NV3128 RS-422A Machine-Control Routing Switch 2-9

INPUT LENGTH (s8-s5):

Bit 8 (MSB) through bit 5 (LSB) of the B switch section create a four-

bit binary, modulo 32 number that matches the input dimension of the

switch. The length of the partition is the number in the switch times 32.

For the NV3128, the number is 0100 (128). For a 64 port version of

the switch, the number is 0010. No other configuration is valid for a

data switch.

EXAMPLE:

0100 (decimal 128) = an input address range of 128 consecutive

physical addresses.

Note that the settings of this switch are meaningless for the ghost

partition, whose input range shadows the range of the physical partition.

OUTPUT LENGTH (s4-s1):

Bit 4 through Bit 1 of the B switch section create a 4-bit binary, modulo

32 number that configures the output dimension of the partition. As for

the input length setting, the valid values for a data switch are 0100

(decimal 128, NV3128 default) and 0010 (decimal 64, small data

switch).

2.2.3 MATRIX CONTROL II JUMPERS (OBSOLETE)

The obsolete Matrix Control II module includes two jumpers that must be set

in order to define the router type. For older systems having these modules, set

the jumpers as follows:

JUMPER SETTINGS MEANING

J701 X-Y Audio type router
