NV3128 RS-422A Machine-Control Routing Switch 2-8
SETTINGS:
ENABLE (s8):
ON: Partition defined in switchbank is enabled.
OFF: Partition is disabled.
RE-INITIALIZE BIT/MULTIDROP ENABLE (s7):
OFF: On power-up following a shutdown of less than twenty minutes,
the system restores the crosspoint address map stored in battery-
powered RAM. In Bank 2, when bit 7 is OFF, multidrop is disabled
and point to point routing is enabled in the second partition.
ON: On power-up, the system remaps the entire switch with all
outputs connected to the NULL input defined in software. In Bank 2,
when bit 7 is ON multidrop is enabled in a shadow partition.
MONITOR LEVEL BIT (s6):
* Implemented for AES/EBU digital audio versions only. Not used on
NV3128
LEVEL ID (s5 - s1):
Bit 5 (MSB) through bit 1 (LSB) of the A switch section create a 5-
bit binary number that is the logical level of the phsyical partition. This
is the level the controller will use to address the partition.
EXAMPLES:
00001 = level 1
where 0 denotes an OFF bit and 1 denotes an ON bit.
10001 = level 17.
The range is from 0-31. Some control protocols define levels
alphabetically, in which case 0=A and 25=Z.
