Step 4: Set BUS ID Addresses
Up to eight devices can be connected to one control processor. In order for the control processor to be successfully configured,
each device connected to the same control processor must have a unique six-bit, BUS ID, which is set with the DIP switch
assembly on the rear panel of the EBP (see
C
, on page 1). If two or more modules have the same bus ID, address
conflicts may cause one or more of the panels to not be recognized by the IPCP Pro control processor. If there is an address
conflict, the red status LED (
D
) lights steadily (see also
,
on page 9).
Various combinations of the six DIP switches set to On or Off provide 64 addresses:
0
is a reserved eBUS ID and the configurable
eBUS ID range is
1
through
63
(see the table on the two following pages). The section below shows an example of binary to
decimal conversion.

eBUS ID Setup
Add the decimal numbers for each of the DIP switches that are set to On to obtain the address of the device. In figure 5, only DIP
switch #5 is on and the rest are off, which means the address for the device in figure 5 is 0+0+0+0+2+0=2.
NOTES:
•
Any address can be used except address
0
(binary:
000000
), which is reserved as the address of the controller.
•
Switch 1 (on the left) is the highest value (32, the most significant bit) and is labelled
MSB
.
•
Switch 6 (on the right) is the lowest value (1, the least significant bit) and is labelled
LSB
.

The factory default address for the EBP 108 RAAP is 25 (BUS ID = 011001). The ID can be changed to any valid value.
The table on the following two pages shows the DIP switch settings for all 64 possible addresses.
Replacing the volume control knob
1.
To remove a knob, firmly grasp the knob and pull it away
from the EBP. There is no need to remove the faceplate.
2.
To replace the knob, align the ridge
inside
the new knob
(figure 4,
1
) with the channel on the knob control (
2
)
and allow the magnet in the knob to snap into place.
