INHOUSE:PSEUDO

The INHOUSE:PSEUDO command controls the use of the register interface. Pseudo set true specifies that pseudo register interface should be used. Pseudo set false specifies that the hardware register interface should be used. The value set takes effect next time the unit powers up [does not take effect immediately]. The pseudo register interface allows the use of REG_ENABLE and CLEAR_LATCH capability from the registers. Although the hardware register interface is much faster than the pseudo register interface, it lacks the above two features. It is important to note that when the module is shipped from the factory, pseudo is set to 1. It is also important to note that all letters of the command must be provided as there is no short form for this command.

INHOUSE:PSEUDO <boolean>	Where <boolean> is 0 OFF 1 ON.

EXAMPLES
INHOUSE:PSEUDO 1	Sets the pseudo register interface ON. (The
	unit must be powered for the change to take
	effect.)
INHOUSE:PSEUDO?	Returns 1 which states that the register
1	interface is set to pseudo.
