DIP-switches. These switches are
accessible behind a removable panel,
located above the 25-pin connector on
the back plate of the camera. Figure 3
illustrates the timing details in Master
Mode.
Slave Mode is to be selected when the
camera’s operations are to be synchro-
nized with the user’s unique system.
In slave mode, the camera requires an
external Master Clock signal (MLCK)
to define the output video data rate,
as well as a properly timed Line
Transfer (LT) signal to initiate the line
readout. Figure 4 illustrates timing
details in slave mode. Table 1 details
correct DIP-switch settings for both
Master and Slave Mode.
Within slave mode, there are two
alternative settings for unique appli-
cations. Alternative Slave Mode 1
allows the user to supply the camera
with Line Reset (LR) and LT signals,
but allows the camera to run at the
maximum data rate determined by the
internal oscillator. Alternative Slave
Mode 2 instructs the camera to ignore
LR signals, which allows users to
bypass the exposure control feature
of the camera. Table 1 details all DIP-
switch settings for all operating
modes.
