The TRX-401 is a fully-integrated unit with integral power supply and audio amplifiers. Each TRX-401 unit receives and transmits digital signals to and from the CRLU-201 and other TRX-401 units within the network. Each TRX-401 unit has a unique address in the WAVES network, and is individually software controlled from the base station PC. Up to 15,376 TRX-401 units can be individually addressed in a 16 X 16 X 64 (Zone X Sub-Zone X Unit) structure.
The TRX-401 provides outputs for two channels of wideband amplified audio, two channels of wideband line-level audio, one full-duplex RS-232 data channel (at up to 9.6 kbps), one analog input, one digital input, and two digital I/O data pins. Built-in drivers for specific data devices are available, including LED signs for visual text and graphics displays.
Each TRX-401 unit conducts supervisory built-in self-tests (BIT) that are reported periodically or on-demand to the base station where they are displayed and logged. Changes in supervised variables trigger alert or alarm conditions at the base station PC, and can be further programmed to initiate messaging events throughout the system.
The TRX-401 is housed in a weather-resistant, extruded aluminum enclosure with ABS plastic covers. It mounts easily to an included back plate. The TRX-401 unit is powered from either AC or DC power sources. An optional battery backup unit (UPS- 901) can provide up to five hours of operation. UPS-901 units are stackable to extend backup time.
