ST-888 ANI Decoder/Display Unit
ST-888 ANI Decoder/Display Unit is a key component of the Selectone
Mobile call� ANI (Automatic Number Identification) System, which
provides instant identification of a transmitting mobile or station
unit in a two way radio system.
Applications include remote status monitoring and control systems, taxi systems, police and public safety, courier services, and other fleet dispatch systems where positive identification of the mobile unit is desired to reduce channel time, to identify system abusers, or to provide a permanent record of fleet activity. The popular Selectone Mobile call ANI System is in daily use throughout the world in over 3,000 fleets with over 75,000 mobile and portable radios.
The ST-888 Decoder/Display is typically connected to the base radio at the dispatcher's location to provide a visual display of the identity of each transmitting mobile unit. The ST-888 is compatible with the industry-standard DTMF (Touch-Tone�) signaling format. Therefore, each mobile unit must have a DTMF ANI signaling option, or be equipped with the Selectone ST-804A ANI/ENI Encoder, or similar ANI encoder module.
The ST-888 is an attractive desk top console measuring 8.0" W x 4.3" D x 1.7" H and operates on 13.6 VDC or 117 VAC with wall mount adapter. The ST-888 includes a real-time clock and calendar, eight code memory recall stack, Centronics parallel port for printer interface, and a RS-232C serial port for interface to a terminal, serial printer, or computer.
