We developed an additional power scan module to be mounted on TT Netcoms TT 8000 industrial PDA series, which has been especially designed for warehouse operations. Being charged by a hot-swappable power source, the module is connected and automatically recognized by the PDAs peripheral interface. Depending on its charge condition, the scanner can be supplied by either the PDAs or its own batteries. The scan module is part of the t+t Netcom PDA Family and includes a lot of accessories such as a wall-mountable charging station or a belt holster.
