Connect Digi connect sp

Dear Sirs.

I try to connect a DIGI connect sp to a PC client through the serial port and the ethernet port of the device to the network. the power cable is connected and the red light is ok, but yet can’t find the device through Digi recovery SW. it says “no devices found”.

could you help me with possible causes of this?

Digi Digi Connect SP (-C and -S) are obsolete products.

Device recovery will only work in the local network and you need to disable your firewall (temporary):
