4 Programmable TV/AV Controller: CN-TVAV
CRESNET
This 6-pin, 6-position RJ11 modular jack is used to connect the CN-TVAV to a
control system so it may be accessed as a Cresnet peripheral. Refer to the table
below for the pinouts.
CAUTION: If making connections to RJ11 ports, use the Crestron 6-conductor
modular cable provided, do not use 6-conductor telephone cables. Telephone cables
are wired in a crisscross fashion and are not compatible with Crestron equipment.
For further information, refer to the latest revision of Modular Cable Requirements
(Doc. 5682). This document can be obtained from the Products page (PRODUCT
MANUALS section, manuals for software and wiring diagrams section) or
Downloads page (CABLES and MANUAL Libraries) of Crestron's website
(www.crestron.com). Search for MODULAR.PDF. New users are required to
register in order to obtain access to the FTP site.
NOTE: This port does not provide 24 direct current volts (VDC) for powering other
equipment.
CRESNET Port Pinouts
PIN DESCRIPTION
1 * Not Connected
2 Not Connected
3 Net+ (Cresnet Y data)
* While facing the rear panel of the unit, pin 1 is located at the upper-left of the port.
RS-232
This 6-pin, 6-position RJ11 modular jack is used for control of RS-232 peripheral
devices and to communicate with a personal computer (PC) when programming the
CN-TVAV. Prior to switching between the programming mode and the RS-232 port,
refer to "Special Considerations for Using the RS-232 Port for Uploading Programs"
on page 10. Refer to the table below for the pinouts.
RS-232 (PC) Port Pinouts
PIN DESCRIPTION
1 * CTS (Clear to Send)
2 GND
3 RxD (Received Data)
* While facing the rear panel of the unit, pin 1 is located at the upper-left of the port.
I/O (1-4, G)
Pins 1-4 of this Versiport may individually be used as programmable digital inputs,
digital outputs, analog inputs, or any combination of each. Digital inputs are rated
0 - 24VDC, 20K ohms input impedance, logic threshold 1.25VDC. Digital outputs
offer 250 milliamp sink from maximum 24VDC; catch diodes provide transient
protection for use with "real world" loads. Analog inputs are rated 0 - 10VDC,
protected to 24VDC maximum, 20K ohms input impedance; pin-programmable 2K
ohms pullup resistor to +5V. The pin labeled G is the common ground for pins 1-4.
IR
This 3.5mm mini-jack is used by the STIRP (provided) to control an attached TV or
AV device. The jack accepts mono (2-conductor) or stereo (3-conductor) mini-plugs.
Multiple IR drivers may be loaded into the CN-TVAV and, with the use of a
Crestron ST-SPL IR Splitter, up to five AV devices may be controlled.
