Envision Peripherals NV3128 manual Settings, RE-INITIALIZE BIT/MULTIDROP Enable s7

Page 32

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.
