8 – Remote operation : Selecting devices for transport control94 TASCAM DM-3200 User’s ManualUp to 16 devices may be added to the Machine Con-trol List. If more devices are connected and added tothe list than can be shown on screen, arrow marksappear at the top and bottom of the list.When an entry in the Machine Control List is high-lighted (that is, the cursor is on the left of the screen),the dial is used to scroll through the list, includingthose items which may not be visible on the screen.Deleting devices from the listIf a device is added in error to the Machine ControlList (or is no longer required), move the cursor to theon-screen DELETE button, use the wheel to select thedevice and press ENTER. The item in the list will bedeleted.This process can be repeated to clear the list.Auto-detection of devicesIn addition to the manual addition of controlleddevices, there are two auto-detect buttons. One isused is used for detecting all devices attached to theDM-3200 (LIST AUTO DETECT) and the other is used fortransport mapping (see “Transport mapping memo-ries” on page 95 below).Move the cursor to the on-screen LIST AUTO DETECTbutton and press ENTER to scan the control ports andreport on the detected devices, adding the controllersto the Machine Control list (see “Transport mappingmemories” on page 95).NOTEBecause not every device that may be controlled by theDM-3200 is capable of reporting its presence accurately,some devices will not appear on the list, and must beadded to the list manually.When attempting to identify a MIDI device, the DM-3200 first sends out an MMC Read Signature com-mand. It adds a generic “closed loop” device forevery device ID that responds to this command.It also sends out a MIDI Device Inquiry Message. Ifa remote device replies to this message, and anappropriate controller is available, this controllerreplaces the generic MMC closed-loop controller.NOTEThe current version of the DM-3200 software does notsupport MIDI Machine Control. The paragraphs aboverefer to later versions.After power has been applied, it may take betweenone and two minutes for the remote devices to be rec-ognized. Even if they have been added to the memo-rized Machine Control list previously, it may not bepossible to control them immediately the system ispowered up.Selecting the control type for the devicesThe Machine Control list is composed of a number ofcolumns. These are explained below:STATE An icon shows the state of the controlleddevice. A one-way arrow represents an open-loopdevice (that is, commands are sent from the DM-3200 to the device, but no information is transmittedback from the device to the DM-3200 along the samechannel—information is transmitted from the otherdevice through a different channel, such as timecodeor MIDI).A double-ended arrow represents a closed loop,where information flows both ways between theremote device and the DM-3200 along the samechannel.A cross indicates that the device is not being con-trolled by the DM-3200.Two dashes (--) show that the type of control is notrelevant here (for instance, the internal MIDI time-code generator).DEVICE The name of the device being controlled,together with its control type. These list items cannotbe changed or edited.ID In the case of DTRS units, it refers to the unit ID,and cannot be edited. In the case of MMC units, itrefers to the MMC ID (up to three decimal digits) ofthe unit. This list item cannot be changed or edited.
