Do you have network devices that you need to occasionally log in via a console/serial port? For example one wants a backup access to a switch at a remote site? Perle has a solution. In this case the IOLAN SDS32c has 32 ports for serial access.
Here are somethings I discovered.
They have an "Admin" port which I assumed was a serial port to access the box. I could never get any connection, despite trying various serial cables and what not.
The way to set up the box is to power it up, hold the RESET button down for three seconds, once it reboots, launch the software "EasyConfig", it will scan the network looking for Perle devices, once discovered, assign an IP address, then use a web browser to connect to that IP. The default username is "admin" and the password: "superuser"
The models I have also require a CROSS-OVER in the mix. I purchased little adapter/couplers from both MonoPrice and Amazon.
