11 - Machine Control/Location-Selecting devices for control When an entry in the Machine Control List is highlighted (that is, the cursor is on the left of the screen), Deleting devices from the list If a device is added in error to the Machine Control List (or is no longer required), highlight the device, Auto-detection of devices In addition to the manual addition of controlled devices, there are two auto-detect buttons. One is used is used for detecting all devices attached to the DM-24 (LIST AUTO DETECT) and the other is used for transport mapping (see "Machine Control mapping memories" on page 82 below). Move the cursor to the on-screen LIST AUTO DETECT button and press ENTER to scan the control ports and report on the detected devices, adding the controllers to the Machine Control list (see "Machine Control mapping memories" on page 82. NOTE Because not every device that may be controlled by the DM-24 is capable of reporting its presence accurately, some devices will not appear on the list, and must be added to the list manually. Selecting the control type for the devices The Machine Control list is composed of a number of columns. These are explained below: STATE An icon shows the state of the controlled device. A one-way arrow represents an open-loop device (that is, commands are sent from the DM-24 to the device, but no information is transmitted back from the device to the DM-24 along the same channel-information is transmitted from the other device through a different channel, such as timecode or MIDI). A double-ended arrow represents a closed loop, where information flows both ways between the remote device and the DM-24 along the same channel. A cross indicates that the device is not being controlled by the DM-24. Two dashes (--) show that the type of control is not relevant here (for instance, the internal MIDI timecode generator). the dial is used to scroll through the list, including those items which may not be visible on the screen. move the cursor to the on-screen DELETE button, and press ENTER. The last item in the list will be deleted. This process can be repeated to clear the list. When attempting to identify a MIDI device, the DM24 first sends out an MMC Read Signature command. It adds a generic "closed loop" device for every device ID that responds to this command. It also sends out a MIDI Device Inquiry Message. If a remote device replies to this message, and an appropriate controller is available, this controller replaces the generic MMC closed-loop controller. After power has been applied, it may take between one and two minutes for the remote devices to be recognized. Even if they have been added to the memorized Machine Control list previously, it may not be possible to control them immediately the system is powered up. DEVICE The name of the name of the device being controlled, together with its control type. These list items cannot be 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, it refers to the MMC ID (2 hexadecimal digits) of the unit. This list item cannot be changed or edited. Use the JOG dial to change the value and confirm with ENTER. CHASE This applies to DTRS units, and allows the CHASE mode of the selected unit to be turned on or off. Any unit which can have its chase mode controlled by the DM-24 has this item represented by a square box. Units whose CHASE mode cannot be remotely controlled have this item represented by two dashes (--). Use the cursor keys to navigate to the list item, and the ENTER key to toggle between on (a check mark is shown in the box) and off (the box is empty). TASCAM DM-24 Reference Manual 81
