Changing the Subnet mash of ESP


I got stuck in one of the project where client was using the network with a subnet mask of '/26' i.e. and wanted to have ESP on the same network.

But ESP works on a fixed subnet of '/24' and we had atough time convincing the customer.

Has anyone ever faced such situation??

Is there a solution to it??

Re: Changing the Subnet mash of ESP

Hi Navin,

Unfortunately, the ControlSpace architecture was only ever designed to work with /24 subnets which is usually not an issue becasue it tends to be used on an isolated network (or with other AV devices). There are two possible workarounds depending on the requirement to have it on the client network.

1) If the requirement is to access the ESP via ControlSpace Designer from a PC on the client network, then a possible workaround is to have a basic PC local to the ESP running Designer and then use remote desktop/VNC applications to remotely link to that PC from the client network.

2) Alternatively if the requirement is to be able to control the ESP using serial-over-ethernet then rather than connecting directing to the ESP via the LAN connection you could use a serial device server linked to the ESP's serial port and then connect the device server to the client network.

Hope this helps

Best regards

Re: Changing the Subnet mash of ESP

The remote desktop approach does work. I have personally installed a system like this with a customer who wanted to have remote access to the system. Even through VPN connection I was able to control the system.
