback, the amplifier's output is the product
of the input variables. When the network is
patched as the amplifier's feedback, the amplifier
output is the quotient of the two input variables."
