5. Addressing
Select the proper address by setting address selector
switch SW01 (see the document System Installation,
under "Addressing"). The address must not be 00
nor the same as any other 900 unit address.
6. Selection of A or B Bus
A bus is normally used (always used in CTS 900).
To use B bus: remove the 0 ohm resistors R01, R02
from the PC board and solder together jumper points
S01 and S02. (See drawing above.)
7. Wiring Runs
The plastic partition (shaded in the drawing) is scored
to facilitate breaking at convenient intervals.

screw connector J03. (See the document "System
Installation", under "Supply Voltage").
2. Connect modular bus cabling to J01 and J02
(1 in drawing at below left),
and / or
A or B bus to J03 screw 5 and 6
(dwg below and 2 in drawing at left).
Use only A bus in CTS 900 !
