AJA RD5AD 2-Channel Analog to SDI Converter User Manual — Introduction

The AJA Video RDSAD is a dual-channel universal video A/D converter. The
RD5AD supports 2 completely separate channels of analog to SDI conversion and is
useful for video/key or video/video applications. Both channels can be independently
configured for YPbPr (SMPTE, EBU-N10), Betacam, RGB, composite or Y/C (S­Video) inputs. The RDSAD automatically configures NTSC (525 line) or PAL (625
line) analog inputs to 525 or 625 line 4:2:2 component serial digital output on each
channel. The full dynamic range of input video values below black and above white
are not clipped. In the NTSC mode, the removal of the 7.5 IRE pedestal can be
disabled by an external dipswitch selection.

Note:

Operation without use of a TBC is not recommended for VTRs, laser disks, DVDs,
etc.

A Time Base Corrected (TBC) source is required on the RD5AD inputs.

FR1 and FR2 BNC Connector Assignments, RD5AD Card Module

When the RD5AD module is installed in an AJA FR1 or FR2 frame, a corresponding
group of 9 BNCs on the rear panel then provide I/O for the module. The illustration
above shows the connector assignments for both the FR1 and FR2 when used with the
RD5AD.

The user interface for the RD5AD includes two
dipswitches, a six-position for control of Channel 1 and
another for control of Channel 2. Two LEDs provide status
indication showing whether video is present at a respective
channel. The following table under “ Control Functions”
shows what each of the dipswitch positions perform. Both
dipswitches function identically for their respective
channels. The channel number is marked on the front of
the circuit card next to each dipswitch.

S6 Comb Filter: ON (Down) = Comb Filter On (enabled with composite input only)

OFF (Up) = Comb filter Off (Notch filter used for composite input)

Typically, RD5AD installation consists of the following:

disconnect power from the frame (remove line cord)

remove the FR1/FR2 front panel

install RD5AD card module

apply power to the frame by connecting a north american-style power cord from the
frame to mains power (90 to 260 VAC)

Instructions for removing the frame front door for module installation is discussed in the

FR1/FR2 User Manual.
