@WORD SYNC connectors (BNC type)
A word sync signal of 44.1 kHz or 44.056
kHz is input to the WORD SYNC INPUT
connector or output from the WORD SYNC
OUTPUT connector.
@coMPOSITE SYNC connectors (BNC type) and
75-ohm termination switch
These connectors are input (COMPOSITE SYNC
INPUT 1, 2) and output (COMPOSITE SYNC
OUTPUT 1, 2) connectors for a composite
sync signal. To terminate the INPUT
connectors with 75 ohms, set the 75-ohm
termination switch to ON. Set the
termination switch to OFF to create a
looping output (bridge connection).
@STATUS output connector (25-pin D-sub
type)
Signals containing status information, such
as error flags, are output from this
connector. The connector's output circuits
except for the RS-422 circuits have
open-collectors.
