User manual ALESIS RMD

[. . . ] 22-segment Vacuum Flourescent Display (VFD) bargraph meters indicate the levels for up to 32 tracks (4 M20s). Display settings for the RMD (Meter Scale, Decay Time, and Peak Hold Time) are set on the M20 or the CADI (see M20 manual Chapter 7, "Metering"). The RMD will indicate transport or system error messages, and interpolation errors by using eight LEDs provided in the center of the RMD's front panel. The RMD is designed to rack-mount in a standard 19" equipment rack. [. . . ] The RMD ships with an IEC-spec power cord for the country to which the RMD was shipped. The RMD's IEC-spec AC cord is designed for connection to an outlet that includes three pins, with the third pin connected to ground. Do not substitute a non-grounded AC cord or lift the ground. The ground connection is an important safety feature designed to keep the chasis of electronic devices such as the M20, CADI remote, or RMD at ground potential. Unfortunately, the presence of a third ground pin does not always indicate that an outlet is properly grounded. When the AC current is suspected of having unstable voltage and/or frequency, a professional power conditioner should be used. If the AC cable is too long or short for the installation, you may substitute a UL-approved power cable of the proper length, available in many electronics or computer stores (type "NEMA to CEE"). CONNECTION TO M20(S) AND CADI AUTOLOCATOR The RMD comes with one 25-foot long RJ-45 category 5 terminated (control) cable for connection to one M20. If installation requires a longer cable (or more cables), use highquality category 5 spec'ed cable. Exceptional cable lengths of 1000 feet or more can be used, depending on the quality of the cable. If an RMD is to be used in conjunction with an M20 and the CADI autolocator/remote control, an RJ-45 connector labeled "CADI" is provided on the back panel of the RMD for connecting the CADI remote (see figure 1). Connect one end of a control cable to the REMOTE connector on the first M20 (tracks 18), and connect the other end to the MACHINE 1 connector on the RMD. Connect one end of a control cable to the REMOTE connector on the second M20 (tracks 9-16), and connect the other end to the MACHINE 2 connector on the RMD. Connect one end of a control cable to the REMOTE connector on the third M20 (tracks 17-24), and connect the other end to the MACHINE 3 connector on the RMD. Connect one end of a control cable to the REMOTE connector on the fourth M20 (tracks 25-32), and connect the other end to the MACHINE 4 connector on the RMD. To connect the RMD to a CADI: R-4 RMD MANUAL 1. 00 Appendix R, RMD 1. Connect one end of a control cable to the REMOTE connector on the CADI, and connect the other end to the connector labeled "CADI" on the RMD. Communication between the CADI and the M20(s) happens via the RMD connection to the first (ID 1/Master) M20 using the MACHINE 1 connector. Do not connect the first machine directly to the CADI when the RMD is in use. M20 CADI M20 M20 M20 RMD MANUAL 1. 00 R-5 RMD, Appendix R RMD OPERATION POWER-UP The RMD does not have to be powered up in any order with respect to the M20(s) or the CADI for it to work properly. The power switch is located on the left side of the RMD's back panel. When the RMD is powered up, the track number indicators at the bottom of each meter will light with the appropriate track number (tracks 1-32). If M20s are connected, the Record and Input Enable status of each M20 will be reflected in the RMD's display at power-up. In an M20 system that has a CADI connected, the RMD does not have to be on in order for communications to occur between the Master M20 and the CADI. [. . . ] Some less serious M20 system error messages are displayed momentarily. If a red LED is flashing on the RMD and there is no error message displayed on the corresponding M20, make a note and monitor that machine's performance more carefully. Transport or system errors are NOT the same as digital audio errors. However, if the "B" indicator is accompanied by "A" errors, it is likely that the tape or head is having difficulty reading the time markers necessary for proper operation and that a head cleaning or tape backup is necessary. Other errors include when the selected system clock is running too fast or too slow, or if the M20 has detected problems in the tape drive. [. . . ]
