Input and Output Ports
Connections to the CNXRMC are made through the ports on the front and rear
panels. Refer to the illustrations on the previous page and the descriptions that
follow.
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 the 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 signal routing diagram on
page 10 for pin configurations.
Each local video source input has a built-in video sensor.
VIDEO OUT (A – G)
These seven RCA connectors provide local (analog) video outputs. Refer to
“Audio/Video Signal Routing” on page 9 for configuration suggestions.
RS-232
The CNXRMC 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
IR IN / IR OUT
The CNXRMC provides one infrared (IR) input, which is a mini phone jack that can
connect to a Crestron IR detector (CNXRMIRD) to detect fixed low frequency
(38 KHz) IR formats generated by most universal remote control transmitters. This
port supports RC5 IR control and some IR control codes from Sharp Electronics
Corporation.
The four IR outputs (A – D) are used to control either IR or one-way serial devices,
not both. These outputs can also be connected to optional Crestron equipment such
as the STIRP, ST-MB, ST-SPL, SP-RY, and SP-SC.
SENS
The CNXRMC contains a contact closure type input accessed via this two-pin
connector. The port can be connected to a Crestron current sensor (CNXRMCS) or
