CREST AUDIOæ‹… ETHERNET NEXSYS GATEWAY IS THE EASY WAY TO INCOR- PORATE COMPUTER CONTROL INTO YOUR EXISTING ETHERNET NETWORK.
THE FIGURE BELOW SHOWS A TYPICAL NEXSYS NETWORK USING 2 GATE- WAYS FOR CONTROLLING MORE THAN 32 AMPLIFIERS. THE ETHERNET INTER- FACE SPEED IS 10MBIT AND USES STANDARD CAT5 CABLE. SYSTEMS CAN CONTAIN UP TO 240 GATEWAYS.

THE MAXIMUM NUMBER OF AMPLIFIERS CONNECTED TO ONE NEXSYS BUS IS LIMITED BY THE NEXSYS NETWORKæ‹… ADHERENCE TO THE é„­NSI TIA/ EIA-485 RECOMMENDED STANDARD. A NEXSYS BUS, WHICH CONSISTS OF MULTIPLE AMPS CONNECTED BY A LENGTH OF TWISTED-PAIR CABLE WITH TWO TERMINATING RESISTORS, IS LIMITED BY RS-485 TO A MAXIMUM OF 32 AMPLIFIERS. THE RECOMMENDED TWISTED-PAIR CABLE FOR THIS BUS IS BELDEN 8442. THE MAXIMUM LENGTH OF THIS BUS IS 4000 FEET.

THE GATEWAY CAN TAKE ADVANTAGE OF EXISTING NETWORK CABLING WITH NO NEED TO INSTALL SEPERATE CABLING JUST FOR AMPLIFIER CONTROL. A REAL COST SAVINGS IN LARGE INSTALLATIONS.

PROGRAMMABLE CONTROL I/O

EIGHT PROGRAMMABLE CONTROL PORTS ARE AVAILABLE ON THE GATEWAY. THEY CAN SERVE AS EITHER INPUTS OR OUTPUTS. WHEN CONFIGURED AS AN INPUT, THE GATEWAY CAN SENSE A SWITCH CLOSURE, A VARIABLE DC VOLTAGE, OR A 3-CONTACT POTENTIOMETER. WHEN CONFIGURED AS AN OUTPUT, THE GATE- WAY CAN DRIVE A TTL LEVEL SIGNAL. NEXSYS CONTAINS A UTILITY CALLED EVENT SCHEDULER THAT ALLOWS THE NEXSYS SOFTWARE TO REACT TO AND GENERATE CONTROL FOR EXERNAL DEVICES. THIS UTILITY IS VERY COMPRE- HENSIVE, EASY TO USE, AND EXTREMELY POWERFUL..
