RS-232 Cabling
For RS-232, use a standard CAT-5 cable (568B termination for RJ-45 connectors) from the RS-232 port
on the back of a Vaddio ProductionVIEW camera controller or switcher. If the camera will be connected
to a third-party control system (such as AMX® or Crestron®), a DB-9 to RJ-45 adapter cable is supplied
with the camera for RS-232
.
Videoconference Codecs and RS-232
Depending on the codec that is used, and which RS-232 port is used with a codec, special DB-9 to RJ-45
adapters may sometimes be required. Refer to Vaddio’s price list or website for Tech Notes on the HD-
18 page on specific diagrams for wiring the camera to videoconference codecs.
Remember to always power up the cameras before booting up the codec.
Daisy Chain Configurations/Installation Instructions: In some cases, Daisy Chain control situations
can’t be avoided. Because of this, Vaddio added “Daisy Chain Control Emulation” or DCCE™ to the
Quick-Connect DVI/HDMI - SR Interface in order to use the HD-18 camera in these situations. See
Connectivity Example 2 (previous page) where the codec requires daisy chain control wiring.
1) For Daisy Chain control, first complete steps 1 through 3-d, since all the cabling between the cameras
and the Quick-Connect is the same.
2) Instead of running a cable from the 1
st
camera to the 2
nd
camera, run a Cat 5e patch cable from the
1
st
Quick-Connect interface RS-232 CONTROL DAISY CHAIN RJ-45 jack to the 2
nd
Quick-Connect
RS-232 CONTROL INPUT jack. Within the VISCA® like protocol that the codec and the HD-18’s
use, the 1
st
in the chain will set up as Camera #1 and the second will set up as Camera #2 in the
chain allowing the codec IR Remote to Select which camera it will switch to and which to control.
a. In the case of TANDBERG Codecs, the IR Modulated Output of the Quick-Connect and a
Xantech IR emitter (282D or 283D) attached to the front panel of the codec (in front of the IR
receiver).
b. Polycom Codecs with IR receivers can connect the IR Feed Through the same way as the
TANDBERG, but do not use daisy control. Several Polycom codecs can also be connected
directly with the non-modulated signal to the codec’s IR signal input port.
