The TST-902 primarily communicates via Crestron ER instead of Wi-Fi and wireless communication is enabled via the Crestron Extended Range RF Wireless Gateway (CEN-ERFGW-POE) for ultra-dependable wireless performance up to 200 feet indoors.
While the TST-902 can be used to control communications using ER wireless alone, you can use ER and Wi-Fi together (dual-mode) to integrate streaming video from IP cameras or for web browsing.
Crestron says the TST-902 incorporates new fast-charging Lithium ion battery technology that makes it possible to keep the device docked indefinitely without killing the battery. And, to help extend battery life, the Instant-Waking feature allows the TST-902 to go to sleep within seconds of putting it down. But you’ll never have to wait for the screen to wake up — with Instant Waking the TST-902 is always ready to go. If necessary, the TST-902’s battery is field replaceable.
