Command Description
MHC=n Motor holding current used when the pump is stationary, n=% of 4A
MRC=n Motor run current used when the pump is running, n=% of 4A
HCDT=n Delay time in milliseconds between cessation of motion and the return to
the current level specified by the MHC variable
MSEL=n Micro stepping resolution, n=2,4,8,16,32,64,128,256
MUNIT=n Conversion factor from motor pulses to user units (µL), n=19 for MSEL=2,
n=304 for MSEL=32. MUNIT=
BLE=n Backlash compensation enable flag, n=1 enable, n=0 disable
BLM=n Backlash mode, n=0 mechanical, n=1 mathematical
BLSH=n Backlash compensation amount, µL
CTR1 Counter of pulses sent to motor
ALL Variable used with GET, PRINT, and IP instruction
ERR Read only flag that indicates whether an error has occurred
ERROR Read only variable that gives the error code of the most recent error
FLAGS Used with GET, PRINT, and IP instruction
IP n Initialize specified parameters to factory default settings, n omitted initializes
ALL, n=ALL, VARS, FLAGS, IOS. You will need to manually update
variables marked with an *.
PGM Keyword to place MicroLynx into program mode
PRINT n Instruction to output variable value to screen
SAVE Instruction to save ALL variables to non-volatile memory
SER Read only variable that contains the serial number of the MicroLynx
VARS Used with GET, PRINT, and IP instruction
VER Read only variable that contains the present MicroLynx firmware version
CP=n Clears the program space on the MicroLynx
EXEC n Execute the program located at address n
LIST n List the program starting at address n
<ESC> Terminate all active operations and running programs
Ctrl-C Terminate all active operations and running programs, forces a partial reset
BAUD=n Sets the baud rate
DN="n" Set the device address for PARTY mode operation
ECHO=n Specifies whether commands will be echoed back over comm line, n=0
Full duplex, n=1 Half duplex, n=2 Only respond to PRINT and LIST commands
PRMT Specifies the character to be used as a prompt character
BSY Flag that indicates whether a program is running
PARTY Enables / disables PARTY mode for multi drop applications
HOST Establish or disble a controller as host in a multi-drop installation.
Host=1 controller is host, Host=0 controller is not host. Host controllers
receive commands on RS-232 and transmit them to other units via RS-485

We recommend that you contact VICI technical support
before changing any of the factory default values. They
are application dependent, and any changes could ad-
versely affect the pump and its performance.
