Installing the Optional Video Sync Boards in the RB-DSD1
There are 2 optional video sync boards which can be used to synchronise the outputs of the
RB-DSD1 to a 48kHz sample rate from an analogue or digital video signal:
RB-SYA
- The Analogue video sync board will accept a composite signal of NTSC (525), PAL
(625) & SECAM (625) signals covered by SMPTE-170-M (NTSC) and ITU-R BT.470-6 (PAL &
SECAM).
RB-SYD
- The Digital video sync board will accept 270Mbps SD-SDI and HD-SDI signals
covered by SMPTE-259-M-C (SD) and SMPTE-292M (HD).
Opening the RB-DSD1
Warning: The power must be switched off at the supply or the power lead must be
disconnected before attempting to open the unit. Removal of the cover can expose
dangerous voltages.
1. Remove the 4 screws in the corners of the rear panel.
2. Remove the 4 screws on the top and bottom panels which hold the rear panel in place (2
on the top and 2 on the bottom).
3. Remove the screw in the centre of the front panel.
4. Slide the rear panel and main PCB backwards out of the metal chassis giving you
internal access.
5. Remove the rubber grommet/bung on the rear panel which covers the hole for the video
sync connector.
6. Remove the 2 screws from the bottom of the sync card pillars and, making sure to keep
the plastic washers in place at the bottom of the pillars, fit the 20 way pin header into the 20
way connector on the RB-DSD1 motherboard.
7. Underneath the board, insert the 2 screws to fix the board in place.
To put the unit back together, slide the PCB back into the chassis and refit the screws in
reverse order.
The video synchronisation is chosen using the front panel DIPSwitches (see page 6).
Follow these instructions to fit either of the sync boards.
