T
he 810-PS2 has a number of enhancements over the previous
810-PS series. It uses new technology in the display to provide
a number of new features:
1. The calibration memory has been changed to a flash memory
device which is much more secure and does not require
power to maintain the memory contents. This should result
in a much more reliable operation, with less chance of a lost
or corrupted calibration.
2. The display can be programmed with a magnet for 8 or 11
bit operation, to work with bars in either 1/3, 1/4, or 1/6 inch
mode. If a sender bar ends up in the wrong mode, then the
display will show bad light and the number of bits received.
The previous displays would either not accept bars in 11 bit
(1/6 inch) mode or could not tell the difference between 8 bit
and 11 bit modes. The mode is stored in the display in the
same secure memory as the calibration.
3. The display has improved diagnostics:
a. If the wrong number of bits are received, then the display
shows “bL:xx” where xx is the number of bits actually
received.
b. If the batteries are getting low, the display will flash “batt”
every few seconds.
c. By connecting together two end pins on the right hand
side of the programming plug (looking at the back of the
display), the display will show a basic inch calibration,
which aids in troubleshooting to determine if the sender
bar or display calibration is at fault.
d. If there is a fault during programming or if the memory is
not functioning correctly, the display shows “Err”.
e. If the memory does not have a valid value for the number
of received bits (either 8 or 11) then the display shows
“Prob”.
f. If the display has no fiber connected and is exposed to
strong light the display will show “Sun” indicating that
sunlight is affecting the display. If a flickering light gets
into the display opto then the display may show either
“Sun” or “bL:xx” depending on the exact nature of the light
getting in.
4. The optical receiver has been improved so it cannot be
overloaded with too much light from the sender bar.
