- Page 2 The switch matrix utilizes monolithic, CMOS matrix IC's to achieve minimal crosstalk. The AS8x8 can be manually controlled using the front panel controls or remotely controlled via a standard, asynchronous RS232 Serial Interface. The eight audio inputs are fully buffered.
- Page 3 Interface common to most all personal computers. Refer to the Appendix section, for detailed information on the serial interface connections. For systems employing a single AS8x8 unit, the serial cable is connected to the rear panel RJ11 connector labeled HOST. For systems using multiple AS8x8's, the systems are "daisy-chained"...

Page 8: Command Description
The unit switches immediately after receiving the carriage return. R (READ) This command causes the AS8x8 to transmit the current settings of all 8 audio outputs to the host computer. No carriage return is necessary. L (LOCK) When received , this command locks the current audio setting to prevent changes. - Page 9 Mode 4. You must use both Channel 3 and Channel 4 to set the ID address. The range of ID address supported with the AS8x8 is 01 to 99. As you can see, ideally, nearly one hundred units can be controlled in this manor.
- Page 10 ID address 01). A carriage return is required after this command is entered. SP (Sleep) This command is used to stop an AS8x8 from acting upon commands that may be sent to a different ID addressed AS8x8 connected to the same RS232 line.
