External RAM Data Addresses
The External RAM Data Addresses are used to access data values,
reference values, and other values. The following list covers the most
commonly used addresses. In addition, there are several notes that
caution the user and must be followed.
NAME ADDRESS DATA PARAMETERS
*Memory
Reset
0C8 1 Byte Write a 00 to address
plus a "P" command
to reset system.
*USE THIS ADDRESS WITH CAUTION: Writing to this address
will force system reset, and the unit will clear all memory locations.
Calibration and data will be lost. Make sure that a system reset is
what is desired.
ORTHO
UV
DEN Data 0C0,0C1 0C2,0C3 2 Bytes Least significant bit
REF 0D0,0D1 0D2,0D3 (LSB) = .001D
+DOT Data 0E8,0E9 0EA,0EB LSB = .1%
Ref 0F8,0F9 0FA,0FB
-DOT Data* 118,119 11A,11B LSB = .1%
Ref* 120m121 122m123
*-DOT values are subtracted from 100%
ex. Display = 99% -DOT Data = 1%
Values are in
hexadecimal.
