RS-232 Controlled Devices (Regardless of System Type)
By adding an SC-4 Serial Controller or SS1 System Station to any system
using VIA! Touch Panels, powerful RS-232 control becomes possible for
a wide assortment of devices such as security systems, lighting systems,
HVAC, spa control, A/V gear, etc. Use the appropriate PVIA Wall Plate or
Precision Panel for the number of VIA! Touch Panels in the system and the
system type. When installing an SC-4/SS1 in an S12 or S8 system, a PVIA
Wall Plate is not needed; the SPP or PS12 Precision Panel has all necessary
provisions.
