Chapter 1: Introduction

Product DescriptionThe IRB-3901 Timecode Converter converts two channels of SMPTE/EBU timecode into IRIG-B timecode, and converts two channels of IRIG-B timecode into SMPTE/EBU timecode. The module operates as a standalone product installed in a NEO 1RU or 3RU frame, and can work in conjunction with other Leitch clock products, including the following:• CSD-3901 and CSD-3902 Clock System Drivers• GPI-3901 General Purpose Interface• DTD-5230 Digital Clock Display• MTG-3901 Master Timing GeneratorThe IRB-3901 requires very little maintenance, and all of its controls can be accessed at the card edge. Like other NEO modules, the IRB-3901 can also be controlled remotely, using control panels and GUI-based CCS control applications. Certain conditions apply, however. See page 10 for details.

Main FeaturesThese are the main features of the IRB-3901 Timecode Converter:• Four timecode inputs, consisting of two separate IRIG-B

unbalanced BNC inputs (with AFNOR NF S87-500 support) and two separate SMPTE/EBU balanced timecode inputs

• Four timecode outputs, consisting of two separate IRIG-B unbalanced BNC outputs (with AFNOR NF S87-500 support) and two separate SMPTE/EBU balanced timecode outputs

• User-selectable leap year/non-leap year input • Card-edge LED indicators for SMPTE/EBU and IRIG-B presence• Free-running timecode output to compensate for temporary

timecode input failure

NoteAnfor is a non-broadcast timecode which enables the IRB-3901 to take the year information from the input to the corresponding TC output and IRIG-B output. If all the inputs have year information, you do not need to set leap year/non-leap year input.

Chapter 1: Introduction

SMPTE/EBU vs. IRIG-B TimecodeTimecode systems are used in diverse applications, including institutional clocks, communications, broadcasting, data handling, aircraft tracking, and security.Throughout the world, a number of different types of timecode exist. Each one has its advantages for specific applications. The Leitch IRB-3901 module brings compatibility to two different timecode formats: SMPTE/EBU—which is widely used throughout the world in broadcasting, video, and film production—and IRIG-B, a format relied upon by many government, military, and industrial users.

Remote/Local Control LimitationsA white sticker is located on the top of the CU1 socket in the middle of the module. This sticker identifies the module’s firmware. If the white sticker reads U1 1v1 AB0A, the IRB-3901 module supports CCS control hardware and software applications.• When you set the Remote/Local switch to LOC, you can only

control the module locally.• When you set the Remote/Local switch to the middle setting, you

can only control the module locally. This differs from other NEO modules, where both remote and local control are available from the middle setting.

• When you set the Remote/Local switch to REM, you can only control the module remotely.

The Remote/Local Switch parameter in CCS software applications indicates whether the module is in local or remote control mode.If the white sticker has another value, there is no remote control option.

NoteUnlike with other NEO modules, CCS software applications do not indicate with the “Ready (no remote control)” message when the IRB-3901 Timecode Converter module is unavailable.

Chapter 2: Installation, Removal and Operation

Leap Year and Normal Year SettingsThe Year switch allows the timecode converter to adjust for the extra day that is generated in each four-year leap cycle. Since the IRB-3901 counts days (and not months and days together), it does not have to be switched over during the leap day (February 29). The Year switch can be positioned to either Leap or Normal without turning off the module’s power.

Setting to a Leap YearWhen setting the IRB-3901 for a leap year, the Year switch must be set to Leap before the last day of February (that is, before the 29th day.)For example, during the leap year of 2008, the switch can be set to Leap at any time between 12:01 a.m., January 1, 2008, and 11:59 p.m., February 28, 2008. This allows the module to accurately show that December 30 is the 365th day, and December 31 is the 366th day.

Setting to a Normal YearTo resume a normal year of timecode conversion, the Year switch must be set to Normal before the last day of February. For example, during the normal year of 2009 (the first year after a leap year), the switch can be set to Normal at any time between12:01 a.m., January 1, 2009, and 11:59 p.m., February 27, 2009. This allows the module to accurately show that December 31 is the 365th day, and that January 1, 2010 is the first day of the next year.

NoteIf all the inputs have year information, you will not need to set the leap-year/non leap-year input.

Free-Run OperationIn the event of loss of timecode input, the IRB-3901 will free run and continue to generate timecode. The free run timecode is generated by a VCO (Voltage Control Oscillator), which will operate with an error rate of 8.64 seconds every 24 hours, until normal timecode input is restored.
