Front Panel

RF Out Adjust: Trims iCC-Net channel output, shipped set to +55 dBmV
RS-232 TX LED: Yellow LED, lights when receiving RS-232 data on Control or iC-Net RS-232 port
RS-232 TX LED: Yellow LED, lights when receiving RS-232 data on Control or iC-Net RS-232 port

Flashes twice per second if the number of present and expected devices do not match
COM LED: Yellow LED blinks when a valid command is received or system response sent through the Control port
Error LED: Red LED indicates a problem within the unit
Reset/Default: White button sends press and release response to PC software or control system
Emergency: Red button sends press and release response to PC software or control system
Ethernet LEDs: RX/TX LEDs indicate Ethernet data send and receive

Ethernet: 10/100baseT RJ-45 jack, RX/TX LEDs indicate Ethernet data send and receive
Ethernet LEDs: Right bicolor LED indicates 100baseT data activity, green indicates full duplex, amber half duplex
Left bicolor LED indicates 10baseT data activity, green indicates full duplex, amber half duplex
Control RS-232: DB9 female, RS-232 data link to control system or PC
iC-Net RS-232: DB9 female, RS-232 data link to send iCW-Net over fiber (with fiber RS-422 interface) or codec
I/O 1 & 2: 4-pin captive screw terminal for Input/Outputs 1 and 2, 2 switch closures or inputs, max 50 mA, 24 VDC, switch to GND
I/O Applications: DC power - close pins 1 & 3 to provide DC on/off
Dry closure 2 - close pins 3 & 4 for dry contact to external power relay, AMX PC1 or similar
Sense closure (3 & 4) on Input 1 - trigger control system to power off for all rooms
iC-Net Expand: RJ-11 female 6-pin Telco jack, CAT3/CAT5 compatible unshielded, max 3,300 feet [1 Km] from Head End
Power In: 2.1mm coaxial jack (inside center conductor positive), 300 mA maximum
11 to 18 VDC, 12 VDC typical (may be unregulated)

iCC-Net Connections

RF In: 'F', female, 75 ohm impedance, RF and iCC-Net from CATV system
Data Receive: Carried over the same RF coax connection as TV channels Return signal from system controllers
Sub-band, 5.6MHz, narrow-band signal below standard sub-band channels
-15 to +35 dBmV signal level (0 to +15 dBmV nominal)
RF Out: ‘F', female, 75 ohm impedance, RF to CATV distribution to TVs, tuners, and controllers
Data Transmit: Mid-band VHF, 74.7 MHz, narrow-band signal between channels 4 and 5
± 80 KHz max carrier deviation, +55 dBmV maximum (default)

iCW-Net Connections

iCW-Net 2, 3: RJ-45 female 8 pin Telco jack, supports 3300 ft [1 km] of wire, RS-422 type data requiring at least 2 twisted wire pairs with shield or fifth conductor - use Category 5 or Category 3 wire, 4 pair, unshielded, 24 AWG.
iCW-Net 1: 6-pin captive-screw terminal for system wiring or use with RS-422-format fiber or codecs

The ICE-HE includes three iCW-Net ports for twisted-pair wired networking. Control wiring can be home-run to ports or run in a star format, using punch-down blocks or RJ-45 “harmonicas” to distribute signals to multiple iCW-Net devices. Open wiring runs do not need termination.

Includes
