Trouble to access external device server

Hi,

At work, we have 2 serial printers that are connected to an external device server (MSS4 Lantronix). This device is connected to a small unmanaged switch, along with a pc1, then to our network in the main switch.

From pc1, everything works fine, printing and pinging the MSS4, and getting anywhere in the network.

From another pc in the office, I can ping pc1, but I can't ping the MSS4. If i remove the unmanaged switch, and connect the MSS4 directly in the main switch, then everything works.

Any idea ?

Thanks,

Guillaume

Is the MSS4 on a different subnet than the rest of the network?

it is on the same vlan. This is the config of the port in the switch :
