The Wireless Telemetry USB Base Station - T24-BSu is required for the configuration of all T24 modules and is greatly simplified by the free T24 Toolkit software for Windows supplied upon purchase. Data can also be captured by the wireless telemetry base station (T24-BSu) from an unlimited number of T24 transmitter modules to provide a wireless data logger. The integral antenna on the T24-BSu offers up to 400 m (1,312 ft) range in an open field site. An industrial base station (T24-BSi) is also available with a different antenna providing up to 800 m (2,600 ft) range. This device also offers RS232 and RS485 interfaces.
