MM4005 Feature Descriptions Tutorial
Load Communications Mode: CM Command
The MM4005 is equipped with a CM command that can remotely modify
the communications mode, as well as its parameters.
For further details, refer to the description of the CM command (Section 3).
Analog Input/Output: AM, RA, YO, YR Commands
The MM4005 is equipped with four 12-bit analog inputs and four 12-bit ana-
log outputs. These analog input/outputs are reserved for user applications.
The YR command is used to enter a value from an analog port and store it
in a variable buffer.

YR nn
xx [integer] — Analog port number.
1 to 4.
nn
[integer] — Variable number.
1 to 100 (integer variables) and
101 to 120 (float variables).
The YO command lets you send a value to an analog output port.

1 to 4.
nn
[float] — Sent value.
The RA command is used to return the value, entered by a port, to the
computer.
