4.5.2 Controlling multiple Kaleido-K2s using RS-422 with a Kaleido-RCP
Using the RS-422 communication port also allows up to 99 daisy-chained Kaleido-K2 frames to be controlled using
only one Kaleido-RCP. With a multi-drop cable, this port directs communication between a series of Kaleido-K2
frames and the Kaleido-RCP. Figure 4.5.1.2 illustrates cabling between the Kaleido-K2s and Kaleido-RCP.

Figure 4.5.1.2 Kaleido-K2/Kaleido-RCP interconnection for cascading multiple frames
As indicated in figure above, a 120
Ω termination resistor must be installed on the cable connector on the last
Kaleido-K2 frame. In a point-to-point connection, it must be installed on the receiver (refer to figure 4.5.1); for a
more-than-one-Kaleido-K2 frame connection (called a “multi-drop connection”), it must be installed on receiver and
driver. For more details, consult Miranda Application Note #229-99T00-101 (available through Technical Support).
4.5.3 RS-422 Serial ID Assignment
In order to respond to commands, each Kaleido frame must be recognized by the Kaleido-RCP. This can be
accomplished by assigning an identification code to each of the Kaleido-K2 frames. This is similar to assigning
different addresses to buildings on a street.
By default, Kaleido-RCP will send instructions using RS-422 protocol to ID 1. This means that a system comprised
of only one Kaleido-K2 frame will work out of the box as each frame’s default ID is also set to 1. However, for
applications where more than one Kaleido-K2 frame is used, you will need to assign a unique ID number to each of
them. Consult the Kaleido software User’s Manual for details.
