The PartnerTech SG-15+ is an entry level, small and attractive price checker with latest technology. Interfacing is either through Wireless RF or hard wired Ethernet. The bright display has, depending on the font set, 3 or 5 lines and can display up to 20 characters per line. Size and Design (three colors) help to install the SG-15+ in different environments. This flexibility of installation is enhanced by the optional Power-over-Ethernet.
