which devicet hey are working with. Since all MPSD commands are buffered,
Device0 is responsible for echoing MPSD commands to the console.
:unassign - cancels MPSD mode for all connected devices
:unassign
Thiscommand removes all connected devices from MPSD mode. Device 0
thencommunicates with the console as a stand-alone device.

Selects a particular device to communicate with the console. Other devices
whichdo not match the device number or device name are deselected. If a non-
validnumber or name is entered, the console cannot receive any responses to
commandsor queries because none of the devices is selected. Entering the
:select commandwith a valid argument re-establi shesco mmunication with
theconsole.
Ifa non-MPSD device is connected to the end of the chain and a non-valid
devicenumber or name is entered, the non-MPSD device is selected. However,
if theintent is to control a non-MPSD device in a chain of devices, use the
:auxdevice command.
:auxdevice - select a non-MPSD device
:auxdevice
Tosend serial commands to a non-MPSD device installed at the end of the
MPSDchain, use the :auxdevice command.If no such device is
connected,the console will not receive any response. When the non-MPSD
deviceis s elected, an error message in response to the initial MPSD command
maybe shown on the console because the non-MPSD device cannot recognize
it.
Tore-establish communication with the MPSDde vices, use either the
:assign or :select command.
