The BPH1 and BPH2 inputs (pins 3 & 7 respectively) should be connected
to bi-phase quadrature tach pulses from the telecine. The 5550 is factory
set to accept biphase at a rate of 10 pulses per film frame. To select
another rate use the Engineering Setup menu.
To enter the Engineering SETUP menu press the SHIFT + SETUP keys.
Press the down arrow key ($) until you have selected the biph menu
item. If the biphase rate is incorrect, press the % key to select other rates.
When you have made the desired change, press the SETUP key to return
to the normal display mode.
In order for the 5550 to use the fully automatic reader intensity features you
must select kk auto intens in the SETUP and tach hunt on in the
Engineering SETUP menus. (See section 3.1.4 for more information about
the SETUP menus).
A 9 pin D connector on the rear of the KeyKode decoder labeled SERIAL
I/O provides RS-232 serial data communications with the 4025 or 4025TR
Film Footage Encoder. Use the cable supplied (Part No. WA-C67) or wire
a longer cable if required. Wiring information for the WA-C67 cable is as
shown in Figure 2-4. Maximum suggested length of this cable is 50 feet,
although longer cables may be used if the wire size is made larger. Care
should be taken to ensure that shielded cable is used, and that the shield is
connected through. Connect this cable to the SERIAL I/O connector on the
rear of the 5550. Connect the other end of the cable to the AUX I/O
connector on the 4025 or 4025TR.
