C. REMOTE OPERATION

A tally can be configured to be controlled by a GPO on a remote Universal Switch
Panel or by a remote event on a GTP-32/DC20. Similar to the Follow GPO
Operation,
the tally will turn ON when the remote GPO is ON and turn OFF when
the remote GPO is OFF.

D. EXTENDED TALLY OPERATION

A tally can be controlled by multiple Combinatorial Logic events on a remote
GTP-32/DC20. Each tally can be controlled by up to 5 different events. Extended
Tally operation requires the USP-ET software, and replaces Alarm Mode when
installed.

Each tally event name starts with ET_, followed by a Name field and a Status
field. The Name field identifies the remote event as a member of a group of
tallies on the USP. When a remote event is received that begins with ET, it
compares the contents of the Status field with the Status field of all configured
ET events within the group, as distinguished by the Name field. If a match is
found, the Tally shows the configured Text/Font/Color for that event. All other
tallies for that group are turned off. If the Status field does not match any
configured events, then the Tally reverts to Off Text/Font/Color, as configured
within the Tally Assignment Page.

VI. ALARM MODE

The Tally Alarm mode of operation allows multiple tally sources― Local GPIs,
Remote USP GPIs, Remote USP GPOs, GTP-32 Events, and DC20 Events― to be
combined into an Alarm Group to control a specific tally (LCD display). Eight Alarm
Groups are supported. Each Alarm Group can contain any combination of tally
sources. The tally sources within a group are prioritized by the user. When
refreshed after a change, the Alarm Assignment Table will display the table in order
of Alarm Group and by Priority within the Alarm Group.

When a tally source turns ON, it is considered alarmed. If the tally source has the
higher priority of alarmed sources within its group, its alarm indicator (ON tally
configuration) will be reflected on the switch LCD display― ON text, ON font, ON
color. The user must press the associated switch (part of LCD display) to clear the
displayed alarm. If the tally source is still ON, the LCD display will continue to show
the tally source’s alarm indicator.

The LCD display will always show the alarm indicator of the higher priority alarmed
tally source that is ON. Alarms from ON tally sources will be prioritized over alarms
from tally sources that have turned OFF. If there are no alarms with ON tally
sources, then the higher priority alarm of the alarms with tally sources that have
turned OFF will be displayed on the LCD. When the alarm is cleared, by pressing
the switch, the new higher priority alarmed tally source will be reflected on the LCD
display. When there is no alarmed tally source in the Alarm Group, the LCD display
will reflect the assigned OFF tally configuration.

When the higher priority alarmed tally source is ON, the LCD display will flash. When
the higher priority alarmed tally source is OFF, the LCD display will stop flashing and
turn on solid. This behavior is the same for LATCH and TOGGLE style GPI tally
sources.
