Operating instructions

2.4 Connections
Before connecting cables to the MTR-90III, it is recommend that the 2 rubber
bumpers supplied be screwed into two of the 4 corners of the chassis on the
rear of the machine (the corners chosen depend on the specific installation).
The bumpers help guard cable connectors from inadvertent damage.
2.4.1 Cable Connections
1. Locate and install the following cables supplied with the MTR-90III
(there will be 4 cables if the Auto Locator is installed, 3 if not) as shown
in Figure 2-8. All chassis connectors are clearly labeled with the
corresponding functions. BE SURE ALL CONNECTORS ARE POSITIVELY
MATED otherwise the tape machine may behave erratically.

MTR-90III Logic and Power Connections
❑ Remote cable for transport logic:
(37-pin Cannon D connectors). The female end of the cable plugs into
the rear of the MTR-90III, and the male end into the Remote Control
Unit. They should then be secured with the two screws supplied.
❑ Two remote cables for mode switching (CH 1–12 and CH 13–24):
(50-position AMP connectors). These two cables are identical and have
male connectors on both ends. Carry out correct connections taking care
not to make mistakes. A clip-lock is attached to the female side (Panel
side). Spread the clip fully open, insert the cable, then snap the lock
forward to lock the cable in place.
CAUTION: Be sure to follow each cable through from MTR-90III to Remote
Control Unit. If a single cable is inadvertently looped between adjacent
connectors on the MTR-90III or Remote Control Unit, circuit damage could
result. Such damage is not covered by the Otari Warranty.
