Connecting a rf portal galaxy 2-20

[Neil a]

Does anyone know how to connect a rf portal to a galaxy 2-20 I’ve tryed but panel doesn’t seem to see it thanks

Which address do you have the rotary dial set to? The G2 only supports two addresses 4 or 5.

So to hijack a thread but are Galaxy detectors one way or two way technology?

 

[Neil a]

Would the rotary dial be the one in the keypad ?
The only thing that’s changed is the main panel .

 

[GalaxyGuy]

No, on the module. The older modules only support 4 or 5 with a jumper anyway. Is the replacement board up to date firmware wise ? V1.56 is the most recent for G2. I'd need to check the version that started supporting the c079 module, as there was an old version that only supported the co77 RF module.

On the rf pcb the jumper is on both pins which I think is 5 and on panel it 1.10

According to the docs, the co79 portal was supported with V2 protocol up to V1.44 on the G2. Alpha and V2 was supported from V1.50 panel firmware. So, you have a co79 module on a V1.10 panel and that should see the portal. What is the portal RS485 LED doing ? Just a slow on off flash and not the single pulsed flash ?

 

[Neil a]

The red light is slow on/off

Okay, so the portal is not being seen by the panel. If the RS485 connection is correct, I would upgrade the panel to V1.56 and try again.
