FR1 and FR2 BNC Connector Assignments, RD10MD2 Card Module
When the RD10MD2 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 RD10MD2.

The user interface for configuring the RD10MD2 and
selecting output formats is a pair of dipswitches at
the front of the card and several jumpers in the
middle and at the back of the card (see J2, J3, J5, and
J6 in the photo below).
Two multi-color LEDs at the front of the card
1
additionally show the type of input present at each
channel (HD=Orange or SD=Green).
The loop outputs always reflect the reclocked input.
Each channel has a reclocked looped output.
2
The format of the downconverter outputs, either SDI
1
or analog composite, are configured by the jumpers
J5 and J6. Jumpers J2 and J3 configure the HD to SD
delay and the type of embedded timecode (RP188 or
RP215). Tables later in the manual define the jumper
settings and their corresponding meanings.
