using transformers, because of inher-
ent protocol differences between the
AES-3 and S/PDIF formats. Rane
Corp. has a well-written application
note (www.rane.com/note149.html)
which addresses AES/EBU and
S/PDIF signal interfacing.
2.3.6 USING A STUDIO REMOTE PANEL
A 44-pin D-Sub connector ( Remote I-O Logic )
allows remote control and delay status indication
for the HDE-200. It’s typically wired to a
studio-mounted remote panel like the six-button
Harris Control Panel (Harris p/n PRE99-1212).
The
Remote I-O Logic interface block diagram,
shown on page 2-8, is divided into three main sec-
tions: Diversity Delay; Profanity Delay; and Other
controls and tallies/status indicators. Each
section’s inputs and outputs are separately enabled
by jumpering pins on the panel to +5 VDC or Logic
Ground, for most applications.
All logic connections (see the signal summary
on this page) are opto-isolated through using opto-
couplers on the inputs and solid-state “dry-con-
tact relays” on the outputs.
To maintain complete isolation, do not use the
+5 VDC Logic Supply or the Logic Ground pins
when connecting the
Remote I-O Logic connector
to active peripheral devices. Power and ground
should be sourced from the peripheral device.
The +5 VDC Logic Supply and Logic Ground
connections are intended for use with a studio
remote control panel only.

Logic Inputs
Each input section must be enabled by
jumpering its Enable pin to a + voltage source
like +5 VDC (logic signals from +5 to +40 volts
can be used). Logic inputs are activated by pull-
ing the input pin low.
When a studio remote panel is connected, the
enable pins are jumpered to +5 VDC Logic Sup-
ply pins. Likewise, the remote panel switches are
typically commoned on the panel, which is tied to
a Logic Ground pin in order to generate the low
logic. This is shown in the Using a Studio Remote
Panel with the HDE-200 illustration on page 2-9.
Logic Outputs
Each logic output section has its own Tally Com-
mon connection that can connect to either a + volt-
age or to ground, depending upon the application.
The logic outputs (tallies) typical drive LEDs
in a studio remote panel. One end of all of the
status LEDs on the studio panel are typically
commoned together to connect to the +5 VDC
