2.1 INSTALLATION
2.1.1 MOUNTING
Physical dimensions and outline of the transport· are
shown in Figure 1-1. The transport requires 4.56
inches of mounting space on a 7.5 inch rack.
The
transport should be located so that the cabling length
between the transport and the format control unit is
no longer than 20 feet.
2.1.2 SERVICE ACCESS
The two circuit boards are readily accessible without
dismantling the chassis. To gain access to the mech-
anical parts inside the chassis, detach the connectors
and Write Head Driver board from the Transport
Electronics board. Then detach the Transport Elec-
tronics board from the bottom of the chassis (four
nuts).
The front and sides of the Model 331 are
easily removable as one unit for making certain
mechanical repairs.
2.1. 3 INTERCABLING AND POWER CONNECTIONS
The connector pin· aSSignments and cable require-
ments are specified in Section

of this manual. An
external power supply is required for the tape trans-
port.
It
may be purchased directly from the Kennedy
Company or may be acquired elsewhere. The power
supply connections and specifications are detailed in
Section I.
2.2 OPERATION
Before operating the unit, make certain that all power
supply and formatter connections have been made.
