5 Matrix Switch Modules
Opening and Closing Channels
Example: Closing and opening matrix channels (34931A, 34932A, and 34933A in
two-wire mode)
The following commands close and open channels 311 and
312 through 315 of a 34932A matrix module in 2-wire mode. This module is
in slot 3. The channel number represents the matrix crosspoint of a row (one
digit) and a column (two digits). For example, channel 311 represents
crosspoint at row 3 and column 11 on a 34932A module.

Example: Closing and opening matrix channels (34933A in one-wire mode) The
following commands close and open channels 311 and 312 through 315 of the
34933A module in 1-wire mode. The module is in slot 4. The channel number
represents the matrix and the matrix crosspoint of a row (one digit) and a
column (one digit). For example, channel 311 represents the crosspoint on
matrix 3 at row 1, column 1 on a 34933A module in 1-wire mode.

Example: Closing and opening Analog Bus relays The following command
connects the Analog Buses to Matrix 2 for a module (in 2-wire mode) in
slot 3.
ROUTe:CLOSe (@3921,3922,3923,3924)
ROUTe:OPEN (@3921,3922,3923,3924)
The Analog Bus relays (numbered s921, s922, s923, etc.) on the matrix
modules are ignored if they are included in a range of channels. An error will
be generated if an Analog Bus relay is specified as the first or last channel in
a range of channels. For example, the following command closes all valid
channels between channel 304 and channel 615 (slot 2). In addition, this
command closes Analog Bus relay 911 on the module in slot 1 (Bank 1). Note
that although the specified range of channels includes the other Analog Bus
relays, they are ignored and are not closed by this command.

NOTE
Although the previous two examples show the same channel
numbers, the channels are derived differently as determined by a
module’s configuration mode. See page 139 for channel number
derivation.
NOTE
For matrix modules in 2-wire mode, only Matrix 2 connects to the
the Analog Buses. For the 34933A in 1-wire mode, only Matrix 3 and
Matrix 4 connect to the Analog Buses.
