The SC-4 System Controller is an RS232 system network interface. It enables as many as 30
VIA! Panels to access up to four RS232 controllable sub-systems including lighting, security,
climate control, and A/V components. Additionally, the SC-4 features one "ELAN RS232 Out" port
which enables serial control of ELAN products without sacrificing one of the DB-9 COMM ports.
ELAN products which may be serially controlled include the HD Series MCU, the SR-1
Sense/Relay Module, and the Z880 Video Controller.
The SC-4 utilizes ELAN VIA!TOOLS software to program the functions of the RS232 controlled
devices in the system. SC-4 compatible versions of VIA!TOOLS (2.0 and later) are available for
download from the ELAN website. VIA!TOOLS v2.0 and later feature 'point and click' RS232 pro-
tocol libraries which enable the installer to assign prewritten serial commands to any button on
the VIA! Panel with a simple mouse click.

!
Four RS232 COMM ports - NOTE: The SC-4 does not support RS232 control of systems
which require hardware "hand-shaking". Systems which operate utilizing "Request to Send"
and "Clear to Send" are NOT compatible with the SC-4.
!
One ELAN RS232 port - enables serial control of ELAN products without sacrificing one
of the DB-9 COMM ports and facilitates RS232 control of the HD MCU, the SR-1
Sense/Relay Module, and the Z880 Video Controller.
!
VIA! Panel network interface - As many as 30 VIA! Panels may be connected to the
SC-4. NOTE: Three PVIA-10 Precision Panels will be required to accommodate the
maximum number of VIA! Panels (30).
Flash memory upgradable - The SC-4's firmware is automatically upgraded when a
!
program is created with a more recent firmware version, and downloaded into the SC-4.
!
Network Status LED - Red = Initializing, Orange = VIA!'s not found, Green = VIAs OK.
!
Transmit / Receive indicators for each COMM port - Indicate the transmission and
reception of RS232 data. Green = Transmit, Red = Receive (data in).
!
"Token" RS232 commands - enable the SC-4 to initiate functions of other manufacturer's
control systems.
