ICE-HE Ethernet Head End
Remote Control Connection
Attach appropriate RS-232 cable to the
Remote Control
RS-232 port. See page 5 for RS-232
cable wiring diagram.
The default setting is 19.2K baud – see page 4 for DIP switch setting information. Do not change
for use with Display Express systems.
Alternatively, connect via Ethernet, setup instructions on page 9.
RF Coax and iCC-Net Operation
Connect an RF coax feed from RF Out to the system’s RF combiner, mixing the iCC-Net Out signal
with the other CATV channels. The iCC-Net Out channel operates at 74.7 MHz, in between cable
channels 4 and 5.
When combining the RF output with QMOD modulators, add the included 20 dB attenuator – this
will lower the output to match the QMOD’s 29 dB
Using an RF signal level meter, use the front panel RF Out adjustment counterclockwise to match
the other sources, attenuates the level by up to -10 dBmV.
Do not connect any feeds to RF In.
AC Power and Net LED operation
Insert DC power supply plug into the Power In jack.
Plug power adaptor into AC wall outlet, the front-panel LEDs should turn on momentarily.
If iC-Net communication is functioning, the Net LED will twice per second.
I/O Port Connection
1.
A simple contact closure can be wired to I/O 1 or 2, a press or release can trigger events in the
PC or control system software.
2.
In other applications, the I/O ports can act as closure outputs, activating an external power relay,
2x1 video switcher or other device.
3.
You’ll have to choose application – the ports act as either an output or input, not both. See
Control Connections on page 5 for wiring and rating information.
