Parking garages are run using a combination of security systems to control access and POS systems to process payments. As these systems are typically located at a distance from any type of network or Internet connection, there are basically two options for implementation. The first, which can be expensive and potentially unreliable is via a completely wireless system. The second is by creating a wired connection between the devices in the system and a nearby network. Using Serial Device Servers is an economical and easy way to make this connection, because it does not require an actual PC workstation at the remote location in order to implement or monitor and service the devices.
