4.6.6.6.1
SDLC STATISTICS
This display shows the number of frames transmitted (TX FRMS), number of frames received (RX FRMS), total
number of frames received with errors (RX ERRS), number of frames received with buffer overrun errors
(OVERRUN), number of frames received with buffer overflow errors (OVERFLW), number of frames with
framing errors (FRAMING), number of very short frames received (V SHORT), number of short frames received
(SHORT), number of long frames received (LONG), number of frames received with the incorrect control byte

FACTORY DIAGNOSTICS
The features and data accessible within the Factory Diagnostics menu and submenus are intended for use by
qualified Test and Technical Support personnel only. Should the need arise, the user will be instructed on the
correct use of these features and data.
4.7
FRONT PANEL LED INDICATORS
The monitor has 77 light emitting diodes (LEDs) that are used to convey
information to the user. These LEDs are color coded to increase viewability
and enhance the intuitiveness of the display. The LEDs are extremely bright to
allow viewing of the front panel indicators in direct sunlight. The front panel
display is updated every 16 milliseconds.
The front panel display is broken up into four logical groups: Field Status,
Power / Type, Transmit / Receive, and Fault.
4.7.1
FIELD STATUS INDICATORS
There are 60 field status indicators, one for each field input defined by the TS 2
specification for Type 16 and Type 12. The display is logically organized into
four columns and sixteen rows. The columns are labeled
R
for Red,
Y
for
Yellow,
G
for Green, and
W
for Walk. The rows are numbered from
1
to
16
,
corresponding to the channel numbers for Type 16 and Type 12.
The indicator for a field input will be on if the RMS voltage over the last 33 milliseconds (two cycles of AC
power) is above the threshold for that type of input. (See Section 3.2 for the voltage levels for each type of input.)
