## B.6. BroadcastTools ACS8.2

Driver Name:

  BroadcastTools ACS8.2

Supported RML Commands:

  GPI Enable ['GE']
  GPI Set ['GI']
  GPO Set ['GO']
  Switch Add ['SA']
  Switch Level ['SL'] [output #1 only]
  Switch Remove ['SR']
  Switch Take ['ST']

Control is done by means of an RS-232C connection to a four pin RJ11 modular jack on the back of the unit (an adapter to a standard DB9 connector is supplied by Broadcast Tools with the unit). Serial port speed on the ACS 8.2 should be set to 9600. Serial port parameters should be set to 9600 baud rate, no parity, 8 data bits, 1 stop bit, no termination.

The ACS 8.2 should be configured to use 'Mix' mode --i.e. DIP switches SW17-5 and SW17-6 should both be 'on', and the unit ID should be '0', with DIP switches SW17-1 and SW17-2 both 'off'.

Operation in 'multidrop' mode is not supported. If you wish to use GPI (referred to as 'PIP', for 'Parallel Input Port' in the Broadcast Tools documentation), then you will also need to be sure that DIP switch SW17-10 is ON.

The ACS 8.2 supports the Switch Level [SL] RML for connections to Output 1. Six different gain levels are supported: 0 dB, -3 dB, -6 dB, -10 dB, -15 dB and -20 dB. For for a specified gain level of greater than or equal to -20, the applied gain will be rounded down to the next supported level. For gain levels of less than -20 dB, the minimum supported gain (-20 dB) will be applied.
