AHM 16 Connection problems

[Keelan]

hi

I’ve had my ahm 16 for a while now. I am having issues with connection. Each time I try to connect it gives me an unable to connect to ahm 16 timed out. I’ve changed the IP address, used different Pcs and routers as well as Connected the ethernet cable directly to my computer. I’ve also uninstalled and reinstalled the ahm software. both the version on my computer and the ahm unit are the same.

Anything that I am doing wrong

Can you share the network settings (IP address, subnet, gateway) of both your computer and the AHM?

Unit:
IP: 192.168.10.1
Subnet: 255.255.255.0

Computer:
Ip: 192.168.10.100

Subnet: 255.255.255.0

My computer does detect the unit, but it doesn’t connect

If running Windows, check the AHM System Manager is allowed in Windows Defender Firewall for all network types (Domain, Private, Public). If a corporate firewall is installed on your computers, you might have to open specific TCP ports.

I would also check the unit doesn’t have a bad gateway address. You should be able to see current settings in the front panel display. If in doubt, reset the Network settings (jumper switch 6 in the On position at power up), set your computer to 192.168.1.100 and try again.

Provided you have a backup of the Config file, you could also try a hard reset of the current settings (jumper 1 in the On position at power up) in case of any data corruption which is preventing the unit from connecting.

If none of this works, please open a support ticket at support.allen-heath.com and grab a video of the connection timing out.
