Normal Functional Operation

When the StatCast Feature is properly configured
continuously broadcast all enabled record categories and gas levels, at the top of every
gas detector scan loop of the 3500 OI. Ideally, this would be a burst of all gas levels and
rollup status collected during the foregoing cycle; however this depends on how StatCast
is configured. StatCast broadcasts the latest data it contains in the panel (3500 OI)
database. There is a delay between the detector's measurements and when it reaches the
broadcast stream, which will vary depending on configuration of the StatCast feature, the
number of detectors on the loop, etc., however it will at the very least, be a delay of 2
seconds or more.
The StatCast broadcast is present at the RS232 output whenever the primary 3500
OI Operator gas detection summary screens
During those exceptions, broadcasts are paused or stopped. Broadcasts resume when a
primary 3500 OI Operator gas detection summary screen is displayed, or the screen saver
is displayed.
Therefore, as a rule of thumb, if the 3500 OI is not being manually (or remotely)
manipulated, is sitting on the main screen or the screen saver, and the StatCast feature is
properly configured and enabled, then the StatCast broadcast is present at the RS232 port.
The output can be configured as a burst of all status and gas levels measured in
the foregoing gas detection scan loop, or broken up into a sliding-window of a fixed
number of records per scan-loop to maintain gas detection scan loop responsiveness and
performance, absent of increasing StatCast RS232 baud-rate to a suitably high speed. The
sliding window can be configured from as few as one record output per scan, to ALL
records (271) per scan. Regardless of the configuration method, whatever record is output,
that record will contain the most currently known, or up to date value in the 3500
database. See the diagram on the following page to illustrate the two primary methods.
StatCast ONLY broadcasts known devices: it does not broadcast records for
devices that have not been discovered and brought online. Once a device has been
brought online and is in the panel database, it will have a record broadcast whether online
or not until the device is deleted from the database. Therefore, even if ALL records are
chosen for broadcast, ONLY the records related to valid and known devices are broadcast.

Port parameters (baud rate, stop bits, data bits, parity) MUST be saved before they become active-
including first time configuration. In fact, before the timing impact can be properly measured, these
parameters must be saved first, if never previously saved.

Those screens are; Home Zone or main screen, Zone, Bus or Alarm summary screens, Device Selection
screens, Sensor Summary screen, and all Relay Module Screens.
3
Exceptions are; Sensor Configuration Screens (alarm threshold, alarm parameters, relay parameters),
Calibration, Network ID and name change screens, diagnostics, manual override screens, manual device
discovery, 3100 clock set screen, maintenance screens, other 3500 configuration screens, menu screens, etc.
