• r.dot - modulus or wrap around single dot bargraph. This mode of operation allows the
bargraph to wrap around the limits set by the bAr_ and bAr~ functions by dividing
the 7 segment display by the modulus (the modulus is the difference between 0 and bAr~
) and displaying the remainder. For example if bAr_ is set to 0 and bAr~ is set to
10 then in other bargaph modes when the 7 segment display reads a value such as 25 the
bargraph would be stuck at the high limit of its travel since it cannot go beyond 10. In
r.dot mode the display will wrap around at 10 then continue up the bar again and will be
at the midpoint of the bargraph when the 7 segment display shows 25 (as it would for a 7
segment display of 15, 35, etc.). In this example for a 7 segment display of 25 the value of
25 is divided by the modulus value of 10 in this example and the remainder displayed i.e. 10
goes into 25 twice with the remainder of 5 and so a bargaph position of 5 is displayed. This
mode will operate on both vertical and circular bargraph type displays.
5.15 Digital output option mode
Display: dGOP
Range: bcd, b.SCL, bin or bin2
Default Value: bin2
Seen only with the 16 bit digital output option. Refer to the separate “PM4 Panel Meter Optional
Output Addendum” booklet supplied when this option is fitted. Selections available are: bin2
(signed binary) i.e. -32767 to 32767, bin (unsigned binary) i.e. 0 to 65535, b.SCL (scaled binary,
see diG_ and diG~ below), bcd (binary coded decimal) i.e. up to four BCD numbers. .
5.16 Digital output option polarity
Display: dG.OP
Range: AIo or AHi
Default Value: AIo
Seen only with the 16 bit digital output option. Refer to the separate “PM4 Panel Meter Optional
Output Addendum” booklet supplied when this option is fitted. Selections available are: AIo
(active low i.e. logic 1 = 0V output, logic 0 = +V output) or AHi (active high i.e. logic 1 = +V
output, logic 0 = 0V output).
5.17 Digital output option BCD start position
Display: bcd Strt
Range: 0, 1 or 2
Default Value: 0
Seen only with the 16 bit digital output option. Refer to the separate “PM4 Panel Meter Optional
Output Addendum” booklet supplied when this option is fitted. This function affects BCD mode
only and determines the number of digits to skip when outputting from the display. As the output
is 16 bit it can output up to 4 BCD numbers. Select from 0 to number of display digits minus 4.
e.g. for a 6 digit display you may select 0 to 2, if 2 is selected then the four left most digits will
be output, if set to 0 then the four right most digits will be output.
