Firmware
Topology group：Up to 15 pumps in one group, support group control and individually addressed
Upgrade firmware online："One Click"  by customer  through PC Utility
Homing Algorithm：Plunger home position is identified by motor stall, which will reduce the dead volume of the system
Halt function：For better interactive control, "h " command is used to halt execution of the command string during plunger movement. To resume execution with "R" or "r" command
Microstep mode：Set microstep mode for smoother motion with 48000 microsteps per stroke, 1/8 microstepping or 1/16 microstepping
Programmable parameter：Programmable ramps, cut-off velocity, plunger speeds, backlash compensation,  programmable work-flow command set , delays and loops, terminate moves, diagnostics, absolute and relative positions

Environmental
Operating temperature：Recommended: 15℃-40℃ ，use low temperature syringe for low temperature application
Operating Humidity：＜80% RH,  no condensation
Storage temperature： -20℃-65℃
Storage Humidity：＜80% RH, no condensation
