MULTI-TASKER Example: S = save configuration If one MT108-105 card is plugged in slot #2 of unit 3: If Outputs 1 and 2 are at volume level 16 and outputs 3 and 4 are at level 8, the feedback after sending the command [C4S], for slot 4, would be: Send the command [VERC2U3], and the Multi-Tasker™ Basic Enclosure will return the following feedback: Vol1=16/16 Vol2=16/16 Vol3=8/16 Vol4=8/16 MT108-105 690-0127-007 690-0127-007 = software version MT108-105 = card type: MT108-105 Card Status Saved 2.
MULTI-TASKER needed for execution. Insert a 200ms delay [WAIT] time after sending this command. Example: If cards 1, 2, and 3 are grouped as group 5 of unit 1, send the command [SEL1G5U1]. Then send the commands [ + ], and [ - ] to increase or decrease the volume for cards 1, 2, and 3 simultaneously. [CLRCnUi] Cn = card ID No. (n = slot # from 1 to 19) (1-8 for MT100-101 or 1-4 for MT100-106) Ui = Unit ID number (i = 0 to 9) 5.
MULTI-TASKER Ui = unit number (i = # from 0-9) TROUBLESHOOTING GUIDE Example: We have carefully tested and have found no problems in the supplied MT108-104/(105); however, we would like to offer suggestions for the following: To group cards #1, 2, and 3 as group 5 of unit #1, send the command [WRC1C2C3G5U1]. After executing this command, cards 1, 2, and 3 of unit 1 will be grouped together as group 5. 8 • 8.1 LED IS NOT LIT • 8.2 NO SOUND 11. [RD] • 8.3 SOUND DISTORTION • 8.
MULTI-TASKER source is working and there is still no sound, see Cause 2. 8.4 SOUND LEVEL IS LOW Cause 1: The volume inappropriate. Cause 2: The card output is turned OFF. Solution 1: Turn ON the card output that is used. See RS-232 accessible commands in section 7. If no sound is present, see Solution 2. Solution: are Solution 1: Turn up the source volume. If sound level is still low, see Solution 2. Solution 2: Turn up the destination amplifier volume. If the sound level is still low, see Cause 2.
