how to update khd and slave doser?

[windemerejack]

I will not be setting up my khd for another week but I may aswell get it updated ready, so is it just a case of plugging the khd and slave doser in, connect them to the p4 and update firmware for both khd and slave doser?

Yup. One at a time.

does it matter which one first? also would I have to connect the slave doser to the p4, update it and then disconnect it and connect khd to up date or connect slave doser, update it and then connect the khd to the slave doser as it should be for normal operation?
Hope that makes sense

How can I update the khd and slave doser one at a time when they have to be connected together to work?

When updating from the P4 you will disconnect the PAB cable from the KH and leave it on the doser and update the doser. You can only have one device connected via a PAB cable to the P4 when performing firmware updates on the connected device.

Updating a PAB-device is can be done only if you see a new firmware version available for that device within the GHL Control Center firmware folder. There is no need to update the KHD because there is no new FW for it.
