User manual ALESIS RMD

[. . . ] The RMD is designed to rack-mount in a standard 19" equipment rack. Four RJ-45-terminated category 5 ("CAT 5") cables are used to connect the RMD to up to four M20s. The RMD accepts any AC voltage between 90 and 250 volts. · · · TABLE OF CONTENTS Important Safety Instructions and Compliance Notices . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Safety symbols used in this product. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Information to the User for Class A Digital Device (FCC Part 15, Class A) . . . . . . . . . . . . . . . 2 CE Declaration of Conformity. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Connecting the RMD to the M20 System . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Power. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Connection to M20(s) and CADI Autolocator . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 RMD Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . [. . . ] Unfortunately, the presence of a third ground pin does not always indicate that an outlet is properly grounded. Use an AC line tester to determine this. If the outlet is not grounded, consult with a licensed electrician. When the AC current is suspected of having unstable voltage and/or frequency, a professional power conditioner should be used. The RMD is supplied with a standard detachable power cord. 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. The RMD may be connected to up to four M20s. 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). To connect the RMD to a four-M20 system: 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. [. . . ] However, constant flashing means: · · The heads are dirty and must be cleaned, or The tape has dropouts and should be backed up onto a new tape as soon as possible. For a more accurate diagnosis, check the error rate counter in the display of the M20 whose indicator is flashing with a known "benchmark" tape (see section 4. 11 of the M20 manual). See Section 13. 20 of the M20 Manual for more information about the error rate counter, and contact your Alesis dealer for information about tape care, head maintenance and cleaning. R-6 RMD MANUAL 1. 00 Appendix R, RMD "B" Indicator (Red LED) When a transport or system error occurs, the B indicator for the erring machine will flash until reset by pressing the Peak Clear button on either the CADI or the front panel of the offending M20. If a "B" indicator lights, immediately look at the display of the M20 itself for an error message. Write down the error code and refer to Alesis Product Support for more information. Some less serious M20 system error messages are displayed momentarily. [. . . ]
