1.2 Optional Modules
The following options are available:
V: VITC generator
• VITC contains the same time and binary groups information as
the LTC.
C: Colour lock for the
625/50 (PAL)
television system
• 4-field and 8-field, 8-field using the white flag of line 7 of a
black-burst input.
L: LTC play speed
reader, 80-bit and
112-bit code
• LTC Jam-Sync functions,
• LTC refresh and regeneration,
• LTC source synchronisation,
• display of the VTR-LTC in the MTD system,
• converter of a 112-bit code to a 80-bit code.
G: GPI
• Relay closure at a programmable time.
2: RS232
4: RS422
• Instead of the RS485 interface used to communicate within the
MTD system a RS232 or RS422 serial interface can be used to
remote control the unit.
P: Pulse outputs
• Seconds pulse output and minutes pulse output.
A: Analogue Master
Output
• Output to drive analogue clocks with hands.
* Special solutions:
• Additional independent unbalanced LTC output (at BNC).
• Special software according to customer’s need.
• Special hardware according to customer’s need.
Additionally there are the following configurations to realise a reference time input. The
reference time can set the internal clock at various user definable terms.
DCF IN: DCF77 radio
clock receiver built-in
• Reference time = Central European Time (CET/CEST)
transmitted from the German DCF77 transmitter.
GPS IN: GPS receiver
built-in
• Reference time = a time derived from the GPS time, e.g. the
UTC.
Standard: Interface to
connect an external
DCF77 or GPS
receiver
• Input second pulse and serial data of an appropriate external
unit.
T: Built-in real time
clock module
• Time and date will be set by the buttons of GM-TTT. The
module has a real time clock with a battery backup.
