23. y when a host sends a command to change the state of a MicroMSC parameter all the other hosts that have an active connection to that MicroMSC unit will get the same command response This will guarantee that all hosts to be synchronized There are two different kind of unsolicited packets One kind is related to all essential parameters of the MicroMSC The other kind is related to optional status like the peak audio input and output levels and quadrature encoder positions The first kind of unsolicited packets will always be sent whenever the parameter states are changed The second kind will not be sent unless a host has subscribed to the MicroMSC with the SU command The syntax of the SU command is SU lt CR gt lt LF gt to check the current subscription state and SU subscribe lt CR gt lt LF gt to change the subscription state where subscribe is 1 or 0 For example Send SU 1 lt CR gt lt LF gt Revr SU 1 lt CR gt lt LF gt would turn on subscription Once a subscription is turned on the host must keep it turned on by sending in other commands or sending the PN ping command If no command is received in 3 minutes the subscription will be terminated A TCP host s subscription will automatically be terminated when the TCP connection is closed 3 39 TI get or set time Use the TI command to get or set the time maintained by the realtime clock The syntax is TI lt CR gt lt LF gt to get the current time or TLhour minute second
