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.

ROUTe:OPEN (@3311,3312:3315)
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: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.

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 163 for channel number
derivation.

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.
