Connecting Linear Time Code

There are eight Longitudinal Time Code (LTC) interfaces (four inputs and four
outputs) incorporated in the DB25 connector on the rear panel of the Reference
Genlock circuit board. Table 3-2 lists the pin assignments for the DB25 connector.

An eight-connector DB25-XLR breakout cable (shown in Figure 3-13 is available as
an optional accessory. The XLR connectors are labeled to correspond with the inputs
and outputs listed in Table 3-2.

NOTE: The DB25-XLR breakout cable is also used to connect the Audio circuit
board to the XLR100 as described on page 3-14.
