S128P
INSTALLATION MANUAL
System Expansion
An S128P system can be expanded from eight to thirty-two zones by adding additional units:
1 S128P = 8 zones
2 S128Ps = 16 zones
3 S128Ps = 24 zones
4 S128Ps = 32 zones
Sixty-four zones of video only are also available when linking four S128Ps. The number of distributed audio/video
sources (twelve/sixteen) does not increase with the addition of multiple chassis. The number of local sources, how-
ever, increases by eight with each additional S128P.
Each S128P in the system will have its own UNIT ID, which designates the zones it is controlling:
UNIT 1: Zones 1-8
UNIT 2: Zones 9-16
UNIT 3: Zones 17-24
UNIT4: Zones 25-32
Unit ID dipswitches are found on the S128P's rear panel, and must be properly configured in order for a multi-chas-
sis system to work correctly.
Note: Changes to the Unit ID Dip Switches become active
when the S128P is reset to Factory Default. Each chassis
must be reset in order for changes to take effect. See pg. 75
for Factory Default procedure.

S128P Expansion Kit (S12XK)
Expanding an S128P system requires the use of the S128P Expansion Kit (Model S12XK). One S12XK is needed for
each additional S128P in the system (maximum 3 S12XKs per system).
Each expansion kit includes:
(1) 15-pin male-to-female DSUB cable for the transmission of IR/RS-485 data between chassis
(1) 9-pin male-to-female DSUB cable for the transmission of RS-232 serial data between chassis
(1) 0.5M RCA-to-RCA interconnect cable for routing Page Audio between chassis
(1) 3.5mm mono interconnect cable for routing Page Trigger between chassis
Note: It is essential to use the S12XK Expansion Kit
when connecting multiple S128Ps!
