Page 3: Introduction
• Owner’s Manual & Registration card 2.2. INsTaLLING THE sR-112 The sR-112 is designed to be mounted in a standard 19” rack. It requires 1U in height. Usual precautions should be respected when wiring the sR-112: use high quality cables with good shield to guarantee a good signal transmission. -
Page 4: I/O's Description And Cable Requirements
Plug the supply into the wall using the standard IEC cable supplied. 3.2 ETHERNET The Ethernet port is used to connect the sR-112 via TCP/IP protocol to access the unit remotely and to upload firmware from any computer on the network. -
Page 5: Quick Start
Connect your time code source to the XLR TC input and, if available, connect your video reference to the video input BNC. Out of the box, the sR-112 is set to reshape and distribute your time code source through its 12 outputs. Output levels are set to 0dBU. -

LED is on. To exit the set Up mode, simply press the [sET UP] key again. Note: Holding the [SET UP] key for 3 seconds or more will reset the SR-112 (see 10.5 for more on Reset). 6.2. ENTER kEY In sET UP mode, scrolling through the different values will not affect anything. -

However some equipment may not be able to read time code if its rise time is too long. The sR-112 has three preset rise times for its output waveform: 1µsec, 20 µsec and 40µsec. The first one is a square wave, the third is per sMPTE and EBU... -
Page 12: Time Code Analyzer
Page 12 SR-112 User Manual (Rev 4.01) as a general rule, if time code is patched directly into a reader, use the square wave position; but, whenever possible cross-talk problems exist (i.e. in an audio patchbay...) or when recording the reshaped signal, use the sMPTE/EBU setting . -
Page 13: Video Phase
By default, the sR-112 considers time code in phase with video if the phase is within + or - 20º. If required, this window can be changed by adjusting the “Out Of Phase Threshold”... -
Page 14: Reporting Time Code Errors
When using 2x video rates (50, 59.94, 60Hz) for checking phase of a timecode input the sR-112 extracts a 1x rate (25, 29.94, 30Hz) from the video, and it does this by arbitrarily discarding every second input video frame edge. -
Page 15: Power-Up Error Blackout
The beeper sounds when a fatal error is detected. It can be deactivated in menu 06. Warning LED: after the sR-112 has detected a “fatal” error, the INPUT ERROR warning LED starts flashing. This way, if you leave the room, you will know if an error occurred while you were away. -

12. Ethernet The Ethernet port is used to connect the sR-112 via standard TCP/IP protocol. It enables the user to access the sR-112 remotely, and to upload firmware from any computer on the network, including mobile devices such as tablets or smartphones. - Page 17 The report header includes the start time, the Time Code format and rate, the video format and the TC/Vid phase (if video is present), the User Bits and the sR-112 operating mode. The current date is inserted at top of report. It is also inserted into the report at reader 24-hour crossing.

Page 18: Firmware Updates
When downloading firmware updates from the Brainstorm website, 2 types of image files are available: complete and software. The sR-112 FLasH memory is divided in several sections, for the parameters settings, the application software, the Loader software and the FPGa image. The diagram... -
Page 19: Programming Errors
• at the conclusion of a Flash programming sequence following the upload of a “complete” image file, the display shows that a manual reboot is required. • With a ‘software’ image file, the sR-112 automatically reboots. 13.4 PROGRaMMING ERRORs If an error occurs during the programming sequence, possibly due to a network error, a power failure or a pulled cable, one of 3 error messages appears in the LCD display. -

THE FACTORy. 13.5 LOaDER The Loader is a fall-back web page that allows you to restore your sR-112 in case of a programming failure. This page is located in a different area of the Flash Memory (see LOaDER sOFTWaRE on the Flash Memory map above, 13.2). -
Page 21: User Bits
(Binary Group Flags) are used to define this: BGF0, BGF1, BGF2 (see appendix D for sMPTE & EBU bit assignments). While in the User Bits page (see 5.1), the sR-112 LCD shows the User Bits and the BGF setting. The table below shows the different options available and how they appear on the... -
