8.6 Validation of the output signals transmission
If so desired, transmission of the HF8 output signals can be validated by using the simulator function. The
HW4 software is required to enable and configure this function. When this function is enabled the HF8
generates fixed digital and analog signals as specified by the user. For instructions see document

9 Firmware updates
Firmware updates will be available on the ROTRONIC website for downloading. Firmware files are given a
name that shows both to which device the file applies and the version number of the firmware. All firmware
files have the extension HEX. Procedure for updating the firmware:
• Use cable AC3006 to connect the service port of the HF8 to a USB port of a PC with the ROTRONIC
HW4 software installed. Note that the ROTRONIC USB driver must be installed on the PC as
explained in the HW4 manual E-M-HW4v3-Main. In the case of a model with digital interface, a
connection with the PC can be established via the USB (ROTRONIC USB driver), Ethernet or RS-
485 interface.
• Copy the firmware update file from the ROTRONIC website to the PC.
• Start HW4 software on the PC and search for the HF8 (HW4 Main Menu Bar > Devices and Groups
> Search for USB Masters).
• After finding the HF8, expand the device tree to see the HF8 functions. Select Device Manager. In
the Device Manager menu bar select Tools > Firmware Update. For instructions see document
