2.11.6 Cintel URSA Gold / URSA Diamond

URSA Gold telecines with firmware versions prior to 5.06 have different
internal timing with respect to the Film Frame pulse output. In order to
compensate for these timing differences you need to select the correct
telecine type using the KeyLog TRACKER™ software. Selecting the URSA
DIAMOND setting on the menu will give the correct timing for URSA
Diamond and URSA Gold telecines with firmware after 5.06.
URSA Gold telecines with firmware versions 5.01 and earlier had some
indeterminate timing related to the Film Frame pulse (which is connected to
the 4025TR) and certain other internal telecine pulses. These telecines
require factory upgrades from your Cintel Dealer in order to be compatible
with the 4025TR.
The Biphase tach pulse is available on a pair of BNC connectors on the
rear of the Mag follower. These biphase signals must be connected to pins
3 & 7 of the 9 pin parallel I/O D connector. Connect ground to pin 6 on the
rear of the 4025TR. Retain the separate shielding of each signal up to the
4025TR in order to prevent cross-coupling which can adversely affect the
biphase reliability.
Remove the coax cable connected to the Frame BNC (BSK 33) on the
telecine Digiscan frame, (if any) and connect it to one side of the FILM
FRAME loop on the 4025TR. Connect the other side of the FILM FRAME
loop to the Frame BNC (BSK 33)
Do not terminate this signal.
The telecine type item on the Engineering Toolbox Hardware Menu must
be set to URSA DIAMOND.
Toolbox Hardware Menu must be set to DIRECT. (See section 3.6.4 and
3.6.5)
For URSA Gold and URSA Diamond telecines do not use AUTO rate detect.

2.11.7 Bi-phase Accuracy Test

When you have completed the basic telecine connections, you will need to
verify the frame accuracy of the basic system. Once you have verified the
basic connections, you may proceed to the KeyKode reader installation.
If you do not verify the frame accuracy of the system at this time, the
accuracy of your system with KeyKode will also be affected.
