Removing/Replacing Terminating Resistors
When using your unit with more than one other device, you must
decide where your unit is to reside on the control bus. Depending
on its location on the bus, you may need to remove resistor R400.
■
If your unit will reside at the end of the bus, leave R400 in
place
■
If your unit will reside mid-bus, remove R400
■
R401 should not be installed in either case
