Opening and Closing Channels

Example: Closing and opening matrix channels (two-wire mode) The following commands close and open channels 311 and 312 through 315 of the L4433A in 2- wire mode. 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.

ROUTe:OPEN (@1311,1312:1315)

Example: Closing and opening matrix channels (L4433A in one-wire mode) The following commands close and open channels 311 and 312 through 315 of the L4433A in 1- wire mode. 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 the L4433A in 1- wire mode.

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 114 for channel number
	derivation.

Example: Closing and opening Analog Bus relays The following command

connects the analog buses to Matrix 2 (2- wire mode).

ROUTe:CLOSe (@1921,1922,1923,1924)

ROUTe:OPEN (@1921,1922,1923,1924)

NOTE	For 2-wire mode, only Matrix 2 connects to the the analog buses. In
	1-wire mode, only Matrix 3 and Matrix 4 connect to the analog
	buses.

The analog bus relays (numbered 1921, 1922, 1923, 1924) on the L4433A 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 1504 and channel 1708. In addition, this command closes Analog Bus relay 1921. Note that although the specified range of channels includes the other Analog Bus relays, they are ignored and are not closed by this command.
