2-3. Rack Mounting Requirements - Continued.
c. Space Requirements. Approximately 24 inches of clearance is required directly in front of the rack.
When the TD-1337(V)/G is pulled out on the slides, there must be sufficient clearance to service the sides,
top, bottom, and rear of the unit. The rack must contain adequate space to make the necessary cable
connections, with service loops, to the rear of the TD-1337(V)/G.
d. Location in Rack. When mounting the TD-1337(V)/G in a rack, choose a location in the rack that
is not at the extreme bottom or top of the rack. Operator actions are accomplished at the keyboard and
display located on the front of the TD-1337(V)/G. Organizational maintenance tasks will require access
to the top of the TD-1337(V)/G when it is pulled out on the slides.
2-4. Interface Connector Data.
All external connections are made to connectors J1 through J12 located cm the rear of the TD-1337(V)/G.
As explained in paragraph 1-10, each TD-1337(V)/G model has a different complement of rear connectors.
The following chart provides data as to what type connector will mate with each TD-1337(V)/G rear connector.
Paragraph 2-5 lists the signals for each pin of each rear connector.
