3.3 MODE CONTROLS
The V1630 has two AES input channels Ain and Bin and two groups of four output channels Aout
and Bout. The mode controls
Aout
and
Bout
allow each of the two groups of four output channels
to receive signal from either the Ain or Bin inputs. The Aout and Bout mode controls are only
effective if the
Rem/Local
switch is set to
Local
. If the
Rem/Local
switch is set to
Rem
, the Aout
and Bout groups have their sourcing controlled by DART. The switches may be changed at any
time and the table below shows the possible combinations:
Aout switch
Bout switch

3.4 DART INTERFACE
The V1630 is a Class 4 DART module with a serial EEPROM for reading and writing card details
through the DARTbus. In addition the unit presents two bytes of status information to the DART system
and the DART system can write one byte of control data to the V1630. Full details of the bit allocations
may be found in document number
