Head End Installation
Some SignStream applications run HDTV playlists only, other applications include CR iC-Net technology to
control displays through the same RF coax as the HDTV channels. In systems that provide control a
Contemporary Research ICC-HE Head End is installed near the SignStream media player. This unit receives
control commands via RS-232 and inserts the commands into the RF system as a small control channel between
TV channels 4 and 5. If your SignStream system is not used to control displays, ignore this section. Refer to the
ICE-HE manual for Ethernet communication to Head End.
RS-232 Control
Most applications will use RS-232 communication, connected to an ICC-HE Head End. Check the front panel of
the Head End, as shown above, and see if the last 3 DIP switches under the RS-232 LED are set as follows:
•
Switch 6 Off (Down)
•
Switch 7 On (Up)
•
Switch 8 On (Up)
This sets the speed of communication to 19,200 baud.
Next, connect the included RS-232 cable between the 9-pin RS-232 port at the SignStream back panel to the
RS-232 Remote Control port on the back of the ICC-HE.
