mA Pointer
Used to point at different variables that should represent the analog output. This variable enables the
unit to represent any variable available in the RAM space on the analog output. To be able to take full
advantage of this variable, some in‐depth study is needed for the different locations of common
variables. Default value is the instantaneous rate (28).
USED IN: Monitor mode
RELATED VARIABLES: mA shifter, mA offset, mA gain
HEX ADDRESS: 0095 HEX ‐‐‐‐> SAME ADDRESS AS IN EMO‐2000
BYTES: 2 Bytes DEFAULT: 28
ASC form COMMAND: reading = 131; writing = 531; E and N return an integer number.
mA Shifter
The shifter is necessary to scale some of the variables that are in different byte lengths. It also provides a
divider for variables that are very big. The shifter is really a two part variable as follows:
 The upper nibble represents the amount of bytes that the variable has.
 The lower nibble represents the divider.
 The upper nibble should be a number 1 to 4.
 The lower nibble should be a variable 0 to 12.
 By OR’ing the two nibbles, the result is the shifter.
 The default value is OR’ed from the two following nibbles:
 HIGH nibble 4h
 LOW nibble Ch
By OR'ing 40H | 0Ch ===> 4Ch=76d. The default value is 76d.
USED IN: Monitor mode
RELATED VARIABLES: mA pointer, mA offset, mA gain
HEX ADDRESS: 0097 HEX ‐‐‐‐> SAME ADDRESS AS IN EMO‐2000
BYTES: 2 Bytes DEFAULT: 76
ASC form COMMAND: reading = 133; writing = 533; E and N return an integer number.
A listing of programmable variables appears on page 46.
