Real-Time Clock (RTC)
•
When enabled via the Real-Time Clock Setup in the Settings WEB
page, WEBster outputs the date and time to its RS232 port once each
second. Depending on how the serial port is configured in the Serial
Port Setup WEB Page, this can be formatted in simple ASCII or in
Alcorn McBride Show Control message format.
Alcorn McBride Show Control RTC Message Format
In the
following
table, and
throughout
this manual,,
the prefix
“0x” refers to
the

representation
of the number.
When enabled via the Real-Time Clock Setup in the Settings WEB
page or the DIP switch, WEBster outputs the date and time to its
RS232 port in the form of SetVarEQ messages. When connected to
an Alcorn McBride show controller, sequences can be designed to
use these variables to perform various tasks based on time.
The output occurs once each second, and variables are set to the
hexadecimal value of the corresponding date/time parameter. The
table below shows which variables relate to which date/time
parameter. The example shown is for the date 1/15/59 and time
9:26:05 AM.
