Configuration
After physically installing the unit, you will need to configure it to operate within your system.
Digital control cable
The RS422 digital control signal originates from the remote keypad (KTD-304A or the KTD-304RA) and
connects to the KTR-11 through terminals 1 and 2 of the lower barrier strip on the KTR-11 PC card (
Figure 8
and Figure 9 on page 12.)
Note: The RS-422 cable has polarity. At any location, you must ensure that Digital A corresponds with the Digital A of any
other controllers, receivers, and switchers connected to the system.
