BenchPro™ 4100 Firmware Upgrades

The new firmware (version 2.0) adds a manual PAUSE function during a run. This can be used to pause the instrument during a run so that individual steps in the protocol may be performed manually. For example, the pause function can be used to perform an off-line primary antibody incubation step that uses a reduced amount of antibody than is consumed in the automatic protocol. Note that it is not possible to remove and/or replace the card during a manual pause .

The new firmware also specifies that the liquid flow of an aborted run is directed to waste, rather than to all the outlets.

Requires USB flash drive for firmware installation.


Download the firmware to the USB flash drive. With the power off, insert the USB flash drive into the BenchPro™ 4100, and then turn the power on. The BenchPro™ 4100 will automatically recognize the firmware file. Follow the directions on the BenchPro™ 4100 screen.
