Hi, I have a Flex panel with 2 keypads wired to the RS485 Bus. I have fitted 680 ohm resistors on each keypad and removed the jumper at the bus. I want to add C079-2 RF Module so that would be a third set of wires coming from the bus. Do I need to add another EOL resistor?
Thanks for your help.

No, don't add another resistor. Depending on the cable length to the new RF portal you will be creating a star based network and that isn't supported. In reality, with devices usually within 10 to 20 metres away, the resilient rs485 bus will have no issues.
