Input and Output Ports
Connections to the CNXRMCLV are made through the ports on the front and rear
panels. Refer to the illustrations and descriptions, which follow.
AUDIO
The RJ-45 AUDIO port is used to transmit and receive analog stereo audio from the
head end. Refer to the diagrams on page 7 for pin configurations.
VIDEO OUT
The RJ-45 VIDEO OUT port can be used to send up to four baseband video signals
out of the unit and back to the head end. A Crestron (CNX-PBVR4) or third-party
video receiver must be used to convert to single-ended RCA for input to the
CNX-PVID. Refer to the diagrams on page 7 for pin configurations.
VIDEO IN 1-2-3-4
The RJ-45 VIDEO IN port connects to a video distribution box such as the
CNX- PVID8 and accepts four baseband/balanced video signals corresponding to
each of t he four levels provided by the CNX-PVID8. This connection can distribute
high
definition component video and multi-channel digital audio, or combinations
of S-video and/or composite video. Three of the video signals have cable length
compensation. The fourth video signal has fixed compensation and can be used for
composite video or digital audio distribution. Refer to the diagrams on page 7 for pin
configurations.
Each local video source input has a built-in video sensor.
RS-232
The CNXRMCLV provides one RJ-11 connector for RS-232 communication with
serial devices. This port supports baud rates of up to 115K and RTS/CTS hardware
handshaking. The pins are configured as shown in the following table:
Pin Function
1 CTS (Clear to Send)
2 GND
3 RXD (Receive)
4 TXD (Transmit)
5 RTS (Request to Send)
6 Not connected
VIDEO IN (5 - 8)
These four RCA connectors provide for video input (any combination of composite,
S, or component, including HDTV), with built-in 75-Ohm termination.
VIDEO OUT (A – H)
These eight RCA connectors provide local (analog) video outputs.
Local audio can be routed to the head end, from where it can be distributed to a room
via speaker level from the CNX-BIPAD8/CNAMPX-16x60 combination. Local
audio sources can also be routed to the record-out outputs. The unit’s primary audio
